Vitamin D Blood Spot Test

Vitamin D deficiency (levels measured below 32 ng/ml) does not have obvious symptoms and can increase your risk for more serious diseases including flu, cardiovascular disease, osteoporosis and multiple sclerosis. In addition, an increased risk for strokes, diabetes (types 1 and 2), depression, and breast and colon cancer are closely linked to low Vitamin D levels.

ZRT Laboratory has been offering dried blood spot testing for over 15 years, and all tests that could be done in either blood spot or serum are thoroughly validated against serum testing to demonstrate analytical equivalence.

Dried blood spots can be collected right in the patient’s home, preventing exposure for themselves and the public. That’s right – patients get to skip the waiting room and the visit to the laboratory facility, which they have to do for traditional blood draw tests. Our accurate and reliable dried blood spot testing serves as the ideal means for measuring analytes such as insulin, blood lipids, Vitamin D, thyroid hormones, sex hormones, and elements like lead and magnesium – all from the comfort of your patient’s home.
