Vitamin D Test

Vitamin D is widely under-monitored despite being one of the most common deficiencies in central European populations, particularly through the winter months when sunlight-driven skin synthesis is limited. The test measures 25-hydroxyvitamin D, the circulating storage form that best reflects overall vitamin D status. Adequate vitamin D supports calcium absorption and bone mineralisation and is associated with immune and muscular function. MZ-Biochem offers the test on a self-pay basis without a referral, making it straightforward to check status before starting supplementation and to confirm that a supplement dose has restored levels into the desired range. No special preparation is required. Results are best reviewed with a physician, who can advise on supplementation and any retesting.
