What is this test?
The Gastric Fluid Acetone test measures the amount of acetone, a type of ketone body, in your stomach fluid. Acetone is produced when the body breaks down fat for energy, which typically happens when there is insufficient insulin to use glucose properly. This test helps healthcare providers evaluate your metabolic state, particularly if diabetes-related complications are suspected.
How is the test performed?
A small sample of gastric fluid is collected through either an endoscopy procedure (where a flexible tube with a camera is passed through the mouth into the stomach) or a nasogastric tube (a tube inserted through the nose into the stomach). The collected fluid is then sent to a laboratory where the acetone concentration is measured using specialized chemical analysis methods.
Why might I need this test?
Your doctor may order this test if you have symptoms of diabetic ketoacidosis (DKA), such as excessive thirst, frequent urination, nausea, vomiting, abdominal pain, confusion, or rapid breathing. It may also be used to monitor patients with poorly controlled diabetes or those at risk of developing metabolic complications. Additionally, this test can help evaluate unexplained metabolic acidosis or monitor the effectiveness of diabetes treatment.
What do the results mean?
Normal results typically show minimal or undetectable acetone in gastric fluid. Elevated levels may indicate diabetic ketoacidosis, prolonged fasting, extreme diets (such as ketogenic diet), or other conditions causing ketone body production. Your healthcare provider will interpret your results along with other clinical findings, blood tests, and your overall health condition to make an accurate diagnosis and determine appropriate treatment.
Are there any risks?
The risks associated with this test are minimal and primarily related to the sample collection method. Endoscopy may cause mild throat discomfort or rare complications like bleeding or perforation. Nasogastric tube insertion may cause minor nose or throat irritation. These procedures are generally safe when performed by trained healthcare professionals.
Reference range
Acetone is normally not detectable or present in very low concentrations (<0.5 mmol/L). Reference range may vary by laboratory methodology.N/A
No special preparation required. Inform laboratory of any medications, supplements, or recent alcohol consumption.
