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?
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 moreSee 1 more doctor answer

My TSH is 9 & my TSH Reflex to Free T4 is 1.29, I still feel Fatigued & I don't feel well should I have my Dosage of Levothyroxine increase to 100 MCG?
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
I had a TSH REFLEX TO FREE T4 blood test done, my result is 3.70 and my doctor is currently unavailable to go over the results. Please help.
Normal: Your TSH level is normal. A free T4 level would only be done if your TSH was abnormal, so it was not done. ...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

My TSH with reflex to free T4 and T3 (liothyronine) came out to a range of 1.0 . Is that normal ? Been feeling horrific since I gave birth 5 months ago .
That's a normal TSH: Hi. That's a normal TSH, but testing TSH alone only tests dysfunction of the thyroid gland itself. You need to get a TSH AND a free T4 (i.e., NOT "reflex") to see pituitary hypothyroidism (which, btw, can occur in rare cases associated with a particularly bloody delivery). Of course many problems can make you feel horrific. Can you make milk? I don't know what is wrong, but you need further eval. ...Read more
My t4 free is 0.70 and my tsh reflex free t4 is 29.2. What does this mean and what do I need to do?
Hypothyroidism: This is diagnostic of hypothyroidism and should be treated with thyroid hormone replacement which hopefully was done by the doctor who got these labs. While without a little more history is there is the remote chance of thyroiditis, it is unlikely with a TSH in this range. While EASILY TREATABLE, hypothyroidism can be a serious and even eventually a life threatening disease. ...Read more
My TSH w/reflex to FT4 test came back at 6.73, but my free T4 came back at 1.24. I have previous has similar results to these tests.
Mild hypothyroidism: The elevated TSH means that your pituitary gland is not happy with your thyroid level, and would like to see it higher despite the "normal" free T4 level. If you do not have any symptoms of hypothyroidism, we call this "subclinical hypothyroidism". Treatment may not be needed unless you develop symptoms or the TSH goes progressively higher. You should not start treatment based on one abnormal test ...Read moreSee 1 more doctor answer

TSH, 3RD GENERATION (0.40-4.00) uIU/ML My results are 1.10
I had this test taken. Can you explain what the results mean?
Normal, but...: THIS IS A NORMAL THYROID SCREENING TESTS. There are rare diseases thyroid that can happen with an normal normal TSH, but you would have symptoms of thyroid disease or other evidence of central hypothyroidism or thyroiditis in a "euthyroid phase," which would be rare and require much more history. If there is ongoing concern see an endocrinologist. IF YOU GENERALLY FEEL WELL GREAT, IT IS NORMAL! ...Read moreSee 2 more doctor answers
