Laboratory Testing—All in One Location

Medical tests are an important part of your healthcare. An estimated 60 to 70 percent of all decisions regarding a patient’s diagnosis and treatment are based on laboratory test results. Much of our test menu is performed on-site on the same day of your visit. This gives your provider the opportunity to communicate results of the testing to you and make the necessary decisions about your care in an efficient and timely way.

Laboratory services are available at Internal Medicine of Northern Michigan through our own Moderately Complex Diagnostic Laboratory. Performing over 150,000 tests annually, our laboratory is CLIA Certified, COLA Accredited, and recognized for excellence by the American Society of Clinical Pathology (ASCP). The laboratory is equipped with state-of-the-art automated laboratory instrumentation and staffed with Certified Medical Technologists and Phlebotomists. The Internal Medicine of Northern Michigan lab team uses its extensive experience, observation, compassion, and special bonds with patients to get results. Observations about changes in patient behavior, physicial appearance, and symptoms make a real difference in patient care.

Our laboratory is independently owned and operated by Internal Medicine of Northern Michigan.
Services are available Monday through Friday, 8 a.m. – 4 p.m.
(Please call ahead for services required around the holidays.)



Frequently Asked Questions about Laboratory Services

What Is Fasting and Do I Need to Fast?
Fasting is when you consume no food or drinks, with the exception of water, for a set period of time. It’s important to drink plenty of water, because it’s easier to draw blood from your veins when you’re well hydrated.

When your healthcare provider orders certain tests, you may be told to fast for several hours before the test or overnight.

I’m scheduled for a FASTING appointment, what do I need to  know?
If are scheduled for a FASTING appointment, your provider will order lab work AFTER your visit. Unless instructed otherwise, please follow these guidelines:

  • Nothing by mouth 8 – 12 hours prior to appointment except black coffee or tea (no sweeteners or cream).
  • Drink plenty of water to keep hydrated.
  • Take medications as directed. If you’re taking vitamin/mineral supplements, discuss whether you should discontinue.
