The Madison Valley Medical Center Laboratory is ready and well equipped to serve you. We are here from Monday through Friday 8:00 am to 5:00 pm to provide outpatient diagnostic laboratory testing for all people, regardless of where their healthcare provider’s office is located.

We are able to provide laboratory testing with a written or faxed order from any licensed caregiver. The order must include the test to be performed, the diagnosis for the tests and the contact information from the health care practitioner, so the completed results can be delivered to them. Most routine laboratory tests are done at Madison Valley Medical Center allowing for timely results. Our experienced and well qualified laboratory staff provides testing for all patients in the hospital and the ER around the clock.

Some of the services we offer:

  • Common Laboratory tests performed on site all others available through a variety of reference labs.
  • Therapeutic Phlebotomy
  • Test performed for out of town Health Care Providers.
  • Results are faxed to appropriate providers.
  • Premarital testing
  • Paternity sample collection
  • Chain of custody Urine Drug collection and Alcohol Screening
  • Insurance physical blood drawing
  • Blue Cross Blue Shield Member facility
  • Medicare and State Licensed

Laboratory Tests

Sodium and Chloride

are electrolytes controlled by the kidneys and adrenal glands. They are important to the functioning of nerves, muscles, and most cells as well as being vital in the salt and water balance of the body.


is an electrolyte important for the proper functioning of nerves and muscles, especially the heart. Potassium levels are controlled by the kidneys. Abnormal values, whether high or low, require medical evaluation. This is especially important to monitor if you are taking diuretics or heart medication.


is a mineral which is an activator for a number of energy systems such as those regulating metabolism of carbohydrates and proteins. Abnormal levels may be found with dietary insufficiency or disease states involving kidney, pancreas, or intestine. It is also important in the normal function of the heart.


Every cell in the body uses glucose, a blood sugar, for energy. Values of greater than 140 in a fasting patient or greater than 200 in a non-fasting requiring further evaluation by a physician. This may be an indication of diabetes.

BUN - Blood Urea Nitrogen

is a waste product excreted by the kidney. High levels may mean poor kidney function. A high protein diet or strenuous exercise may also raise this level.


is a waste product excreted by the kidneys which is not affected by diet or exercise. High levels may indicate poor kidney function, while low levels are not of medical significance.

Calcium and Phosphorus

The kidneys and parathyroid gland control these minerals, which are found mostly in bone. These minerals are important for normal cellular activity.

Uric Acid

is a waste product excreted in the urine. Elevated levels may be seen with arthritis, gout, and kidney problems. Low levels are not medically significant.

Total Protein and Albumin

are normal proteins in the blood. They are an indicator of general health. Albumin attaches to and carries many substances, including medications, to different areas of the body.

Total Bilirubin

is a by-product of red blood cell destruction and is the pigment in bile. Bilirubin is processed by the liver. High serum values may be an indication of liver disease.

Direct Bilirubin

is formed in the liver and excreted in the bile. Since very little of this form is present in the blood even slightly elevated levels can indicate liver cell problems.

Alkaline Phosphatase and Gamma GT

are enzymes found in both the liver and bone. High levels of these enzymes may indicate liver or bone disease. Low levels are not significant.


are enzymes found in heart, muscle, and liver. Damage or disease of heart, muscles, or liver may result in elevated levels of these enzymes. As seen with Gamma GT, use of alcohol or medication may also increase SGOT and SGPT.


is an enzyme found in all the body’s cells. Elevated levels indicate cellular damage.


is a mineral used in making red blood cells. Iron levels are influenced by many factors, including diet and the time of day the blood is drawn. Both high and low levels of iron may indicate a disease state.


a blood fat affected by what you have recently eaten. Fasting for 12 hours prior to testing is necessary for proper evaluation.

Total Cholesterol

is a blood fat necessary for normal vitamin absorption and hormone synthesis. Elevated levels may be associated with the risk of heart disease and should be evaluated by your care provider.

LDL (Low Density Lipoprotein)

60-70% of total cholesterol is LDL. Elevated levels of LDL, the “BAD” cholesterol, are associated with an increased risk of Coronary Heart Disease. In combination with other risk factors is thought to be the most accurate predictor of Coronary Heart Disease risk. LDL can only be determined accurately when you have fasted for 12 hours and your Triglycerides are less than 400 mg/dl.

HDL (High Density Lipoprotein)

20-30% of total cholesterol is the “Good” cholesterol. One role of HDL is to carry cholesterol away from your arteries to your liver.

Cholesterol/HDL ratio

This is a calculation which helps to define the risk category you have for Coronary Heart Disease. The Ranges are as follows:

Risk Ratio Men Ratio Women
Lowest < 3.8 <2.9
Low 3.9-4.7 3.0-3.6
Moderate 4.8-5.9 3.7-4.6
High 6.0-6.99 4.7-5.6
Highest > 7 >5.7


A hormone produced and secreted by the pituitary gland which regulates the amount of thyroid hormone in the body. If the TSH level is elevated the thyroid level is low. If the TSH level is low the thyroid level is high. There is a large variability of the normal level of TSH.


Complete Blood Count - This test includes the following information below about the cells in your blood.


(White Blood Count) Number of white blood cells in thousands. White blood cells are our body’s defenders against infection. These include granulocytes and lymphocytes.


(Red Blood Cells) - Number of red blood cells in millions. Red blood cells carry oxygen to all the cells of the body.


(Hemoglobin) - The substance found in RBC’s that attaches oxygen to the red blood cells so that it can be carried to all the cells of the body.


(Hematocrit) - Tells what percentage of your total blood volume is red blood cells.


(Mean Corpuscular Volume) - indicates the red blood cell size.


(Mean Corpuscular Hemoglobin) - indicates the amount of hemoglobin in each red blood cell.


(Mean Corpuscular Hemoglobin Concentration) - A ratio of MCV to MCH and indicates cell size.


(Platelets) - Are small cells that are essential elements for blood clotting.


(Red Cell Distribution Width) shows the variation in the size of the red cells.


are for bleeding patients or to monitor people on anticoagulation therapy, like Coumadin and Heparin.


is a Thyroid Stimulating Hormone which is testing the body’s thyroid cycle in the endocrine system.


is a prostate specific antigen testing for rapid growth of prostate cells.


is a Comprehensive Metabolic Panel


is a Basic Metabolic Panel


is a B-Type Natriuretic Peptide that is a test for Congestive Heart Failure


will be drawn 5.5 - 6 hours after last dose

Hepatic Panel

is a Liver function panel

Renal Panel

is for Kidney function panel
