Published reference ranges
Published values for 25-OH Vitamin D3 vary along 3 axes:
- season
- latitude
- supplementation
Because a single unstratified figure would misrepresent them, none is shown here.
Published values vary by sex, age, time of collection, menstrual cycle phase and analytical method. The interval applicable to a patient's result appears on that patient's report.
