Serum or plasma concentration of a specific protein marker detected by immunoassay probe

What This Test Measures

The test detects a specific protein in your blood using a highly sensitive immunoassay technique. This method works by identifying the protein’s presence through a labeled probe, which reacts with the protein if it is present. The result reflects the concentration of this protein in your serum or plasma.

Why It Might Be Ordered

Your healthcare provider may order this test if they suspect a condition affecting protein metabolism, such as certain genetic disorders, autoimmune diseases, or kidney function issues. It could also be part of a broader screening or diagnostic process.

How the Test Is Performed

A blood sample is drawn from a vein, typically in your arm. The sample is then processed to separate serum or plasma, which is sent to a lab for analysis. The immunoassay probe detects and quantifies the target protein, providing a precise measurement.

What the Results Mean

Results are reported as a concentration value (e.g., in grams per liter or another relevant unit). While reference ranges vary by lab, elevated or low levels may signal potential health concerns that need further evaluation by your doctor.
