Question: I had TSH of 10.7 put on levo .5 about two months now TSH is in normal range but t3 is low. Is that normal.
Answered by Dr. Aparna Kohli 27 hours later
Thanks for writing to us.
The T3 levels should ideally be in the normal range and this indicates that the levothyroxine dose may have to be adjusted. But before doing that, I would like to repeat the tests to make sure that these reports do not indicate a laboratory error. Please see your physician and get a fresh test ordered. If the reports are still the same, we may want to adjust the dose of levothyroxine.
Also, I would want to know about the free Thyroxine levels.
Hope that helps. let me know if you have any more questions.

Free t4 1.2. Total t4 8.2. TSH 2.08 total t3 69.2. Done at the same lab as first my TSH was 10.7. Range .35 - 5.5. Surgery for next week. Just want to know what the scores mean. Working with a dr who didn't feel the need to do ultra sound or the biopsy. I try to be proactive as possible which requires knowledge if hadn't insisted on biopsy cancer may not have been detected for a year with next physical. Perhaps PTC with hurthl cell is not a major concern?

Papillary cancer is rarely picked up by a fine needle aspiration cytology. We usually get a better picture when we send a larger sample to pathology. A biopsy or a surgery is a better option in that regard. Since you already did have PTC, chances of recurrence are minimal since this is usually a cancer which is not very aggressive.
Both the free T4 and T4 lie within the normal range. The T3 is lower which indicates lower peripheral conversion. Are you receiving any other drug apart from levothyroxine?
Its possible that thyroxine is not getting converted optimally into thyronine (T3) and I dont think you need to be worried about that. The T3 is not significantly abnormal for me to start worrying about it. Also, this is also sometimes seen in a non thyroidal illness syndrome but I dont think that is the case here.
In all, I think you're fine as far as the thyroid status is concerned and the surgery should go off smoothly
Hope that helps

II have fairly large swelling in the middle of my neck just above my adams apple. I have had thyroid blood tests and ultra sound scan all negative. Could it be a thyroglossal cyst? I know is not normal to have such huge swelling in my neck and now feel a bit worried. I can actually move it from side to side.

Hi! I am Jun, 49 y.o., 5'3'', 160 lbs and had kidney stone treatment 20 years ago. My RBC reflected `too numerous to count' finding. I had urine culture, morphology and ultra sound tests performed. There is nothing painful I feel when urinating, no fever, etc. But I had five urinalysis already and was advised to drink lots of liquid but the condition `TNTC RBC' persists.

I'm 28 yr old female, i have hair fall problem from past 3 to 4 years. My hair started thinning only in the front. I used several lotions like ervamatine, hair for u, for some days it was fine & later it gave me side effects like dandruff skin problems like acne. Recently i consulted a dermatologist where she asked me to take thyroid, blood test & ultra sound ( abdomon) all the tests was fine for me except for deficiency in Vitamin B12 & vitamin D. I was prescribed with Anaphase shampoo & neoptide spray. I'm still worried if this would solve my problem. Will neoptide spray has any side effects before i go ahead & use i wanted to be 100% sure. If i have to use them should i sue these products for life long?Please advise.
