Is it normal to need a tuberculosis skin test?

Yes: Yes if you have high risk exposure such as being a health care worker or frequent overseas traveler.

Required of some: Public health and safety statutes in some locals require that workers in public venues like the food industry, jails, health care, etc. Show evidence that they do not have evidence of contageous illness. Though not common, the resurgence of multiply drug resistant TB in some populations has kept concern detecting this disease high. If at risk thru work or travel it is to your advantage to be screened.
