Vitamin D Test in Glemsford

The Vitamin D test measures your 25-Hydroxyvitamin D (25(OH)D) level, the most accurate marker of your body's vitamin D status. A simple finger-prick sample is analysed on site using point-of-care technology, giving you a clear reading in approximately 8 minutes. No fasting or preparation is needed. 

Why Get Tested?

An estimated 1 in 5 UK adults have low vitamin D levels, rising to nearly 50% during winter when sunlight exposure drops. Vitamin D plays a vital role in bone health, immune function, mood regulation, and muscle strength. Left unchecked, deficiency can lead to bone weakness, increased fracture risk, persistent fatigue, and a compromised immune system.

You should consider testing if you experience unexplained tiredness, low mood or seasonal depression, frequent colds or infections, bone and back pain, or slow wound healing. Those over 65, people with darker skin tones, pregnant or breastfeeding women, and anyone who spends most of their time indoors are at higher risk.
