Minerals and their function

Minerals are essential for maintaining good health. They fulfil a wide array of functions in the body such as building materials for the strong bones and muscles. Minerals are incorporated in several metabolic pathways to ensure the normal function of cells.

Some minerals function as building-blocks, others as regulators in the body, and others as immune system boosters.

Among these immune system boosters are the minerals Magnesium, Zinc and Selenium. These are the minerals that are tested with the blood test from Gettested. 


Magnesium contributes to healthy muscles, strong teeth and bones. It is not made by the body, which is why you must eat foods that contain magnesium. Not only does magnesium give your body extra energy, it also helps you to stay in a good mood. If you take magnesium an hour before you go to bed, it will help you relax and get a good night’s sleep. Magnesium is also essential for muscle contraction and its deficiency leads to physical and mental weakness as well as hyporeflexia (the reduction or absence of normal bodily reflections). There are many foods that contain magnesium as well as magnesium supplements.


Zinc is an antioxidant. It is crucial for the immune system to produce B- and T-cells. Besides supporting the immune system, Zinc is essential for wound healing and helps treat diarrhoea. This mineral also enables the body to make DNA and proteins. Many foods contain Zinc. 

Research also indicates that Zinc is essential to male sexual health. Because Zinc plays an important role in bone health, it may be helpful in preventing osteoporosis. Much research has been done in the area of Zinc, and though some research is still suggestive, it can be said that Zinc is vital to the body and it comes with many health benefits. 


Selenium is an essential mineral that can not be produced by the body. It can be found in many foods naturally. Selenium helps to make DNA and it protects the red blood cells against infections and can help boost the white blood cells. Selenium also promotes thyroid function, responsible for producing and releasing hormones. Additionally, it is linked to reproductive health. 

Further research on the relationship between selenium and cancer has shown that people with low levels of selenium had a higher risk of developing cancer.

Before taking the test

  • Your test ID must be registered before it is sent for analysis (otherwise the lab will not analyze the test).
  • We recommend that you take the test on an empty stomach in the morning.
  • We recommend that you submit the test for analysis on a Monday or Tuesday.
  • If tracking code is available, please attach it to the front of the envelope (found on your test ID card).
  • Before you start, you need to register your test. Your test kit contains a sticker with your unique test ID. Register your test ID at my.gettested.io.
  • Wash your hands in hot water for about a minute. This will increase blood circulation in your fingers. Dry your hands. Doing a blood test without stimulating blood circulation might prove difficult, so please do not skip this step.
  • Disinfect your “test finger” with the supplied disinfectant paper. Wait a few seconds until the finger is completely dry.
  • Rotate the protective cover on the blood lancet to remove it. Use the extra lancet if you need to do another finger prick.
  • Place your hand on a flat surface. Put the lancet diagonally toward the test finger and press down the button. Make sure the lancet is pressed against the finger the whole time.
  • We recommend that you stand up at this stage to let the blood in your arm flow downward. Help the blood drops come out by massaging the finger toward the needle stick.
  • Transfer the blood drops into the test tube until the blood reaches the marked line. If it doesn’t reach the marked line, there won’t be enough blood for the lab to test. Please contact us if you have any trouble.
  • Place the sticker with your unique test ID on the test tube. Place the test tube inside the transport tube and seal.
  • Put the tubes in the enclosed envelope and send it to the lab the same day, preferably a Monday or Tuesday.

    Got this as a christmas gift 🙂 So easy to use, results came in fast which I’m grateful for. Looks like I need more magnesium in my diet. Was nice to do it from home!

  2. Mrs. Mia

    For the past few months, I’ve been dealing with hair loss and it’s been really worrying. I wasn’t sure what was causing it, so I started doing some research and found out that certain mineral deficiencies could be a contributing factor.Fpund this test and thought it was worth a try. The process was simpler than I expected. The instructions were clear and straightforward, which made taking the test a breeze. I sent it off and awaited the results.

    To my surprise, the results came back quicker than I thought. They showed that I had a deficiency in selenium, a mineral known to be important for hair health. While it was a bit disconcerting to discover this, it also provided a sense of relief. It gave me an actionable insight that I could take to my doctor and discuss potential solutions.

    This test not only helped me understand a possible reason behind my hair loss but also shed light on an aspect of my health that I hadn’t considered before. It has prompted me to pay more attention to my mineral intake, not just for my hair health, but for my overall well-being.

  3. Aiden O’Brien

    Used this test. Discovered a zinc deficiency. Prompt results. Had trouble doing the test but I got help and a new kit so I could redo it. 🙂

    In today’s fast-paced world, cutting corners on nutrition seems almost inevitable. Despite my best efforts, I couldn’t shake off the nagging feeling that my body was missing out on essential nutrients. The Mineral Deficiency Test promised clarity, and it did not disappoint. From the outset, the entire process was hassle-free. The kit was thoughtfully designed, ensuring that even the least tech-savvy individual could navigate it effortlessly. But where the test truly shines is in its comprehensive report. Receiving a breakdown of mineral levels was expected. What wasn’t anticipated was the depth of insights provided. The report didn’t just highlight deficiencies; it painted a vivid picture of the role each mineral plays, the symptoms of imbalance, and actionable recommendations on addressing any gaps. :))))))Since adapting my diet based on the results, the transformation in my health has been profound. I’m more focused, my sleep has improved, and the constant fatigue that once plagued me is now a distant memory. This test was the cornerstone of my newfound vitality, and I cannot sing its praises loudly enough.

    Navigating the maze of health and wellness can often feel overwhelming, especially when inundated with conflicting information from the internet, friends, and even health professionals. It became clear to me that understanding my body’s unique needs was a prerequisite to genuine health. This realization led me to the Mineral Deficiency Test. Upon receiving the test kit, the first thing that struck me was its simplicity. Each component was designed with the user in mind, making the collection process smooth and stress-free. The guide provided clear, step-by-step instructions, ensuring that even someone as technically challenged as myself could complete it with ease. What followed, however, was truly the highlight of my experience. The detailed analysis report was nothing short of a revelation. Instead of merely listing my mineral levels, it delved deep into understanding the significance of each mineral, the potential consequences of deficiencies, and tangible steps to rectify imbalances. Armed with this information, I felt empowered to make informed decisions regarding my nutrition and supplement intake. The difference has been night and day. Not only do I feel more energized and alert, but I also notice improvements in my skin, hair, and overall well-being. The Mineral Deficiency Test was a pivotal step in my journey to optimal health, and I cannot recommend it enough.

    I’d been experiencing muscle cramps, so I decided to use this test. It was easy to use and I got my results promptly. Now I know what I need to focus on in my diet to try and alleviate the cramps.

  9. Eleanor

    My journey with the Mineral Deficiency Test began out of sheer curiosity. While I didn’t exhibit overt symptoms, I wanted a holistic view of my health. The entire testing process was streamlined, and the clarity of instructions stood out. 🙂 However, the comprehensive analysis was the true game-changer. Beyond showcasing mineral levels, it detailed potential implications of imbalances and provided guidance on rectifying deficiencies. The newfound knowledge allowed me to tweak my diet, introducing foods rich in minerals I lacked. The uplift in my energy and mood has been a testament to the test’s precision and the power of balanced nutrition.
