Magnesium Deficiency (Hypomagnesemia): Test and Diagnosis

Laboratory parameters of the 1st order – obligatory laboratory tests.

• Electrolytes – calcium, chloride, potassium, magnesium, sodium, phosphate.

Laboratory parameters 2nd order – depending on the results of the medical history, physical examination, etc. – for differential diagnostic clarification.

• Urine status (rapid test for: pH, leukocytes, nitrite, protein, glucose, ketone, urobilinogen, bilirubin, blood).
• Glucose (fasting glucose, fasting blood glucose).
• Determination of magnesium concentration in 24h collection urine – to differentiate between intestinal and renal magnesium loss [> 1mmol/l indicates renal magnesium loss].
