Diagnostic accuracy parameters for OvGM2AP.

Cut off values were obtained at mean + 3 standard deviations of the hypoendemic serum (HES). Sensitivity refers to the probability of getting a positive test result in subjects with the disease; Specificity is the probability of a negative test result in a subject without the disease; Positive predictive value defines the probability of having the disease of interest in a positive result; Negative predictive value is the probability of not having the disease in a subject with a negative test result; Likelihood ratio for positive test results indicates how much more likely the positive test result is to occur in subjects with the disease compared to those without the disease; Likelihood ratio for negative test results represents the ratio of the probability that a negative test result will occur in subjects with the disease to the probability that the same result will occur in subjects without the disease.
