For subsequent analysis of the specimen, the needles may be rinsed into a physiologic solution, tissue culture medium, transportation medium or proprietary fixative for liquid based processing. Needles should not be re-sheathed using a two handed technique and instead should be discarded directly into an OSHA approved sharps disposal container. 9 For cystic lesions, remove as much fluid as possible. The cyst fluid can be handled as a liquid specimen. If there is a residual mass, the procedure for solid lesions as described above should be followed. Ancillary testing can be performed as indicated. See section.
