# Parasite Test Types, Explained (2026)

> Stool O&P, antigen/PCR panels, blood tests by parasite—clinician-ordered, exposure-matched; no cleanse kits.

*Published 2026-07-10 · By Elena Voss*

*Medical disclaimer:* Not a diagnostic protocol. GI symptoms after travel or risky exposures need clinician care; some parasites require public-health reporting.

The short answer

Match **test method to organism and exposure**; use clinical labs—not detox kits. See [when to test](https://healthcanon.com/environmental-health/best-parasite-symptoms-when-to-test-2026) and [travel prevention](https://healthcanon.com/environmental-health/best-travel-parasite-prevention-pack-2026).

Wrong test class is a common reason “I tested negative but still feel bad” stories go viral without explaining methodology.

## How to use this roundup

Use items as a menu of test classes to discuss with a clinician—not a self-order shopping list.
