Strep Testing

What is the Strep A Test ?

Strep A, also known as group A strep, is a type of bacteria that causes sore throats and other infections.

Strep throat is an infection that affects the throat and tonsils.

The infection is transmitted from person to person through coughing or sneezing. While streptococcal throat infections can occur at any age, it is most common in children aged 5 to 15 years.

Strep throat can be easily treated with antibiotics. But if left untreated, streptococcal throat can lead to serious complications. Rheumatic fever is one of them.

What Is the Strep A Test Used For ?

The strep A test is mostly used to find out whether a sore throat and other symptoms are caused by strep throat or a viral infection. Strep throat needs to be treated with antibiotics to prevent complications. Most sore throats are caused by viruses.
