| Interpretive Data: |
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).
Refer to Statement B under Testing Information at http://www.aruplab.com.
|
| Note: |
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. For abnormal results, we encourage consultation with the ARUP Immunology Medical Director.
Interpretation comparing the patient results to the client normal control and the laboratory control will be provided by the medical director.
