Collect specimen in SST tube. Centrifuge, aliquot serum into a plastic vial and refrigerate.
If the Double-Stranded DNA antibody screen (DNAIF) is positive, a titer (DNAT) will be performed at an additional charge. By ordering this test the clinician acknowledges additional reflex testing will be performed and billed at a separate additional charge if indicated.
