Supreme Court rejects plea to make NAT test mandatory in blood banks

Context:

Recently, the Supreme Court of India refused to entertain a Public Interest Litigation (PIL) seeking to make Nucleic Acid Amplification Testing (NAT) mandatory in all blood banks across India.

Background of the Case:

• • • The PIL was filed by the NGO Sarvesham Mangalam Foundation.
      • It sought directions to:
      • Make NAT testing compulsory in all blood banks.
      • Recognise the “Right to Safe Blood” as part of Article 21 (Right to Life).
    • The plea argued that current screening methods such as ELISA may fail to detect infections at an early stage.

What did the Supreme Court say?

A bench led by Chief Justice Surya Kant declined the plea and made several observations.

• • • Policy decisions require expert assessment: The Court observed that determining whether NAT should be mandatory involves technical medical expertise and policy considerations, which courts are not equipped to decide.
    • Financial implications: The bench noted that NAT testing is more expensive, and making it compulsory nationwide could impose a significant financial burden on states.
    • Role of executive authorities: The Court allowed the petitioner to submit a representation to the Ministry of Health and Family Welfare and state health departments, which can consult domain experts and decide the matter at the policy level.

About Nucleic Acid Testing (NAT):

Nucleic Acid Testing (NAT) is a molecular diagnostic technique that detects the genetic material (DNA or RNA) of pathogens in blood samples.

Key Features:

• • • Detects infections at an early stage, even before antibodies are produced.
    • Used to identify viruses such as:
      • HIV
      • Hepatitis B
      • Hepatitis C
    • Helps reduce the “window period” during which infections may go undetected.

NAT vs Conventional Tests:

Blood Safety Framework in India:

• • • • Legal and Policy Framework:
      • Drugs and Cosmetics Act, 1940 – Regulates blood banks.
      • National Blood Policy (2002) – Aims to ensure a safe and adequate blood supply.
      • National AIDS Control Organisation (NACO) guidelines for blood screening.
    • Current Screening Methods:
      • Most blood banks currently rely on:
        • ELISA testing
        • Rapid antibody tests
      • NAT testing is available only in limited hospitals and advanced blood banks due to cost and infrastructure constraints.

Conclusion:

The Supreme Court’s decision reflects judicial restraint in technical policy matters while highlighting the need for expert-driven decisions in public health. Although NAT testing can significantly enhance blood safety, its nationwide implementation requires careful evaluation of costs, infrastructure, and public health priorities.
