If you’ve recently had a thyroid blood test and found terms like TSH, T3, and T4 on your results, you’re not alone in wondering what they mean. Your thyroid gland, although small, has a major impact on your health—from energy levels to weight balance and mood. At Health Today in Calgary, we believe that understanding your test results empowers you to make informed decisions about your health. At Health Today, we will walk you through the essentials of thyroid function tests and what your numbers might be telling you. 

Understanding TSH: Your Thyroid's Master Regulator 

TSH (Thyroid-Stimulating Hormone) is produced by the pituitary gland and acts as the main controller of your thyroid. When TSH levels are high, it usually means your thyroid isn’t producing enough hormones—commonly referred to as hypothyroidism. Low TSH levels can point to an overactive thyroid, or hyperthyroidism. 

Interpreting TSH levels can be confusing without medical guidance. Normal TSH ranges are typically between 0.4 and 4.0 mIU/L, but what’s “normal” can vary slightly by lab and individual health history. If your levels are outside the expected range, Health Today’s private thyroid function analysis in Calgary offers tailored testing and follow-up consultations to help clarify what’s going on. 

What T3 Tells Us About Your Thyroid Function 

T3 (Triiodothyronine) is one of the primary hormones your thyroid produces and plays a crucial role in how your body uses energy. It affects everything from your heart rate to how well you burn calories. 

Low T3 levels might indicate hypothyroidism, especially if accompanied by high TSH. High T3 levels are often found in hyperthyroidism and can be linked to symptoms like anxiety, restlessness, or rapid heartbeat. Because T3 is a more active hormone, it’s a vital piece of the thyroid health puzzle. 

At Health Today, we provide comprehensive thyroid screening in Calgary that includes T3 testing, so nothing important is missed when reviewing your hormonal health. 

T4: The Steady Workhorse of Your Metabolism 

T4 (Thyroxine) is the most abundant thyroid hormone in your bloodstream and acts as a reservoir for T3. It’s converted into T3 as your body needs it. T4 levels help determine whether your thyroid is functioning properly in producing enough hormone overall. 

A low T4 level with high TSH often points to primary hypothyroidism. A high T4 with low TSH may suggest hyperthyroidism. Tracking T4 levels over time is also useful for those managing thyroid conditions with medication. 

If you’re undergoing treatment or suspect an imbalance, private thyroid monitoring through Health Today in Calgary helps ensure your hormones stay in check, and your symptoms are well managed. 

Thyroid Imbalance Symptoms You Shouldn't Ignore 

Whether it’s unexplained fatigue, mood swings, sudden weight changes, or cold sensitivity, your body may be signalling a thyroid issue. Other symptoms include hair thinning, irregular periods, or digestive changes. 

Thyroid conditions are more common than many people think—1 in 10 Canadians will experience a thyroid disorder in their lifetime, and many cases go undiagnosed. That’s why early hypothyroidism detection in Calgary is key to improving long-term outcomes.

A single blood test isn’t always enough. Understanding your thyroid health means looking at the full picture—TSH, T3, and T4 levels together, along with your symptoms and medical history.
