Howell Diagnostic Network

Welcome to the Howell Diagnostic Network

Low Cost Laboratory Testing for Healthcare Providers and their Patients

Low Cost Testing

Howell Diagnostic Network offers the lowest average pricing on laboratory testing through Quest Diagnostics. We do not make money by marking up our prices like our competitors. The price you get is the price we pay.

No More Middle Man

Howell Diagnostic Network does not make you wait days to get your questions about billing or testing answered. You have a direct account with Quest Diagnostics and you also have your own Quest representative.

The HDN Mission

We believe that all providers should have the freedom to order the labs they need to make an appropriate diagnosis independent of an insurance companies willingness to pay.
