Overview

Diagnostic tests provided include throat culture and checking for rapid antigen detection. Although the sensitivity and specificity of rapid antigen detection testing have improved dramatically, a throat culture is considered the diagnostic standard. It is possible to use the adjusted Centor score to help doctors determine which patients do not need testing, throat culture/rapid antigen detection testing, or empirical antibiotic therapy.

Diagnostic Study of Choice

Study of choice

The diagnostic study of choice for bacterial pharyngitis is the throat culture. A single-swab throat culture is 90 to 95 percent sensitive with proper sampling and plating techniques.[1] [2]


The comparison of various diagnostic studies for bacterial pharyngitis

Test Sensitivity Specificity
Test 1 ...% ...%
Test 2 ...% ...%

[Name of test with higher sensitivity and specificity] is the preferred investigation based on the sensitivity and specificity

Diagnostic results

The following finding(s) on performing [investigation name] is(are) confirmatory for [disease name]:

  • [Finding 1]
  • [Finding 2]
Sequence of Diagnostic Studies

The [name of investigation] must 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.

OR

The various investigations must be performed in the following order:

  • [Initial investigation]
  • [2nd investigation]

Name of Diagnostic Criteria

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.

[Disease name] is primarily diagnosed based on clinical presentation. There are no established criteria for the diagnosis of [disease name].

OR

There is no single diagnostic study of choice for [disease name], though [disease name] may be diagnosed based on [name of criteria] established by [...].

OR

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].

OR

The diagnosis of [disease name] is based on the [criteria name] criteria, which includes [criterion 1], [criterion 2], and [criterion 3].

OR

[Disease name] may be diagnosed at any time if one or more of the following criteria are met:

  • Criteria 1
  • Criteria 2
  • Criteria 3

OR

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].

OR

The diagnosis of [disease name] is based on the [criteria name] criteria, which include [criterion 1], [criterion 2], and [criterion 3].

OR

The diagnosis of [disease name] is based on the [definition name] definition, which includes [criterion 1], [criterion 2], and [criterion 3].

OR

IF there are no established diagnostic criteria

There are no established criteria for the diagnosis of [disease name].
