Analytes available in this enrollment
Optional add-on: Supplemental Set
P.I.S.S. Supplemental Sets are available for laboratories whose target analytes are not included in the standard analyte menu (see Analytes Available in This Enrollment). Select this option if you would like additional analytes incorporated into your challenge samples. Please note that the final report format and peer comparison data may vary depending on the analytes selected and the number of participating laboratories testing those compounds.
⚠️ STOP: Request approval before ordering a Supplemental Set.
Supplemental Sets are custom made and must be approved by PinPoint Testing before you order. Submit a Supplemental Set request first. We’ll reply within 4–5 business days with your confirmed analytes and next steps. Orders placed without an approved request may be canceled and refunded.
Supplemental Sets must be ordered together with a current challenge enrollment.
