Test results: The VLCFA test would need to be interpreted in context of the clinical reasons the test was done, and other test results (such as genetic testing if certain disorders were being considered.) If you still have questions after talking with the doctor who ordered the test, you could get an inbox consult for a 2nd opinion on HealthTap.

Stop worrying: This is a screen for a couple of uncommon genetic disorders and is seldom performed on adults. Children with one of these illnesses have high levels of one or more of these substances. You also need to know that reference ranges for most lab tests are set arbitrarily so that a few percent of healthies fall outside. Talk with whoever ordered this and I trust your anxiety will be relieved.
