The value
Why it's worth knowing
Both forms of vitamin D, not just one
25-OH Vitamin D (the storage form) and 1,25-OH Vitamin D (the active form) measured together, the only way to see your true vitamin D status. Most routine vitamin D checks only measure one form.
Parathyroid hormone (PTH) included
PTH rises when calcium is low, the marker that reveals whether your body is silently pulling calcium from bone to compensate, often the earliest sign of long-term vitamin D deficiency.
The mood, immunity and energy connection
Vitamin D acts more like a hormone than a vitamin, shaping mood, immune function and energy. A driver behind winter blues, recurring colds and inexplicable fatigue, especially in Australians who work indoors.
The magnesium and calcium picture
Vitamin D cannot work properly without magnesium, and calcium balance depends on both. All three measured together for the full read.
Optimise, do not just pass the lab range
Australian “normal” ranges are set to prevent deficiency, not to optimise health. Many sit inside the range yet well below the levels linked to better energy, immunity and bone health.
The deficiency one in four Australians carry silently
Vitamin D deficiency is one of the most common nutrient issues in Australia, often only noticed when bones, mood, immunity or hormones start to slide.

FAQs
Common questions
Everything you need to know before you order.
Through your GP, blood tests are typically only covered by Medicare when they're medically warranted. Medicare covers testing because a condition justifies it, not because you want to be proactive or just want to know certain things. You can't just walk in and ask for a panel of biomarkers because you're curious or want a baseline. Your doctor decides which markers get tested, and that list is usually limited.
MediTests is for people who want to take a proactive approach to their health. Deep insights, a personal baseline, and the exact markers you want to track over time. You're in full control. It's your data. No condition required, no waiting room, no eligibility hurdles.
You can get any test you want, with over 300 blood tests across 16 categories. We never refuse a blood test.
You also get your original lab report back in 24 to 48 hours, sent straight to your inbox. No follow-up consult, no appointment to book, and nothing linked to My Health Record or Medicare. Completely private.
Same NATA-accredited labs GPs and hospitals use. Same accuracy. None of the waiting.
No GP consult or telehealth appointment needed. We instantly generate your pathology request form and send it directly to your inbox after checkout.
If you would like one, we also offer private doctor consultations as an optional extra, for people who want private blood test results and a private consult to discuss them.
As simple as it gets:
Choose your test online. Your pathology request form arrives in your inbox instantly.
Walk into any of our 3,300+ collection centres. No appointment needed.
Results delivered securely to your inbox in 24 to 48 hours.
Most tests need no fasting at all. Some markers, like fasting glucose, fasting insulin and certain cholesterol panels, give the most accurate reading after fasting. If your test needs it, it's stated on the product page and on your pathology request form. Water is always fine.
No, never. Nothing is linked to My Health Record or Medicare. Your results are completely private and confidential: they're sent securely to your email, and only you decide who sees them. Many of our customers choose MediTests for exactly this reason, and we take that privacy seriously.
100%. We partner with NATA-accredited Australian laboratories, the same trusted labs used by hospitals and GPs across the country. Every result is processed to the same clinical standards as your local pathology centre.
Never. The price you see includes everything: your pathology request form, testing, processing and results. No surprises.
The most common reason is that something feels off but a standard GP panel hasn't turned anything up. Fatigue, brain fog, weight gain, low mood, poor recovery, irregular cycles and low libido all have measurable biological causes that a targeted panel can identify.
You don't need symptoms to benefit from testing. Proactive testing establishes your personal baseline, catches risk factors before they cause harm, and helps you understand whether diet, training or lifestyle changes are actually working.
Yes, absolutely. You can build your own panel by choosing from our wide range of individual tests. Whether you're checking one thing or a combination of markers, you're in control of what you get tested for. Visit our Create Your Own Test page to start building.

A very positive experience
I booked a blood test because my health insurance did not cover GP consultations. The referral form was emailed to me immediately, I walked into a collection centre the next morning and my results arrived the very next day. One result showed an elevated TSH level and because I was pregnant, a doctor from their Sydney office personally called me to talk it through. It made me feel they genuinely cared.

Could not have been better
I've been in remission from Graves Disease for a few years and suddenly had symptoms again. It was easy to choose and purchase the test I needed at a reasonable price and set up the appointment online for the next day. The lab tech was friendly and put me entirely at ease, and the results were delivered electronically within a day or two. Could not have been better.

I selected and ordered the tests I wanted online, then dropped into the clinic for the blood draw during my lunch break. The process was quick and efficient, and by lunchtime the following day my results had been emailed directly to me. Fast, convenient and hassle-free.

Vitamin D Optimisation Panel
The Vitamin D Optimisation Panel is a vitamin D blood test that goes well beyond a single reading. It is built for people who want to properly understand and optimise their vitamin D status, particularly given how common deficiency is across Australia despite the climate.
It measures both 25-OH vitamin D (the standard storage marker) and 1,25-OH vitamin D (the active hormonal form), alongside parathyroid hormone (PTH), calcium, magnesium and phosphate. Testing the active form and PTH together gives insight a standard vitamin D test cannot, showing how well your body is actually using and regulating vitamin D, not just how much is stored.
Vitamin D plays a role in bone health, immunity and mood, and Healthdirect Australia notes deficiency is widespread despite the sunshine. The Vitamin D Optimisation Panel needs no GP referral and no appointment, so you can get your blood test online and walk into any of 3,300+ collection centres across Australia, with results in 24 to 48 hours.
What we test for
25-OH Vitamin D The standard measure of vitamin D in the body. Reflects both sun exposure and supplementation and is used to assess whether levels are deficient, insufficient or within a healthy range.
Parathyroid Hormone (PTH) Produced by four small glands in the neck, PTH regulates calcium and phosphate levels in the blood. Chronically low vitamin D causes PTH to rise, which over time draws calcium from bone to compensate. Elevated PTH alongside low vitamin D is a key indicator that deficiency has been present long enough to affect bone metabolism.
Calcium (Serum) The primary mineral in bone and teeth, calcium is also essential for muscle contraction, nerve signalling and heart function. Serum calcium is tightly regulated by PTH and vitamin D — abnormal levels can indicate absorption problems or underlying metabolic issues.
Magnesium (Serum) Magnesium is required for vitamin D to be converted into its active form in the body. Low magnesium means vitamin D supplementation may have limited effect, regardless of dose. It also plays a direct role in bone density, muscle function and sleep quality.
Phosphate Works alongside calcium in the structure of bone. Imbalances in phosphate can indicate kidney dysfunction, malabsorption or parathyroid problems, all of which affect how well the body manages vitamin D and calcium together.
1,25-OH Vitamin D (Active Form)(optional add-on) The biologically active form of vitamin D produced by the kidneys. While 25-OH vitamin D reflects your stores, 1,25-OH tells you how much active vitamin D your body is actually producing and using. Useful when standard vitamin D appears normal but symptoms persist, or when kidney or granulomatous conditions are suspected.
