Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study will evaluate the accuracy of an experimental test method called nucleic acid amplification technology (NAT) in detecting human immunodeficiency virus (HIV) and hepatitis C virus (HCV). This test amplifies the nucleic acid in a virus more than a million-fold, allowing early detection of minute quantities of virus in the blood. Blood donors to the National Institutes of Health's Department of Transfusion Medicine (blood bank) will have their blood screened with transcription mediated amplification, a type of NAT test. Donors whose blood is found positive for HIV or HCV by NAT testing will be notified and asked to participate in this study. Those who agree will provide a blood sample about once a week for 3 months. The samples will be tested with additional assays to detect evidence of HIV or HCV infection. If the test results are confirmed positive, no more blood samples will be collected. The results of the tests and their significance will be explained to participants. It is anticipated that NAT screening will reduce the risk of transfusion-related HIV transmission from the current 1 in 650,000 to 1 in a million and the risk of HCV transmission from the current 1 in 100,000 to 1 in 350,000. It is possible that these tests will completely eliminate the risk of transmitting these diseases through blood transfusion.
