Low T4 Thyroid
Low TSH Borderline low T4 normal t3 (liothyronine). Thyroid uptake scan..low uptake noted w\o nodules. Radiologist said HYPOTHYROIDISM?! All other possible test norm
Need follow-up: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, there is inconsistency in your results. Both TSH and T4 being low does not add up. You may need to repeat the lab tests, not necessarily the scan, in about 6 months to see what direction these results are going in. ...Read more

We have case , femal patien , age 60 years, the TSH less than 0.05 while T4 in normal range , and she has not any symptom of thyroidism , is it ok ?
Subclinical hyperthy: A low TSH with a normal T4 and no symptoms is usually subclinical hyperthyroidism. She may have a multinodular goiter that is autonomously functioning, or very early graves disease. A T3 (liothyronine) level and free T4 level should be checked. There is a higher risk of developing atrial fibrillation despite the normal T4 level, but many endocrinologists would just follow her levels for progression. ...Read more

My TSH is a little low. T4 is a little high. I can't take the thyroid meds. Will a partial thyroidectomy help? (feeling very sick)
Possibly.: If you can't take thyroid meds, surgery or radioactive iodine ablation are useful. In fact radioactive iodine ablation is effective, with 40-70% of patients becoming hypothyroid after its administration. You might want to just observe since your T4 and your TSH are only slightly high and low respectively, and you might still have normal function. It would be best to see your doctor to decide. ...Read moreSee 1 more doctor answer
I have a 1.6cm single vascular nodule right lobe of thyroid. It is 16x15x7mm, hypoechogenic,curcumscribed, front of neck has pain. T4 low biopsy?
FNA biopsy: Hi. TSH would be more useful than a T4, but I can surmise it's NOT a hyper functioning nodule from the low T4, and hyper functioning nodules are the only ones at no risk of being cancer. You need a fine needle aspiration (FNA) biopsy with gene testing. Let me guess...that's what your doc told you! She/he is right! Get it done. They're not bad at all ( know it seems creepy!). Odds are in your favor ...Read more

Normal TSH but low free t4? Whats th3 difference between these 2 test? Do I have a thyroid problem?
Reproducible?: Hi. Is the lab profile with normal TSH and low free T4 reproducible? The labs should be repeated. If the free T4 was just below the normal range, and on repeating it's in the normal range, then your thyroid function is normal. If free T4 is significantly low and TSH is normal, that suggests pituitary disease affecting the pituitary cells that make TSH. Good luck! ...Read more
My TSH levels are normal, my T4 is almost low? what could this mean? I have 3 hyperechoic nodules on a diffused thyroid. Size .09 to 1.5 CM.
Good evening. I've been suffering from whole body swelling. My TSH is low, and my free T4 is lower on each subsequent test. Is this a thyroid issue?
NOT REALLY: it sounds more like a PITUITARY condition. The pituitary gland (called the "master gland" is located below the base of the brain and REGULATES thyroid function AND the functions of other glands as well! Hope this helps! Dr Z ...Read more
Would TSH 5.4 and T4 7.6 be considered mild or severe? What test would my doctor have to do to know what caused my thyroid to be low?
Mild; repeat test: In most assays, the T4 is normal, and TSH slightly elevated. This could be nothing; sometimes a repeat test will come back normal. The question to ask: is your thyroid gland starting to fail? If so, it is early. Family history? Do you have symptoms? Positive anti-tpo antibodies? If you have symptoms and if there is evidence that your thyroid is failing, you should start on levothyroxine. ...Read more
