Currently the NAT, which cuts down the duration of window period drastically allowing early detection of infections, is available in a handful of city hospitals including AIIMS, RML and Apollo hospital.
The new testing and screening technology will cost Rs 800 per donor and will replace the existing ELISA test, which costs around Rs 100.
The decision to introduce the NAT for blood transfusion was taken at a cabinet meeting presided by Chief Minister Sheila Dikshit.
The ELISA test detects infections in respect of HIV, Hepatitis B and Hepatitis C viruses in the donated blood after approximately 21, 60 and 75 days of infections respectively. The period is known as window period.
