Algorithm Type: 
Case, Control
Implementation Details: 

Cases: We reviewed 50 patients. We had 2 false positives for a PPV of 96%. 

Controls: We reviewed 50 patients.  We had 9 false positive for a PPV of 82%. 

Subtyping: We also reviewed 30 Atopic and 30 non atopic subtyped cases. We had one false positive for an Atopic PPV of 97%. We had only 3 true positives and 27 false positives for the non atopic cases. PPV was 10%.
