Question

Quizplus · Accepted Answer

False-negative results can occur in infants younger than 3 months because their body has not yet started producing enough hemoglobin for the test to detect sickle cell disease. Prostaglandins, blood transfusions from sickle cell-positive donors, and strenuous exercise do not affect the accuracy of sickle cell disease test results.
