TB testing

Hi all

My wifes visa application is ongoing, the caseworker dealing with our case contacted us yesterday asking for our TB test, as the test we provided was from her work not from an approved test center, got requested to looked at the government site for approved testing centers and I noticed that her country Lebanon is not on the list that requires testing? She has never left her country, so therefore I feel she doesn't need a TB test I've got her to email this back to them hopefully this is ok?

Any advice?
