Serum or plasma substance concentration (mass concentration) for a specific protein or peptide marker

What This Test Measures

The test detects a specific protein or peptide in your serum or plasma. This protein could be involved in immune function, inflammation, or other physiological processes. The exact protein depends on clinical context, such as whether it’s screening, confirming, or monitoring a condition. Some examples include markers for kidney function, infection, or autoimmune diseases.

Why It Matters in Your Care

Elevated or low levels of this protein may signal underlying health issues, such as infections, organ dysfunction, or certain cancers. Your healthcare provider may use this test to diagnose, manage, or guide treatment for conditions like kidney disease, inflammation, or metabolic disorders.

Common Uses and Conditions

This test may be used in screening, confirmation, or monitoring for conditions like autoimmune diseases, infections, or metabolic disorders. It could also assess response to treatments or track disease progression.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The blood is processed to separate serum or plasma, which is then analyzed. Avoid eating or drinking for a specified period before the test, as certain foods or medications may affect results.
