Minerals and Their Essential Functions for Health

Minerals are crucial for maintaining optimal health. They serve a variety of functions, including acting as building materials for strong bones and muscles. Minerals also play key roles in various metabolic pathways, ensuring the normal functioning of cells.

Some minerals, like Magnesium, Zinc, and Selenium, which are tested in GetTested’s blood test, are especially important as immune system boosters.


Magnesium supports healthy muscles, strong teeth, and bones. Our bodies cannot produce it, so we need to consume magnesium-rich foods. Magnesium not only boosts your energy but also improves your mood. Taking it before bedtime can aid relaxation and promote good sleep. Its deficiency can lead to physical and mental weakness, and hyporeflexia (reduced or absent reflexes). You can find magnesium in many foods and supplements.


Zinc, an antioxidant, is vital for producing B- and T-cells in the immune system. It also aids in wound healing, treats diarrhea, and is necessary for DNA and protein synthesis. Zinc is present in many foods and is crucial for male sexual health and bone health, potentially helping prevent osteoporosis. Extensive research confirms Zinc’s importance for overall health and its multitude of benefits.


Selenium, an essential mineral not produced by the body, is found in various foods. It aids in DNA synthesis, protects red blood cells against infections, and boosts white blood cell function. It also supports thyroid function and reproductive health. Studies have shown that low selenium levels may increase the risk of developing cancer.

Mineral Deficiency Symptoms

Many people experience vague symptoms for years without a mineral deficiency diagnosis. GetTested’s quick checkup can provide a full report on your mineral status and practical diet optimization tips. Common symptoms for each tested mineral include:

  • Magnesium Deficiency: Sleep disorders, fatigue, irritation, eyelid twitching, muscle cramps/tremors, hypertension.
  • Zinc Deficiency: Weakened immune system, impaired wound healing, reduced sense of smell and taste, poor hair, skin, nails, infertility/impotence/low testosterone, impaired vision or night vision.
  • Selenium Deficiency: Muscle weakness, muscle pain, growing pains, restless legs, skin problems, fatigue.

How the Mineral Deficiency Test Works

The Mineral Deficiency Test measures mineral levels in plasma (blood). You can easily take the test at home by pricking your finger and sending the sample to our lab. You will receive your results digitally as soon as our lab completes the analysis. The test kit, containing everything needed for the test, will be sent directly to your home.


How is the Mineral deficiency test carried out?

Our Mineral deficiency test is a home test kit. After ordering, we will send you a kit with everything you need to collect a small blood sample. Then, simply return your sample to us in the pre-paid envelope.

Who should get a Mineral deficiency test?

Individuals experiencing symptoms of fatigue, weakened immunity, or hormonal imbalances may benefit from testing their magnesium, zinc, and selenium levels. These tests can also be valuable for athletes, those with dietary restrictions, and individuals with chronic health conditions.

What happens if I fail to take the sample?

If you read the instructions carefully before you take the test and it should go well. Should something go wrong, you are welcome to contact us and we will help you.

How quickly will I receive my results?

Once we receive your sample, average response time is 10-15 business days to receive results.

When should I take the test?

It is recommended to take the test on an empty stomach in the morning.
