CD55 (DAF) Lymphocyte Test | Lahalak Platform
This test measures the CD55 protein, which protects your cells from accidental immune system attacks. It is crucial for diagnosing paroxysmal nocturnal hemoglobinuria and other hemolytic conditions.
Scientific name: Lymphocyte CD55 (DAF) Surface Marker Test
Flow cytometry is used to assess the expression of CD55 protein (also known as Decay Accelerating Factor - DAF) on the surface of lymphocytes and red blood cells. CD55 plays a crucial role in regulating the complement system by preventing its activation on the surfaces of healthy cells, thus protecting them from autoinfection.
