| * The page name should be '''"Diagnostic study of choice for [disease name]"''', with only the first letter of the title capitalized. Note that the page is called "Diagnostic study of choice."
| | Diagnostic study of choice for diagnosing portal hypertension is to measure Hepatic venous pressure gradient (HVPG). HVPG measurement is the difference between [[Hepatic vein|hepatic venous]] [[wedge pressure]] (HVWP) and free [[Hepatic vein|hepatic venous]] pressure (FHVP). HVPG reflects the intra-[[sinusoidal]] [[pressure]]. HVPG is measured through insertion of a [[catheter]] in right [[internal jugular vein]]. |
| * '''Goal:'''
| |
| **To describe the most efficient/sensitive/specific test that is utilized for diagnosis of [disease name].
| |
| **To describe the gold standard test for the diagnosis of [disease name].
| |
| **To describe the diagnostic criteria, which may be based on clinical findings, physical exam signs, pathological findings, lab findings, findings on imaging, or even findings that exclude other diseases.
| |
| * As with all microchapter pages linking to the main page, at the top of the edit box put <nowiki>{{CMG}}</nowiki>, your name template, and the microchapter navigation template you created at the beginning.
| |
| * Remember to create links within WikiDoc by placing <nowiki>[[square brackets]]</nowiki> around key words which you want to link to other pages. Make sure you makes your links as specific as possible. For example, if a sentence contained the phrase anterior spinal artery syndrome, the link should be to [[anterior spinal artery syndrome]] not [[anterior]] or [[artery]] or [[syndrome]]. For more information on how to create links, click [[here]].
| |
| * Remember to follow the same format and capitalization of letters as outlined in the template below.
| |
| * You should include the name of the disease in the first sentence of every subsection.

| |
| * There is no single diagnostic study of choice for the diagnosis of [disease name].
| |
| * There is no single diagnostic study of choice for the diagnosis of [disease name], but [disease name] can be diagnosed based on [name of the investigation 1] and [name of the investigation 2].
| |

| The [name of investigation] should be performed when:
| | [[Category:Hepatology]] |
| * The patient presented with symptoms/signs 1, 2, and 3 as the first step of diagnosis.
| | [[Category:Disease]] |
| * A positive [test] is detected in the patient, to confirm the diagnosis.

| === 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.
| |
| *To view an example (endocarditis diagnostic criteria), click [[Endocarditis diagnosis|here]]
| |
| *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].
