Vitamin D Testing
Vitamin D levels fluctuate significantly depending on the season, especially in the Southern states of Australia. At the end of winter, approximately 36% of Australians are vitamin D deficient, in comparison to 14% at the end of summer. Therefore, making the end of winter the best time to test patients for vitamin D deficiency.
