NAT in Blood Screening
The diagnostic window
Significant reduction of the diagnostic window by NAT testing.
It takes a while until the human immune system starts its reaction against a new invader. During this time a virus is spreading within the blood without being detectable by the serological tests that are applied. As this blood has proven to be infectious in blood transfusion, NAT testing became a major technique to reduce the window period (diagnostic window) in which the virus is invisible for testing.
The diagnostic window
Impact of introduction of mandatory HCV NAT testing in 1999.
When NAT testing became mandatory for blood screening (first in Germany in 1999), it indeed showed the hoped for effect on the rate of transfusion transmitted infections (TTI). The prime example has become the risk of an HCV transmission, which dropped from a residual risk of 1 : 5,000 down to 1 : 80,000,000 ever since.
Routine testing sice 1997
International implementation of NAT testing.
The intensive research in the mid 1990-ies at the German Red Cross finally resulted in the introduction of routine NAT testing in blood screening in 1997. Building on the success of these tests the technology soon started spreading over the world complementing the serological tests in all major laboratories.
