Test Details
Methodology
Multiplex flow immunoassay
Result Turnaround Time
2 - 3 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Test Includes
Anticentromere B antibodies; anti-dsDNA; antichromatin antibodies; anti-Jo-1; RNP antibodies; antiscleroderma 70 antibodies; Smith antibodies; Sjögren anti-SS-A; Sjögren anti-SS-B
Use
Detect antibodies associated with SLE and mixed connective tissue disease. Anti-Sm is highly specific for SLE. Anti-RNP is found with a variety of rheumatoid diseases. RNP, Sm, SS-A, SS-B, Scl-70, and Jo-1 are extractable nucleoprotein complexes found in the nucleus and/or cytoplasm of substrate cells.
Special Instructions
This test is intended to be used as a follow-up to Antinuclear Antibodies (ANA) Direct [164855].
