Additional Testing Requirements


In some cases, there may be local public health requirements that impact Mayo Medical Laboratories (MML) clients and require additional testing on specimens with positive results from this panel. Clients should familiarize themselves with local requirements. MML recommends that clients retain an aliquot of each specimen submitted for this test to perform additional testing themselves, as needed. If necessary, see Interpretation for detailed information about how to obtain this testing.
