Paroxysmal Nocturnal Hemoglobinuria (PNH)

A blood disease that occurs when the red cells (oxygen carrying blood cells) lose the flags that mark them as part of the body, so they get recognized as "strangers" and get destroyed. When a lot of them are destroyed, the patient develops anemia. Together with the anemia, the patients are also at risk of forming clots in unusual places like the belly. With time, all the blood cells get underproduced.

This disease is usually diagnosed using the clinical presentation and confirmed by blood, bone marrow and molecular tests.
