Initial Chagas serologic screening is now being performed at the DSHS Austin Laboratory. All results will be reported back to the submitters. Serum specimens with positive, equivocal, and inconclusive results will be forwarded to the CDC for additional confirmatory testing.
Additional information about this testing service can be found at [Link to new Chagas IgG LTSM test page.
Providers can use a commercial laboratory for Chagas serologic screening. If testing is performed at a commercial laboratory, specimens with positive results must be submitted to DSHS for routing to CDC, where confirmatory testing will be performed. In cases where insufficient amount of the original specimen remains, providers should collect another specimen from the patient and submit it to DSHS.
Note: Only serum specimens are forwarded to the CDC for confirmatory testing. Providers who submit plasma specimens to DSHS that return positive, equivocal, or inconclusive results must collect a serum specimen from the patient and submit it to DSHS for confirmatory testing at CDC.
