PTH-Intact Tiss FNA-mCnc

Definition

Parathyroid hormone (PTH) analysis in rinsed material obtained from fine-needle aspiration biopsy (FNAB) helps to discriminate thyroid tissues from enlarged parathyroid glands and also facilitates parathyroid localization prior to surgery. Various groups have reported on the utility of this technique with specificity of 91% to 100% and sensitivity of 91% to 100%. Measuring PTH in the rinse material proved very useful in cases of non-diagnostic cytology. Comparing the results of the PTH rinse material with serum PTH is highly recommended. An elevated PTH in the serum could falsely elevate PTH in the washings if the rinse is contaminated with blood. In these cases, only PTH values significantly higher than the serum should be considered as true positives.
