Test Panel Details


SC Labs is committed to delivering test services of the highest quality and following industry best practices. As a key component of our quality management system and ISO 17025 accreditation, we routinely inspect the performance of our analytical methods.

Changes to various panels, packages, and in some cases, individual analytes are made to either meet various state testing regulations1 or target additional analytes. Furthermore, some performance audits may prompt us to update various method parameters like limit of detection (LOD), limit of quantitation (LOQ), or measurement uncertainty.

Below are the current analytes, LODs, LOQs, and uncertainty measurement that we offer. Please check this webpage regularly, as updates are made periodically.

Items in red have been updated from previous values.

What to do next

  • Determine applicability of the analyte and measurement changes.
  • Review and update pertinent quality specifications to reflect these changes.

If you have any questions, please contact your SC Labs account manager or call (866) 435-0709.
