Vitamin D is a fat soluble vitamin that serves many functions in the body essential to overall health. Vitamin D enhances the absorption of calcium to promote bone remineralization and remodeling, plays a role in neuromuscular function, modulates the immune system to prevent infection and autoimmune diseases, and enhances the release and action of insulin. Symptoms of Vitamin D3 deficiency may include chronic low back pain, body aches and pains, fatigue, bone pain, and dental abnormalities.
The testing Wellnicity offers utilizes blood microsampling technology which is capillary blood. This blood source is rich with nutrients, hormones and oxygen to feed tissues. Venous blood (that which is taken at a laboratory) is lacking nutrients because it is returning to the gastrointestinal tract, lungs and heart to pick up another load for distribution. As such, your levels on this test may vary from levels obtained via blood draw. The percent variability from venous to dried blood microsampling technology is around 15-20%. Please keep in mind though, that the variability is from the SAME methodology on the SAME instrument with the SAME reagent lots drawn at the SAME time. The method used to analyze samples at our lab is HPLC-MS.
