What Is Tsh Reflex To Free T4
Few possibilities: These labs seem at odds, with TSH suggesting overactive thyroid and ft4 underactive thyroid. Free T4 tests can be inaccurate in some people who have interfering substances present. Another possibility is a tumor in the pituitary secreting too much TSH resulting in thyroid overactivity, and high thyroid hormone levels. This is quite rare, however. Your doctor can help sort this out. ...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 moreSee 1 more doctor answer
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?

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 moreSee 1 more doctor answer

TSH values: The TSH is your pituitary gland at the bottom of your brain talking to your thyroid gland saying "I don't see enough thyroid hormone around here." It stands for Thyroid Stimulating Hormone. You should speak to a good endocrinologist about your situation pronto and yes you should be on a higher dose of thyroid replacement hormone. ...Read more

Blood results came back with a 4.27 (h). Tsh, reflex to free T4 tsh, highly sensitive.
Leukocyte esterase - moderate
hemoglobin - trace / WBC 6 (h)?
Reverse T3 (liothyronine): Check free T3 and reverse t3. Ft3 should be in upper range and rt3 in lower range. If your ratio is off, you may need Armour Thyroid or t3, and synthroid (thyroxine) would be the wrong med for you. Also consider checking thyroid antibodies. ...Read moreSee 1 more doctor answer
Hi, I am a 37 year old female. History of excessive thinning hair. My TSH reflex to free T4= .9. My ferritin= 17. My calc % Iron Sat= 20. Thoughts?
Normal: Hair thinning is a very common complaint. Usually one can find no particular cause, though many medical conditions, medications, stress, age, genetics, nutrition, all influence hair growth. Your thyroid, and iron levels appear normal and are therefore unlikely to be a cause for hair loss. ...Read more
