PFAS 40-Analyte Total Oxidizable Precursor (TOP) Assay Water Test Kit

A TOP (Total Oxidizable Precursor) Assay provides a great means to understanding the total level of PFAS contamination in your drinking and non-potable water. This procedure screens the 40 PFAS analytes specified in EPA Method 1633A. It is also able to identify other PFAS that can oxidize to these compounds that are not detectable using traditional EPA methods. TOP assay samples are tested and validated using a DOD Labs internally-validated method.

This convenient kit provides everythying you need to collect and return your sample to us from your work, home or other remote location. Our analytical lab will test and produce a professional, comprehensive report (posted to your secure personal portal) with detailed results. 

NOTE: A commercial invoice is required for customs when shipping internationally. 

What's Included

  • Two sample collection bottles (for sampling from the same source - see instructions
  • Sanitary rubber gloves
  • Instruction card with link to "Activate The Kit"
  • Pre-paid return shipping label (when returning within the contiguous U.S.; contact us to inquire about shipping outside of this range or other international shipping options)
  • Re-usable shipping carton and tape for easy re-packing and return
  • Fast, accurate results with a downloadable report posted to your personal portal

Comprehensive Reports

Our PFAS reports examine analytes measured in parts per trillion (ppt). Results are provided based on Limits of Qualification (LOQ). Each LOQ represents the lowest concentration of a substance that can be reliably measured with acceptable accuracy and precision. This analysis will help you determine your level of exposure and serve as a guide to taking further action. The report image shown is only an example as the content (and results) will vary by test.
