Using a competitive binding method, it provides clear visual results with a color guide, empowering proactive health management without the hassle of lab visits. ## Description WHAT IT TESTS: This test checks the level of 25-hydroxyvitamin D (25 (OH) D) in your blood. It helps assess your Vitamin D status, which is vital for various aspects of your health EASY SELF-TESTING: You can easily perform this test at home. It's designed for self-testing and gives you a preliminary result without needing a visit to the lab VITAMIN D IMPORTANCE: Vitamin D is essential for your body as it helps with the absorption of calcium, iron, magnesium, and more. It's necessary for bone health, immune function, and overall well-being HEALTH IMPLICATIONS: A deficiency in Vitamin D can lead to various health issues such as osteoporosis, cardiovascular diseases, and even depression. Knowing your Vitamin D status can help you take steps to maintain good health HOW IT WORKS: The test uses a simple principle of competitive binding. The result is indicated by the test line's darkness. The included colour card helps you interpret the result, and a control line ensures the test was done correctly Review: Easy to use - As it's so difficult to get in for a blood test at our GP, we tend to purchase these in order to keep an eye on Vit D levels. Don't give you a percentage but they tell you what your range is, i.e whether you're deficient or okay. Not as cheap or accurate as doctors but next best thing. Review: Very nicely presented - Well made, good value and easy to use but, as with all these types of at home kits, there is no way of knowing how accurate it really is. If I can persuade my GP to give me a test then I would have a reference point, but until then it's really just a rough guide I think. ## Features - WHAT IT TESTS: This test checks the level of 25-hydroxyvitamin D (25 (OH) D) in your blood.

It said I was in normal range but after the doctors blood test I was extremely deficient. In my opinion a waste of money! **Q: what exactly are these tests testing ? -it should be testing total vit d ( d2 and d3 )which I doubt very much these quick tests can possibly do** A: It tests whether you're Deficient <10ng/mL Insufficient 10-30ng/mL and Sufficient, >30-100ng/mL. (< means less than or equal to) (> means greater than or equal to) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use *by J***Y on 19 November 2023* As it's so difficult to get in for a blood test at our GP, we tend to purchase these in order to keep an eye on Vit D levels. Don't give you a percentage but they tell you what your range is, i.e whether you're deficient or okay. Not as cheap or accurate as doctors but next best thing. ### ⭐⭐⭐⭐ Very nicely presented *by S***E on 29 September 2024* Well made, good value and easy to use but, as with all these types of at home kits, there is no way of knowing how accurate it really is. If I can persuade my GP to give me a test then I would have a reference point, but until then it's really just a rough guide I think. ### ⭐ Book a blood test with your GP... *by M***N on 27 September 2020* I bought this kit over a month ago when I was experiencing very bad hair loss and had experienced cardiac problems, which can all be as a results of low vitamin D. I had been booked into my GP urgently, after waking up with symptoms of a possible oncoming heart attack. Having been tested for the more obvious imbalances including full blood count/iron levels, having an ECG and hospital referral and being told everything was OK, that my iron levels were "borderline" but I wasn't anaemic, I thought there was something that wasn't right. I googled online (as I was severely anaemic 4 years ago and had never experienced the extreme chest pains and other symptoms then) and discovered that Vitamin D can cause cardiac events and hair loss too, so I started taking Vitamin D, and ordered 2 of these tests. I used one and I found it very difficult to read the results due to the pink tones on the test result barely differing. From the results, it looked as though I was not deficient in Vitamin D. Fast forward to this week just gone. I decided, after a little while to ask my GP if I could be tested for Vitamin D, as I was losing my hair a lot still but not as severely as before I started taking Vitamin D tablets, and thought it best to get it officially tested. My vitamin D levels came back extremely low. While these tests can feel like a comfort to have to hand, this demonstrates the results weren't reliable. If in doubt, always go to your GP and ask for a blood test. It can be dangerous to rely on a home test. There is also very recent research indicating that low vitamin D levels can lead to anaemia too, so if your ferritin/iron levels are lower than they should be and you can't logically understand why (if diet has been consistent) then there is a possibility your Vitamin D levels may be low. I personaly now would not rely on these tests. It may just be that the test I used didn't perform as well as other peoples though. There is always that possibility. ## Frequently Bought Together - 2 x Vitamin D Level Insufficiency Deficiency Testing Kits (2 Tests) - Anaemia Test Kit Iron Deficiency Ferritin Testing Blood Anemia Test One Step (1 Test) - Underactive Thyroid Testing Kit, TSH Blood Tests for Hypothyroidism One Step (1 Test) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/60827408-2-x-vitamin-d-level-insufficiency-deficiency-testing-kits-2](https://www.desertcart.be/products/60827408-2-x-vitamin-d-level-insufficiency-deficiency-testing-kits-2) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-28*
