Combs Test, Direct (= Direct Antiglobulin Test - DAT)
Used to determine cause of anemia (autoimmune vs drug-induced) and in assessment of transfusion compatibility
Should be negative
Glucose-6-phosphate dehydrogenase
5 - 14 units / gram
Used to determine if anemia is due to G6PD deficiency (the result will be low)
Diabetes tests
- Fasting plasma glucose (FPG)*
- Hemoglobin A1C (A1C)*
- Estimated Average Glucose (eAG)
- Preprandial blood glucose
- Postprandial blood glucose
- C-peptide (fasting)*
- Urinary Albumin Excretion (UAE)*
- Urine Albumin to Creatinine Ratio or Albumin to Creatinine ratio (UACR or ACR)
Fasting plasma glucose values
> = 126 mg/dL: positive for diabetes
100-125 mg/dL: positive for pre-diabetes
Note: fasting is 8+ hrs
Hemoglobin A1C (A1C) test values
<7% (ADA)
<= 6.5% (AACE)
C-peptide (fasting) test values

C-peptide = insulin byproduct (breakdown product) used to evaluate beta-cell function => distinguish type 1 from type 2 diabetes
Note: !!! # C-reactive protein
