Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

"I'm a little biased as I work here! However, I love that The Bloody Good Test tracks my health over time. After turning 40, I wanted to make sure I wasn't going to drop dead from something basic I should have known about earlier. Measuring all my core biomarkers each year gives me peace of mind my health is on the right track"

Overview

Vitamin D is much more than just a vitamin - it's actually a powerful hormone that acts like your body's master conductor, orchestrating everything from bone strength to immune defense. While your skin naturally produces vitamin D when exposed to sunlight, modern life often keeps us indoors, and even in sunny Australia, deficiency is surprisingly common due to sunscreen use, office jobs, and seasonal changes.

This essential hormone works behind the scenes in remarkable ways: it unlocks your body's ability to absorb calcium for strong bones, fine-tunes your immune system to fight infections while keeping it from attacking healthy tissues, supports muscle strength and function, and even influences your mood and brain health. When your vitamin D levels are too low, you might experience fatigue, frequent infections, bone pain, or mood changes - your body's way of signaling that this crucial conductor is missing from the orchestra. Testing your vitamin D levels gives you valuable insight into whether your body has enough of this master regulator to keep all your systems performing in harmony.

Symptoms

Essential for everyone, particularly those with limited sun exposure, office workers, people with darker skin, elderly individuals, and those living in southern Australia. Important for people experiencing frequent infections, mood changes, bone pain, muscle weakness, or fatigue. Valuable for monitoring supplementation effectiveness and optimizing immune function.

Questions

  • In summer, 5-15 minutes of midday sun exposure to arms and face several times per week is usually sufficient for fair-skinned individuals. Darker skin requires longer exposure. Winter sun in southern Australia is often insufficient.
  • It's difficult to get adequate vitamin D from food alone. Fatty fish, eggs, and fortified foods help, but supplements are often necessary, especially in winter or with limited sun exposure.
  • Vitamin D3 (cholecalciferol) is more effective at raising and maintaining blood levels than vitamin D2 (ergocalciferol). Most supplements and recommendations focus on D3.
  • With appropriate supplementation, levels typically improve within 6-12 weeks, though it may take 3-6 months to reach optimal levels depending on starting point and dose.
  • Yes, excessive supplementation can lead to toxicity, causing nausea, kidney problems, and calcium buildup. However, toxicity is rare and usually requires very high doses over extended periods.
  • For most people, annual testing is sufficient. More frequent testing may be needed when starting supplementation, during treatment for deficiency, or if you have conditions affecting absorption.

How to prepare

No fasting required. No special preparation needed. Can be taken at any time of day. If taking vitamin D supplements, maintain your usual routine unless specifically advised otherwise by your healthcare provider. Biotin supplements should be avoided for 3 days before testing.

After the test

If levels are low, discuss appropriate supplementation with your healthcare provider. Typical recommendations include vitamin D3 (cholecalciferol) supplements, safe sun exposure, and dietary sources. Dosing depends on current levels, body weight, and individual factors. Retest in 3-6 months to monitor response to supplementation. Severe deficiency may require prescription-strength doses initially.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Optimal levels: 75-150 nmol/L (30-60 ng/mL). Deficient: <50 nmol/L (<20 ng/mL); Insufficient: 50-74 nmol/L (20-29 ng/mL); Sufficient: ≥75 nmol/L (≥30 ng/mL). Toxicity rare but possible above 375 nmol/L (150 ng/mL). Many health experts recommend maintaining levels above 100 nmol/L (40 ng/mL) for optimal health benefits.

If your test needs fasting, we’ll include that in your instructions after you order. Fasting usually means no food for 8–12 hours, but water is fine.
