We’ve been submitting samples to Korva for several years. The samples need to be analyzed using our method and to our specs. We have been happy with the convenience of submission, quality of the results, rapid turnaround and reasonable pricing. I have used other analytical service providers in the past, but have switched since they offer us the best combination of the aforementioned factors.

Korva is the cream of the crop when it comes to lab testing. Since the day we first started working together, we've received nothing but excellent service. They are our go-to partner for banned substance testing and have helped certify hundreds of products for us. Their 24-48 hour turnaround time is only exceeded by the immediate help you get whenever we have had questions or needed clarifications. Labdoor could not do what we do without them!

I have used Korva for supplement testing for the past several years, and have found their accuracy, processing time and responsiveness to be unmatched.
