A scientist develops a new screening for congenital hearing loss that can detect cells in the infant’s blood indicating cell necrosis in the cochlea, thus it can make use of the heel prick all newborns get to screen for other diseases. After some testing, the scientist declares that the test’s sensitivity is 95 percent and its specificity is 23 percent. If it were up to you would you recommend the use of this screening tool, and what explanation represents the best basis for that decision?
