This blood test seeks the Magnesium level, a low level of which can cause fatigue, muscle weakness, cramps, muscle spasms or even convulsions.

Magnesium is the second most common mineral found inside cells, second only to potassium. It is key to more than 300 reactions in our bodies. A serum magnesium test should be considered when a patient is suspected of having a lack - particularly seen in malnutrition, alcoholism, and diarrhoea amongst others. Dietary deficiency is surprisingly common though even in the western world - so if reduced intake is suspected this is a test worth considering.

Great service and product. The turn around is brilliant (mostly - there was a glitch during the early part of the Covid pandemic, but that seems to be resolved now). Tests are recognised by the medical profession so I am able to use the results to get the treatment I need without further tests.

I had various questions which they answered via email/webchat and the timing of getting a kit, sending it back and getting the results was good.
