What it really means
A common test where a nurse takes a small blood sample, at the surgery or a hospital blood clinic. Staff may call it "bloods". Some tests are "fasting" — no food for several hours before — so check your instructions.
Chinese explanation
验血：护士抽取少量血样化验，在诊所或医院抽血门诊进行。医护人员口语常说"bloods"。有些是空腹检查——抽血前几小时不能进食——注意看要求。
