Based on years of patient testing and data analysis we have updated our laboratory report reference range to reflect that values between 20 80 ng ml.
Vitamin d levels range.
Hypercalcemia in turn can lead.
That is 86 of patients tested fall within this range.
1 25 dihydroxy vitamin d or 1 25 dihydroxy level or 1 25 oh 2 d has the normal values are usually listed as 20 76 pg ml.
The recommended daily amount of vitamin d is 400 international units iu for children up to age 12 months 600 iu for ages 1 to 70 years and 800 iu for people over 70 years.

Because vitamin d increases calcium absorption in the gastrointestinal tract vitamin d toxicity results in marked hypercalcemia total calcium greater than 11 1 mg dl beyond the normal range of 8 4 to 10 2 mg dl hypercalciuria and high serum 25 oh d levels typically greater than 375 nmol l 150 ng ml.
