Our services range from routine blood tests — such as total cholesterol, Pap testing and white blood cell count — to complex, gene-based and molecular testing.
We also perform medical tests that aid in the diagnosis or detection of diseases, measure the progress or recovery from a disease or confirm that an individual is free from disease. We have specialized expertise in cancer, cardiovascular diseases, infectious diseases, and neurology.
