What is health screening?
identifying apparently healthy individuals who may be at increased risk of a disease or condition; looks for diseases before symptoms appear

-Morbidity/mortality risk high
-Must be able to treat (better than reactionary)

What is sensitivity?
It is measured as the proportion of those with the condition, who have a positive test result. It is the same as the detection rate.

It is measured as the proportion without the condition, who have a negative test result
What is positive predictive value?
the probability that a patient with a positive (abnormal) test result actually has the disease.
What is negative predictive value?
probability that a person with a negative (normal) test result is truly free of disease.
What is the equation for positive predictive value?
True positives/total positives
What is the equation for negative predictive value?
True negatives / total negatives
