1. CBC (possible anemia, leukocytosis, accelerated erythrocyte sedimentation rate in gastric ulcer, duodenal ulcer, ulcerative colitis, and others.);
2. electrolytes, urea, creatinine (studied for the diagnosis of kidney function and assessment of water and electrolyte imbalance);
3. biochemical parameters of liver function: ALT (alanine aminotransferase), AST (aspartate aminotransferase), gamma - glutamyl, total protein levels in the blood, blood albumin, bilirubin);
4. Blood glucose (normal values ​​3,3 5,5 mmol / L increase in glucose level indicates the probability of diabetes);
5. biochemical parameters pancreatic alpha-amylase enzyme, a lipase enzyme;
6. antibodies to Helicobacter pylori (for the detection of gastric ulcer associated with H. pylori infection);
7. The analysis of feces for the diagnosis of digestive diseases estimated amount, texture and shape, color, smell, impurities, presence of mucus, pH;at a chemical level determined blood levels of bilirubin, stercobilin protein;
8. The study of intestinal microflora is performed in the diagnosis of intestinal dysbiosis.
