Volume
1.5 mL
Minimum Volume
0.8 mL (Note: This volume does not allow for repeat testing.)
Temperature
Refrigerate
Unacceptable Conditions
Clotted specimen; aged, improperly stored blood samples
Methodology
Capillary electrophoresis (CE); high-pressure liquid chromatography (HPLC); Hgb Solubility: Sodium hydrosulfite reduction
Additional Information
Capillary electrophoresis (CE) is performed initially. If an abnormal hemoglobin is detected, appropriate testing will be performed at an additional charge. Depending on findings, one or more reflexive tests may be required in order to provide a clinical interpretation. These tests may include high-pressure liquid chromatography (HPLC) and/or hemoglobin solubility testing.
