Learn your vitamin D level and measure inflammation in your body that may be causing discomfort

This at-home lab test can help you understand if you’re maintaining an adequate vitamin D level and check in on a marker of acute inflammation in your body.

This test measures your vitamin D (25-OH D) and high-sensitivity C-reactive protein (hs-CRP) levels

Your test results will show your levels of hs-CRP and vitamin D. Your results can help you identify lifestyle modifications that support healthy levels of these two biomarkers.


Vitamin D

Vitamin D has many important roles in the body, including bone formation and maintenance as well as immune function, among others. It forms in the body when the sun is absorbed by your skin and is found in natural and fortified food sources. Low intake levels of vitamin D over time may lead to a vitamin D deficiency.



hs-CRP, or high-sensitivity C-reactive protein, is a non-specific, acute phase protein that the liver makes in response to inflammation in the body. It may be elevated due to certain chronic illnesses, medications, or recent illnesses. hs-CRP can be used in the clinical setting as part of a broader, comprehensive assessment evaluating heart health.
