Thyroid Disease

HOW DOES THE THYROID GLAND FUNCTION?

In other words, T4 levels dictate how much TSH will be released.

Changes in thyroid transport proteins levels can be seen in pregnancy and in women taking the oral contraceptive pill.

If there is some concern about the protein levels, then a test called free T4 (FT4) test could be done. This measures the level of thyroid hormone that is unbound to protein.

Testing Thyroid Function

Thyroid function is easily evaluated through blood tests. Below are the commonly performed tests to asses thyroid function.

What is a Thyroid Scan and Uptake?

When something goes wrong.

If the gland produces too much (hyper) hormone we term the condition Hyperthyroidism. If the gland makes to little (hypo), we call this Hypothyroidism.

Hyperthyroidism or Graves' disease is an autoimmune disease.
