Alias:

This panel includes SSA, SSB, Sm, RNP, Jo 1 and Scl 70 antibodies.

Methodology:

Multiplex Flow Immunoassay (MFI)

Performed:

Monday through Friday

Analytical Time:

1 day

Testing Laboratory:

Pathology Laboratory

Laboratory Section:

Core Laboratory

Antibody to Extractable Nuclear Antigens (ENA) Evaluation

Preferred Collection Container:

SST (Serum Separator)

Also Acceptable Collection Container:

Red (No Additive)

Collection Information:

Collect blood in a SST (Serum Separator). Red (No Additive) also acceptable.

Transport Information:

Centrifuge and aliquot 1.0 mL of serum into a plastic transport vial. Send refrigerated.

Minimum Sample Volume: Minimum amount of analytical sample (serum, plasma, urine, CSF, etc.) required to perform an assay once. Submitting the minimum volume makes it impossible to repeat the test or perform confirmatory or reflex testing. In some situations, a minimum specimen volume may result in a QNS (Quantity Not Sufficient) result, requiring a second specimen to be collected.

0.5 mL of serum (approximately 1.0 mL of whole blood based upon a normal patient hematocrit)

Remarks:

Plasma samples from green and lavender top tubes are acceptable, but will route to a PROBL spot in the Sunquest Laboratory Information System.

Unacceptable Conditions:

Grossly hemolyzed or lipemic specimens.

Stability
