 These tests are useful in a range of medical specialisms , including infectious disease , oncology , human leukocyte antigen typing ( which investigates and predicts immune function ) , coagulation , and pharmacogenomics — the genetic prediction of which drugs will work best .

 The US FDA has approved two Chagas tests , including one approved in April 2010 , and has published guidelines that recommend testing of all donated blood and tissue products . While these tests are not required in US , an estimated 75 – 90 % of the blood supply is currently tested for Chagas , including all units collected by the American Red Cross , which accounts for 40 % of the U.S. blood supply . The Chagas Biovigilance Network reports current incidents of Chagas @-@ positive blood products in the United States , as reported by labs using the screening test approved by the FDA in 2007 .

 Diagnostic criteria were developed in the late 1970s after the series of cases associated with swine flu vaccination . These were refined in 1990 . The case definition was revised by the Brighton Collaboration for vaccine safety in 2009 , but is mainly intended for research . Plasma exchange was first used in 1978 and its benefit confirmed in larger studies in 1985 . Intravenous immunoglobulins were introduced in 1988 , and its non @-@ inferiority compared to plasma exchange was demonstrated in studies in the early 1990s .
