VITAMIN D2

The VITAMIN D2 test measures the circulating level of 25-hydroxyvitamin D2 (25‑OH D2), the primary metabolite used to evaluate vitamin D2 status in the body. Performed on a small blood sample collected at home and analysed in an accredited laboratory (often by immunoassay or LC‑MS/MS), it helps assess whether ergocalciferol supplementation or sun exposure is maintaining adequate levels for bone and immune health.

This test is useful for baseline assessment and monitoring of patients taking vitamin D2 supplements, and for people at higher risk of deficiency—such as older adults, individuals with limited sun exposure (including those observing traditional clothing practices in Dubai), people with darker skin, obesity, malabsorption syndromes or certain chronic illnesses. Results typically include laboratory reference ranges, clinical interpretation and personalised recommendations to guide supplementation, diet and follow‑up with a healthcare provider in the UAE.

• 25‑Hydroxyvitamin D2 (25‑OH D2)

• Vitamin D2 concentration (nmol/L)
• Reference range categories (Deficient / Insufficient / Sufficient)

• Symptoms of deficiency: bone pain, muscle weakness or frequent fractures
• Before or during vitamin D2 supplementation to monitor response
• Limited sun exposure (indoor lifestyle, extensive clothing coverage)
• Known malabsorption, bariatric surgery or chronic gastrointestinal disease
• Age-related risk: elderly patients or those with osteoporosis

• Accurate analysis by accredited UAE laboratories
• Convenient at‑home blood collection with fast result delivery
• Clear interpretation with reference ranges and clinical context
• Personalised recommendations to optimise bone health and immunity
• Useful for monitoring effectiveness of vitamin D2 therapy

• At‑home blood sample collection (finger‑prick or venous) by a trained phlebotomist
• No fasting required prior to the test
• Inform the phlebotomist of all medications and vitamin D supplements; consult your physician before pausing therapy
