Proficiency Solutions

Partner with Microbiologics for your PT Controls

The Proficiency Solutions division of Microbiologics provides custom microbiological controls for large ISO-certified proficiency testing facilities. We supply ISO accredited proficiency companies with bacterial samples used to challenge their participants. We also provide materials for labs to perform internal competency challenges; however, we are not able to analyze results or assist in the grading of these internal evaluations.

As a control manufacturer, we do not manage proficiency testing events. We work directly with certified proficiency providers who carry out routine proficiency testing challenges. If you wish to perform your own internal competency challenges, contact us to request a quote.

We develop PT controls from our Saint Cloud, MN and Lexington, KY locations. Our Saint Cloud global manufacturing distribution center provides culture collection for clinical, molecular, food, environmental and cosmetic/pharma, while our Lexington custom manufacturing center provides clincial isolates. Contact us to learn more.
