°  Sample required: 1 vial with stool sample
°  Lab reporting time: 3 - 5 business days

Overview
Each stool analysis determines the presence of a particular parasite or bacteria antigen, using antibody to antigen on stool. A positive result always indicates active infection.

Physiology
The presence of any of the above parasites or bacteria can produce anatomic disruption of the intestinal mucosa resulting from the physical infestation of the microorganism, and chemical insult and physiological upset of the mucosa caused by adverse reactions to the metabolic products of the invader. Maldigestion and malabsorption causing nutrient and water deprivation can produce long-term dysfunction of the host. The insidious nature of this condition is marked by the observation that it can persist subclinically for years, even decades. By the time signs and symptoms become evident, the patient might be suffering severe and extensive underlying pathophysiology.

Even more ominous than a primary infestation is the tendency of invading microorganisms to metamorphosize into various stages, and to migrate to tissues and organs sometimes distant from the gastrointestinal tract. Such stages, including cysts, can remain dormant within tissues, and can be extremely difficult to detect. Discouragingly, the level of difficulty of detection is often directly proportional to the level of difficulty of treatment. These factors underscore the importance of maintaining constant vigilance in controlling the intestinal environment.

Clinical Aspects
Optimal GI health is a prerequisite for most body physiology. The functions of digestion and absorption are so fundamental to the maintenance of homeostasis in metabolism that every physiological process is ultimately dependent upon the gastrointestinal system. Suboptimal GI function can be either a basic cause of or a substantial contributor to a variety of disorders, some of which may have seemingly little or no obvious clinical correlation to GI physiology.

Conditions Assessed
Conditions that may be assessed include suspected parasitic or bacterial infection, maldigestion, malabsorption and pathologies caused by infectious agents.

Logical Sequence of Testing
The logical sequence of using this test as an initial or as a follow-up test is determined by a variety of individual considerations, including the patient's chief complaint, the array of signs and symptoms, the chronicity of the condition, the tests previously taken, and the judgment of the practitioner.
