Parathyroid Hormone, Fine-Needle Aspiration Biopsy (FNAB)-Needle Wash
An adjunct to cytology examination of fine-needle aspiration specimens to confirm or exclude presence of parathyroid tissue in the biopsied area
Measurement of parathyroid hormone (PTH) in fine-needle aspiration biopsies (FNAB) washings could be used to discriminate thyroid tissues from enlarged parathyroid glands and also to facilitate parathyroid localization prior to surgery.
This test is best used as an adjunct to cytology examination to confirm or exclude the presence of parathyroid tissue in the biopsied area.
PTH values of 100 pg/mL and above are suggestive of the presence PTH-secreting tissue at the site biopsied or along the needle track.
