About this test

Magnesium Blood Test in Slough
Magnesium is the fourth most abundant positively charged ion (cation) in the human body, with approximately 50% stored in the bones alongside calcium and phosphate. It plays a vital role in numerous physiological processes and is essential for maintaining overall health.

Functions of Magnesium in the Body
Magnesium is involved in various critical biochemical and cellular functions, including:

Activation of enzymatic processes such as phosphorylation

Protein synthesis and DNA metabolism

Regulation of neuromuscular conduction

Supporting the excitability of skeletal and cardiac muscles

High Magnesium Levels (Hypermagnesemia)
Elevated serum magnesium concentrations may occur in conditions such as:

Renal failure

Acute diabetic acidosis

Dehydration

Addison’s disease

Severe hypermagnesemia can depress the central nervous system, leading to general anaesthesia, respiratory failure, and cardiac arrest due to disrupted heart conduction.

Low Magnesium Levels (Hypomagnesemia)
Reduced magnesium levels may result from:

Chronic alcoholism

Malabsorption syndromes

Severe diarrhoea or acute pancreatitis

Diuretic therapy

Prolonged IV fluid therapy without magnesium

Kidney disorders such as glomerulonephritis and tubular reabsorption defects

Symptoms of hypomagnesemia include muscle cramps, tetany, convulsions, and irregular heart rhythms (arrhythmias).

When is Magnesium Testing Recommended?
A magnesium test is often ordered to investigate unexplained muscle weakness, abnormal heart rhythms, or electrolyte imbalances. It also supports the diagnosis of chronic kidney disease, gastrointestinal disorders, and endocrine conditions.
