Why in News?
On July 24, 2025, the Indian Council of Medical Research (ICMR) made a crucial update to its National List of Essential Diagnostics (NLED), including rapid TB (tuberculosis) diagnostic tests for use at primary healthcare levels such as sub-health centres (SHCs) and community clinics. This move aims at early detection and treatment of TB cases, especially asymptomatic or subclinical cases, which could help reduce India’s massive TB burden.
This major development in India’s public health policy holds importance for legal, constitutional, healthcare, and policy reasoning questions in CLAT 2026, especially under the themes of Right to Health, access to care, decentralization of services, and preventive medicine.
Introduction
India bears the highest burden of tuberculosis (TB) in the world, accounting for 27% of global TB cases, according to the World Health Organization (WHO). While treatment success has improved, the emergence of multi-drug resistant TB (MDR-TB) and undetected subclinical TB remain major challenges.
The ICMR’s recent update to its National List of Essential Diagnostics (NLED) is a strategic intervention to push TB diagnostic testing down to the lowest rungs of the healthcare system. It promotes early screening at sub-health centres (SHCs) and primary health centres (PHCs) using molecular testing and TB skin tests. This decentralised approach can significantly break the chain of transmission by catching TB early — even before symptoms show.
For CLAT aspirants, this topic is essential in understanding how public health intersects with law and policy, especially in contexts like the Right to Life (Article 21) and Directive Principles of State Policy (DPSP – Article 47: Duty of the State to raise nutrition and public health).
Point-wise Summary
🔹 1. ICMR’s Updated Diagnostic List
- ICMR has revised the National List of Essential Diagnostics (NLED) to include:
- Rapid testing for sickle cell anaemia, thalassemia, hepatitis B, syphilis, and especially,
- Molecular and skin tests for tuberculosis (TB).
- This update aims to make diagnostics accessible at the grassroots level—SHCs, CHCs, and PHCs.
🔹 2. Importance of Early TB Detection
- Early TB diagnosis helps:
- Identify asymptomatic individuals.
- Prevent spread before symptoms like cough, fever, or weight loss appear.
- Detect latent and subclinical TB cases.
- The strategy recommends collecting samples at SHCs and conducting TB skin tests at the community level.
🔹 3. WHO Data on India’s TB Progress
- Since 2015, India has:
- Reduced TB cases by 17%.
- Reduced TB-related deaths by 20%.
- 85% of detected cases have received treatment, indicating effective implementation.
- However, India still contributes the largest share (27%) of TB globally.
🔹 4. Subclinical TB: The Hidden Threat
- Subclinical TB refers to infections where symptoms haven’t yet emerged.
- A study in the International Journal of Tuberculosis and Lung Disease (2024) found:
- 39% of TB cases in India were subclinical.
- These individuals can silently spread the infection, making early detection crucial.
🔹 5. The Role of SHCs and PHCs
- The ICMR update focuses on decentralising TB testing to:
- Sub-health centres (SHCs): Located in rural and semi-urban areas.
- Primary health centres (PHCs): First point of contact in rural health systems.
- Bringing TB testing to the community level can cut delays, improve access, and lower costs.
🔹 6. Strategy to Break the Chain of Transmission
- Testing individuals who show persistent cough or fatigue, even without visible symptoms.
- Early molecular tests can catch TB before it becomes symptomatic or spreads.
- The goal is to interrupt the infection chain at the community level, improving public health outcomes.
🔹 7. Government Support and Expansion
- The Indian government supports the move as part of:
- Its National TB Elimination Program (NTEP).
- Its target to eliminate TB by 2025, ahead of the global 2030 target.
- The country has expanded:
- Over 1.7 lakh diagnostic centres.
- Access to rapid testing in hard-to-reach areas.
🔹 8. Nutritional and Economic Implications
- TB is often linked to malnutrition, poverty, and poor immunity.
- Reducing TB burden:
- Lowers public health expenditure.
- Improves workforce productivity.
- Aligns with Article 47 of the Constitution (DPSP) — duty of the State to improve nutrition and public health.
🔹 9. Need for Legal Awareness & Rights-Based Approach
- Access to diagnostic tests aligns with the Right to Health under Article 21.
- Early detection is not only a health issue but a constitutional obligation in ensuring human dignity.
- Could trigger PILs for universal free testing, especially in tribal, rural, and marginalized regions.
🔹 10. Role of Judiciary & Policy Integration
- Courts have previously held that:
- The Right to Health is a derivative of the Right to Life.
- The State must take proactive steps in preventive healthcare.
- This policy could be a case study in health-related PILs, especially for environmental law and human rights law integration.
