Which term corresponds to the test that records the heart's electrical activity?

Explanation:
The heart’s electrical activity is captured by an electrocardiogram. This test records the electrical impulses that coordinate each heartbeat, turning them into a trace doctors read to check rhythm, conduction, and possible issues. The abbreviation EKG is commonly used for the same test, but electrocardiogram is the formal term that describes what is being measured. The other two options refer to different laboratory tests—one looks at blood cells, the other at kidney function—so they don’t relate to heart electrical activity.
