Product Review

The ZRT Vitamin D Deficiency Blood Spot Test screens Vitamin D levels and detects Vitamin D deficiency through a simple procedure. Once ZRT receives your dried blood spot sample, you will be able to obtain your results in about a week. As you continue to monitor your Vitamin D levels, ZRT will generate a "history" test report comparing your latest test results to previous results. If Vitamin D supplementation is necessary, this history report will track the effectiveness of your treatment and help your health care provider recommend the right supplement dose.
