Mass Spectrometry Analysis Team

With careful recruiting, we have cultivated one of the best mass spectrometry analysis teams in the business. We've gone to great lengths to find analysts who are both passionate and experienced. Each and every Clinical Laboratory Technologist on our team understands our mission and is focused on providing fast accurate service.

An Exceptional Substance Abuse Testing Lab
 

A large part of being an exceptional substance abuse testing lab is doing mass spectrometry well. Much education, training, attention to detail, and number crunching is required. To do well, you must cultivate the inner scientist, the inner 'nerd' if you will. That is what we at National Laboratories provide, day in and day out. Not just test results, but the love of innovative and accurate data.
