^aReproduced from reference 347 with permission of Elsevier. Numerous antigen-based and nucleic acid-based tests are on the market. The list in this table is a partial list. The major focus in nucleic acid testing has been on multiplex tests, some of which are limited to parasites and others of which include parasites, bacteria, and viruses (341–344).

^bELISA, enzyme-limited immunosorbent assay.
