The Supreme Court is considering whether the Nucleic Acid Test (NAT) should be compulsory in all blood banks, as part of ensuring safe transfusion under Article 21.
- NAT is a molecular test that detects viral genetic material (DNA or RNA) in donated blood, catching HIV, Hepatitis B and Hepatitis C early.
- It narrows the "window period" compared with the ELISA tests widely used in India.
- The petition contends that safe blood is part of the Right to Life under Article 21.
- The Court has sought data on cost, State-wise implementation and feasibility before deciding.
