This profile includes hemoglobin variant identification by Capillary Electrophoresis. All reports include either a technical comment or pathologist interpretation. If additional testing is necessary to identify rarer variants, they will be performed as required.
Methodology
Electronic Sizing and Counting/Cytometry • Capillary Electrophoresis followed by, if necessary, High Performance Liquid Chromatography, Solubility
Specimen requirements | |
|---|---|
| Patient preparation | None Specified |
| Preferred specimen(s) | 5 mL whole blood collected in an EDTA (lavender-top) tube |
| Minimum volume | 1 mL |
| Collection instructions | Please note: If only normal Hemoglobin's are detected, the results will be reported within 24 hours. However, if any abnormal Hemoglobin's are present that require additional testing, turnaround time may take as long as 5 days. Specimens for Hemoglobin by HPLC are stable for 7 days at refrigerator temperature. However, if Hemogram is needed for accurate interpretation, the Hemogram portion is only stable for 3 days from the time of collection at refrigerator temperature. |
| Transport temperature | Room temperature |
| Specimen stability | Room temperature: 72 hours Refrigerated: 7 days Frozen: Unacceptable |
| Reject criteria | Hemolysis • Clotted |
