Orderable Name EEEV1 Red Blood Cell (RBC) Enzyme Evaluation, Blood
Necessary Information
Metabolic Hematology Patient Information (T810) is strongly recommended and should include clinical history. Testing may proceed without this information, however if the information requested is received, it allows for a more complete interpretation.
Specimen Required
Container/Tube:
Preferred: Yellow top (ACD solution B)
Acceptable: Yellow top (ACD solution A)
Specimen Volume: 12 mL
Collection Instructions: Send whole blood specimen in original tube. Do not aliquot.
Forms
1. Metabolic Hematology Patient Information (T810)
2. If not ordering electronically, complete, print, and send a Benign Hematology Test Request (T755) with the specimen.
Useful For
Identifying defects of red blood cell enzyme metabolism
Evaluating patients with Coombs-negative hemolytic anemia
