Heinz body


5 mL blood in EDTA.


Fresh blood incubated with supravital stain and examined by microscopy for presence of stained inclusions close to the red cell membrane (Heinz bodies).

Reference Interval:

Not detected.


Investigation of haemolysis (when oxidative changes seen on blood film) or with history of exposure to oxidant chemical or drug.


Heinz bodies are denatured globin, and represent the end-product of oxidative degradation of haemoglobin.

Heinz bodies may be detected post-splenectomy, with oxidative haemolysis (in normals, but particularly in patients with G-6-PD deficiency) and in patients with unstable haemoglobinopathies.
