HelpTest Code G6PDC Glucose 6 Phosphate Dehydrogenase Enzyme Activity, Blood
Specimen Required
Only orderable as part of a profile. For more information see:
-HAEV1 / Hemolytic Anemia Evaluation, Blood
-EEEV1 / Red Blood Cell (RBC) Enzyme Evaluation, Blood
Useful For
Evaluation of individuals with episodic or chronic Coombs-negative non-spherocytic hemolytic anemia
Rapid testing to assess glucose-6-phosphate dehydrogenase (G6PD) enzyme capacity prior to rasburicase or other therapies that may cause hemolysis or methemoglobinemia in G6PD deficient patients
May aid in the creation of a comprehensive patient profile and can ensure appropriate patient monitoring for developing anemia
