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.

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.
