Which common blood test is used to detect inflammatory, neoplastic, infectious, and necrotic processes?

A) Creatinine
B) Glucose
C) Erythrocyte sedimentation rate
D) Hematocrit

The erythrocyte sedimentation rate (ESR) test measures the rate at which red blood cells settle in a tube over a period of time. This test is commonly used to detect inflammatory, neoplastic, infectious, and necrotic processes in the body. High ESR levels may indicate the presence of an underlying condition and prompt further diagnostic testing. Creatinine and glucose tests are measures of kidney function and blood sugar levels, respectively. Hematocrit measures the proportion of red blood cells in the blood and can be used to screen for anemia or dehydration.
