(1) Determination of 25(OH) Vitamin D3 in human serum samples and (2) Question based screening tool with personal (age, gender,...), lifestyle (e.g. sun exposure, outdoor activity) and dietary factors that affect the status of vitamin D in the human body.
Difference between vitamin D status (deficiency) assessed by two different methods
Vitamin D serum level will be measured for assessment of Vitamin D status. Risk for vitamin D deficiency will be assessed using questionaire-based screening tool. Two methods will be compared.
