The test was easy to perform, the directions were very clear, the response time was very reasonable, and the price was on point. We received our results in a very timely fashion. Consumer Reports recommended this company so I feel good about using their service.

Super convenient to order. Very easy to take a sample and send back. Only a fraction of the cost of other labs in our area.
