What tests are done to diagnose paroxysmal nocturnal hemoglobinuria (PNH)?

ANSWER

You will get routine blood tests. One will count of the number of blood cells you have. You will probably also get other tests, such as flow cytometry, which checks on whether your red blood cells have the proteins that should protect them.

Your doctor may also check your iron levels or get a sample of your bone marrow. If you have symptoms of a blood clot, they'll use other tests to look for those, too.
