 A
laboratory test is a medical procedure that involves testing a sample of
blood, urine, or other tissues or substances in the body. Such tests have
a variety of uses. They are often used as part of a routine checkup to
identify possible changes in a person's health before any symptoms occur.
Laboratory tests also play an important role in diagnosis when a person
has symptoms. In addition, tests may be used to help plan a patient's
treatment, evaluate the response to treatment, or monitor the course of
the disease over time.

The Adrenocortex Profile
by Dr. Gary Farr 7/2/2004
The Adrenocortex Stress Profile is a powerful and precise non-invasive test that evaluates levels of the body's important stress hormones, cortisol and DHEA. This profile serves as a critical tool for uncovering biochemical imbalances that can underlie anxiety, chronic fatigue, obesity, diabetes and a host of other clinical conditions. It's also a crucial tool for monitoring DHEA and/or cortisone therapy.
The Comprehensive Digestive Stool Analysis
by Dr. Gary Farr 6/25/2004
I often tell my patients that the gastrointestinal tract is much like a carburetor in a car. Your digestive tract tract must take gasoline (your food), and then mix it with air (enzymes and other digestive juices). If this mixing process goes well, your car runs and doesn't cough or sputter. How efficiently your fuel burns determines to a large extent how many years you're going to get out of your car. Although a rather crude analogy, this principle does hold true for the human digestive tract. There are many points along the digestive where some "burning" process can go awry and cause seemingly unrelated problems elsewhere in the body. This article will discuss those various places and give you a very good detail of what can go wrong.
The Comprehensive Thyroid Assessment

The Comprehensive Thyroid Assessment is a thorough analysis of thyroid hormone metabolism, including central thyroid gland regulation and activity, thyroid production and secretion, peripheral thyroid conversion, and thyroid autoimmunity. This test allows the practitioner to pinpoint common imbalances that underlie a broad spectrum of chronic illness.
The Vaginosis Profile
by Dr. Gary Farr 6/24/2004
The Vaginosis Profile from Great Smokies Diagnostic Laboratory is one of the most comprehensive evaluations available. It features microscopy for every sort of organism by trained and experienced technicians with an advanced DNA probe for the most common causes of the condition. With a rapid, semiautomated DNA probe test to definitively identify clinically significant levels of Gardnerella, and Trichomonas, detection rates for these organisms can reach levels of 90% and greater in properly transported specimens.
