Interpretive Data



Compliance Category

FDA

Note

If abnormal peaks suggestive of a hemoglobin variant are detected, then RBC Solubility and/or Capillary
Electrophoresis will be added to aid in confirmation and identification of the variant. Additional charges apply.
Quantitation of hemoglobin is recommended for a definitive diagnosis in infants 1 year and older.

Additional testing of detected hemoglobin variants may increase turnaround time up to 10 days.
