Any diagnostic biopsies (needle,endoscopic etc.) get minimum of two
levels in our lab. We have seven pathologists and their preference will
determine any variations to this. After all, they have to sign their
name to the report. We handle levels and serial sections same as you.
Only needle biopsies of breast get levels, other breast blocks do not.
Hope this helps.
