TSH Testing: The Key to Unlocking Your Thyroid Health

What is TSH and How Does It Work?

TSH is produced by the pituitary gland and regulates thyroid hormone production. It has an inverse relationship with thyroid hormones - when thyroid hormone levels are low, TSH increases to stimulate more production, and vice versa. This sensitive feedback loop makes TSH an excellent indicator of overall thyroid function.

Understanding TSH Test Results

Normal TSH ranges can vary by age and other factors. Generally, a TSH between 0.4-4.5 mU/L is considered normal for adults. Higher levels may indicate hypothyroidism, while lower levels could suggest hyperthyroidism. However, interpreting results requires considering the full clinical picture.

When to Get TSH Tested

TSH testing is recommended for people with symptoms of thyroid dysfunction, those with risk factors like family history, and as a screening test in some cases. It's also used to monitor thyroid hormone replacement therapy. Your doctor can help determine if and when you need TSH testing.
