Friendly and helpful staff, they accommodated my special blood testing orders sent out to various third party labs elsewhere. Glad to have this place as our only option in Kalamazoo.

One of the easiest in and out drug screens I’ve ever taken. Check in to walk out, in less than 10 minutes.

We have used TestSource Lab for years. They are convenient and very easy to work with.
