Is there any difference in your tests?

Our vitamin D tests differ from our Iron and B12 tests due to the collection method and how you receive your results. Ultimately, they each provide you with a detailed picture of your levels but use different analysis methods.

The method of sample collection differs between tests. Vitamin D test is a dried blood sample where a few drops of blood are placed on to a sample card. The Iron and B12 is a wet blood sample, where a small vial is filled with drops of blood.
