I just wondered if anyone has some really good website where the issues sensitivity /specificity are addressed. We use these words so much today, but I constantly forget which one means what. I think ( based upon just rememberance ) that sensitivity is how sensitive a test is to confirm that someone has the problem… but I might be incorrect.

I just wanted to get some "sensitivity /specificity for dummies" to help me remember those issues once and for all.

Here is a good one from Josh Cleland


Sensitivity:  SnNout A test with high sensitivity and a negative result is good for ruling out a disorder


Specificity: SpPin:  Test with high specificity and a positive result is good for ruling in a disorder


SpPin and SnNout  easy as that!

Sensitivity is how well the test is at finding a positive result.  (how likely it is to find a problem)

Specificity is how well it is at finding a negative result.  (how likely it is to rule out a problem)


For instance, in 2005 an article by Park stated that the drop arm test (when testing for rotator cuff integrity) is 35% sensitive and 88% specific.  So you can read it as having a 35% chance of finding a RCT by performing the test and getting a positive result.  On the other hand, if you have a negative test, there is a 88% liklihood that there is no RCT.


Wikipedia actually does a decent job explaining this as well.…..pecificity
