Doctor insights on:
What Is Low Tsh With Reflex Ft4
No: Not if those values are within the lab's stated and assayed normals, and if your not on any medication to lower active thyroid hormones.
Hyperthyroidism: A low TSH and high T4 is an indication of over-active thyroid (hyperthyroidism). This should be evaluated further for any potential cause and discuss treatment options with your physician. Referral to an endocrinologist may be necessary.
Depends: On the level of tsh. If TSH level remains in the range 0.2-0.6, he is at very low risk of developing hyperthyroidism. Retesting is not recommended.
What does low TSH 0.2 with normal free T4 mean? What is its treatment and does it need to be taken all life long?
Likely normal: Your TSH may be slightly low and may be normal for you. Do you have any symptoms? It is generally not a good idea to treat lab values. All lab 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. It is likely that you need no treatment, however, it would be prudent to follow your doctor's advice for follow up tests.
Very low TSH with high normal free T4. Twitching. Changed dose. How long til levels normal out? Still twitching 2 weeks later. Had basic neuro exam.
What did you: Change the dose of? If it's thyroid replacement, it can take weeks for the level to normalize, asumming you're now on the correct dose. If it's an ANTI-thyroid drug, it can takes months to work as it only inhibits the formation of NEW thyroid hormone, not the hormone that's already been manufactured.
Could a low TSH but normal Free T4 mean a Pituitary problem? Or would that be more indicative of the start of Hypothyroidism?
Sounds normal: Your description is consistent with normal thyroid function, but if you are concerned, you could provide exact numbers for us to review.
Had total thyroidectomy 10 years ago. Currently 8 weeks pregnant, taking synthroid (thyroxine) 125mcg. Very low TSH 0.01 and high free T4 at 26 (normal 12-22).?
Way off: That dose of thyroid needs to be reduced ASAP. Please consult with your doctor right away. I'm guessing they're doing that already if they received those test results.
Thyroid antibodies are high, my free T4 low, TSH & free T3 (liothyronine) in normal range, on whole thyroid yet exp 2-4lb weight fluctuation & hair loss- what next?
Tsh, 3rd generation w/reflex to ft4 results are 0.89. I am fatigued, overweight, vitamin deficient, and sleep 10-11 hours/night. Is this result low?
Within normal limits: Your free T4 level is within normal limits. The symptoms you described do not lend to providing a meaningful opinion without more history, physical examination and the lab data. It would be prudent to discuss the matter with your doctor.
Tsh w/reflex to ft4 level is low at. 07 T4, FREE Level is with in range at 1.5 Thyroid peroxidase antibodies level high at 18 I had my thyroid removed 9 months ago due to cancer and am taking levothyroxin 125. With my latest blood results should I be con
Post op thyroid: Surgery for cancer the replacement thyroxine should be dosed sufficient to keep TSH low to avoid stimulating any tumor remnants. Most Endocrinologists advise suppressing tsh for about 5 years. Thyroglobulin levels and antibodies should also be measured. Your TSH level appears adequately suppressed. Thanks for trusting HealthTap!
High normal: A TSH of 4.06 is in the upper range of normal. The lab probably did not do the ft4 level, since the TSH was normal. Most people with these results feel perfectly normal. However, it could be a sign that your thyroid is starting to fail. It would be reasonable to repeat the TSH and do a free T4 level in a few months.
TSH w reflex to FT4 result is. 79. Is this normal? Last year same test result was. 91. ..what would cause difference?
Normal: Varies during the day, not significant, normal ft4 0.7-1.86 ng/dl, tsh 0.4-mcU/ml
Hi my TSH W/Reflex to FT4 is 4.54. what does this mean? Also my Cortisol is 26.8 what does this mean? Thank you Kindly.
Why testing?: More important is to ask why the blood tests were drawn and what other symptoms may be present. Also, lab values vary depending on the lab. In many labs, the values mentioned are normal.
TSH a tad low.: This number would suggest that your thyroid is a touch fast, as the TSH is a touch low. If you’re not having symptoms referable to hyperthyroidism then this could simply be a lab aberrancy. If you are having relevant symptoms, though, then you’d need a more formal investigation - full thyroid blood panel, thyroid ultrasound and scan.
HYPOTHRYOID: Your thyroid gland is underactive it is not producing enough thyroxine. The pituitary gland is working overtime to try to get the thyroid gland to produce enough thyroxine which regulates the bodies metabolic rate. You need supplementation of what your gland produces. You also need to be checked for autoimmune thyroiditis, see your doctor.
Hypothyroidism: Normal TSH is typically 0.45-4.5. Best to discuss results w/ordering physician as some labs have different reference ranges. Regardless, if you have signs & symptoms of hypothyroidism (underactive thyroid = http://www. Mayoclinic. Org/diseases-conditions/hypothyroidism/basics/definition/con-20021179), prescription levothyroxine will help relieve symptoms but requires close & regular monitoring.See 1 more doctor answer
Normal: This is a completely normal TSH. The free T4 was not done because the TSH was normal indicating normal thyroid function and the FT4 is not indicated. There are some rare circumstances when you would do both, and not just the reflex, but in general a normal screening TSH means normal thyroid function. Anything else would specifically being looked for and thyroid testing can rarely be complicated.
Normal: That's a normal value. That's why they didn't have to run the free t4. Reflex means they will run ft4 only if tsh is abnormal.
Thyroid tests: It is advised that you would benefit from an online consultation to review your labs as well as past medical history and discuss your specific symptoms. A physician can help you understand the labs, correlate with your history and make recommended next steps.
