about us

TestSource Lab is a lab outreach company located in Kalamazoo Michigan that is designed to offer individuals, employers and those involved with the courts direct access to a huge variety of lab services all in one place.


TestSource Lab works with all major reference laboratories in the US to provide testing services for drugs, alcohol, DNA, clinical diagnostics and TB tests for everyone.  The labs provide us with their education and training to help apply the best tests and methodology for you.


Many of the services are conducted at our Kalamazoo Michigan location but if the specimen requires further analysis, we send them to one of the highly complex reference labs for processing.  We are happy to conduct mobile tests at employer locations.


We work with employers, attorneys, courts and private individuals throughout Southwest Michigan to provide comprehensive and cost-effective drug, alcohol, DNA & clinical testing services.
