The molecular heterogeneity of calcitonin is one factor that might affect the results of laboratory tests. Measurements of serum calcitonin concentration can vary widely because different assays ...

In individuals with sporadic C-cell disease, the predictive power of raised calcitonin levels to identify occult medullary thyroid cancer increases when sex-specific calcitonin thresholds are used as ...

Basal serum calcitonin levels were measured by chemiluminescence and the upper limit of the normal range was defined as 10 ng/l. Patients with basal levels ≤10 ng/l were considered to have a negative ...

Medullary thyroid carcinoma (MTC) in MEN2B syndrome is associated with germline RET mutation. Patients harboring de novo mutations are usually diagnosed at more advanced disease stages. We present a ...

Made up of a protein structure containing 116 amino acids, procalcitonin acts as a substrate for production of calcitonin – a hormone responsible for producing C-cells of the thyroid gland and ...
