1. Definitions and Genetics
The definitions for sickle cell trait (SCT) and sickle cell disease (SCD) are provided with clear differentiation between the two. The origins of sickle cell hemoglobinopathies are clarified in historical context as well as global prevalance. An explanation of how SCT and SCD are genetically passed down is provided for clinicians to use when educating their patients.
2. Testing
The two most common ways to test for sickle cell trait are described. Advantages and disadvantages of both tests are discussed for clinicians to determine which is the best option for their institution. False positive rates of each test are also provided.
3. Hemoglobin Profiles
The typical hemoglobin profiles given on lab reports are broken down into types and ranges. Atypical profiles are presented to explain their significance in relation to SCT and SCD as well as other possible hemoglobinopathies.
4. Screening
The United States’ national newborn screening mandate for sickle cell hemoglobinopathies is reviewed along with basic information for how to obtain a copy of these records. Organization mandates for SCT screening are discussed in terms of testing and education. Examples of how to integrate SCT screening into institutional policy are provided.
5. Etiology
The etiology and most common circumstances for exertional sickling are examined. The pathophysiology of how an exertional sickling event begins and how it can become a life-threatening emergency is demonstrated. Clinical ramifications of an untreated exertional sickling event are outlined.
6. Epidemiology
Research pertaining to the prevalence of SCT in active populations is presented along with evidence supporting successful training and competition. Risk of death during exercise in individuals with SCT is reported in different clinical settings.
7. Recognition
The definitions of exertional sickling events are described. Signs, symptoms, and vitals to be monitored during a sickling event are reviewed. Exertional sickling symptoms are compared to and differentiated from symptoms of other conditions that are similar.
