If you test the blood that is donated, why do you have such a lengthy screening process?

Australia has one of the safest blood supplies in the world and the Blood Service needs your help to maintain these standards. All blood donations are tested for viruses including HIV, hepatitis B & C, however there is a period of time after a person first becomes infected with a virus during which the infection may not be detectable (often referred to as the ‘window period’). So, the person’s blood could still transmit a disease if transfused to a patient, even though their tests were negative and there was no sign of infection at the time of donation. Also, tests are not available for infections such as vCJD (mad cow diseases). For this reason, a thorough screening process is essential.
