What is this test?

This is a quantitative blood test that measures the mass concentration of a substance in plasma, the liquid portion of blood. The analyte code “AAA” is not a standard, unambiguous LOINC abbreviation, so the specific substance should be confirmed with the ordering laboratory.

Why might I need this test?

Mass-concentration tests may be used to evaluate a substance associated with a particular condition or to monitor treatment. The reason for testing depends on the substance actually intended by the “AAA” code.

How is the test performed?

A blood sample is collected, and the plasma is separated and analyzed using a validated laboratory method. No specific measurement method is identified in the abbreviated test code.

How do I prepare for the test?

Follow the instructions provided by the ordering clinician or laboratory. Preparation varies with the substance being measured, so it is important to confirm the exact analyte before the sample is collected.

Clinical interpretation

Frequently asked questions

What substance does “AAA” refer to?
“AAA” is not a standard, unambiguous analyte abbreviation in the provided code. The ordering laboratory or healthcare provider should confirm the intended test name.
Does this test require a blood sample?
Yes. The code identifies plasma as the specimen, so a venous blood sample is generally collected and the plasma is separated for analysis.
How should I interpret the result?
The meaning depends on the substance measured and the laboratory’s reference interval. A clinician can review the result in the context of your symptoms, medications, and other tests.
