What type of specimen is required for a strep A evaluation?

  1. Blood sample

  2. Urine sample

  3. Throat culture

  4. Saliva sample

The correct answer is: Throat culture

A throat culture is required for a strep A evaluation because strep A is a bacteria that commonly infects the throat. A blood sample would not be sufficient for detecting this specific type of bacteria. A urine sample would also not be useful as it would not contain any throat bacteria. While saliva may contain some bacteria from the throat, a throat culture is more accurate in identifying strep A.
