Melissa visits the laboratory, where a technologist draws her blood and takes two throat swabs. The technologist analyzes one throat swab and results indicate that Melissa does not have strep throat. To ensure accuracy and avoid iatrogenesis, the second throat swab is tested by throat culture, confirming the original results. The technologist then prepares the blood sample for a Epstein-Barr Virus (EBV) Antibody Panel. Melissa’s blood shows higher-than-normal antibodies for EBV – high counts are commonly found when someone has contracted EBV, which causes infectious mononucleosis (mono). The technologist enters the test results into Melissa’s EHR for Dr. Smith to review.
