The concern with the skin test is that they actually inject dead tuberculosis bacteria under your skin, along with a bunch of toxic chemicals, including phenol. So anyone who has concerns about vaccines should have concerns about the skin test.

I think that most people unfamiliar with the test are thrown off by the word "test." They probably don't think that it is an injection.
You can ask your doctor for a sputum test, where the lab cultures a sample of your sputum that you collect at home first thing in the morning. You have to do really deep coughs to get up the mucus. It is really hard if you are not sick! My throat was sore for a day after doing it. But it was totally worth avoiding the injection or a chest xray! The sputum culture takes 6 weeks before they will report a negative result, so plan ahead and do it early.
If you are pregnant or nursing, your doctor will most likely order the sputum test for you no problem. If not, you can say you are allergic to one of the components of the test, or that you have had a previous allergic reaction such as hives or trouble breathing after a TB skin test. The doctor might suggest a chest xray instead. Just say you don't want to be exposed to the radiation, which is quite high in a chest xray.
You'll probably have to go to your own doctor if you want a sputum test. I called my county's public health department, where many people go to get TB tests. They said they would not do a sputum test for me, even after I told them I was allergic to phenol. They said they would have to do a chest xray instead.
