Comprehensive Digestive Stool Analysis (CDSA) Level 4+ by i-Screen

Most comprehensive stool assessment for digestive, absorption, metabolic, inflammation, and tumour/ulcer markers.

Additional Information

This CDSA Level 4+ stool test analyzes various aspects of digestive health, including macroscopic features (stool color, form, mucous, blood), microscopic components (pH, blood cells, food remnants, fibers, fat globules, starch), digestive and absorption markers (short-chain fatty acids, pancreatic elastase, long-chain fatty acids), metabolic markers (β-glucuronidase, beneficial short-chain fatty acids), inflammation markers (fecal calprotectin, fecal secretory IgA, α-transglutaminase IgA), and tumour/ulcer markers (M2 pyruvate kinase, H. pylori antigen). It's beneficial for individuals experiencing gut-related symptoms like IBS, indigestion, dysbiosis, constipation, and diarrhea.

Biomarkers Tested (69)

Stool Colour

Brown is normal; other colors may indicate abnormal gastrointestinal conditions.

Stool Form

Variations may indicate abnormal gastrointestinal conditions.

Mucous

Mucous production may indicate infection, inflammation, or malignancy.

Faecal Occult Blood

Detects bleeding in the digestive tract, indicating potential disease.

Imbalances in gut pH influence short-chain fatty acid production and their effects.

Red blood cells

Presence may indicate infection, inflammation, or hemorrhage.

White blood cells

Presence may indicate infection, inflammation, or hemorrhage.

Food remnants

Presence may indicate maldigestion.

Meat fibres

Presence may indicate maldigestion from too little gastric acid or reduced pancreatic output.

Vegetable fibres

Presence may indicate maldigestion from gastric hypoacidity or diminished pancreatic output.

Fat globules

Elevated levels may indicate inadequate lipid absorption (steatorrhea).

Starch

Presence may indicate carbohydrate maldigestion.

Short Chain Fatty Acids, Putrefactive

Produced when anaerobic bacteria ferment undigested protein, indicating protein maldigestion.

Pancreatic Elastase (µg/g)

Assesses pancreatic exocrine function; levels reflect the activity of trypsin, chymotrypsin, amylase, and lipase.

Long Chain Fatty Acids

Elevated levels may indicate inadequate lipid absorption.

β-Glucuronidase

Enzyme that breaks down the bond between glucuronic acid and toxins; indicates potential toxin reabsorption.

Short Chain Fatty Acids, Beneficial

Produced by gut bacteria; numerous benefits for gut health.

Butyrate

Decreased levels may indicate inadequate colonic function.

Acetate

Decreased levels may indicate inadequate colonic function.

Propionate

Decreased levels may indicate inadequate colonic function.

Valerate

Plays important roles in maintaining gut health and overall well-being.

Faecal Calprotectin (µg/g)

This protein is released into the stool when the intestinal lining is damaged. It's usually very high in cases of Inflammatory Bowel Disease (such as Crohn's or ulcerative colitis), and low in IBS. Calprotectin is also elevated with gut infections and colon cancers.

Faecal Secretory IgA

Secreted by mucosal tissue; represents the first line of defense of the GI mucosa.

α-Transglutaminase IgA

Most sensitive and specific gluten intolerance test for celiac disease.

M2 Pyruvate Kinase

Key regulator of tumor metabolism; may assist in identifying gastrointestinal tumors.

H.Pylori antigen

Indicates presence of current H. pylori infection.

Bifidobacteria longum
