Standard

What does it mean when your T3 is low and your T4 is high?

If the levels of T3 and T4 in the blood are too high or too low, there is an imbalance between the amount of thyroid hormones needed by the body and the amount of thyroid hormones available.

Why TSH is high and T3 T4 is normal?

Normally, low levels (less than 5 units) of TSH are sufficient to keep the normal thyroid gland functioning properly. When the thyroid gland becomes inefficient such as in early hypothyroidism, the TSH becomes elevated even though the T4 and T3 may still be within the “normal” range.

Can you have low T3 but normal T4?

Subclinical hyperthyroidism is when you have low levels of TSH but have normal levels of T3 and T4. If you’re experiencing symptoms of subclinical hyperthyroidism, your doctor can use a series of blood tests to come to a diagnosis.

Can I have thyroid disease with a normal TSH and T4?

Yes, it is possible to have hypothyroidism and normal TSH levels in the blood. Most people with hypothyroidism have high TSH because their thyroid gland is not releasing enough hormones. In response to this, the body produces more TSH in order to get the thyroid to work.

What causes T3 to be low?

Low T3 levels. Depending on your situation, this can be the result of different medications, recent thyroid surgery, radiation therapy, pregnancy, or iodine deficiency. Another cause of hypothyroidism is Hashimoto’s thyroiditis, which is an autoimmune disorder where your immune system attacks your thyroid gland.

What does a low T3 and normal TSH 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. If you have questions about your results, talk to your health care provider.

Can you have symptoms of Hashimoto’s with normal TSH?

Having only the TPO antibodies present with normal TSH and free T4 levels means that your thyroid is functioning normally and you don’t have hypothyroidism, but it does mean that you may have Hashimoto’s disease. Remember that Hashimoto’s doesn’t always cause hypothyroidism.

What levels indicate Hashimoto’s?

How is Hashimoto’s disease diagnosed?

  • Thyroid stimulating hormone (TSH) test: A high TSH level most commonly means the thyroid gland is not producing enough T4 hormone.
  • Free T4 test: A low T4 level suggests that the person has hypothyroidism.
