How does ZRT Labs test Vitamin D levels?
You simply perform the blood collection at home and send it in the pre-paid return package to the ZRT laboratory where it is tested by a professional lab technician.
Once ZRT Labs 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.
