Even if a test accurately and efficiently identifies people with pre-clinical disease, its effectiveness is ultimately measured by its ability to reduce morbidity and mortality of the disease. The most definitive measure of efficacy is the difference in cause-specific mortality between those diagnosed by screening versus those diagnosed by symptoms. There are several study designs which can potentially be used to evaluate the efficacy of screening. illustrates the yield if the screening program were conducted in female blood donors, in whom the prevalence of disease is only 0.01%. Even with 100% sensitivity and 95% specificity, the positive predictive value is only 1.9%.

Abnormal test results might suggest that you’re at risk of bleeding or developing clots in your blood vessels. A lipoprotein panel measures the levels of LDL and HDL cholesterol and triglycerides in your blood. Abnormal cholesterol and triglyceride levels may be signs of increased risk for CHD.

The unscreened population will include an assortment of subjects with long and short DPCPs, and they will all be identified by their symptoms and/or death. The screened subjects who are identified as having disease will tend to have longer survival times, because they have, on average, a less aggressive form of cancer.
