A Full Gastroenterology Test panel comprises a group of blood and stool tests that evaluate digestive system function, detect infections, inflammation, liver and pancreatic health, and malabsorption disorders. It is commonly ordered for patients presenting with symptoms like abdominal pain, indigestion, jaundice, diarrhea, or unexplained weight loss.
Typical components include:
Liver Function Tests (LFTs) – Assess liver enzyme levels, bilirubin, and protein synthesis.
Pancreatic Enzymes – Amylase and lipase.
Complete Blood Count (CBC) – To check for anemia or infection.
Serum Electrolytes – To assess balance affected by diarrhea or vomiting.
Stool Analysis – For occult blood, parasites, and infections.
Helicobacter pylori (H. pylori) Testing – Blood antibody or stool antigen test for ulcer-causing bacteria.
Other markers such as C-reactive protein (CRP) for inflammation.
Test | Normal Range | Abnormal Findings | Clinical Significance |
|---|---|---|---|
Alanine Aminotransferase (ALT) | 7 – 56 U/L | Elevated: liver cell injury (hepatitis, fatty liver) | Liver cell damage |
Aspartate Aminotransferase (AST) | 10 – 40 U/L | Elevated: liver injury, muscle damage | Liver and muscle health |
Alkaline Phosphatase (ALP) | 44 – 147 IU/L | Elevated: bile duct obstruction, bone disease | Biliary tract function |
Total Bilirubin | 0.1 – 1.2 mg/dL | Elevated: jaundice, liver dysfunction, hemolysis | Liver excretory function |
Direct (Conjugated) Bilirubin | 0.0 – 0.3 mg/dL | Elevated: liver or bile duct disease | Obstruction or hepatocyte dysfunction |
Serum Albumin | 3.5 – 5.0 g/dL | Low: liver disease, malnutrition | Liver synthetic function |
Serum Amylase | 30 – 110 U/L | Elevated: pancreatitis | Pancreatic inflammation |
Serum Lipase | 0 – 160 U/L | Elevated: acute pancreatitis | Pancreatic inflammation |
Complete Blood Count (CBC) | Refer to CBC norms | Anemia: GI bleeding; Leukocytosis: infection/inflammation | Systemic response |
Stool Occult Blood Test | Negative | Positive: GI bleeding (ulcers, malignancy) | Gastrointestinal bleeding |
Helicobacter pylori Antibody / Stool Antigen | Negative | Positive: H. pylori infection | Peptic ulcer disease risk |
C-Reactive Protein (CRP) | < 5 mg/L | Elevated: inflammation | Inflammatory bowel disease or infection |
Serum Electrolytes (Na+, K+, Cl-) | Na: 135-145 mEq/L, K: 3.5-5.0 mEq/L, Cl: 98-106 mEq/L | Abnormal: dehydration, malabsorption | Electrolyte balance |
