CD59 (Protectin) Lymphocyte Test | Lahalak Platform
A test for the CD59 protein, which prevents the destruction of healthy blood cells by the immune system. Low levels are a key indicator of specific chronic hemolytic anemias.
Scientific name: Lymphocyte CD59 (Protectin) Surface Marker Test
Flow cytometry is used to assess the expression of CD59 protein (also known as Protectin or MAC-IP) on the surface of lymphocytes and blood cells. CD59 acts as a final inhibitor of the complement system's membrane attack complex (MAC), preventing cell lysis. Its measurement is essential for the diagnosis of paroxysmal nocturnal hemolytic anemia (PN...
