My 80 year old step mom has been diagnosed with tb. The family was all together last saturday with her, should we all be tested? She was diagnosed on jan 17 with bronchitis, not getting better went to dr on jan 20 and told she had double pneumonia. Jan 25

If . If your family has contact with your step mother with no respiratory protection and she has active, untreated tb, you should be evaluated.
You . You must. It is a simple test that would give you answers and treatment if needed. It may not show up in week so may need to retest in future. If y'all have been around her while then should be accurate.
