There has never been a policy of racial profiling in the Western Cape. We collect and distribute blood/blood products without discrimination. As long as people conform to donation criteria, we will accept them as donors.
It is the time from which a person is infected with HIV (or other viruses) until the time when the virus can be detected in blood tests. The danger is that although a person tests “negative” during this period, the virus is still in their blood and can theoretically be passed on to a patient through their blood donation. Due to the new technology we’re using (NAT testing), which tests for the DNA of the virus, the window period has been reduced to 5 – 11 days.
