Purchase our testing kits and send us your samples for authoritative, accurate quantitative testing:
CWC Labs tests nutritive minerals and toxic heavy metals using ICP-MS instrumentation capable of sub-parts per billion detection.
Glyphosate, AMPA, pesticides and agricultural chemicals are tested via LC-MS-MS (triple quad mass spec) using ion fragment quantitation and confirmation protocols.
Note: CWC Labs does not test biological liquid samples such as urine, blood or breast milk. We do, however, test hair for heavy metals.
CWC Labs is ISO-17025 accredited, which is the "gold standard" for analytical testing accuracy.
