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.

Calcium Blood Test
"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

This advanced test measures 25-Hydroxyvitamin D2 and D3 along with the Vitamin D Metabolite Ratio (VMR), which includes 24,25-dihydroxyvitamin D3—a key metabolite produced when vitamin D is broken down by the enzyme CYP24A1. Assessing the VMR provides critical insight into how efficiently your body processes vitamin D, offering a deeper understanding of your vitamin D metabolism beyond standard testing.

This test is especially helpful for individuals who struggle to increase their vitamin D levels despite supplementation or those experiencing symptoms such as fatigue, low mood, weakened immunity, or poor bone health. By analysing the breakdown pathway of vitamin D, this test can highlight metabolic issues, guide more accurate dosing, and ensure you achieve the optimal concentration needed for long-term health.

Symptoms

This test assesses not only vitamin D levels but also how efficiently your body metabolises the vitamin through advanced metabolite measurement. Symptoms of poor vitamin D metabolism may include persistent deficiency despite supplementation, chronic fatigue, bone pain, low immunity, mood changes, or hormonal imbalance. It’s ideal for individuals struggling to increase vitamin D levels or those with complex health needs.

Questions

  • It measures D2, D3, and the Vitamin D Metabolite Ratio (VMR) for deeper insight into vitamin D metabolism.
  • It indicates how efficiently your body converts and breaks down vitamin D.
  • Anyone who struggles to maintain optimal vitamin D levels despite supplementation.
  • No fasting is needed for this test.
  • Every 3–6 months when adjusting vitamin D intake.

How to prepare

1. Prepare Your Kit
Wash your hands with warm water and dry them thoroughly. Lay out your kit’s contents — dried blood collection card, lancet, alcohol pad, gauze pad, bandage, and return envelope — on a clean surface. Warming your hands and shaking them gently can help increase blood flow for easier collection.

2. Collect Your Sample
Use the provided lancet to perform a quick finger prick. Allow one or more drops of blood to fall onto the designated circles on the dried blood spot card. Ensure the circles are fully saturated, but avoid touching the card with your fingers.

3. Let It Dry
Allow your blood spot sample to dry completely at room temperature before packaging. This usually takes a few minutes — do not cover or seal the card until dry.

4. Pack and Return
Once dry, place the card and all components back into the return envelope provided. Seal and mail it using the pre-paid return label. Your sample will be analysed at our specialised lab.

5. Receive Your Results
Lab analysis typically takes one week.

After the test

Once your results are ready, you can review them and discuss the findings with a qualified practitioner to interpret what they mean for your health and create an appropriate plan if needed.

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

You’ll receive results for D2, D3, and your Vitamin D Metabolite Ratio (VMR). Together, these show both your vitamin D levels and how well your body metabolises vitamin D. Low levels or an imbalanced VMR may indicate the need for dosage adjustments or further nutritional support.
