Gross lipemia. Hemolysis can interfere with assay.
Collection Comments
Do not collect in Orange Tube. Allow Gold tube to sit for 30 minutes to form clot. Spin for 10 minutes at 1100-1300 g in a swing bucket unit or 15 minutes in a fixed angle to separate cells from serum. Refrigerate spun tube. Remember to properly label tube with patient name, DOB, test and collect date. If collecting in Red, spin, separate, transfer serum to aliquot tube and refrigerate.
Storage/Transport Temperature
Refrigerated serum
Stability (from collection to initiation)
After separation from cells: Refrigerated: 7 days; Frozen: indefinitely
Ordering Recommendations
The Ribosomal P Ab EIA test uses an enzyme immunoassay test to detect auto-antibodies to ribosomal protein P. These autoantibodies are highly specific (but relatively insensitive) when applied to the diagnosis of systemic lupus erythematosus (SLE). Thistest may be ordered when there is a suspicion of SLE and, if present, this antibody may indicate that the patient with SLE has central nervous system involvement from the disease.
