Tg Antibodies Rising

This is information I compiled related to questions concerning Thyroglobulin Antibodies (TgAb)remaining elevated or increasing following total thyroidectomy despite having low or undetectableThyroglobulin (Tg) and whether TgAb can be used to detect recurrence of thyroid cancer. Elevated Thyroglobulin Antibodies (TgAb) in the absence of elevated Tg levels Thyroglobulin is uniquely produced by thyroid follicular cells.Biotin… Continue reading Tg Antibodies Rising

Falsely Elevated Thyroglobulin – HAMA

Serum Thyroglobulin (Tg) is the primary tumor marker measured postoperatively to monitor for recurrence of thyroid cancer.  Tg concentrations reflect the mass, or amount, of residual thyroid tissue — remnant or tumor. An unexpected elevated Tg result which is not consistent with clinical findings and history is distressing for the patient and can lead to… Continue reading Falsely Elevated Thyroglobulin – HAMA

Basic Testing Information

Thyroid Level Testing for Thyroid Cancer Patients This is a basic outline of the thyroid tests most frequently asked about and are needed to properly monitor thyroid hormone replacement (THR) levels for thyroid cancer patients.  TSH - Thyroid Stimulating Hormone: is a hormone produced in the pituitary gland, a small organ located below the brain,… Continue reading Basic Testing Information

Tg Testing with Antibodies

Thyroglobulin Testing When You Have Positive Antibodies (TgAb} Thyroglobulin (Tg) is produced only by thyroid tissue and is the primary marker for follow up thyroid cancer detection after total thyroidectomy. It is not generally used after a partial or hemi-thyroidectomy as the remaining thyroid lobe will still produce normal levels of thyroglobulin. If you have thyroglobulin… Continue reading Tg Testing with Antibodies
