About us

Prompt Praxis Laboratories, LLC, founded in 2011, is a women-owned fully-integrated laboratory powered with the current information technology to facilitate rapid drug testing or development. The emphasis on automation of critical laboratory processes allows PPL to minimize human error within the testing and analysis process.

Prompt Praxis Laboratories provides a full range of rapid testing and support services focusing on pharmaceutical products and compounded sterile or nonsterile preparations. Our support activities span three major industries:

  • Pharmaceutical
  • Compounding Pharmacy
  • Medical Devices

The scope and breadth of the services we offer are extensive, and we anticipate phasing in specialty capabilities based upon the growth of our client base and diversification of development activities. Services in support of other dosage forms may be included in various expansion phases of the laboratory.

Prompt Praxis Laboratories, LLC, has developed and validated numerous Ready-to-Analyze® test methods. These methods have been validated to a typical concentration range of 1 to 50 µg/mL with short run times facilitating rapid turnaround. These methods are envisioned to be applicable without further validation to test samples after a quick specificity experiment that demonstrates their utility on the specific samples to be tested. We hope to encourage compliance with the new 503B section of the Food, Drug & Cosmetic Act by cost-effectively providing options to physicians, pharmacies, and outsourcing facilities in an effort to ensure chemically safe and effective compounded preparations.

“We want to make sure that patients get the highest quality medicine possible, which means the right molecule at the right concentration with little or no degradation.”

Lisa McChesney-Harris, PhD
CEO, CSO & Founder
