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.
