Overview
The two most sensitive and specific tests used in diagnosing Dumping syndrome are the Oral Glucose Provocation test and the Hydrogen Breath test.
Diagnostic Study of Choice
Study of choice:
- Oral glucose provocation test is the study of choice for the diagnosis of dumping syndrome.
The comparison table for diagnostic studies of choice for Dumping syndrome
| Sensitivity | Specificity | |
|---|---|---|
| ✔ Oral glucose provocation | 100% | 92% |
| Hydrogen breath | 100% | ? |
✔= The best test based on the feature
Diagnostic results
The following result of the oral glucose provocation test is confirmatory of dumping syndrome:
- An increase in the heart rate by 10 beats per minute or more in the first hour after an oral glucose challenge of 50 grams glucose after fasting for 10 hours.
The following result of the hydrogen breath test is confirmatory of dumping syndrome:
- A positive hydrogen breath test after glucose ingestion.
Diagnostic Criteria
- Here you should describe the details of the diagnostic criteria.
- Always mention the name of the criteria/definition you are about to list (e.g. modified Duke criteria for diagnosis of endocarditis / 3rd universal definition of MI) and cite the primary source of where this criteria/definition is found.
- Although not necessary, it is recommended that you include the criteria in a table. Make sure you always cite the source of the content and whether the table has been adapted from another source.
- Be very clear as to the number of criteria (or threshold) that needs to be met out of the total number of criteria.
- Distinguish criteria based on their nature (e.g. clinical criteria / pathological criteria/ imaging criteria) before discussing them in details.

- If relevant, add additional information that might help the reader distinguish various criteria or the evolution of criteria (e.g. original criteria vs. modified criteria).
- You may also add information about the sensitivity and specificity of the criteria, the pre-test probability, and other figures that may help the reader understand how valuable the criteria are clinically.
- [Disease name] is mainly diagnosed based on clinical presentation. There are no established criteria for the diagnosis of [disease name].
- There is no single diagnostic study of choice for [disease name], though [disease name] may be diagnosed based on [name of criteria] established by [...].
- The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met: [criterion 1], [criterion 2], [criterion 3], and [criterion 4].
- The diagnosis of [disease name] is based on the [criteria name] criteria, which includes [criterion 1], [criterion 2], and [criterion 3].
- [Disease name] may be diagnosed at any time if one or more of the following criteria are met:
- Criteria 1
- Criteria 2
- Criteria 3
IF there are clear, established diagnostic criteria:
- The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met: [criterion 1], [criterion 2], [criterion 3], and [criterion 4].
- The diagnosis of [disease name] is based on the [criteria name] criteria, which include [criterion 1], [criterion 2], and [criterion 3].
- The diagnosis of [disease name] is based on the [definition name] definition, which includes [criterion 1], [criterion 2], and [criterion 3].
IF there are no established diagnostic criteria:
- There are no established criteria for the diagnosis of [disease name].
