Tsh With Reflex 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
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
TSH W REFLEX FREE T4
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
TSH reflex free T4 test = 2.51 (normal range 0.35-4.50). I've read hyperthyroidism still possible if TSH normal. Do I need another test?
TSH w/reflex to T4 was 0.25. T4 free 1.2. T3 free 2.7. Tsh level was higher and synthroid (thyroxine) 137mg. Still on same dosage. Would this cause fatigue?
Possibly.: The low TSH with associated normal free T4 and free T3, (liothyronine) suggests borderline hyperthyroidism (overactive thyroid) which can cause fatigue. However, one should seek a thorough medical exam prior to concluding that the symptom of fatigue is not due to some other problem. ...Read more
Tsh with reflex free T4 1.09, free T4 1.00 t3 (liothyronine) total 91 .Feel horrible very weak, hair falling, weight gain endo and GP said I'm fine no further tests?
TSH w/reflex to T4 was 0.25. T4 free 1.2. T3 free 2.7. 4 months ago TSH 2.01. Synthroid (thyroxine) 137mg year. Fatigue weight gain hair loss. Suggestions?
Not hypothyroid: Your TSH was within normal range(0.4-0.6 ) 4 months ago indicating you were not hypothyroid then and were on the proper dose of Synthroid (thyroxine). Your current Free T4 is within normal limits. However your TSH is slightly low which suggests that your current dose of Synthroid (thyroxine) is slightly too high and can be reduced. YOU ARE NOT HYPOTHYROID and your symptoms are not due to this. ...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
