Specimen Requirements
Volume | Type | Container | Collect Temperature | Transport Temperature | Special Instructions |
---|---|---|---|---|---|
3 mL | Whole blood | Sodium or Lithium heparin (Green) | Ambient | CRITICAL AMBIENT. THIS TEST REQUIRES MULTIPLE SPECIMENS. Collect one specimen from the patient and label with the patient Beaker label. Collect an additional specimen from an unrelated healthy person; label with the patient Beaker label and write that it is the "Control." Deliver both tubes to the Send-Outs laboratory on the day of collection by 3 p.m. Patient and control specimens must be collected within 48 hours of test performance. Do NOT refrigerate or freeze as live neutrophils are required. | |

Special Info
CRITICAL AMBIENT. THIS TEST REQUIRES MULTIPLE SPECIMENS. Collect one specimen from the patient and label with the patient Beaker label. Collect an additional specimen from an unrelated healthy person; label with the patient Beaker label and write that it is the "Control." Deliver both tubes to the Send-Outs laboratory on the day of collection by 3 p.m. Patient and control specimens must be collected within 48 hours of test performance. Do NOT refrigerate or freeze as live neutrophils are required. Ambient stability is 24 hours for New York clients. This test is New York DOH approved.
Clinical Info
Aids in screening for chronic granulomatous disease. White blood cells are incubated with dihydrorhodamine 123 (DHR) and catalase, then stimulated with Phorbol 12-Myristate 13-Acetate (PMA). Dihydrorhodamine oxidation to rhodamine by the respiratory burst of the cell is measured by flow cytometry. Results are reported as the ratio of the mean channel fluorescence of stimulated cells versus unstimulated cells, which yields a stimulation index (SI). If sample shows abnormal results when stimulated, and no control was sent, test should be resubmitted with control sample to validate the conditions of collection, processing and transport. Interpretation comparing the patient results to the client normal control and the laboratory control will be provided by the medical director.
