HelpTest Code HGPPR Hemoglobinopathy Profile
Additional Codes
Epic: LAB3158
Quest: 8547
Specimen Required
Patient Preparation:
Specimen Type: Whole blood EDTA AND Plasma Sodium Heparin
Collection Container/Type: Lavender top (EDTA) AND Green top (Lithium heparin)
Submission Container/Tube: Lavender top (EDTA) tube AND Plastic vial
Specimen Volume: 5 mL whole blood & 1 mL plasma
Collection Instructions:
- Centrifuge sodium heparin tube within 1 hour of collection. Transfer plasma to a plastic vial.
- Send lavender samples in original collection tube, do not aliquot.
Additional Information:
- If only normal Hemoglobins are detected, the results will be
reported within 24 hours.
However, if any abnormal Hemoglobins 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.
