The above turnaround times reflect the expected time to carry out and report an immunology test. These times refer to negative/normal results.  Specimens with positive/abnormal results are often referred for further tests, which may significantly add to the turnaround time, e.g. a positive Rheumatoid Screen test (tested daily) will be referred for a Rheumatoid RAPA test (tested weekly). Some tests have long processing times, which significantly affect the turnaround time. Urgently requested ANCA and anti-GBM antibody tests will be given priority.
