Northwest Medical Center’s laboratory testing includes thousands of different tests that can be performed on a wide variety of specimens including blood, urine, and stool, as well as specimens from the throat, skin, and wounds, among others.
The most frequently performed tests are blood sugar (glucose), cholesterol, red and white blood cell counts, and kidney and liver tests.

The majority of tests are done on a blood specimen obtained by drawing blood from a vein in the arm. For specimens from the throat, skin, ears, etc., a cotton-tipped swab will be used to touch the area to obtain the sample. Other specimens may be obtained by collecting a stool or urine specimen in a container. Once the specimen is collected, the blood or other sample is tested using a finely-tuned laboratory instrument by a certified clinical laboratory scientist.
Many factors can affect the results of lab tests such as when you last ate or exercised, your age, and any medications you are taking. Your physician will take all these factors into consideration when interpreting your lab test results. Your physician can discuss the results with you.
A physician’s order that includes your diagnosis and the physician’s signature is required for laboratory testing.
