Specimen Information

Patient Preparation

1. For optimal antibody detection, specimen collection is recommended prior to initiation of immunosuppressant medication.
2. This test should not be requested in patients who have recently received radioisotopes, therapeutically or diagnostically, because of potential assay interference. The specific waiting period before specimen collection will depend on the isotope administered, the dose given, and the clearance rate in the individual patient. Specimens will be screened for radioactivity prior to analysis. Radioactive specimens received in the laboratory will be held 1 week and assay if sufficiently decayed, or canceled if radioactivity remains.
3. Patient should have no general anesthetic or muscle-relaxant drugs in the previous 24 hours.
