LAB TEST

Ham test

The Ham test is a blood test to diagnose paroxysmal nocturnal hemoglobinuria (PNH). This rare condition causes red blood cells to die before they should. The Ham test checks whether red blood cells become more fragile when they are placed in mild acid. Today, the Ham test has been replaced by a test that uses flow cytometry to diagnose PNH.
