	From the above we can see that the more the curve overlap the smaller will be the area under the ROC curve (which is a diagonal when the two curves fully overlap). In such a situation it may be that the test is useless and that an alternative test needs to be developed based on different parameters.

	The cutoff value is chosen to minimize missing true positives, thus including more false positives. ( for example: when consequences of missing a case are serious, e.g. testing potential blood donors for HIV).

 A receiver operating curve (ROC) is a plot of sensitivity versus 1-specificity. The name is derived from its original use in radar technology. The dotted line shown in the ROC curve represents a useless test that has no discriminatory power. The size of the area between the dotted line and the solid line in the ROC curve reflects the ability of a test to discriminate between diseased and non-diseased individuals across the range of potential cut-offs.
