Use

Parathyroid Hormone by Immunohistochemistry (IHC) is utilized for the detection and localization of parathyroid hormone in tissue samples. This can assist in the diagnosis of parathyroid-related disorders by highlighting the presence of the hormone within tissue sections, potentially indicating hyperparathyroidism or parathyroid tumors. Diagnosis through PTH IHC can guide clinical decisions regarding treatment options for thyroid and parathyroid conditions.
