VitaminD3Word now offers a diagnostic kit from ZRT labs so that you can test your Vitamin D levels in the convenience of your own home, anywhere in the world. This test measures calcidiol 25 (OH) D levels, which is the storage form of Vitamin D. 25(OH) levels, truly reflect your Vitamin D status. Many tests measure total Vitamin D status which is not helpful.
