The Genova Lab Comprehensive Digestive Stool Analysis and Parasitology provides diagnostic tools for analysis of digestion, colonic environment and absorption. Together with all the analysis of the CDSA this stool test evaluates for presence of parasites and levels of beneficial flora, imbalanced flora, pathogenic bacteria, and yeast. Well suited for people with abdominal pain, chronic diarrhea, and other GI-related symptoms.

The increase in worldwide travel, coupled with increasing immigration into the United States, contributes to the spread and incidence of parasitic infections. In addition, parasitic infections are commonly transmitted through fecally contaminated food, water, or other materials within this country. There is an increasing awareness of the important relationship between parasitic infection and a broad spectrum of illnesses and diseases.

Genova Lab comprehensive parasitology profile uses the most technologically advanced stool test procedures to accurately identify a wide range of protozoal parasites, including amoebae, flagellates, ciliates, coccidia and microsporidia. Specimens are carefully analyzed by highly trained technicians using computer-enhanced video microscopy, new staining procedures, and advanced immunoassay techniques.

Stool test for parasites and intestinal bacteria and yeast. Also evaluates digestion and the absorption of the colon environment.

Some of the Genova Lab CDSA markers:

Digestion

Common potential pathogens:

    • Aeromonas
    • Bacillus cereus
    • Campylobacter
    • Citrobacter
    • Klebsiella
    • Proteus
    • Pseudomonas
    • Salmonella
    • Shigella
    • Staphylococcus aureus
    • Vibrio
  • Triglycerides: Triglycerides are the major dietary fat component. Elevated fecal amounts reflect incomplete fat hydrolysis and suggest pancreatic insufficiency.
  • Chymotrypsin: Fecal chymotrypsin is a sensitive, specific measure of proteolytic enzyme activity.

    Decreased values suggest diminished pancreatic output (pancreatic insufficiency), hypoacidity of the stomach or cystic fibrosis. Elevated chymotrypsin values suggest rapid transit time, or less likely, a large output of chymotrypsin from the pancreas.

  • Iso-butyrate, iso-valerate and n-valerate: New research suggests that these short chain fatty acids can be produced through bacterial fermentation of protein, thus reflecting the presence of undigested protein in the bowel.

    In a healthy colon, these SCFAs constitute less than 10 percent of the total concentrations of SCFAs due to the sparse amounts of polypeptides present in the large intestine compared to indigestible carbohydrates. However, an increase in the load of protein in the colon will alter these concentrations. Causes may include pancreatic insufficiency (insufficient proteases), malabsorption or gastrointestinal disease, leading to mucosal desquamation.

Absorption

  • Long Chain Fatty Acids: These free fatty acids are readily absorbed by healthy mucosa. In cases of malabsorption, however, they accumulate and reach substantially elevated levels in the feces. They can also indicate pancreatic insufficiency.
  • Cholesterol: Fecal cholesterol comes from both dietary sources and mucosal epithelial cell breakdown. Some of this cholesterol is absorbed, stored and used by the body, but some is excreted. The fecal cholesterol level remains surprisingly constant during fluctuating exogenous intake. An elevated cholesterol level in feces is abnormal and may reflect mucosal malabsorption.

Common imbalanced flora:

  • Beta hemolytic strep
  • Enterobacter
  • Hafnia alvei
  • Hemolytic E. coli
  • Mucoid E. coli
  • Total Fecal Fat: This parameter is the sum of all the lipids except SCFAs. It can be indicative of maldigestion or malabsorption. It has been suggested that elevated long chain fatty acid levels reflect malabsorption, and elevated triglyceride levels reflect maldigestion.
  • Total Short Chain Fatty Acids: A special property of colonic bacteria is their fermentation of soluble fibers to short chain fatty acids (acetate, propionate, butyrate and valerate).66 These molecules normally are readily absorbed so that fecal levels reflect a balance between production and absorption. SCFAs provide up to 70 percent of the energy for colonic epithelial cells.56 SCFA production may be an important factor in establishing and maintaining a balanced ecosystem in the colon and may prevent establishment of pathogenic microbes such as Salmonella and Shigella species.

One interesting report suggests that diversion colitis might be successfully treated with rectal irrigations of SCFAs, specifically butyrate.67 Elevated levels of the four main SCFAs may reflect colonic malabsorption or bacterial overgrowth. Elevated levels are also found in active colitis.68 Decreased levels may reflect insufficient dietary fiber or disruption of the normal colonic flora.

Colonic Environment

Microbiology

    • Beneficial bacteria:
      Healthy amounts of Lactobacilli, Bifidobacteria, and E. coli are essential to the maintenance of a healthy system. Lactobacilli and Bifidobacteria species, in particular, have long been noted for their contributions to intestinal health from the inhibition of gut pathogens and carcinogens, control of intestinal pH and the reduction of cholesterol tothe synthesis of vitamins and disaccharidase enzymes.

      In a healthy gut, these organisms make up a substantial portion of the 400 plus species of bacteria. Bifidobacteria alone comprises up to one-quarter of the total flora in a healthy adult. Reduced numbers of these organisms, resulting from the use of broadspectrum antibiotics, chronic maldigestion or bacterial overgrowth, leave the intestine susceptible to invasion by pathogens and production of carcinogens. Measurement of their levels may indicate the need to supplement with friendly bacteria to restore these important properties. While E. coli do not share some of these direct beneficial effects, clinical observation suggests ample amounts of these organisms are present in healthy intestines.
  • Additional bacteria:
    Bacteriology cultures quantitate normal flora (Lactobacilli, Bifidobacteria, E. coli and other frequently isolated organisms), imbalanced flora and potential pathogens. Sero-typing for toxigenic E. coli and Campylobacter cultures is performed on diarrhetic specimens.
