Important “Dos”
- Please, check the submission requirements for each test.
- Samples should be properly stored in vials or bags.
- Express the air out of the plastic bags to avoid parasite development that may impact results.
- Samples should be properly labeled.
- The submission form should be filled with appropriate history and requested tests, included with the sample, and/or emailed.
- Overnight shipping is ideal to avoid impact on the results.
- Cold packs should be used for fecal samples, especially in hot weather.
- Remember, we are here to assist you!
