Can you have thyroid problems with normal blood work?
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.
Can you have Graves disease with normal T3 and T4?
Graves’ disease may present only with subclinical hyperthyroidism (normal total and free T3 and T4 with suppressed TSH levels).
What levels indicate thyroid problems?
Normal test range for an adult: 0.40 – 4.50 mIU/mL (milli-international units per liter of blood). T4: thyroxine tests for hypothyroidism and hyperthyroidism, and used to monitor treatment of thyroid disorders. Low T4 is seen with hypothyroidism, whereas high T4 levels may indicate hyperthyroidism.
Why is my TSH low but my T3 and T4 are normal?
A low TSH with normal free T4 and T3 levels is consistent with subclinical hyperthyroidism. Some patients with nodular goiter and Graves’ disease, particularly early in the disease course, will have predominant elevations in T3 due to increased conversion of T4 to T3 and a disproportionate increase in T3 secretion.
What can mimic thyroid problems?
Blood Disorders Disorders of red or white blood cells can mimic thyroid disorders with symptoms like fatigue, weakness, feeling cold, excessive sweating, pale skin, easy bruising, shortness of breath, leg cramps, difficulty concentrating, dizziness and insomnia.
Can I have 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.
Can you still have hyperthyroidism with normal TSH levels?
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.
When T3 and T4 are normal but TSH is high?
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.
