## Indications for use
The TECHLAB® TRl-COMBO PARASITE SCREEN test is an enzyme immunoassay for the simultaneous qualitative detection of Giardia spp., Cryptosporidium spp. and/or E. histolytica antigen in human fecal specimens. The test is indicated as an aid in the diagnosis of gastrointestinal infection when giardiasis, cryptosporidiosis and amebiasis is suspected. The test does not differentiate between the three parasites and follow-up testing is required for all positive results to confirm the specific diagnosis.
