Webmay be considered as cutoff point. If a subject’s test value observes less than this cutoff then may be considered as non-diseased or normal and if value measures greater than cutoff value then considered diseased or non-normal. Alternatively, the upper limit, mean+2SD of the 95% confidence interval also may be considered as cutoff value.
