red and swollen, and he has pus pockets on his tonsils. John experiences pain upon swallowing.

Rapid Strep test (RST) is used to diagnose pharyngitis infection caused by “Group A Streptococci” (GAS).
The kits contain strips with antibiotics specifically against the proteins found on GAS. A positive result
will show two bands on the strip, and a negative result will show only one band. However, this test is not
always conclusive.

The nurse takes two swabs cultures of throat- with first she performs rapid Strep test, which shows two
bands.
4. Is the result positive or negative? Explain your rationale (1 point)
The result would be positive because two bands appeared on the test, indicating that it is
positive.
Next the nurse sends the second swab to clinical laboratory. She informs John’s mom that the test will
take two days, but John will need to start on antibiotics right away.
