喜樂美語
  1. 1生物標記

    A biomarker is a chemical in your body that doctors can measure to learn something medical. It might show that you already have an illness, that you are more likely to get one, or that a treatment is working — or not. It is often read from blood, sometimes from urine, spit, or a small piece of tissue. Picture a number on a lab report that is not the illness itself, but a sign that points to it. Cancer teams watch certain proteins. Heart doctors watch other chemicals after a scare. The word is formal and belongs to hospitals and research papers; in a clinic people more often just name the test. Though actually scientists also stretch biomarker to any measurable sign of a living state, even outside medicine, but the meaning you will meet first is this one: a chemical clue inside a person.

組成From bio- (life / the living body) + marker (something that marks or shows). Marker is mark + -er.
