Croup: Sensitivity and Specificity

Introduction: Note that infants with Subglottic Hemangiomas are often misdiangosed with Croup

The sensitivity and specificity of findings for Croup are listed below. See the left navigation bar to change the display.

Pre-Test Probability (Prevalence): %.	Post-Test Probability (Predictive Value): %.	Switch to display mode.
Note that calculating probabilities from more than one** finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)

Findings With Unspecified Accuracy
Finding	Result	Sensitivity	Specificity
[ + ] Edema, Subglottic		No accuracy specified.
Caution: Subglottic hemangioma can be misdiagnosed as subglottic edema Study: no study specified.
