in this why should the answer not be biopsy of granuloma as most useful investigation is asked and ANA is positive in many other cases?
We are suspecting wegners na? So anca!
I wuld do biopsy for sure…ANCA defenitely useful…but better is biopsy
sir in this most useful investigation is asked so investigation of choice should be the answer that is biopsy?
sir i think the word most useful is making a bit confusion anca positivity and biopsy both r useful and important in their own way in diagnosis
Isn’t biopsy the ultimatum be most useful
