What does the Vitamin D Test measure?

The standard test measures 25(OH)D (calcidiol), the main circulating form of vitamin D that reflects overall status. The Plus test also includes 1,25(OH)₂D (calcitriol), the active hormonal form involved in calcium regulation and immune function.

What's the difference between Vitamin D and Vitamin D Plus?

The Vitamin D test includes only 25(OH)D. The Vitamin D Plus test includes both 25(OH)D and 1,25(OH)₂D, offering a more complete picture of vitamin D metabolism.

How is the sample collected?

The test uses a simple dried blood spot (DBS) method. Just a few drops from your fingertip are required.

How accurate is the test?

Your sample is analysed using LC-MS/MS, the gold standard method used in hospitals and clinical labs.

How long does it take to get results?

Results are usually available within 3–5 business days after the lab receives your sample.

Is this test suitable for vegans or vegetarians?

Yes. The test is diet-agnostic and suitable for all diets.

What’s included in the test kit?

Each kit includes a DBS card, lancet, alcohol pad, bandage, instructions, and a pre-paid return envelope. Your results include your vitamin D level with reference ranges.

Where is my Vitamin D Test analysed?

Samples from the Asia-Pacific region, including Australia and New Zealand, are analysed in our accredited laboratory in Australia. Samples from Europe and the United Kingdom are processed in our certified EU laboratory, ensuring all results meet international clinical standards for accuracy and reliability.

Description
What does it include?

The Vitamin D Blood Test measures total 25-hydroxyvitamin D (25(OH)D) to assess overall vitamin D status using a simple at-home dried blood spot sample.

Vitamin D plays a central role in calcium regulation, bone metabolism, immune function, muscle performance, and endocrine balance. It acts as a hormone precursor that influences numerous biological processes throughout the body. Despite adequate sunlight exposure in some regions, vitamin D deficiency remains common worldwide.

The Vitamin D Blood Test provides an accurate assessment of total 25(OH)D, the primary circulating form used to evaluate vitamin D status. Suboptimal levels may be associated with reduced immune resilience, impaired bone density, muscle weakness, and increased cardiometabolic risk.

Monitoring vitamin D levels is particularly important for individuals focused on immune optimisation, longevity strategies, athletic performance, bone health, or those with limited sun exposure. It may also support evidence-based supplementation decisions to maintain optimal serum levels.

All samples from the Vitamin D Blood Test are analysed in certified laboratories and include clear reference ranges to support informed and proactive health management.

The Test contains: Dried Blood Collection Card, Lancet, Alcohol Pad, Bandage, Gauze Pad and Pre-Paid return envelope.
