| Note: |
If HPLC detects any abnormal peaks suggestive of a hemoglobin variant, then further testing (RBC Solubility, Acid or Alkaline Electrophoresis) will be added to aid in identification and confirmation. Additional charges apply.
In infants age 1 year and older, quantitation of hemoglobin is recommended for definitive diagnosis. Abnormal hemoglobin variants may require additional testing, up to 10 days.
