Guidance on Testing for Paroxysmal Nocturnal Haemoglobinuria

Guidance on Testing for Paroxysmal Nocturnal Haemoglobinuria

Paroxysmal Nocturnal Haemoglobinuria (PNH) is an acquired haematopoietic stem cell disorder resulting in a partial or total deficiency of proteins normally linked to cell membranes by a glycosylphosphatidylinositol (GPI) anchor. Classical features are;

  • intravascular haemolysis
  • bone marrow failure
  • thrombotic tendency
  • may also include abdominal pain, dysphagia, erectile dysfunction, renal failure, lethargy

It can often go undiagnosed for months or even years. Flow cytometry can provide a definitive diagnosis.
