Diagnostic Tests for Nausea

Diagnostic Test list for Nausea:

The list of diagnostic tests mentioned in various sources as used in the diagnosis of Nausea includes:

  • Physical examination
    • Check hydration status by checking skin elasticity, moisture within mouth, pulse rate and blood pressure (lying and standing)
    • Check temperature
    • Look for evidence of anemia - e.g. pale skin and conjunctiva - may suggest chronic gastritis, peptic ulcer, stomach cancer or renal failure.
    • Look for evidence of jaundice - e.g. yellows skin and sclera of eyes - may suggest gallstones that pass into common bile duct, cancer of the pancreas or acute viral hepatitis.
    • Observe for ataxia (lack of co-ordination of voluntary movement) which requires ruling out a brain hemorrhage
    • Abdominal examination for tenderness - e.g. tenderness in epigastric area (midline below ribs) may suggest peptic ulceration; tenderness over the right upper abdomen may suggest gall bladder disease.
    • Abdominal examination for mass which may suggest pregnancy, stomach cancer, pyloric or intestinal obstruction, pancreas cancer, acute cholecystitis (inflammation of the gallbladder usually due to obstruction from a gallstone), Crohn's disease, abscess around the kidneys or diverticulitis
    • Examination of the central nervous system for signs of elevated intracranial pressure, acute meningitis and abnormalities of the inner ear
  • Blood tests
    • Full blood count and ESR
    • Iron studies
    • Electrolytes and renal function (especially if persistent vomiting as renal failure can present with dyspepsia, nausea and vomiting)
    • Calcium (elevated calcium may cause nausea, vomiting and abdominal pain)
    • Fasting blood sugar
    • Liver function tests
    • Pregnancy test should be routine in women of childbearing age
    • Amylase
    • Digoxin level, if suspect digoxin toxicity
    • Helicobacter pylori serology (to test for presence of bacteria that is now accepted to cause duodenal ulcers, but does not distinguish from past or present infection)
    • Gastrin levels, if multiple peptic ulcers to help diagnose Zollinger-Ellison syndrome
    • Tumor markers including Carcinoembryonic antigen (for bowel cancer)
  • Urine tests
  • Stool tests
    • Stool sample for microscopy and culture
    • Stool occult blood test may be positive with peptic ulcer or stomach cancer
  • Radiological investigations
    • Chest X-Ray
    • Abdominal X-Ray
    • Abdominal ultrasound scan - can give information about the liver, bile ducts, pancreas, kidneys. This is the best test for gallstones.
    • CT Scan abdomen if ultrasound suggests pathology but undefined
    • HIDA scan can exclude an obstructed bile duct
    • Barium swallow and barium meal can diagnose small bowel motility disorders and obstruction of the upper gastrointestinal tract
    • Scintographic gastric -emptying studies may help to diagnose delayed gastric emptying e.g. in diabetes
    • ERCP, if jaundiced, which provides information about the bile ducts
    • Intravenous pyelogram (IVP) may suggest a perinephric abscess (abscess around the kidneys)
    • CT scan of brain to rule out brain tumor, brain hemorrhage
    • Angiography is useful to diagnose mesenteric artery ischemia
  • Urea breath test - test of choice for following the response to treatment of Helicobacter pylori.
  • Upper gastrointestinal endoscopy (with biopsy of mass if found and for Helicobacter pylori) - may be required to diagnose peptic ulcers, stomach cancer.
  • Endoscopic Retrograde Cholangiopancreatography (ERCP), if jaundiced
  • Arterial blood gases (ABGs)
  • Electrocardiograph (ECG)
