NAAT (Nucleic Acid Amplification Test)

A Nucleic Acid Amplification Test (NAAT) is a highly sensitive laboratory method used to detect specific genetic material—DNA or RNA—of a pathogen, such as bacteria or viruses. It works by making many copies of the targeted genetic sequences, even if only a small amount is present in the sample. This amplification process allows for accurate and early detection of infections like COVID-19, chlamydia, or tuberculosis. NAATs are valuable because they provide quick, precise results, helping healthcare providers diagnose and treat illnesses effectively.
