MS-2821

A 38-year-old with a known diagnosis of G6PD deficiency presents with jaundice and suspected acute haemolysis. He had recently been treated for a suspected urinary tract infection with nitrofurantoin. Blood tests reveal the following results:

Hb 94 g/L (135-180)
Platelets 210* 109/L (150 – 400)
WBC 7.2*109/L (4.0 – 11.0)
Reticulocytes 8.0% (0.2-2.0)

What underlying process is likely occurring in response to these findings?
