Lymphomatoid granulomatosis: Sensitivity and Specificity

Introduction: None written.

The sensitivity and specificity of findings for Lymphomatoid granulomatosis 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
[ + ] Leukopenia		No accuracy specified.
Leukopenia is NOT a feature of WG. A Leukocyte count < 4000/mm3 can be seen in patients with lymphomatoid granulomatosis which evolves into lymphoma. It is often confused with WG.
