Scarlet Fever Diagnosis
In order to make a scarlet fever diagnosis, the doctor will ask a number of questions about:
- A person's possible scarlet fever symptoms
- The person's history of medical problems
- Any medications the person is taking
- Family history of recent illnesses.
The doctor will also perform a physical exam to look for signs of scarlet fever. If the doctor suspects scarlet fever, he or she may recommend certain tests to make a scarlet fever diagnosis.
The best test for diagnosing scarlet fever is a throat culture. For a throat culture, the back of the throat is rubbed with a cotton swab to see if there is a streptococcus infection (group A streptococcus is the type of bacteria that causes scarlet fever and strep throat). If the throat culture is positive for group A streptococcus and the person has scarlet fever symptoms, a scarlet fever diagnosis will be made.
