I am the nurse at a university and we are looking at track athletes Vitamin D levels. What is the difference between total Vit. D level and 25 OH Vit. D? Does the findings between these two tests impact the recommended treatment for these athletes? The cost of the 25 OH Vit. D is significantly higher and we would like to justify if it is indicated.
