justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The Supreme Court has agreed to examine whether the Nucleic Acid Test (NAT) should be made compulsory in blood banks to ensure safer blood transfusion practices.\u00a0<\/span><\/li>\n<\/ul>\n<h2 style=\"text-align: justify;\"><strong>Background of the Case<\/strong><\/h2>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The matter came before a Bench of the Chief Justice of India and two other judges after a petition was filed by an NGO seeking mandatory implementation of NAT across blood banks in India.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The petitioner argued that the right to safe blood transfusion forms part of the fundamental right to life under <\/span><b>Article 21 of the Constitution<\/b><span style=\"font-weight: 400;\">.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The plea emphasised that NAT is a safer and more sensitive testing mechanism compared to existing screening methods and is necessary to prevent transfusion-transmitted infections.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The Court has asked the petitioner to submit additional data on cost-effectiveness, State-level implementation, and feasibility before taking a final view.\u00a0<\/span><\/li>\n<\/ul>\n<h2 style=\"text-align: justify;\"><strong>What is the Nucleic Acid Test (NAT)<\/strong><\/h2>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Nucleic Acid Test (NAT) is a highly sensitive molecular diagnostic technique that detects the genetic material (DNA or RNA) of viruses in donated blood.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It is capable of identifying infections such as <\/span><b>Human Immunodeficiency Virus<\/b><span style=\"font-weight: 400;\"> (HIV), <\/span><b>Hepatitis B<\/b><span style=\"font-weight: 400;\">, and <\/span><b>Hepatitis C<\/b><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Unlike traditional serological tests, NAT reduces the \u201cwindow period\u201d, the time between infection and detectability, thereby enhancing blood safety.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Currently, many blood banks in India primarily use <\/span><b>Enzyme-Linked Immunosorbent Assay (ELISA)<\/b><span style=\"font-weight: 400;\"> tests, which are less expensive but comparatively less sensitive during early infection stages.<\/span><\/li>\n<\/ul>\n<h2 style=\"text-align: justify;\"><strong>Constitutional Dimension and Right to Life<\/strong><\/h2>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The petitioner has argued that access to safe and infection-free blood is an integral component of the right to life under Article 21.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The Supreme Court has previously interpreted Article 21 expansively to include the right to health, medical care, and dignity.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In this context, ensuring safe blood transfusion aligns with the constitutional obligation of the State to protect public health.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The Court\u2019s decision to examine the issue indicates recognition of the broader public health and human rights implications.<\/span><\/li>\n<\/ul>\n<h2 style=\"text-align: justify;\"><strong>Cost and Feasibility Concerns<\/strong><\/h2>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">During the hearing, the Bench raised questions regarding the financial feasibility of making NAT mandatory across all States.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The Court asked whether economically weaker States, already struggling with budgetary constraints, would be able to afford NAT in government blood banks and hospitals.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">While the petitioner argued that the costs of NAT are comparatively low, the Court highlighted that additional financial burdens could affect States with limited fiscal capacity.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The Bench has directed the petitioner to file an affidavit detailing:<\/span>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">Whether State hospitals currently use NAT<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">In how many hospitals is it implemented<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">The States where it is operational\u00a0<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This indicates that the Court is adopting a data-driven approach before considering mandatory nationwide implementation.<\/span><\/li>\n<\/ul>\n<h2 style=\"text-align: justify;\"><strong>Public Health Context and Recent Incidents<\/strong><\/h2>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The issue has gained urgency due to reported cases of children contracting HIV allegedly due to contaminated blood transfusions.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The petition referred to cases involving Thalassemia patients, who require frequent blood transfusions and are particularly vulnerable to infected blood.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Thalassemia is an inherited blood disorder in which the body cannot produce adequate haemoglobin. India has a high burden of Thalassemia patients, increasing the demand for safe and regular blood transfusions.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The case assumes greater significance against the backdrop of reported incidents in Madhya Pradesh and Jharkhand, where children were found HIV-positive following allegedly contaminated transfusions.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Such incidents have been described as \u201cpreventable tragedies\u201d in the petition.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">These events have reignited debate over the adequacy of existing blood screening mechanisms.<\/span><\/li>\n<\/ul>\n<h2 style=\"text-align: justify;\"><strong>Policy and Regulatory Framework<\/strong><\/h2>\n<ul>\n<li style=\"font-weight: 400; text-align: justify;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Blood safety in India is regulated under the <\/span><a href=\"https:\/\/vajiramandravi.com\/current-affairs\/drugs-and-cosmetics-act-1940\/\" target=\"_blank\"><b>Drugs and Cosmetics Act, 1940<\/b><\/a><span style=\"font-weight: 400;\">, and supervised by the <\/span><b>National Blood Transfusion Council<\/b><span style=\"font-weight: 400;\"> (NBTC) and <\/span><b>State Blood Transfusion Councils<\/b><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400; text-align: justify;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Currently, mandatory screening includes tests for HIV, Hepatitis B, Hepatitis C, malaria, and syphilis using serological methods.
