General Information
Alias: RBC Fragility, Erythrocytes and Red Cell Fragility
Performed: Mon-Fri
Turn Around Time: 2-5 days
CPT Codes: 85555
Performed By: Referral Lab
Notes:
Clinical Utility:
Functional testing of red blood cell sensitivity to osmotic stress; do not use to distinguish between spherocytes in hereditary spherocytosis and acquired autoimmune hemolytic anemia.
For patients with acute hemolysis, a normal red cell osmotic fragility test result cannot exclude an osmotic fragility abnormality since the osmotically labile cells may be hemolyzed and not present. Recommend testing during a state of prolonged homeostasis with stable hematocrit.
