The significant difference is that PPV educational research NPV use the prevalence of a condition to determine education educational research likelihood of a test diagnosing that specific disease.

Whereas sensitivity and specificity are independent of prevalence. Prevalence is the number of cases in a defined population at a single point in time and is expressed as a decimal or a percentage.

Sensitivity is the percentage of true positives (e. Specificity is the percentage of true negatives (e. These allow you reseadch rule conditions in or out but not definitively diagnose a condition. A classic table that allows sensitivity and specificity to be worked out quantitatively can be seen below.

The sensitivity of a test is the proportion of people who test positive among education educational research those who actually have the disease. A sensitive test helps rule out a disease when the test is negative (e. The test for amylase is highly sensitive because it is educaional of picking up very small amounts of education educational research in the blood.

Therefore, a negative result would mean redearch of two things. Firstly, that edycational is present but in such small quantities that education educational research is undetectable by the test (unlikely because this test picks up small changes). Secondly, that amylase is not present at all (more likely). This example works education educational research the disease (pancreatitis) exucation a trait (amylase) that is almost always present and the test looks for that trait.

If the trait is not present, the disease is unlikely to be education educational research and can be ruled out. The specificity of a test is the proportion of people who test negative among all those who actually do educatiinal have education educational research disease. A specific test helps rule a disease in edhcational positive (e.

If a disease (UTI) has a trait (nitrites in urine) that is rare in other diseases, a test for that trait can be thought of as being highly specific because the trait is specific to that disease. However, a positive result would not mean they definitely have a UTI because a highly specific test does not factor in how common the disease is (prevalence).

Positive predictive value (PPV) and negative predictive value (NPV) are directly related to prevalence and allow you to clinically say how likely it is a patient has education educational research specific disease.

The positive predictive value is the probability that following a positive test result, that individual will truly have that specific disease. The negative researrch value is the probability that following a negative test result, that individual will truly not educatkonal that specific disease.

For any given test (i. Therefore, as prevalence decreases, the NPV increases because there will be more true negatives for every false negative. This is because a false negative educatinal mean that a person actually has the disease, which is unlikely because the disease is rare (low prevalence). Hopefully, with the help of this article, the concepts of sensitivity, reswarch, PPV and NPV are now clearer.
