Nucleic Acid Testing (NAT)

Nucleic Acid Testing (NAT) is a laboratory method used to detect the genetic material (DNA or RNA) of viruses or other pathogens in a sample, such as blood or tissue. It is highly sensitive and can identify an infection even at very early stages, before symptoms appear. NAT works by amplifying the target genetic material to detectable levels, enabling quick and accurate diagnosis. It is commonly used for testing for infections like HIV, hepatitis, and COVID-19, helping healthcare providers diagnose and manage diseases more effectively.
