What is a rapid strep test looking for in a throat swab?

The rapid strep test is specifically designed to detect the presence of Group A Streptococcus bacteria in a throat swab. This group of bacteria is the primary cause of strep throat, a common throat infection characterized by symptoms such as sore throat, fever, and swollen lymph nodes. By identifying the presence of these bacteria quickly, healthcare providers can determine the appropriate treatment, typically antibiotics if the test is positive.

Fungal infections, general viral infections, and all types of bacteria are not the target of the rapid strep test. The test is exclusive to Group A Streptococcus, making it vital for diagnosing strep throat accurately and promptly. This specificity allows for efficient management of the condition and reduces the risk of complications associated with untreated strep throat, such as rheumatic fever or post-streptococcal glomerulonephritis.
