Low Tsh 3rd Generation Readings
My thyroid numbers:
TSH 3.38 mcIU/mL
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 3-8.75 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
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
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
Thyroid removed in Oct. Now high bp, pulse rapid, fatigue. TSH low, T3, (liothyronine) T4 normal. Cardiac tests normal. Endo says stop thyroid meds. Will this help?
RollerCoasterWillEnd: I'd take his suggestion.It's a period of adjustment & you'll need to fiddle with your meds until you find a happy balance.I suspect you won't be off the medication for very long unless they left something in there.But if you start to feel sluggish it's time to contact Mr or Ms Endo.I'm sure you've already arranged follow-up, right?? Oh, and those numbers are important, but more so how you feel. ...Read moreSee 1 more doctor answer
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
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
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?
Blood test results showing high creatine 1.28 and low egfr 55. Glucose is normal but 99. All were normal 6mo ago.No diabetes. Hypothyroid&Hashmotos.
Kidney disease: What you are describing is stage 3 Kidney disease, but the labs should be repeated along with urine protein level. If you have high blood pressure, it needs to be controlled. There is treatment to prevent or delay worsening, so talk to your doctor! ...Read moreSee 1 more doctor answer
Glucose serum112 mg/dL,T3 (liothyronine) free 2.5 pg/ml,T4 free 1.14 ng/dl,TSH 2.180 uIU/ml-blood test taken PM-no fasting/no meds told have hypothyroidism-confused?
Taking thyroid med?: Hi. Those thyroid function tests are normal. If you're not taking thyroid hormone, then you're not hypothyroid. I'm sorry for the confusion; no one should have told you you're hypothyroid based on those labs. I would advise against taking desiccated porcine thyroid (Armour). See an endocrinologist if you want expert opinion on thyroid issues; many excellent ones in your area. Your thyroid's normal ...Read more
Blood test TSH 3.40--considered "high" per lab . Has reference range changed lately? Free T4 .9 (normal range)
have thyroid nodule, prolactinoma
Recently had pituitary surgery. Current cortisol levels bl 4.1, 30 min a/i 18.6, acth plasma level 6. All numbers seem low, dr said norm. Second opin?
Don't know enough: About your case to be specific. I assume the "a/i" is after syncortropin injection, which is an appropriate response, but only checks your adrenal glands. Cortisol and acth are slightly low but not dangerously so. I would discuss your concerns with your doctor. ...Read more
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
Normal: Your tsh falls within the normal range; actually on the better half of the normal range. If you're still worried, check the free hormones as well but so far so good. ...Read more
Thyroid nodule. FNA benign. male. Last 2 tests. TSH high normal 4.0, and 4.2. FT4 Normal. TPO AB high at 39 (0-9 range)
do I need medication?
No: One of the questions with regard to thyroid nodules pertains to number and activity of the nodule. If on scan one sees several nodules, the dx for the most part is goiter. FNA can easily miss the nodule or can be read as an adenoma. A functional scan should be performed. If hot the nodule should be left alone. If the solitary nodule is cold there is a 30% chance the nodule is or will be Ca. ...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

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
