Hello;Welcome to Chat Doctor Low fever can be due to many sorts of infections but the commonest is TB so to diagnose TB you can get done TB GOLD test which is the diagnostic test for TB. If that comes negative then you can rest assured that it is not fever due to TB and when the general condition is fine according to opinion of the operating surgeon then she can undergo surgery.Nowadays, Laparoscopic surgery is also available which is less invasive and the hospital stay is also short. Please do the test and consult your surgeon. Thanks
