Yes: It is called PPD for TB testing and there is no known contraindication for getting one unless you were tested positive before.

PPD: Purified protein derivative which are TB proteins which, if you have a previous exposure to TB will cause a reaction called a "wheel." Your baby in utero will be safe as the proteins will stay right where they put them and not cross the placenta.
