Serum/plasma concentration of a specific protein marker detected via immunoassay (tetramethylbenzidine-based) probe

What This Test Measures

The test detects the presence and concentration of a specific protein in your blood using a sensitive immunoassay method. This protein may be associated with conditions like chronic inflammation, immune system activity, or other metabolic processes. The exact protein is not specified here, but it is measured through a chemical reaction that produces a measurable signal (tetramethylbenzidine).

Why It’s Done

Your healthcare provider may order this test to evaluate conditions such as autoimmune diseases, infections, or other systemic processes where protein markers can provide important clues about your health. It may also be used as a screening or confirmatory test for certain conditions not fully captured by other lab tests.

Sample Collection

A blood sample is drawn from a vein, typically in your arm. The blood is collected in a tube that separates serum (liquid part) or plasma (whole blood minus clotting factors) for testing. You may experience a brief pinch or discomfort during the draw, but it usually lasts only a few seconds.

Test Process

The blood sample is processed to isolate the protein of interest. The immunoassay method involves mixing the sample with specific antibodies that bind to the protein, followed by a chemical reaction that generates a detectable signal. This signal is measured to determine the protein concentration.
