Streptokokker gruppe A

Streptococcus Group A refers to a category of bacteria primarily responsible for causing strep throat and other serious infections. Testing is important because it helps confirm the presence of these bacteria, allowing for targeted antibiotic therapy which can prevent complications and reduce the spread of the infection.

Testing for Streptococcus Group A is recommended for individuals presenting symptoms of strep throat, which include severe and sudden sore throat, pain when swallowing, fever, swollen lymph nodes in the neck, and white patches on the tonsils. It’s also advised for those with symptoms of other Group A streptococcal infections, such as skin rashes or necrotizing fasciitis.

Positive test results typically lead to the immediate start of antibiotic treatment to reduce the duration of symptoms, prevent the spread of the infection, and decrease the risk of developing severe complications. Negative results may lead to further investigation for other causes of the symptoms or additional testing if strep throat is still strongly suspected.

False negatives can occur with rapid tests if the bacterial load is too low to detect, which is why a follow-up throat culture is recommended if initial results are negative and symptoms persist. False positives are rare but can occur if there is contamination of the sample or if the test kit is mishandled.
