Two complete Vitamin D tests for $107.90 — just $53.95 per kit. Save $12. The clinically-recommended way to use a vitamin D test is to measure your level, change something (sunlight, supplementation), then retest in three months to see what worked. This twin pack gives you both — a baseline now, a follow-up later — for less than two singles. Or share it with someone you love. Each kit is individually packaged with its own collection card, lancet, plaster, and reply-paid envelope. Two people, two private results. What's included (×2): Two complete at-home collection kits — each individually sealed Two reply-paid envelopes for free returns Two separate personalised reports delivered to your email How most people use it: Baseline + 3-month retest — take the first test now, retest in 3 months after starting (or adjusting) supplementation to see how your level has changed. Share with someone you love — partner, parent, sibling. Each result is private and emailed separately. The same gold-standard analysis as our single test: Measures 25(OH)D (the marker your GP would order) using LC-MS/MS — the reference method Analysed in an accredited Australian laboratory Class IIa TGA-registered collection kit (ARTG 526367) Personalised report including supplementation guidance and when to retest Free Australia-wide shipping both ways An accessibly-priced lab-grade vitamin D test — at $53.95 per kit.
