Sickling test

This test detects if a red blood cell inappropriately changes into a sickle shape (crescent shape) after a blood sample is mixed with a chemical that will reduce the amount of oxygen it carries.

This test is used to screen for an abnormal type of hemoglobin called Hemoglobin S in blood. Hemoglobin is a protein that helps the red blood cell carry oxygen to all parts of the body. This test is also used when other sickle cell diseases are suspected.

• Sample of whole blood
• We perform the test daily
