===== Quick Summary =====
  * **Keywords:** jiǎnyàn, 检验, Chinese word for inspect, how to say test in Chinese, examine in Mandarin, quality inspection Chinese, medical test in Chinese, product testing, scientific examination, 检查 vs 检验
  * **Summary:** Learn the Chinese word **检验 (jiǎnyàn)**, a formal verb and noun meaning "to test," "inspect," or "examine." This term is essential for understanding contexts like product quality control, scientific experiments, and medical laboratory tests. Unlike a casual "check," `检验` implies a systematic, rigorous process of verification against a specific standard. This guide will break down its characters, usage, and key differences from similar words like `检查 (jiǎnchá)` and `考试 (kǎoshì)`.
===== Core Meaning =====
<hanziwriter>检验</hanziwriter>
  * **Pinyin (with tone marks):** jiǎn yàn
  * **Part of Speech:** Verb, Noun
  * **HSK Level:** HSK 5
  * **Concise Definition:** To test, inspect, or examine something systematically against a standard.
  * **In a Nutshell:** `检验` is not your everyday, casual "check." Think of it as a formal, methodical investigation to see if something meets specific criteria. It's the word you'd use for a scientist testing a hypothesis, a factory worker inspecting a new smartphone, or a lab technician analyzing a blood sample. It carries a sense of seriousness, procedure, and definitive results.
===== Character Breakdown =====
  * **检 (jiǎn):** This character means "to check," "to inspect," or "to restrain." It consists of the "wood" radical (木) on the left, suggesting an early tool or standard, and a phonetic component on the right. The core idea is to check or review something carefully.
  * **验 (yàn):** This character means "to test," "to verify," or "to examine." It contains the "horse" radical (马). Historically, one of the most important forms of inspection was checking a horse's quality before purchase or for military use. This character captures the essence of verifying value or truth.
  * When combined, **检验 (jiǎnyàn)** literally means "to check and test." The two characters reinforce each other to create a strong, formal term that emphasizes a thorough and conclusive examination process.
===== Cultural Context and Significance =====
While `检验` doesn't tap into deep ancient philosophy, it is profoundly significant in the context of modern China. As China became the "world's factory," the concept of **质量检验 (zhìliàng jiǎnyàn)**, or "quality inspection," became a cornerstone of its economic development and international reputation. The term reflects a societal value placed on precision, standards, and accountability, especially in manufacturing, technology, and science.
In Western culture, the word "test" can be very broad, ranging from a "taste test" for a new soda to a "stress test" for a bridge. `检验` aligns with the more formal, technical end of this spectrum. It's different from a casual check, like `看看 (kànkan)` (to have a look), in the same way that a formal "inspection" by a health official is different from a friend "checking out" your new apartment. The use of `检验` implies that there is a correct answer, a pass/fail outcome, or a specific data point to be found.
===== Practical Usage in Modern China =====
`检验` is a formal term used in specific, professional, or technical contexts. You are unlikely to hear it in casual daily chat unless someone is speaking metaphorically.
  * **In Manufacturing and Quality Control:** This is one of the most common uses. It refers to the process of ensuring products meet required standards.
    * e.g., `出厂检验 (chūchǎng jiǎnyàn)` - factory inspection (before shipping)
    * e.g., `产品质量检验 (chǎnpǐn zhìliàng jiǎnyàn)` - product quality inspection
  * **In Science and Research:** It refers to the testing of a theory or hypothesis through experimentation.
    * e.g., `检验一个理论 (jiǎnyàn yī gè lǐlùn)` - to test a theory
  * **In Medicine:** It specifically refers to laboratory tests on samples (like blood or urine), not the general physical examination a doctor gives.
    * e.g., `血液检验 (xuèyè jiǎnyàn)` - blood test
    * e.g., `尿液检验 (niàoyè jiǎnyàn)` - urine test (urinalysis)
  * **Metaphorically:** It can be used to talk about "testing" abstract concepts like loyalty, love, or truth. This usage is serious and profound.
    * e.g., `时间是检验真理的唯一标准。(Shíjiān shì jiǎnyàn zhēnlǐ de wéiyī biāozhǔn.)` - Time is the sole criterion for testing truth.

===== Nuances and Common Mistakes =====
The most common mistakes for learners involve confusing `检验` with other words for "test" or "check."
  * **`检验 (jiǎnyàn)` vs. `考试 (kǎoshì)`:** This is a crucial distinction.
    * **`检验`** is for **things, samples, or ideas** (products, blood, hypotheses).
    * **`考试 (kǎoshì)`** is for **people** (an academic exam for a student).
    * **Incorrect:** 老师**检验**了我的中文水平。 (Lǎoshī jiǎnyànle wǒ de Zhōngwén shuǐpíng.)
    * **Correct:** 老师**考试**了我的中文水平。 (Lǎoshī kǎoshìle wǒ de Zhōngwén shuǐpíng.) or 老师**测试**了我的中文水平。(Lǎoshī cèshìle...)
  * **`检验 (jiǎnyàn)` vs. `检查 (jiǎnchá)`:** This is a subtle but important difference.
    * **`检查 (jiǎnchá)`** is a broader, more general term for "to check" or "inspect." It can be a simple visual check or a more involved process. (e.g., `检查作业` - to check homework; `身体检查` - a physical check-up).
    * **`检验 (jiǎnyàn)`** is more specific. It's often a type of `检查` that involves a technical or scientific procedure to get a definitive result against a standard. A doctor performs a `身体检查` (physical check-up), which might include sending a blood sample for `检验` (lab test).
    * **Think of it this way:** All `检验` are a form of `检查`, but not all `检查` are `检验`. You `检查` your car for visible problems (like a flat tire), but a mechanic might `检验` the engine's emissions.
