Guidance for Industry: Use of Serological Tests to Reduce the Risk of Transmission of Trypanosoma cruzi Infection in Whole Blood and Blood Components Intended for Transfusion
Extension without change of a currently approved collection
The guidance recommends that establishments that manufacture Whole Blood and blood components intended for transfusion should notify consignees of all previously collected in-date blood and blood components to quarantine and return the blood and blood components to establishments or to destroy them within 3 calendar days after a donor tests repeatedly reactive by a licensed test for T. cruzi antibody. When establishments identify a donor who is repeatedly reactive by a licensed test for T. cruzi antibodies and for whom there is additional information indicating risk of T. cruzi infection, such as testing positive on a licensed supplemental test (when such test is available) or until such test is available, information that the donor or donor's mother resided in an area endemic for Chagas disease (Mexico, Central and South America) or as a result of other medical diagnostic testing of the donor indicating T. cruzi infection, FDA recommends that the establishment notify consignees of all previously distributed blood and blood components collected during the "lookback" period, and, if blood or blood components were transfused, to encourage consignees to notify the recipient's physician of record of a possible increased risk of T. cruzi infection.
The notification of consignees and of the recipient's physician of record is intended to provide the necessary information regarding possible increased risk of T. cruzi infection. All donors who test repeatedly reactive should be counseled to seek a physician's advice. It also may be helpful to refer them to their state and local health departments or to other appropriate community resources.
