What is a Magnesium blood test?

Magnesium Test Kit at home, Test UK, and Blood test are the most used search terms for ordering an online test kit for home delivery.

Thus, it is an essential mineral for the proper functioning of the human body. A small proportion of the body (0.05% of the total body weight) is essential from a structural and functional point of view.

Why get a Magnesium blood test?

You may need a magnesium blood test if you experience low or high levels of symptoms.

  • Weakness.
  • Irregular heartbeat.
  • Convulsions (in severe cases).
  • Muscle deterioration.
  • Fatigue.
  • Vomiting and nausea.

Instructions for use

Also, please take your sample in the morning. Take it at least one hour before any medication.

When collecting your sample, try the following tips:

  • Drink plenty of water. Being well-hydrated will make it easier to collect your sample.
  • Take a shower before you take your test, or run your hands under warm water for a few minutes, as heat improves blood flow.
  • Do light exercise (move around, walk, etc.) to get the blood flowing.
  • Ensure your arm is below your heart level – let gravity do some of the work.
  • Nails that are too long can make it difficult to collect a sample.
  • Do not shake the sample vigorously but invert the tube gently 10 times. (gently swirl the tube after each drop of blood).
  • Do not squeeze (milk) the finger.
  • Re-warm your hands during collection where needed.

Please take your Magnesium test UK sample from Monday to Thursday to avoid delivery delays at the lab. 

Furthermore, Medicines Online Scientists are trained to follow Laboratory procedures set by instrument providers from global sources. And then, subject to training and certification, each scientist processes your samples the same day and issues your results.
