Low Tsh 3rd Generation
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
Tsh 3-8.75 last 3 years (fluctuating)-hypo sympt. Prolactin a bit high.Serum am cortisol norm but free urin. Low. Saliv cort 4pt flat low.Indications?
Hormone measurements: You have had a lot of hormones tested, but all seem more/less normal. If the TSH is high, the prolactin can often be slightly high too. If hypothyroid, treating with levothyroxine normalizes both. Adrenals sound fine, but the next test would be an acth stim test (but i don't think you need it if the am cort was really normal). Maybe your sx are not due to hormones at all. Something else? ...Read more
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
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/t4 norm. T3 (liothyronine) slight low. Was on syn. 150mcg changed to150mg armour. Miscalculation error. Wt loss, tachy, palp, no sleep in 2 wks. Tinnitis. Help?
normal Total T4, T3 (liothyronine) Uptake, FTI, Ultrasensitive TSH
LOW Total T3 (liothyronine) (63.55 ng/dl)
Synthroid dose needs to increase?
It's OK: Hi. Your TSH is "normal", but I'd shoot for a value on therapy generally around the 1.0-1.5 range. The total T4, T3 (liothyronine) resin uptake, and FTI are prehistoric tests no one in the thyroid field has used for years. Your body regulates conversion of T4 to T3 (liothyronine), so your T3 (liothyronine) should be just what the body ordered. Your T3 (liothyronine) is close to the normal range; if you repeat it it's likely to be within normal range. ...Read more
My thyroid numbers:

Free T4, 1.06 ng/dL
Free T3 2.8 pg/mL
Reverse T3 15 ng/dL
My son's on synthroid (thyroxine). But are MY numbers optimal?
Interesting question: Optimal is a interesting question. First it is important to understand where "normal" is derived. "Normal" ranges for each lab is a statistical number that tell where a population of "normal" people results run. So your numbers run within the "normal" (reference) range for most laboratories. Are your results "optimal" is a question that is thus difficult to answer! ...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
Does free t3 (liothyronine) include rt3 (liothyronine) in the result?
Ft3 (liothyronine) was 6 which was almost top of range(6.8)but still hypothyroid symptoms. Tsh 2.71
Reverse T3 (liothyronine) dominance???
Total thyroidectomy 4 mo ago. High TSH & t4, low t3 (liothyronine). Feeling very hypo. Increases in levothyroxine not helping symptoms. Sliding downhill fast! Help!
Thyroid: Something does not sound right. A high TSH with a high T4 is very uncommon. It is possible, but unlikely that your pituitary gland is producing too much TSH. You need to see your thyroid surgeon or your regular doctor as soon as possible. ...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?
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
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 moreSee 2 more doctor answers
Free T3 (liothyronine) high, thyroid peroxidase ab greater than 1000, thyroglobulin ab elevated but TSH ultrasensitive normal as well as thyroglobulin. ?
Autoimmune thyroid: All this says is you have hashimoto's thyroid disease. Nothing else specific. Are you taking thyroid medication? What kind? ...Read more
Yes: Your TSH level is higher than normal and suggests thyroid deficiency. Please consult with your doctor to see if thyroid supplementation is warranted. ...Read more
I had normal tsh, t3, (liothyronine) t4, but antithyroglobulin antibody level is 263 and thyroid uptake showed homogenous uptake at 56%. What should I do?
Auto immune thyroid: Your thyroid functions are normal presence of thyroglobulin antibodies indicate autoimmune disease though more sensitive test is tpo autoimmune disease makes thyroid inefficient and hence iodine trapppping is increased of these people 30 percent will develop undersctivity. ...Read more
Dx hypothyroid in April, been on synthroid (thyroxine) 0.025mg x 3 months, but TSH went higher (~13) w/ normal ft4. Could viorele birth control cause high TSH?
What's the next dose: Don't think so. More likely it is because 0.025mg is the smallest Synthroid (thyroxine) pill. Synthroid (thyroxine) comes in about 12 sizes, from 0.025mg to 0.300mg. If one's doctor started her on 0.025mg and there is no drop in the TSH, one can ask at her follow-up visit (there is always a lot of follow-up until the proper dose is found and the TSH is normal) what the next dose is. ...Read more
I m 66yr my TSH 0.8 ft3 (liothyronine) 4.7(2-3.6) ft4 0.2(0.8-1.5) hb 10.2. Have hypoprotinimea, 7 albumin and 3 RBC transfusion in feb. Why low T4 and high t3 (liothyronine).
Medication?: You indicated that you are on thyroxine. I have a feeling that you are taking thyroid medication that contains t3, such as Armour Thyroid or Cytomel (liothyronine). These medications will cause a high t3 and low T4 level, but the TSH will be normal. If the ft3 and ft4 levels were done correctly, they should not have been affected by your low protein problem. ...Read more
Graves and RAI 12 years ago. 125mcg synthroid (thyroxine). All levels normal. 6 years ago TSH dropped to 0 and Free T3 & T4 low normal. TSH won't increase?
How do you feel?: This is really the question to be asking. Whoever is managing you may feel a need to lower your dose slightly to see if TSH rises / protect you from osteoporosis later in life / practice defensive medicine, but I'd be most concerned with how you actually feel. If you don't recognize symptoms / signs of hypothyroidism / hyperthyroidism, perhaps doing what's working is best. ...Read more
