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
Day(s) Performed
