A 3-year-old boy is brought to the clinic by his mother. She is concerned because the patient has complained of a sore throat over the past 4 days. He is not in day care and has had no known sick contacts. His 7-year-old sister is currently healthy. The physician does a throat swab for a rapid streptococcal test and sends a second specimen for culture. Why does the physician perform both tests?
(A) The culture may grow strains of bacteria which are not detected by the rapid test
(B) The rapid streptococcal test and culture both have high sensitivity
(C) The rapid streptococcal test and culture both have high specificity
(D) The rapid streptococcal test has a high sensitivity, while the culture has high specificity
(E) The rapid streptococcal test has a high specificity, while the culture has high sensitivity
