A new immunology laboratory providing free or subsidised diagnostic services for economically disadvantaged patients has opened at Madras Medical Mission Hospital in Chennai. Doctors believe this initiative could significantly improve outcomes for nearly 9,000 patients currently on Tamil Nadu's kidney transplant waiting list.
Understanding the HLA Test
The Human Leukocyte Antigen (HLA) test, conducted before an organ transplant, maps the unique protein markers on a patient's cells and matches them against those of a potential donor. Nephrologist Dr Georgi Abraham explained: 'Every person carries a distinct combination of these markers, and the closer the match between donor and recipient, the lower the risk of the body rejecting the transplanted kidney. A poor match can cause the donated organ to fail, sometimes within hours of surgery.'
Beyond Pre-Transplant Matching
HLA testing is not limited to pre-transplant matching; it also detects early signs of rejection after surgery, making it an ongoing safeguard rather than a one-time screening. Dr Abraham noted: 'These high-end tests are either not available or remain inaccessible for patients.'
Funding and Accessibility
TANKER Foundation, which facilitated the laboratory with funding from Aptus Value Housing Finance India Limited, will offer tests that cost up to 40,000 rupees at private hospitals to the poor free of charge and at subsidised rates for others.
The Burden of Chronic Kidney Disease
Chronic kidney disease has emerged as a silent epidemic, affecting an estimated 17 per cent of the population — nearly one in six people — according to national health surveys. Yet fewer than 10 per cent of patients needing a transplant ever receive one, held back by donor shortages, long waiting lists, and high costs. TANKER Foundation managing trustee Latha A Kumaraswami stated: 'Patients get support from Chief Minister's Comprehensive Health Insurance Scheme, Rotary International Clubs and other philanthropists for subsidised dialysis and treatment, but there is always a need.'
