Hemolytic Anemia Evaluation

2-Yellow Top ACD Solution B-Whole Blood; 2-EDTA Whole Blood; 1-EDTA Whole Blood Control from Healthy Patient; 2 Well-made peripheral blood smears (Wright stained or fixed in absolute methanol)

2-ACD tubes 6 mLs (Min: 5 mLs) Whole Blood Refrigerated, 3-EDTA tubes 4 mLs (Min: 3 mLs) Whole Blood Refrigerated, Slides Ambient

1. At minimum, include recent transfusion information and most recent complete blood cell count results.
2. Metabolic Hematology Patient Information (T810) is strongly recommended, link in additional information. Testing may proceed without this information, however if the information requested is received, any pertinent reported clinical features and data will drive the focus of the evaluation and be considered in the interpretation.
3. The laboratory has extensive experience in hemoglobin variant identification and many cases can be confidently classified without molecular testing. However, molecular confirmation is always available, subject to sufficient sample quantity (eg, multiplex ligation-dependent probe amplification testing requires at least 2 mL of specimen in addition to protein testing requirements). If no molecular testing or specific molecular tests are desired, utilize the appropriate check boxes on the form. If the form or other communication is not received, the reviewing hematopathologist will select appropriate tests to sufficiently explain the protein findings, which may or may not include molecular testing.
