What is this test?

This test measures the concentration of a substance identified as MRA in a whole-blood sample. MRA is not a universally standardized abbreviation, and the supplied test code does not specify an analysis method.

Why might I need this test?

A clinician may order this measurement to evaluate a suspected condition or monitor an established condition associated with the specific MRA substance. The reason for testing depends on the exact analyte named by your laboratory.

How is the test performed?

A blood sample is collected, usually by a vein in the arm, and the laboratory measures the amount of MRA present. The laboratory report may include the analyte’s full name and the analytical method used.

How do I prepare for the test?

Special preparation is often unnecessary for a routine blood test, but fasting or other instructions may apply depending on the exact MRA assay. Follow the instructions provided by your clinician or testing laboratory.
