having a positive TB blood test/false abnormal test; having a positive TB blood test/false abnormal test; This is a spontaneous report from a non-contactable consumer (patient; reported for herself) via the Pfizer sponsored program. A 37-years-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE, Solution for injection, lot number and expiry date were not reported) via an unspecified route of administration on 17Apr2021 as dose 2, single for covid-19 immunization. The patient's medical history and concomitant medications were not reported. The patient received the first dose of bnt162b2 (at the age of 37 years old (as reported)) for covid-19 immunisation on an unspecified date in 2021. Patient previously had flu vaccine for immunization in Nov2020. Patient mentioned she is a clinical lab scientist. She was calling about the Pfizer BioNtech Covid 19 Vaccine. She received her last dose 17Apr2021. Two days ago, 28Jul2021, she had a TB blood test and this blood test came back positive. She was wondering if the Covid-19 Vaccine had an impact on the TB test results. She has been tested for TB before and never had positive results before (negative on date unspecified). This was the first time. Furthermore, patient reported having a positive TB blood rest and asked if the Pfizer covid 19 vaccine has any impact on her test results. Her second dose of the vaccine was administered on 17Apr2021. This has never happened before to her, she needed this test for a job, she will have to get a chest x-ray. Patient went on to say she will call back with an update, pending her chest x-ray results, saying "she don't know maybe she was unique". She expressed disbelief that there was no additional information on this, saying "you guys don't know, really?". Patient also said that perhaps this situation should be studied and "maybe do a clinical trial on her". She later clarified event details and stated the results came back positive abnormal. She officially got the results today (28Jul2021). She stated she knew this was false abnormal test. She was making the assumption it was due to the vaccine. She stated she got the TB test due to about to start a new job. She wondered if she should get chest-x ray. She stated she was calling Pfizer to let us know this occurred and to see if this was something common out there. She stated when people have to get jobs and go through vaccinations like getting the MMR, Flu Vaccine, get TB tested, and now covid vaccine it's a lot. She further clarified she got the Flu Vaccine November of last year.  She clarified with the MMR she did a blood test and found out she did not need the vaccine. She was immune to it. She clarified she did not need the MMR vaccine. She stated she wanted to add the methodology of the way this test was conducted was chemiluminescene immune acid, it was the method for the TB test. She then questioned if she should have to worry about completing this report or if the report like this come back and bite her. She questioned if this would cause panic. The event was reported as non-serious. The outcome of the event was unknown.    No follow-up attempts are possible; information about lot/batch number cannot be obtained.
