Blood test says TSH rfx on abnormal to free T4 -349829 and TSH 0.035, T4 free (direct) 1.26 what does this mean?

Hard to say... It is difficult to say without knowing the units of measurement. For example a free T4 of 1.26 ng/l is normal but 1.26 pmol/l is quite low. A TSH value of 0.035 is defintely low and may indicate an overactive thyroid (hyperthyroidism). Consultation with your doctor or an endocrinologist is recommended.
Guidelines. According to recent guidelines your TSH would be considered as showing an overactive thyroid. However, your free T4 is definitely normal. Do you think that your TSH value was 0.35 instead of 0.035? If so, it would be within normal limits according to present guidelines.

What to do if I had a blood test done and my TSH reflex to free T4 is 4.53. 50-4.30 miu/l is that bad?

Further workup. A TSH above normal indicates that your brain is telling your thyroid it needs better thyroid function. Have your free T4, free T3 (liothyronine), (liothyronine) Reverse T3 (liothyronine), (liothyronine) thyroglobulin and TPO antibodies, Ferritin, and SHBG levels checked to ensure the thyroid and tissue utilization/conversion to active thyroid is occurring. Furthermore, these levels should be optimized...TSH 3.6, low Rev T3 (liothyronine) Read more...
Thyroid labs. Hi. That's probably early, subclinical hypothyroidism. It should be repeated with a free T4 and thyroid autoantibodies before any consideration is given to treatment. Go Hawks! Good luck! Read more...

I have a blood test done and my TSH reflex to free T4 is 4.53. 50-4.30 miu/l is that bad?

Mildly abnormal. That TSH is mildly high, implying that you may have mild hypothyroidism. The free T4 is likely to be in the lower range of normal. Most people with these numbers will have no symptoms at all. If you have hypothyroid symptoms and evidence for chronic thyroid disease, it would be reasonable to take thyroid hormone. Otherwise, you should have repeat levels in a few months. Read more...
I agree to a point! Tsh slightly elevated. Your body thinks your thyroid is low. The most common cause for hypothyroidism is hashimoto's thyroiditis, which can be indentified by the presence of anti-thyroglobulin antibodies and anti-tpo antibodies. Have these tests. If positive, i would place you on thyroid immediately. I would also have my free-t3 checked as well. Some do not convert T4 to t3! Read more...

I have hypothyroidism and im on Synthroid (thyroxine) 137 mcg 1/2 tab daily. My last blood test showed... TSH: 0.89, Free T4: 1.9. Is this to high?

It's OK. Hi. That TSH and free T4 are OK. The free T4 is just barely above the upper end of normal in most labs, and your TSH is fine. If you feel normal, there'd be no compelling reason to lower your dose. If you feel hyperthyroid in any way, you could try a lower dose. I'd repeat those labs in 2 months to assess stability. Good luck! Read more...

Blood test. Free T4 0.9ng/dL, TSH 0.91 mIU/L. Both lower end of normal. Hyperthyroid? Total T3 113ng/dL

Normal. Why were the tests done? Do you have any symptoms? Your results are in the normal range. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine. Read more...

I'm 28, a hypothyroid patient, trying to conceive, got blood test & it came out as TSH=0.54, Free T4=2.46, T3=1.40 are these numbers ideal 4 conceiving?

Probably. I'm not sure what units are being used to measure the free T4 and T3 (liothyronine). The most important number is the TSH and that appears to be in the normal range, so you can try to conceive. However, as soon as you know you are pregnant, you should have the levels rechecked as typically women require a higher dose of thyroxine when pregnant. Read more...

I had a us of my thyroid and they found a hypoechoic nodule measuring 0.413 x 0.546cm. Blood test came back normal TSH and free T4 really nervous.?

Please don't worry. One of the next steps is usually a fine needle aspiration biopsy, which involves using a very skinny needle to remove cells from the nodule. In my experience, most of these cells are benign, especially give the size of your nodule. However, if they are malignant or suspicious, you will need thyroid surgery. Most thyroid cancer (papillary type) can be cured. Read more...
F/U recommended. A .546 x .413 cm (ie 5x4 mm) thyroid nodule is extremely common. With normal thyroid function (normal TSH and ft4), in my practice i would simply recommend a follow-up thyroid ultrasound in 12 months to ensure stability. Less than 1% chance the nodule is related to thyroid malignancy. Read more...
Very common. Thyroid nodules are very common. About 70% of the population has a nodule (many don't know it). About 5% of nodules are cancerous, which is why we care. Unless there were concerning characteristics on the ultrasound like microcalcifications, taller than wide or increased blood flow or you have a family history or radiation exposure, typically we just follow-up with an annual ultrasound.

Too small to worry. Generally nodules that small are usually just monitored. This is a very common finding as many people have nodules. 95% are benign. I would not worry at this point. . Read more...
