• Excessive bleeding
• Fainting or feeling light-headed
• Hematoma (blood accumulating under the skin)
• Infection (a slight risk any time the skin is broken)
• Multiple punctures to locate veins

Blood transfusions within the past 3 months or iron deficiency can cause a false negative result.

Sickledex does not distinguish between sickle cell trait and sickle cell disease. Hemoglobin electrophoresis is required to distinguish between these two disorders.
