Vitamin D testing at Home

Why test Vitamin D? Vitamin D deficiency is very common, particularly in northern climates with little sunshine. Vitamin D has been found to be important in protecting the body from a wide range of diseases, including cardiovascular disease, stroke, osteoporosis, osteomalacia, cancer, autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, diabetes (types 1 and 2), and schizophrenia.

Until now, venipuncture blood serum has been the standard medium for testing Vitamin D. To overcome the issues of inconvenience to the patient and practitioner, our new kit was developed and refined for Vitamin D testing with blood spots. A few drops of blood from a quick and nearly painless nick of the finger, placed on a filter paper to dry are all that is needed. This can be done at home, meaning no more painful venous needle sticks or the inconvenience of driving to a blood collection center.

How does the new blood spot Vitamin D assay compare with conventional venipuncture serum testing? This test method by liquid chromatography/tandem mass spectrometry (LC-MS/MS) has shown conclusively that this new blood spot testing method is quantitatively equivalent to conventional serum Vitamin D testing by LC-MS/MS.

The test kit can be purchased here. It will be sent to your home with instructions. Once you add your drops of blood to the provided test paper you send it to the lab with a mailer that is provided free of charge. The only shipping cost you will incur is the first shipping to you which will be $5.00.

If you would like to set up an appointment time to talk with Dr. Simpson about your results and what to do about them, go to this page.

This test is one of the most informative and important health test you will ever take!!!
