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
- 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
- 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)
