Researchers Develop Rapid, Reliable Vitamin D Test

In developing this new test, Professor Philip Britz-McKibbin and his colleagues recognized there was a need for a cost-effective and rapid way to assess vitamin D status from a blood sample. Their method was developed with the goal identifying vitamin D deficiency in critically ill children, who would likely benefit from vitamin D supplementation.

In the future, however, researchers envision that home testing could eventually be performed using just a finger pinprick of blood, thus supporting the concept of a personalized health approach and helping ensure optimal vitamin D status in individuals. Such an approach would have the benefit of empowering people to take greater control over their health.
