A self-pay 25-OH vitamin D blood test at the Zlín poliklinika collection point. 25-hydroxyvitamin D is the main storage form measured to assess whether vitamin D levels are adequate — relevant to bone health, calcium metabolism, immunity and energy, and commonly low in the Czech climate, especially in spring. No referral required; payment is made at the draw.

About this treatment

Vitamin D exists in the blood in two forms: 25-hydroxyvitamin D (calcidiol), the main inactive storage form, and 1,25-dihydroxyvitamin D, the active form. Because of its longer half-life and higher concentration, 25-OH vitamin D is the marker used to assess and monitor a person's vitamin D status. Vitamin D comes both from the skin's response to sunlight and from food and supplements, and a large share of the population in this climate runs low,…

Why it is measured

25-OH vitamin D testing is used to check whether a deficiency (or, less often, an excess) is affecting bone formation or calcium metabolism, to monitor people whose conditions impair fat absorption, and to assess the effect of vitamin D supplementation. Adequate vitamin D supports calcium absorption and bone strength, immune defence, muscle function and mood.
