Clinical Info

Evaluate hemolytic anemia, especially intravascular hemolysis. Plasma hemoglobin is increased with intravascular hemolysis, ABO incompatible transfusion, traumatic hemolysis, falciparum malaria, burns, and march hemoglobinuria.

Results

Result Interpretation

<5 mg/dL (if conditions are optimal). Values obtained between 5−15 mg/dL

should be interpreted with caution since such variables as suboptimal venipuncture

may increase results to this range.
 
TAT: 3 - 5 Days
