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 Chromatin Ab EIA test uses an enzyme immunoassay to measure IgG antibodies to chromatin; chromatin is the DNA/protein combination that makes up the nucleus of a cell. The chromatin antibody test may be ordered when there is a suspicion of an autoimmune disease, especially systemic lupus erythematosis.
