Vitamin D Test

A single-marker test measuring 25-hydroxyvitamin D (25-OH vitamin D), the standard blood marker of overall vitamin D status. Vitamin D is associated with bone health, calcium absorption and immune function, and deficiency is common in the Central European winter. A quick, low-cost check that is easy to repeat. Measured at the ISO 15189-accredited Brno-Starý Lískovec laboratory, results usually within 24 hours.

Vitamín D is a single-marker self-pay test that measures 25-hydroxyvitamin D (25-OH vitamin D), the metabolite used as the standard indicator of a person's overall vitamin D status. It is preferred to other forms of vitamin D because it circulates at higher concentrations and has a longer half-life, giving a stable read of stores built up from sunlight exposure, diet and supplements over the preceding weeks. Vitamin D is associated with bone health and calcium absorption, with normal muscle function, and with immune regulation, and a low level is one of the most common findings in the Central European population — particularly through the low-sunlight months from autumn to spring. The test suits people who spend little time outdoors, follow restrictive diets, are managing bone health (it pairs naturally with the Osteoporosis bone-turnover panel), or simply want to confirm whether a supplement dose is achieving an adequate level. The sample is a single venous blood draw of around fifteen minutes, taken on a walk-in basis between 07:00 and 11:00, Monday to Friday, at the second-floor collection room of the Poliklinika U Pošty in Brno-Starý Lískovec. No special fasting is generally required for vitamin D, but confirm collection conditions when booking. All sampling material is provided free of charge. Lab Med periodically offers this test at a reduced sale price of 425 Kč against the standard 502 Kč. Results are typically released within 24 hours, collected in person against signature and ID or via secure electronic delivery arranged at the collection room. Because vitamin D status shifts seasonally, repeat testing — for example at the end of winter and again after summer, or a few weeks after starting supplementation — is often more informative than a single reading. A low result and any decision about supplement dosing are best discussed with a physician, especially for people with kidney disease or conditions affecting calcium. The analysis is performed under ČSN EN ISO 15189 accreditation.
