Question 1

i take 2000iu of vitamin d and drink milk yet my vitamin d was only 28. normal range is 30-100 according to lab. what would cause the low level?

Accepted Answer

Vitamin D : A higher dose may be needed. Absorption can be impeded by certain medications. Vitamin d3 is superior. A liquid or chewable formulation can be tried. A little of daily sun exposure may help.

Question 2

hida w cck was normal, ultrasound showed sludge pain in ruq luq and llq why? alkphos elevated wbc elevated slightly 13.  vitamin d 19  only abn labs?

Accepted Answer

Biliary: Sludge is a compilation of small stones, and can certainly cause biliary symptoms. The hida scan would not necessarily be normal, if you were just having colic. Add the slight elevation in WBC and alk phos, and i believe you are having biliary symptoms. It's atypical to have llq pain with this, and my not be related.Try a low fat diet, see if improve. Surgery my be necessary. Good luck.

Accepted Answer

: If your Calcium level is normal, then I would not worry about a low PTH. I suggest that PTH level and calcium levels be rechecked in 6 months. You should also consult a Endocrinologist for further advice.

Question 4

recent yearly lab work showed my vitamin d level was slightly below normal at 28. all labs good.doctor recommended i take vitamin d3 supplement. started 2000 international units a week ago and now i have noticed an increase in urination side effect?

Accepted Answer

: That is not a usual Side effect of a vitamin D supplement. If you think it is truly due to the supplement, stop it and contact your doctor.  good luck.

Question 5

we did cortisol test and it was 546.5 nmol/l. she suffers from underactive thyroid and vitamin d deficiency. 
according to lab its 2% above the normal range .
shall we consider a problem in cortisol? can thyroid contribute to this or vitamin d?

Accepted Answer

: Testing for adrenal cortisol diseases (low or high)  is complex and needs to be based on history, physicial, family history, meds being taken. Thyroid can contribute if VERY VERY low for a very long time.  You did not say if test was saliva, or blood or urine and always send normal values for that lab.  Best to consult with one of us here via video or better yet continue with the DR you are with.

Question 6

took lab order from 2 diff drs to get done. they ran vitamin d twice. one dr called and said its extremely low and the other said its fine. how common are lab work mistakes? makes me wonder what else they miss?

Accepted Answer

Results: What were the results? There are differences in results based on the method used and each lab has its own reference range.
If your level was less than 30 ng/ml you can safely take 2000 to 4000 units of vitamin D3 daily.

Question 7

is possible to have both vitamin d tests drawn in one blood lab?

Accepted Answer

: Yes, 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D levels can be assessed by laboratories. Although there are differences among Vitamin D methods, most laboratories utilize similar reference intervals. Because toxicity is rare, the focus has been on the lower limit and what cut-off for total 25-hydroxyvitamin D (D2 + D3) indicates deficiency [usually below 20 ng/mL  (normal 30-50 nmol/liter)].

Question 8

my lab results just came back and my health is in good condition but i don't have enough vitamin d. how will this show physically in/on my body?

Accepted Answer

Vit D Deficiency: Vit d deficiency can caue pain in bones and muscle, and in growing children can caue ricketts and in severe form osteomalcia in adults.But most of the times the symptoms may be so suble and you may not know you are deficient till blood test shows on blood test.We know now that vit d has a role in preventin cardiovascular disease, cancers, asthma in children, cognitive impairment in older people etc.

Question 9

whats the regular dosage for supplements for a 26 year old thats low (23- number on lab results) in vitamin d??

Accepted Answer

: Data suggest a dose of 4,000IU/d is well tolerated by most and can be continued long term. Some docs use higher dosing for deficiencies when they follow blood levels. A standard 2,000 IU/d is a common supplement for extended use.

Question 10
