Pennock Patients
Diagnostic Services

Understanding what is happening inside your body is the first step in helping you to get better. Diagnostic services give your doctor the tools to know what they need to properly and quickly assess your condition and start you on the path to recovery. Pennock houses four Diagnostic locations to assist with your general diagnostic, laboratory, radiology, occupational medicine, rehabilitation, and physical medicine needs; State Street Diagnostic Center, Gun Lake Medical Center, Lake Odessa Diagnostic Center, and our main Hospital.

Going for Diagnostic Testing

Most diagnostic services require a prescription from your doctor and depending on your test you may be required to schedule an appointment. For general tests such as x-rays and blood-work, you may simply walk-in for service, depending on your location of choice. Please be sure to obtain all referrals and bring prescriptions or doctor's orders if you are making the appointment yourself. For general questions, please feel free to contact us at our main Hospital number, 269-945-3451.
