Kephera Diagnostics’ CLIA laboratory adds third “tiebreaker” Chagas test in celebration of World Chagas Day

For World Chagas Day on April 14th, Kephera Diagnostics announced the addition of a third serological test for Chagas disease, the TESA immunoblot, to its CLIA-certified, CAP-accredited clinical laboratory test menu.

The current algorithm for Chagas serodiagnosis requires two concordant results on tests using different antigens or approaches. In the event of disagreement between the two tests, a third tiebreaker test is required. With the addition of the TESA immunoblot to its CLIA test offerings, Kephera is now able to provide definitive Chagas serodiagnosis for all clinical samples, offering two of the same Chagas tests as the CDC Parasitic Diagnostic Reference Laboratory.

The TESA immunoblot is based on electrophoretically separated Trypomastigote Excreted-Secreted Antigens and has been shown to have high sensitivity and specificity (between 97-100%) in research-use settings.
