Blood screening began in Bangladesh in 2000 at all hospital based Blood transfusion centres. It is the process that starts with the recruitment of safe blood donors and is followed by the mandatory screening for five transfusion transmissible infections (TTIs) which includes HIV, Hepatitis B, Hepatitis C, syphilis and malaria. Testing for TTIs started under the purview of the Safe Blood Transfusion Act 2002, which states that prior to transfusion, all blood and its products must undergo testing.
