Important Note:

Testing must be ordered by a physician. Results can only be reported to the ordering physician or the referring laboratory. Patients desiring testing and/or test results are advised to consult their physician. We require specimen tubes to be labelled with the patient's name (first and last) and collection date. Unlabelled tubes will not be accepted for testing.  We also cannot test grossly hemolyzed samples.
