* Investigations:
** Among patients who present with clinical signs of [disease name], the [investigation name] is the most specific test for the diagnosis.
** Among patients who present with clinical signs of [disease name], the [investigation name] is the most sensitive test for diagnosis.
** Among patients who present with clinical signs of [disease name], the [investigation name] is the most efficient test for diagnosis.

===== Diagnostic results =====
The following result of [investigation name] is confirmatory of [disease name]:
* Result 1
* Result 2
 
===== Sequence of Diagnostic Studies =====
The [name of investigation] should be performed when:
* The patient presented with symptoms/signs 1, 2, and 3 as the first step of diagnosis.
* 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 the 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].

Overview

Bronchoalveolar lavage (BAL) is the diagnostic study of choice for eosinophilic pneumonia. Eosinophilic pneumonia

Diagnostic Study of Choice

Bronchoscopy with bronchoalveolar lavage

  • Bronchoalveolar lavage (BAL) is performed in the majority of patients to exclude infection, hemorrhage, or malignancy.[1]
  • The BAL is performed using a sequential instillation and recovery of 50 to 60 mL aliquots in an area of radiographic opacity.
  • In acute pneumonia, the BAL fluid typically shows a very high proportion (>25 percent) and total number of eosinophils.[2]
  • The median BAL cellularity was 350,000/mm3. BAL eosinophilia was present in all cases with a median of 38%.
  • The proportion of BAL lymphocytes is approximately 10 to 30 percent and the proportion of BAL neutrophils is 1 to 16 percent.
  • The level of eosinophilia returns to normal when the illness resolves.
