About the Vitamin D (25-OH) (Venous)
The Vitamin D (25-OH) (Venous) is an individual blood test offered at our private clinic in London. A venous blood is collected by a registered nurse during an appointment lasting approximately 20 minutes. Results are typically available within 1 day" and are delivered securely via email.
Vitamin D is a fat-soluble vitamin that the body produces when the skin is exposed to sunlight. It plays an essential role in calcium absorption, bone mineralisation, immune regulation, and muscle function. The 25-hydroxyvitamin D (25-OH) blood test is the standard method used to assess vitamin D status. In the UK, limited sunlight exposure, particularly during autumn and winter months, means that vitamin D insufficiency is relatively common. Public Health England notes that around 1 in 5 people in the UK may have low vitamin D levels. Testing provides a measured value that can be compared against established reference ranges.
Who May Consider This Test
The Vitamin D (25-OH) (Venous) may be relevant for a range of individuals. The following are common reasons people choose to have this test:
- Individuals with limited sun exposure or who spend most time indoors
- People living in northern latitudes such as the UK
- Those experiencing bone or muscle discomfort
- Individuals with darker skin tones, who synthesise vitamin D less efficiently
- People over 65, as the skin becomes less efficient at producing vitamin D
- Anyone following a restricted diet low in vitamin D-rich foods
