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 — the gold-standard reference method used by hospital pathology labs. Our method has been clinically validated against the DEQAS-certified serum reference method: 96.9% sensitivity, 97.2% specificity, 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.
Vitamin D Test is operated in Australia by Masdiag Pty Ltd. This product is intended for general informational use and is not a substitute for clinical advice from a qualified healthcare professional.
The test was easy to administer and there was an efficient turnaround from posting, to being notified that it had arrived at its destination, and then to the final results. I am looking forward to the re-test in three months and seeing what impact taking the supplements AND increasing my vitamin D through diet in a conscious way will have on my results. Very happy with the product and service.
