Reliable and Quick Shipping The kits we ordered for our project were delivered promptly and were very easy to use. Results even came back a little before the standard 14 day turnaround. Thank you!

Straight forward process, shipping included for testing kit, and results returned promptly as promised. Wish they offered services for other analytes.

The kit was easy to use and prepaid box worked great but the length of time to get results is a bit much.

The ease of ordering the test kit and sending it back and then the turnaround for results is really good customer service.
