These protocols recommend 1) confirmation of all reactive rapid HIV test results with either Western blot (WB) or immunofluorescent assay (IFA), even if an enzyme immunoassay (EIA) screening test is negative, and 2) follow-up testing for persons with negative or indeterminate confirmatory test results, with a blood specimen collected 4 weeks after the initial reactive rapid test result.

The judge ruled that the patents were "improperly granted" because they involved a "law of nature." The patents over the BCRA1 and BCRA2 genes allowed Myriad Genetics, the company that holds the patents with the University of Utah Research Foundation, to charge $3,000 for a screening exam to detect cancerous mutations to the genes, and prevented other organizations from developing alternative tests, which prevented women from getting a confirmatory test from another laboratory.
