LOINC description : 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.;
