Full Form of RDT
What is RDT?
A Rapid Diagnostic Test (RDT) is a medical test that quickly detects the presence of antigens or antibodies related to a specific disease, typically within 15–30 minutes, without requiring a laboratory setting. In India, RDTs have become a cornerstone of public health initiatives, especially for diagnosing infectious diseases such as malaria, dengue, chikungunya, and COVID-19. They are widely used in primary health centres, rural clinics, and during outbreak investigations because they are portable, cost-effective, and easy to administer by trained frontline workers. RDTs play a critical role in India's disease surveillance programs, enabling early detection and timely treatment, which reduces morbidity and mortality. They are also integral to the National Vector Borne Disease Control Programme and the national response to pandemics. For students preparing for medical entrance exams like NEET or public health competitive exams, understanding RDTs is essential as topics on diagnostic methods, sensitivity, specificity, and their application in field settings frequently appear. RDTs have transformed healthcare accessibility in remote and resource-limited areas across India, bridging the gap between diagnosis and treatment.
