Avatar n tn is 1200 iu of vitamin D to mauch during the first trimester? I have read anywhere from 400iu to 4000iu.
1597714 tn?1299828089 Don't be scared - your numbers don't look bad at all. Some folks wouldLOVE those numbers. FreeT4 is mid-range, FreeT3 is pretty low though and the TSH looks like a decent number - but what matters is how you feel. See what a difference knowing the lab reference ranges make? None of those tests are for Hashimotos. You need the AntiTPO and TGab blood work for that diagnosis. Barb recommended having your Vitamin D3 & B12 checked.
Avatar m tn What is the reference range for the calcium and what is the exact level of PTH, with reference range? Your calcium seems to be slightly elevated, but that would depend on the reference range used by your lab. How often do you take the 50,000 iu of vitamin D? Maybe you need to take it more often?
171867 tn?1271044148 I have low Vitamin D too and am on a supplement. My doc just told me that I should be over 50 ng/dl right now and I am at 43.4 ng/ml (4.8-52.8). Your range is different from mine though. I am now taking 5000 units a day. I do not have any symptoms from being low though. You said Free T3 is low? Maybe that could be the problem. Are you taking supplement for Vit D too?
Avatar m tn I agree with armywife92 about the Vitamin D. Reading between the lines, i thought about Low Vitamin D often being associated with being hypothyroid, and since you were tested for TSH and FT4, I wondered if perhaps you had symptoms that resulted in these tests, especially for thyroid. I imagine that with your TSH being within the old reference range listed, and your Free T4 being in range, that the doctor decided you were "normal" as far as thyroid issues.
Avatar f tn Hi Dr. Smita, Thank you for your response! Actually, I had all my blood test checked (calcium, magnesium, TSH,...etc) Everything came out normal except vitamin d is low. Could it be vitamin d deficiency and calcium still can be normal? I don't understand. My doctor prescribed me 50,000 IU vit. d once a week x 12 weeks and I'm taking Gapapentin 300mg at night from my neurologist for sleep. What he told me my twitching is benign and don't worry about it!
Avatar m tn Also do these basic blood tests Vitamin D. Vitamin B12 and Ferritin. Out of these Vitamin D or 25-hydroxy Vitamin D3 test is very essential as over 90% of hypothyroid people are usually low on this.
Avatar f tn There are differences among Vitamin D methods, making a universal reference range difficult to establish. Total 25-hydroxyvitamin D (D2 + D3) is the correct measure of Vitamin D status. There is currently no consensus on the level which indicates deficiency." I do know that for myself, the most recent test result was 45, with the desired level indicated as being >30. If you have a test result for yourself, the best way is to look at the lab report and see what reference range is shown.
1548028 tn?1324612446 My Vitamin D level was checked during my DX process last September. My total # was 25 ng/mL. The reference range is 30-100 ng/mL. My D3 # was 25 and my D2 # was <4. I now take 5000 IU/day.
4274823 tn?1388529098 Thank you very much for your reply and the info. Yes, I am aware that my local lab is using an outdated reference range. I feel cold, have skin issues, am emotional, and prone to stress. I am taking a combo of sublingual B12 and B complex (alternating days). Perhaps I should take more sublingual B12 and less B complex (as dose is significantly lower for B12 in the B complex).
Avatar m tn That Vitamin D level is too low. Should be at least 50, so you should discuss with the doctor, supplementing with about 2000 IU daily.
