Figures & data

Table 1. Positive predictive value (PPV) and negative predictive value (NPV) of microscopic hematuria for detecting kidney cancer assuming 5% prevalence of microscopic hematuria in general population and 0.25% prevalence of undiagnosed kidney cancer in general population accounting for contribution of renal cell carcinoma and transitional cell carcinoma.

	Kidney Cancer Present	Kidney Cancer Not present	Totals	Predictive Values
Microscopic hematuria present	113	4887	5000	PPV is 2.26% (1.88, 2.71)
Microscopic hematuria not present	137	94863	95000	NPV is 99.86% (99.83, 99.88)
Total	250	99,750	100,000
