Vitamin D Plus Blood Test Kit (25(OH)D + VMR)

Your vitamin D level — and how well your body actually uses it.

How your sample is measured

Lab-analysed by LC-MS/MS, the reference method. Many vitamin D tests don't say how they're measured; we do. A 10-minute rapid strip shows a colour band or range; this kit gives you a measured 25(OH)D number from the laboratory.

Class IIa TGA-registered collection kit (ARTG 526367)

The Vitamin D Plus test measures both your circulating vitamin D (25(OH)D) and your Vitamin D Metabolite Ratio (VMR) — a more advanced marker that reveals how efficiently your body is metabolising vitamin D. Two people with identical vitamin D levels can have very different VMRs. The standard test alone can't tell you this. 

What you get

• 25(OH)D level — your circulating vitamin D in ng/mL, with nmol/L also shown on your report, measured against clinical reference ranges
• Vitamin D Metabolite Ratio (VMR) — how effectively your body metabolises vitamin D
• Personalised plain-English interpretation of your results
• Trend tracking across repeat tests, so you can see what's working
• Downloadable PDF report you can keep or take to your GP

What's in the box

• Dried Blood Spot (DBS) collection card
• 2 × lancets
• Alcohol wipe
• Gauze pad
• Step-by-step instructions for use
• Reply-paid return envelope

How it works

Order your kit (free Australia-wide shipping), collect a small finger-prick sample at home onto the dried blood spot card (takes 2 minutes), drop the reply-paid envelope into any Australia Post box, and read your full report online within 3–5 working days of the lab receiving your sample.

The science

Your sample is analysed by ID LC-MS/MS — Isotope-Dilution Liquid Chromatography Tandem Mass Spectrometry with C-3 epimer separation. The reference method used by hospital pathology labs, not the cheaper immunoassays most home tests use.

Our method has been clinically validated against the DEQAS-certified serum reference method: R² 0.97 correlation between finger-prick and venous draw.

No GP referral required

Order, collect, and receive your results without ever stepping into a clinic. We always recommend discussing clinically significant results with your doctor.

Lab blood test vs 10-minute rapid test

Frequently asked questions

Do I need a GP referral?

No. You order online and collect the sample yourself.

Is a finger-prick test as accurate as a blood draw?

When the dried blood spot is analysed by LC-MS/MS in an accredited lab, results correlate closely with venous serum (R² 0.97 in our validation). Rapid strip tests are a different, less precise technology.

How is this different from a 10-minute rapid test from a chemist?

A rapid cassette gives a colour band or range in about 10 minutes. This kit gives a measured 25(OH)D number from an accredited laboratory using LC-MS/MS, with results in 3–5 business days from lab receipt. See the comparison table above.

Is it covered by Medicare?

No. Medicare rebates vitamin D blood tests (MBS item 66833) only when specific clinical criteria are met. This kit is self-funded.

Do I need to fast?

No. Vitamin D status doesn't change meaningfully with a meal.

What is a normal vitamin D level in Australia?

Australian guidance generally treats 50 nmol/L (about 20 ng/mL) or above (at the end of winter) as adequate. Your report shows where you sit.

How soon can I retest?

After a change in routine or sun exposure, about 3 months is a sensible interval.
