I had a 2 part series tb test done, came back negative. that was back around 1/26/22. now for a new job another tb test needs to be done. is it save to have another tb test? it's just a poke to the arm?

Yes, it is safe to repeat the test. If you had a skin test, you could use the results, verified by your doctor and present those to the new organization. A blood test can be used instead to the usual skin test.

Inquire as to whether they can accept the prior result for their records. If you have had possible interim exposure to TB, a re testis suggested.
