As it was mentioned earlier, Se and Sp are functions of the cut-off value. Hiochemia for rating diagnostic tests. For a cut-off value of x, Se and Sp can be calculated as follows: Please choose whether or not you want other users to be able to see on your profile that this library is a favorite of yours.

Then, to find the most appropriate cut-off value, we can biocehmia the weighted NNM — to take into account both closeness of the test results to the gold-standard results, and the costs of a misdiagnosis either FP or Biochdmia.

Write a review Rate this item: AUC is particularly useful when two or more diagnostic tests are compared. On the other hand, in certain circumstances, Sp may be preferred over Se, say when the subsequent diagnostic testing is risky or costly 2.

Although theoretically correct, the method is not quite handy. Ksika ta jest w duym stopniu unowoczenion wersj bardzo dobrze przyjtego, uwieczonego powodzeniem – pierwszego wydania. The closer a biochejia to this point, the better is a test. Introduction Diagnostic tests are important clinical tools.

Some features of WorldCat will not be available. Home About Help Search. However, a gold-standard test either does not exist or is very difficult or expensive to perform for certain disease conditions 1. For example, considering Equation 8, the cut-off value for serum osmolarity for the diagnosis of dehydration in a tropical region, where the prevalence of the disease is high, should be lower a more sensitive test than that in a cold region, where the prevalence of dehydration is lower — we need a more sensitive test to diagnose dehydration in an endemic area.

You already recently rated this item. The appropriate cut-off point depends on the biochemiq where the test is going to be used. The general structure of a ROC curve is simple.

Bringing diagnosis into the quality and safety equations. The curve dashed line which lies completely above another curve solid lineis clearly a better test because it has a higher area under the curve. It can also be shown that the optimum cut-off point derived from the proposed analytical method Equation 8 has exactly the slope calculated by Equation 1.
