Flu Shot and TB test taken 7 days apart okay?

I had a flu shot yesterday (11/13) for work and am scheduled to take a TB test on 11/20 as part of my pre-nursing physical. Will the flu shot alter the result of the TB test? I noticed a phrase on the school's physical form that mentioned not to take the TB test within 6 weeks of a vericella vaccine and so am concerned that I should reschedule. (I realize that a flu shot and the vericella aren't the same thing, but still the question arose.)

Thank you for your help!

I don't know if the TB test will come out messed up because of the flu shot, but I would go ahead and do it anyways unless your doctor/NP/whoever tells you not to. You'll know in 2 days if the test is normal (for the PPD skin test anyways) and if it's messed up then you can wait a bit to redo the TB test. I would hazard a guess that the only reason they tell you not to do varicella at the same time is because the vaccine can give some people a few lesions that may look like the blister shown in a positive TB skin test. Just my :twocents:. Good luck!

That makes sense. I will confirm with the nurse then when she gives me the test. Thank you!

You're welcome! I'm going through the same thing right now trying to get all my immunizations in order to start school in January and I know how stressful it can be!

It might specifiy varicella because varicella is a live (attenuated) virus. The flu shot is not a live virus. If it didn't specify flu shot, I wouldn't worry.
