Update on Free T3 Testing

There are a few circumstances that may affect Free T3 (triiodothyronine) test results.  The following two test descriptions from LabCorp, a major nationwide diagnostic laboratory, indicate conditions which may interfere with testing and when the Dialysis and LC/MS-MS may be preferred.  Biotin may interfere with Free T3 and other thyroid tests.  Thyroid antibodies may interfere… Continue reading Update on Free T3 Testing

Basic T3 Startup

The first step to adding T3 to our thyroid hormone replacement regimen following total thyroidectomy (TT) is understanding what T3 is and how it works. The two thyroid hormones are thyroxine (T4) and triiodothyronine (T3). A healthy thyroid produces mostly T4 and smaller amounts of T3.  This production is controlled by a “negative feedback loop”… Continue reading Basic T3 Startup

TSH Suppression

There are two primary dimensions in follow up treatment for thyroid cancer. The first is focused on preventing and identifying recurrence while the second, often overlooked in the quest to "beat cancer" is supporting your Quality of Life (QoL). Some endocrinologists and other providers may not always be aware of the need to keep TSH… Continue reading TSH Suppression

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

Suppression vs QoL

Why is TSH suppression so often the sole or primary goal in thyroid cancer treatment with little regard for Quality of Life (QoL)? We are told, over and over, that the vast majority of thyroid cancer patients do just fine for the rest of their lives on synthetic thyroid hormone replacement (THR) therapy evaluated by… Continue reading Suppression vs QoL

What Blood Tests Should I Request?

As thyroid cancer patients, when things are not going well the first place we tend to look is to our thyroid hormone replacement (THR) meds. Just as our thyroid interacted with every aspect of our physical and mental health, metabolism and daily activity, we need to remain aware of how our overall health works withn… Continue reading What Blood Tests Should I Request?
