WebbAfter cancer treatment, there should be very low levels of thyroglobulin in the blood since the goal of treatment is to remove all thyroid cells. If Tg is rising after surgery and/or radioactive iodine, it may be a sign of more cancer. A tumor marker test may be done to measure the body’s Tg level before, during, and/or after treatment.

WebbTgAb is detected in approximately 20% of DTC patients and may be a more specific thyroid tumor marker than thyroid peroxidase antibodies. TgAb interferes with Tg immunometric assay (IMA) measurements, causing falsely low/undetectable Tg values, especially when TgAb concentrations are high and serum Tg concentrations (measured by RIA) are low.
WebbThyroglobulin measurements in tissue and serum play an integral role in the evaluation of patients who have thyroid cancer. Immunohistochemical detection of thyroglobulin in surgical specimens is useful in the differential diagnosis of tumors of unknown origin; however, the most important application of thyroglobulin measurement in clinical … WebbIn athyrotic patients, thyroglobulin is an excellent tumor marker because it is produced exclusively by the follicular cells of the thyroid. However, thyroglobulin measurement is not recommended for the screening or initial diagnosis of thyroid cancer due to the significant overlap between the levels in benign thyroid diseases and those in thyroid cancer patients.

WebbAs a tumor marker, Tg lacks specificity since it could be up‐regulated in benign thyroid diseases, and as such should not be used in the initial diagnosis of thyroid cancer. The presence of the TgAb in up to 30% of thyroid cancer patients is problematic as they interfere in Tg immunometric assays. laktat alkaloseWebbNavigating the complexities of Medicare policies can be complicated, but Quest is here to help.

Thyroglobulin (Tg) is a thyroid-specific glycoprotein (approximately 660 KDa) that serves as the source for thyroxine (T4) and triiodothyronine (T3) production within the lumen of thyroid follicles. For T4 and T3 release, Tg is reabsorbed into thyrocytes and proteolytically degraded, liberating T4 and T3 for secretion. assa ikon
