Serum/plasma substance concentration (qualitative) for a specific protein or marker related to serum albumin or serum protein levels (e.g., albumin fraction, protein electrophoresis profile)

What This Test Measures

This test evaluates the concentration of specific proteins or substances in your blood, typically using a qualitative method. It may include measurements of albumin, globulins, or other protein fractions, depending on the test’s scope. The results help identify imbalances that could signal conditions like kidney disease, liver dysfunction, or nutritional deficiencies.

How the Test Works

Blood is drawn and processed to separate serum or plasma. The test then analyzes protein composition, often through electrophoresis or another qualitative method. Unlike quantitative tests, this test doesn’t provide exact numbers but may flag abnormal patterns.

Common Uses

Doctors may order this test to diagnose or monitor conditions like hypoalbuminemia, protein-losing syndromes, or to screen for metabolic or genetic protein disorders.

Preparation

No special preparation is needed, but avoid heavy meals or excessive alcohol before your blood draw. Fasted or non-fasted states may not affect this qualitative test.
