The Sickling Test is a simple, rapid screening test for sickle cell disease and sickle cell trait. This test takes a sample of your blood and exposes it to a special solution with low oxygen. If the sickle cell hemoglobin is present, this will force the red blood cells to change into the characteristic "sickle" shape, which our lab can see under a microscope. This is a vital, proactive screening for you and your family to understand your genetic status.
