Hi Sharon, welcome... If you've recently had your childs vitamin D level checked, get the print out from the Dr. or Lab and it will tell you what the normal/reference range is for the age of the patient being tested.
Labs vary some on this figure depending on population studies and location. If you have the print out look for the "normal" score for the childs age.
Thanks for your reply.
However, the test is not one that has been carried out yet. I am a nutritionist and would like to test vitamin D3 levels in one of my paediatric patients. I do this often for adults and the range given for the lab I use is 51-163 nmol/L. However, this lab and another I use have both said that they don't have a 'normal' range for children. I just wondered if anyone knew what the normal range was for young children or whether it is the same as for adults.
Hi Sharon: Sorry but I only know the reference range for adults. At my lab it's anything between 30 ng/mL and 100 ng/mL. I thought there had to be a reference range for children since you'd need a 25 (OH) D in conjunction with other tests for a rickets diagnosis, etc.
I'll see what I can find out...
The reference range of total vitamin D (25-hydroxy) for ALL ages is 32 to 100 ng/mL.
