Sickle cells are some of the most readily identifiable abnormal red blood cells that may be encountered on a manual differential and observation of them will assist in the positive identification of a hemoglobin S disorder. However, they are not present in all hemoglobin S disorders, or may not be present in all stages of a disorder.

This course will update you on the laboratory testing that is currently being used to diagnose and differentiate between the various forms of hemoglobin S disorders. You will also learn about the clinical symptoms that are associated with each one.

The course concludes with several case studies that will provide you with the opportunity to apply what you learned in the course.
