Nucleic Acid Amplification Tests (NAAT)

Nucleic Acid Amplification Tests (NAATs) are laboratory methods that detect tiny amounts of genetic material (DNA or RNA) from a virus or bacteria. They work by copying specific genetic sequences thousands to millions of times, making it easier to identify infections accurately and quickly. NAATs are highly sensitive and specific, which means they can detect infections even when the pathogen is present in very low amounts. These tests are commonly used for diagnosing diseases like COVID-19, tuberculosis, and sexually transmitted infections, providing reliable results that help guide effective treatment and public health responses.
