Protein Interference Mean (Serum/Plasma) Concentration

What Does This Test Measure?

The test evaluates the mean protein concentration in your serum or plasma, accounting for any substances that could distort test results (e.g., certain medications, blood components, or contaminants). This helps laboratories correct for interference so other tests are reliable.

Why Might You Need This Test?

Your healthcare provider may order this test if you’re having results from other blood tests (like glucose, electrolytes, or enzymes) that seem inconsistent or unreliable. It helps identify if unusual substances in your blood are causing interference.

How Is This Test Done?

A small blood sample is drawn, typically from your arm. The lab processes the serum or plasma and calculates the average protein concentration while adjusting for interference factors. Results are compared to standard guidelines for accuracy.

What Are Common Causes of Interference?

Interference can come from medications (e.g., certain antibiotics or pain relievers), blood components (like hemolysis or lipemia), or external contaminants (e.g., improper sample handling). Rarely, conditions like severe infections or metabolic disorders may also affect protein measurements.
