A little confused?
FLUS=follicular lesion of undetermined sig.
There have to be cells to make this diag. The usual thing is to redo the US/if nec FNA in a few months, dep on US. If there are cells a Thyroseq.v2 is very accurate for mutations. This sounds non-diagnostic. Make sure doc doing FNA is experienced. Likely need repeat. Ask for pathologist to reread. If 3rd FNA->path look immed to make sure adeq. New doc?
