Labcorp 2 tests

Single-analyte tests

  • Prostate-specific Antigen (PSA), Ultrasensitive 140731

    Serum · Fasting not stated · Turnaround Within 1 day

    Method and collection
    Method
    Electrochemiluminescence immunoassay (ECLIA)
    Collection
    If a red-top tube or plasma is used, transfer separated serum or plasma to a plastic transport tube.
    Reference notes
    Male: 0.000−4.000 ng/mL (Note: This interval is not intended to be used as a reference for posttreatment follow-up and monitoring of patients.) According to the American Urological Association (AUA), serum PSA should decrease and remain at undetectable levels after radical prostatectomy. The AUA defines biochemical recurrence as an initial PSA value ≥0.20 ng/mL followed by a subsequent confirmatory PSA value ≥0.20 ng/mL.

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
