G6PD and anemia (phenotype): This can also establish the need to include a G6PD test among the battery of tests for neonates presenting with non-specific signs and symptoms of G6PD deficiency, such as prolonged jaundice (often the first week of life), anaemia, hyperbilirubinaemia, sudden jaundice, haemoglobinuria, poor feeding, lethargy, tachycardia, and others, thus helping in the early establishment of correct diagnosis and treatment, and thereby helping to reduce the morbidity and mortality resulting from G6PD deficiency.
