NAAT (Nucleic Acid Test)

A Nucleic Acid Test (NAAT) is a type of laboratory test used to detect the presence of specific genetic material (DNA or RNA) from viruses or bacteria in a sample, such as a throat swab or urine. NAATs are highly sensitive and can identify infections early, even when symptoms are not present. They are commonly used for diagnosing diseases such as COVID-19, tuberculosis, and sexually transmitted infections. The test works by amplifying the genetic material, allowing for accurate identification, which is essential for effective treatment and infection control.
