Erklärung 採血 in your Level:

At the A1 level, you don't need to use the word '採血' (saiketsu) yourself very often, but you might see it if you visit a doctor in Japan. Think of it as a 'survival word' for the hospital. The word is made of two parts: 'Sai' (collect) and 'Ketsu' (blood). You can remember 'Ketsu' because it sounds a bit like 'Ketchup,' which is red like blood. At this stage, just recognize that if a nurse points to a room labeled '採血室' (Saiketsu-shitsu), they want you to go there to have your blood taken. You might hear them say 'Saiketsu shimasu,' which means 'I will take your blood.' You can respond with 'Hai' (Yes) or 'Onegaishimasu' (Please). Don't worry about the complex kanji yet; just focus on the sound and the basic meaning: 'Blood Draw.' If you are scared of needles, you can say 'Kowai desu' (It's scary).

At the A2 level, you should be able to recognize '採血' in simple written instructions, such as those for a 'Kenkō Shindan' (Health Checkup). You might see a sentence like 'Ashita wa saiketsu ga arimasu' (There is a blood draw tomorrow). You should also know how to use it with basic verbs like 'suru' (to do) or 'owaru' (to finish). For example, 'Saiketsu ga owarimashita' (The blood draw is finished). This is helpful so you know when you can leave the room. At this level, you are starting to distinguish between 'Chi' (the simple word for blood) and 'Ketsu' (the word for blood used in formal compounds). 'Saiketsu' is much more polite and professional than saying 'Chi o toru.' If you need to ask where to go, you can ask 'Saiketsu wa doko desu ka?' (Where is the blood collection?).

At the B1 level, you should be comfortable using '採血' in a variety of clinical situations. You should understand that it is a noun that often functions as a suru-verb. You should be able to explain your past experiences or future appointments using this word. For example, 'Saiketsu no ato, kibun ga waruku narimashita' (After the blood draw, I felt sick). This level requires you to understand the difference between 'saiketsu' (the act of drawing blood) and 'ketsueki kensa' (the blood test itself). You should also be able to understand instructions from medical staff, such as 'Ude o dashite kudasai' (Please put out your arm) followed by 'Saiketsu shimasu ne' (I'll draw your blood now). You might also encounter this word in the context of 'Kenketsu' (blood donation), where a 'jizen saiketsu' (preliminary draw) is performed. Being able to use this word shows that you have a functional medical vocabulary for living in Japan.

At the B2 level, you should understand the formal nuances and the various compound words associated with '採血'. You should be able to read medical forms where '採血' is listed alongside other procedures like 'X-sen' (X-ray) or 'Nyō-kensa' (urine test). You should also be able to use the word in more complex grammatical structures, such as 'Saiketsu o ukeru sai ni wa...' (When undergoing blood collection...). At this level, you should be aware of the passive and humble forms, such as 'Saiketsu shite itadaku' (to have someone draw your blood). You might also hear this word in professional or academic contexts, such as news reports about new diagnostic tools that require only a 'bi-ryō saiketsu' (minute blood sample). You should be able to discuss the necessity of the procedure and ask detailed questions about it, such as 'Saiketsu no kekka wa itsu demasu ka?' (When will the results of the blood draw be available?).

At the C1 level, you are expected to have a near-native grasp of '採血' and its technical applications. You should be able to distinguish between 'jōmyaku saiketsu' (venous) and 'dōmyaku saiketsu' (arterial) and understand the clinical significance of each. You can read medical journals or detailed health reports that discuss 'saiketsu-go no gappēshō' (complications after blood collection), such as hematomas or nerve damage. Your vocabulary should include related technical terms like 'shinkū saiketsukan' (vacuum blood collection tube). You should also be able to use the word in abstract or metaphorical contexts if they arise in literature, though the word remains primarily technical. In a professional medical setting in Japan, you would be expected to use '採血' with perfect accuracy, including the correct honorifics when speaking to patients or senior doctors. You understand the administrative side as well, such as the logistics of 'saiketsu sentā' (collection centers) and the ethics of 'jiko saiketsu' (self-sampling).

At the C2 level, '採血' is a word you handle with complete mastery, understanding its historical evolution in Japanese medical terminology and its role in the broader healthcare infrastructure. You can engage in high-level discussions about the efficiency of 'jidō saiketsu shisutemu' (automated blood collection systems) and their impact on hospital labor. You are familiar with the nuances of how the word is used in legal documents regarding medical consent and malpractice. You can effortlessly switch between the highly technical 'saiketsu' and more empathetic, patient-centered language depending on the audience. You might even know the history of how Western medicine influenced these terms during the Meiji era. For a C2 learner, '採血' is not just a vocabulary item but a node in a complex web of medical, social, and linguistic knowledge. You can critique the phrasing of medical surveys or educational materials that use the term, ensuring they are clear and culturally appropriate.

採血 in 30 Sekunden

A formal medical noun meaning 'blood collection' or 'blood sampling' used primarily in hospitals.
Commonly combined with the verb 'suru' (to do) or 'ukeru' (to undergo/receive) in clinical settings.
Essential vocabulary for navigating annual Japanese health checkups (Kenkō Shindan) and medical emergencies.
Formed by the kanji for 'collect' (採) and 'blood' (血), distinguishing it from 'donation' or 'transfusion'.

The Japanese word 採血 (saiketsu) is a formal medical noun that translates directly to 'blood collection' or 'blood sampling.' To understand its usage, we must first look at the individual kanji characters that form this compound. The first character, 採 (sai), means to pick, gather, or collect. It is the same character used in words like 採用 (saiyou - adoption/hiring) and 採取 (saishu - harvesting/collecting samples). The second character, 血 (ketsu/chi), simply means blood. Together, they form a term that specifically refers to the professional act of drawing blood from a patient for medical testing, donation, or research purposes. Unlike the more colloquial way of saying 'having blood taken' (血を抜く - chi o nuku), 採血 is the standard terminology you will encounter in clinical settings, medical reports, and health checkup invitations.

Clinical Context: In a Japanese hospital, you will frequently see signs for the '採血室' (saiketsushitsu), which is the blood collection room. This is a dedicated space where nurses or laboratory technicians perform phlebotomy. The term is treated as a Suru-verb when an action is required: 採血する (saiketsu suru) means to draw blood, while 採血を受ける (saiketsu o ukeru) means to have one's blood drawn.
Health Checkups (Kenkō Shindan): Japan has a robust system of annual health checkups mandated for employees and students. During these checkups, 採血 is a standard procedure. If you are living in Japan, you will likely receive a document listing '採血' as one of the items in your physical examination. It is a word that every resident eventually needs to know to navigate the healthcare system effectively.

健康診断のメニューには、採血が含まれています。
(Kenkō shindan no menyū ni wa, saiketsu ga fukumarete imasu.)
The health checkup menu includes blood collection.

The word is predominantly neutral and formal. You wouldn't typically use it when talking to a small child; in that case, a parent might say 'チックンするよ' (chikkun suru yo - let's do a little poke). However, for anyone over the age of ten, 採血 is the appropriate and expected term. It appears in various compound words such as 採血針 (saiketsushin - blood collection needle) and 採血管 (saiketsukan - blood collection tube). Understanding this word is crucial because it often comes with specific instructions, such as fasting (絶食 - zesshoku) before the procedure. If you see '採血' on your schedule, it is a signal to check for pre-procedure requirements.

明日の朝は、採血があるので朝食を抜いてください。
(Ashita no asa wa, saiketsu ga aru node chōshoku o nuite kudasai.)
Please skip breakfast tomorrow morning as there will be a blood draw.

Register and Frequency: In media, you will hear this word in medical dramas or news reports regarding blood shortages or new diagnostic technologies. It is high-frequency in medical contexts but low-frequency in casual daily conversation unless discussing health issues. It is a 'Level 2' or 'B1' word because while it is specialized, it is part of the common vocabulary for any adult living in a modern society.

看護師さんは手際よく採血を済ませた。
(Kangoshi-san wa tegiwa yoku saiketsu o sumaseta.)
The nurse finished the blood collection efficiently.

Using 採血 correctly involves understanding its grammatical role as a noun and its transformation into a verb. In its simplest form, it acts as the subject or object of a sentence. For instance, '採血が終わりました' (The blood collection is finished). To describe the action, you add the verb 'suru' (to do). However, the direction of the action is important. A medical professional performs the 採血, whereas a patient receives it. Therefore, a patient would say '採血をしてもらう' (to have blood drawn by someone) or '採血を受ける' (to undergo blood collection).

今日は病院で採血をしました。
(Kyō wa byōin de saiketsu o shimashita.)
I had my blood drawn at the hospital today.

When discussing the results of the blood draw, 採血 is often used as a prefix or combined with other nouns. For example, '採血の結果' (saiketsu no kekka) refers to the results of the blood test derived from that sample. Note that while '血液検査' (ketsueki kensa) is the broader term for the test, '採血' is specifically the act of getting the sample. If a doctor says, '採血しましょう' (Let's do a blood draw), they are referring to the immediate physical procedure.

Common Verb Pairings

採血を行う (okonau): To conduct blood collection (Formal/Clinical).
採血を済ませる (sumaseru): To finish/complete the blood draw.
採血に失敗する (shippai suru): To fail at drawing blood (e.g., if a vein is hard to find).
採血を控える (hikaeru): To refrain from blood collection (due to medical reasons).

血管が細くて、採血に時間がかかってしまった。
(Kekkan ga hosokute, saiketsu ni jikan ga kakatte shimatta.)
My veins are thin, so the blood collection took a long time.

In more complex sentences, 採血 can be the cause of something. For instance, '採血で気分が悪くなる' (to feel sick from/during blood collection). This is a common phrase for people who have a phobia of needles or blood. If you need to inform a nurse about this, you would use this structure to ensure they take extra care, perhaps by letting you lie down during the procedure.

採血のあとは、腕を強く押さえてください。
(Saiketsu no ato wa, ude o tsuyoku osaete kudasai.)
After the blood draw, please press firmly on your arm.

Passive vs. Active: While '採血される' (to be blood-drawn) is grammatically correct, it sounds a bit like an unwanted action. In a medical context, patients usually use '採血を受ける' (to receive/undergo) or '採血してもらう' (to have it done for one's benefit) to sound more natural and polite.

この病院では、自動採血受付機が導入されている。
(Kono byōin de wa, jidō saiketsu uketsukeki ga dōnyū saretēru.)
This hospital has introduced an automatic blood collection reception machine.

You are most likely to encounter 採血 in environments related to health and wellness. The most common location is the hospital (病院 - byōin) or clinic (診療所 - shinryōjo). Upon entering a large hospital, you might see a floor map indicating the '採血・採尿コーナー' (Blood and Urine Collection Corner). This is a high-traffic area in the morning when many outpatients arrive for their routine tests. The word is spoken by receptionists, nurses, and doctors throughout the day.

「次の方、採血室へお入りください。」
(Tsugi no kata, saiketsushitsu e ohairi kudasai.)
'Next person, please enter the blood collection room.'

Another significant place where this word is used is at a blood donation center, known in Japan as 献血ルーム (kenketsu rūmu). While '献血' refers to the act of donating blood, the actual process of checking your hemoglobin levels before the full donation is referred to as '事前採血' (jizen saiketsu - preliminary blood draw). Donors will hear staff say things like 'まず、検査のための採血をします' (First, we will do a blood draw for testing).

Workplace and School: In the spring and autumn, many Japanese companies hold group health checkups. The HR department will send out emails with a schedule. These emails will inevitably use '採血' to describe the blood test portion of the exam. For example: '10時から採血を開始しますので、5分前には集合してください' (Blood collection will start at 10:00, so please gather 5 minutes early).

In television and film, specifically medical dramas like 'Doctor-X' or 'Code Blue,' 採血 is used during emergency scenes or when discussing a patient's diagnostic data. You might hear a doctor bark an order: '至急、採血回して！' (Shikyū, saiketsu mawashite! - Rush the blood collection/analysis!). This highlights the word's role as a fundamental step in the diagnostic process. Even in news reports about health crises or new medical breakthroughs, '採血' remains the standard term for the sampling process.

最新の技術で、一滴の採血から病気が発見できるようになった。
(Saishin no gijutsu de, itteki no saiketsu kara byōki ga hakken dekiru yō ni natta.)
With the latest technology, it has become possible to detect diseases from a single drop of blood collection.

Pharmacies and Self-Checks: Recently, 'self-blood collection' (自己採血 - jiko saiketsu) kits have become popular in Japan. You might see these in drugstores. They allow people to prick their own finger and send the sample to a lab. The instructions will use '採血' repeatedly to explain how to obtain the sample safely.

薬局で、指先からの簡単な採血キットを購入した。
(Yakkyoku de, yubisaki kara no kantan na saiketsu kitto o kōnyū shita.)
I bought a simple fingertip blood collection kit at the pharmacy.

One of the most frequent mistakes English speakers make when using 採血 is confusing it with other blood-related terms like 輸血 (yuketsu) or 献血 (kenketsu). While they all share the 'ketsu' (blood) kanji, their meanings are vastly different. Yuketsu means 'blood transfusion' (receiving blood), and Kenketsu means 'blood donation' (giving blood for others). If you tell a doctor '輸血をしたい' (I want a transfusion) when you mean you need a blood test, it could lead to significant confusion!

❌ 献血の結果が心配です。
✅ 採血の結果が心配です。
(I'm worried about the blood collection results, not the donation results.)

Another common error is using the wrong verb. Beginners often try to translate 'take blood' literally as '血を取る' (chi o toru). While this is technically understandable, it sounds very unrefined and somewhat aggressive. In a medical context, 採血 is the professional noun. Similarly, don't use '飲む' (nomu - to drink) or '食べる' (taberu - to eat) just because blood is a fluid; that sounds like a horror movie! Always stick to '採血をする' or '採血を受ける'.

Confusing Nouns and Verbs: Remember that 採血 is a noun. You cannot say '私は採血した' (I blood-collected) without the particle 'o' or treating it as a suru-verb correctly. Also, be careful with the passive voice. Patients often say '採血された' (I was blood-drawn), but it is more natural to say '採血してもらった' if you are grateful for the medical service, or simply '採血があった' (There was a blood draw).

Furthermore, do not confuse 採血 with 血液検査 (ketsueki kensa). While they are related, they are not interchangeable. 採血 is the physical act of drawing the blood. 血液検査 is the entire process of testing it. If you are describing the needle part, use 採血. If you are talking about the cholesterol levels found in the report, use 血液検査. Mixing these up won't usually cause a medical error, but it makes your Japanese sound less precise.

❌ 血液検査で針が痛かったです。
✅ 採血で針が痛かったです。
(The needle was painful during the blood draw, not during the 'test' which happens in a lab.)

Pronunciation Pitfall: The 'ketsu' in saiketsu should be pronounced clearly. If you mumble the 'tsu', it might sound like 'saikei' (accounting/budget), which is a completely different world. Ensure you give each mora its due time: sa-i-ke-tsu.

While 採血 is the standard medical term, several other words share its semantic space. Understanding these will help you choose the right word for the right situation. The most common alternative in casual speech is 血を抜く (chi o nuku). This literally means 'to pull blood.' While patients use this among friends ('昨日、病院で血を抜かれたよ' - Yesterday, I had blood pulled at the hospital), it is too informal for a professional setting.

採血 vs. 血液検査 (Ketsueki Kensa): 採血 is the physical procedure of drawing blood. 血液検査 is the broader 'blood test' or 'blood analysis.' You undergo saiketsu so that the doctor can perform ketsueki kensa.
採血 vs. 採取 (Saishu): 採取 is a more general term for 'collecting' or 'sampling.' It is used for things like 血液採取 (blood sampling), 細胞採取 (cell sampling), or 証拠採取 (collecting evidence). While 採血 is specific to blood, 採取 is the scientific category it belongs to.

研究のために血液を採取した。
(We collected blood samples for research purposes.)

Another related word is 検体 (kentai), which means 'specimen.' Once the blood is in the tube, it is referred to as a kentai. Nurses might say '検体をラボに送ります' (I'm sending the specimen to the lab). Understanding this helps you see the workflow: 採血 (the act) → 検体 (the object) → 検査 (the analysis).

For specific types of blood collection, you might hear 静脈採血 (jōmyaku saiketsu) for venous blood collection (the standard arm draw) or 動脈採血 (dōmyaku saiketsu) for arterial blood collection, which is much rarer and usually done for gas analysis in emergencies. Knowing the 'saiketsu' root allows you to decipher these more complex medical terms instantly.

指先からの微量採血で、血糖値を測ります。
(We will measure your blood sugar with a micro-blood draw from your fingertip.)

Summary Comparison

採血: Clinical, specific to the act of drawing blood.
血を抜く: Casual, spoken by patients.
採取: Scientific, broad (samples of any kind).
献血: Specific to donation for others.

How Formal Is It?

Häufige Fehler

Using 'chi o nomu' (drink blood) for a blood test. → saiketsu o ukeru
Drinking blood is for vampires; 'saiketsu' is for medical patients.
Confusing 'saiketsu' with 'yuketsu' (transfusion). → saiketsu
Transfusion is giving blood to a patient; saiketsu is taking it for a test.
Saying 'saiketsu o taberu'. → saiketsu o suru
You cannot 'eat' a blood draw. Use the verb 'suru' or 'ukeru'.
Using 'saiketsu' to mean 'blood pressure'. → ketsuatsu

Tipps

Suru-Verb Usage

Remember that 'saiketsu' is a noun. To make it an action, add 'suru'. In formal settings, 'saiketsu o okonau' is better.

Health Checkups

Expect to see this word every year if you work in Japan. It's a standard part of the 'Kenkō Shindan'.

Being Polite

Use 'saiketsu shite itadaku' when talking to a doctor about the nurse who drew your blood to show respect.

Hand Radical

The 'sai' in 'saiketsu' (採) has the hand radical (扌). Think of the nurse's hand performing the procedure.

Inform the Staff

If you feel dizzy, say 'Kibun ga warui' immediately. They are trained for 'saiketsu' reactions.

Test vs. Draw

Don't confuse 'saiketsu' (the draw) with 'ketsueki kensa' (the test results). Use 'saiketsu' for the needle part.

Hospital Announcements

Listen for 'Saiketsu no kata' (People for blood draws) to know when to move to the next station.

Medical Forms

When filling out forms, 'saiketsu' is often abbreviated or listed as a checkbox. Look for the kanji 採血.

Sigh-Ketchup

Sigh (Sai) when you see the Ketchup (Ketsu). A simple way to remember the sound and meaning.

Sample Collection

In a lab, 'saiketsu' refers to the acquisition of the primary specimen.

Einprägen

Eselsbrücke

Think of a 'Sigh' (Sai) of relief when the 'Ketchup' (Ketsu) colored blood is finally in the tube and the needle is out.

Visuelle Assoziation

Imagine a nurse holding a 'Scythe' (sounds like Sai) but it's actually a tiny needle, and they are using it to harvest a 'Kettle' (Ketsu) of red blood.

Herausforderung

Try to find the '採血室' (saiketsu-shitsu) next time you visit a large Japanese hospital or look at a hospital map online. See if you can spot the two kanji in the wild.

Wortherkunft

The word is a Sino-Japanese compound (Kango). '採' (sai) originates from the Old Chinese character for 'picking' or 'gathering' (often fruit or leaves). '血' (ketsu) is a pictograph of a bowl filled with blood, used in ancient sacrificial rituals.

Ursprüngliche Bedeutung: To gather or collect blood, originally in a ritualistic or rudimentary medical sense, before modern phlebotomy.

Sino-Japanese (Kango)

Kultureller Kontext

Some people have a phobia of needles (先端恐怖症 - sentan kyōfushō). Use the word gently if you know someone is sensitive to medical procedures.

In English-speaking countries, we often say 'blood test' to cover both the drawing and the analysis. In Japan, 'saiketsu' is strictly the drawing part.

Medical dramas like 'Doctor-X' frequently feature 'saiketsu' scenes. Health posters in Japanese train stations often promote 'kenketsu' (donation) which involves 'saiketsu'. Manga characters often faint at the sight of 'saiketsu' needles as a trope.
