![]() Studies have shown that blood donated by family members or donors selected by the patient are not safer than. While in-process testing identified approximately one ID-NAT-only detectable (antibody-negative) donation per year, reducing the geographic triggered area decreased its effectiveness. Families or friends may donate for the patient. WNV NAT's utility is between June-December however, abandoning testing outside of this time may increase risk. NAT when a predetermined threshold in the number of positive donations is reached, and then would return to minipool NAT when the rates of WNV infection fall. With reduced triggering geography, 12 of 19 (63%) were not identified (including 6/10 ID-NAT-only detectable, and 2/4 ID-NAT-only detectable/antibody negative). Ten of 19 (53%) identified in-process were ID-NAT-only detectable, including four antibody negatives, or approximately 1 per year (2.8% of ID-NAT-only detectable). Overall, 52% (358/684) required ID-NAT for detection, including 68 (19%) antibody negatives. ID-NAT included 3.2 million donations of more than 25 million tested year-round, resulting in 684 confirmed positives all confirmed-positive donations occurred from June to December (0.64/10,000). Reactive sample confirmation was performed by repeat NAT of an independent sample or antibody testing. During the MP- to ID-NAT transition, donation samples were retrieved and tested by ID-NAT for those with results not yet released (referred to as in-process testing). Current Evidence Concerning West Nile Virus In deriving an opinion on the scientific justification for further actions with respect to WNV and blood transfusion deferral, it is necessary to consider the evidence for the spread of WNV and for any change in the understanding of the maximum period of viremia. ![]() ID-NAT-triggered geographic areas included an entire state (2014-2017) or collections within a 50-mile radius of the triggering donor's residential zip code (2018). In 2002, it was found to be transmissible by blood transfusion, and within less than a year, nucleic acid testing for WNV RNA was in place for all US donations. Mini-pool-NAT transitioned to ID-NAT following triggering based on one WNV NAT-reactive donation (having an elevated signal, repeat reactive, or in an area with WNV ongoing activity). Using data from 2014 to 2018, we investigated a strategy used to increase detection early in the triggering period and reviewed its yield as the individual donation (ID)-NAT geographic area was decreased. In addition, donors may choose to purchase a fasting lipid panel and/or screening for prostate specific antigen (PSA).Results of these tests are made available in the Donor Portal section of our website approximately 72 hours after collection and will be mailed approximately two weeks after collection.Rare transfusion-transmitted West Nile virus (WNV) cases usually occur due to gaps in testing involving converting to more sensitive nucleic acid testing (NAT) formats (referred to as triggering). A list of these tests with descriptions can be found at the end of this page. We appreciate your commitment to our life-saving mission, and we are committed to supporting your good health.Įach time a person donates, our standard testing of blood is performed to help donors monitor their health as well as to protect recipients, making sure they receive the safest possible blood. If you do not have a doctor or local healthcare provider, we will provide you with some suggestions. Your health is our number one priority, and we’re taking our concern a step further with Donor CareNection! Donors who have three consecutive elevated blood pressure and/or cholesterol screenings, or who are anemic, will now be contacted through our new Donor CareNection program. You will also receive courtesy e-mail reminders regarding results, so if you do not have an e-mail on file, please let your screener know next time you donate blood to help you access results online. You may set up an online donation profile with your name as you enter it upon donation and your donor identification number. Results from your donations will be available online. Starting October 1, 2018, OBI will no longer mail letters to notify blood donors of test results, including cholesterol levels and blood pressure. Can I donate blood if I was diagnosed with West Nile virus infection If you have been diagnosed with West Nile virus by your doctor, you should not donate blood for 120 days. Any blood product found to be infected is removed from the blood supply. We report blood pressure, and cholesterol results to each donor online. All donated blood is tested for West Nile virus. We also provide important personal health screenings that are convenient for donors and beneficial as they maintain overall health.Īll donors receive mini-physicals to ensure they are healthy enough to donate blood. Our life-saving mission extends beyond providing blood for those who need it.
