Special Instructions
If a red-top tube is used for specimen collection, ensure to transfer the separated serum to a plastic transport tube for submission. The test is highly dependent on the correct transport and preservation of the specimen.
Limitations
The test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration. Due to the specialized processes involved, it is recommended to allow additional time for potential confirmatory or reflex tests to ensure accurate results. Disease and medication history may impact test results.
