What does a low T3 uptake mean?

What does a low T3 uptake mean?

Low T3 levels may mean you have hypothyroidism, a condition in which your body doesn’t make enough thyroid hormone. T3 test results are often compared with T4 and TSH test results to help diagnose thyroid disease.

What is considered a low T3 level?

Although there is no normal range agreed upon by all health care practitioners (some labs also have different ranges), the following ranges are generally considered typical for adults: T4: 5.0 – 11.0 ug/dL. FT4: 0.9 – 1.7 ng/dL. T3: 100 – 200 ng/dL.

How can I raise my T3?

Several health studies have shown that T3 and T4 hormone levels increase with exercise. Beyond helping to stimulate thyroid production, exercise also helps to counteract many of the side effects of hypothyroidism such as gaining weight, loss of muscle, depression, and low energy levels.

Does low T3 cause tiredness?

Some people with the condition known as chronic fatigue syndrome (CFS) have low circulating levels of the thyroid hormone triiodothyronine (T3) and normal levels of thyroid-stimulating hormone (TSH), new research shows.

What are normal levels of T3 uptake?

The range for normal values are: Total T3 — 60 to 180 nanograms per deciliter (ng/dL), or 0.92 to 2.76 nanomoles per liter (nmol/L) Free T3 — 130 to 450 picgrams per deciliter (pg/dL), or 2.0 to 7.0 picomoles per liter (pmol/L)

What does low T3 uptake mean?

Low T3 levels. Abnormally low levels of T3 may indicate hypothyroidism or starvation. It could also indicate that you have a long-term illness since T3 levels decrease when you’re sick. If you’re sick enough to be hospitalized, your T3 levels are likely to be low.

What does low T3 levels mean?

In general, high total or free T3 results may indicate an overactive thyroid gland ( hyperthyroidism ) and low total or free T3 results may indicate an underactive thyroid gland ( hypothyroidism ).

What does low TSH and high T3 and T4 mean?

The exact opposite is true when the TSH is low. A low TSH is an indicator that your body has enough T3 and T4 in the body and so your pituitary responds by reducing the production of TSH from the pituitary gland. Hyperthyroidism = excessive thyroid production = high T3 and/or T4 levels of thyroid hormone in the blood = low TSH.
