Question

1. a blood test that measures protein released into the blood by damaged heart muscle is called:

cbc
troponin i.
abg.
hdl

Explanation:

A CBC (Complete Blood Count) measures blood cells, not heart muscle proteins. Troponin I is a protein specific to heart muscle that is released into the blood when heart muscle is damaged, making it the correct test. A/G (Albumin/Globulin ratio) assesses liver/kidney function, and HDL is a type of cholesterol.

Answer:

troponin I.
