Onsite Lab

The Medical Specialty Center is equipped with a fully functional lab draw station that processes numerous patient samples for a variety of diagnostic purposes every day. Laboratory testing can be extremely important in determining what is wrong (or not wrong) with an individual patient.

We offer a wide range of on-site lab tests to make it convenient for you to get the testing you need.  Common blood tests include:

  • CBC
  • Metabolic panel (blood sugar, hemoglobin A1c, liver and kidney function)
  • Lipid panel (cholesterol, triglycerides)
  • VAP cardiovascular panel and inflammatory markers
  • Thyroid testing (TSH, T4, T3, fT3, fT4, rt3, TAB, TPO)

We also offer nutritional testing, annual physical exams and PAP tests, and urinalysis.  Our laboratory is also able to conduct specialty testing.  Some examples are listed below:

  • NTX testing for bone loss - urine analysis
  • Salivary adrenal stress testing
  • Candida Antibodies (yeast overgrowth)
