Tsh 3rd gen 0.085 et ft4 0.59..What cause?

Tsh 3rd gen 0.085 et ft4 0.59..What cause?

Both are low?: If both TSH (from the pituitary gland in the brain) and free T4 are low, it may be that the pituitary gland is not secreting enough TSH to stimulate the thyroid gland to make more t4. Then endocrinologist can do additional tests to see if this is indeed the case. ...Read more

TSH 3 in nov 2014 & 0.05 in jan 2015. Sleep disturbance after starting Synthroid (thyroxine) 88mcg. Tiredness. Sad. Am I overdiagnosed with hypothyroid?

Yes, over diagnosed: Hi. Based on what you've told us, there is no reason to suspect you're hypothyroid. How long have you been on the l-thyroxine? It is most likely you have no thyroid disease and are being treated with l-thyroxine needlessly. Are your thyroid autoantibodies positive? Even if so, decision to treat is based on TSH and free T4. Good luck! ...Read more

Thyroid nodule: follicular lesion, T4 free is low, T3 (liothyronine) free is low, and TSH 3rd generation is now low. 60 mg of armour thyroid, 50 mcg levothyroid why?

Thyroid nodule: follicular lesion, T4 free is low, T3 (liothyronine) free is low, and TSH 3rd generation is now low. 60 mg of armour thyroid, 50 mcg levothyroid why?

Stop Armour: There is no way to check your levels or keep your thyroid in control in your current regimen. Armour thyroid is ground up pigs. Switch to brand name T4 only and get it regulated. Also, have repeat thyroid biopsy with afirma test and consider surgery to remove nodule depending upon lab and ultrasound. ...Read more

What is high tsh, 3rd generation?

What is high tsh, 3rd generation?

Same as others: The 3d generation TSH assays are best at the lowest ranges - the upper range is debatable as tsh, unlike most products in the blood is not distributed in populations in a bell curve. The upper limits of the "normal" range of 4 to 5 in assays of all generations is probably wrong. ...Read more

My TSH 3rd generation test came back at 2.036. The range is 0.340-5.600uiu/m. The test said high sensitive 3rd generation tsh. What does this mean?

My TSH 3rd generation test came back at 2.036. The range is 0.340-5.600uiu/m. The test said high sensitive 3rd generation tsh. What does this mean?

Not a whole lot!: An elevated TSH is the main criteria most docs use to diagnose hypothyroidism. While most docs feel it is not abnormal unless above 5.6 or so, many endocrinologists feel anything above 3 is abnormal, and some even feel a level above 2 could indicate problems- see http://abt.Cm/1562fwq actually, many with a totally normal TSH may still have thyroid problems- see http://bit.Ly/18atkro & comment:. ...Read more

See endocrinologist: Assuming that you have rec'd no treatment, the extreme changes in thyroid (; tsh) function plus the high anti-tpo suggest that you are having active thyroiditis and need to see an endocrinologist. ...Read more

Likely too much meds: It appears you've been over medicated and that your thyroid is at a high level of function for you. Even if the thyroid levels are in normal range, they are still very robust and just came down from much higher levels. It would take time for an adjustment to affect all levels and so these can be why TSH is low. If it persists, another visit to your doctor may be needed to lower meds. Good luck. ...Read more

Tsh levels are these normal? Tsh- 3rd generation- 1.04 miu/l , then another one was 0.63 miu/l. Tsh w/free T4 rfx 1.50 miu/l. Are these normal levels?

Tsh levels are these normal? Tsh- 3rd generation- 1.04 miu/l , then another one was 0.63 miu/l. Tsh w/free T4 rfx 1.50 miu/l. Are these normal levels?

Probably: Most labs include a reference range (or normal range) in their reports. While there can be some variation from one lab to another, almost all labs would consider TSH values between 0.5 to 3.0 to be normal. All three of your levels fall in this range, and so would be considered normal. ...Read more

Diagnosed with hypothyroid Tsh 12.3 3 months ago, been on Levo 75 mg yet still have fatigue & brain fog. Did a 2nd test last week. result: Tsh 5.3 ?

Hypothyroidism: While most labs in States use 0.45-4.5 as normal range, many will aim for 1-2 when treating hypothyroidism (underactive thyroid). We (re)check TSH every 6wks after dose change. Assuming no side effects, we'd recommend increasing your Levothyroxine dose to 88 or even 100mcg daily, then rechecking TSH in 6wks. Goal should really be making you feel normal, not just making numbers normal. ...Read more
