Additional Codes
| Hospital Order Code |
| Lab2608 MISMGO |
Necessary Information
Metabolic Hematology Patient Information (T810) is strongly recommended and should include clinical history. Testing may proceed without this information; however, if the requested information 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
