Clinical Laboratory Services

Ascension Crittenton Hospital Medical Center’s Laboratory staff is experience and skilled. All technicians are certified by the American Society of Clinical Pathologists, and lab inspectors are certified by the College of American Pathologists. The staff is headed by board-certified pathologists.

The Ascension Crittenton laboratory utilizes state-of-the-art instrumentation needed to aid in the diagnosis and treatment of disorders and diseases. The staff is routinely tested by the state of Michigan to maintain their expert skills.

The laboratory encompasses several subsections. They include the following:

  • Blood Bank – This area is responsible for issuing compatible blood for surgeries and emergencies. The staff also tests for Rhogam, which determines if expectant mothers are RH negative.
  • Chemistry – The Chemistry staff provides routine testing and Emergency/Operating Room support and is responsible for testing blood sugar, cholesterol, cardiac enzymes, liver enzymes, thyroid and kidney function.
  • Microbiology – This section is responsible for the testing of cultures from various locations of the body. Common diagnoses from these specimens include urinary tract infections, strep throat and wound infections. The staff can also provide guidance on which type of antibiotic to use with some diagnoses.
  • Hematology – Encompassing the areas of coagulation and urinalysis. This area assists in the diagnosis, treatment and monitoring of several types of cancers. Common tests include hemoglobin, CBC, white count, red count and more. The coagulation staff monitors the flow of the blood, measuring its clotting capabilities as well as monitoring current coagulation treatment, such as Coumadin (a blood thinner) therapy. In the urinalysis area, testing is used to help diagnose urinary tract infections, kidney disorders, sexually transmitted diseases, diabetes and more. Blood in the urine is also detected.
  • Histology – The body’s tissues and fluids are tested in this area. This department is often utilized to diagnose cancer, and staff often work closely with surgeons to diagnose illness while patients are still in surgery.
