Overview of Magnesium
What is Magnesium?
Preparation for Magnesium
- Do not eat or drink anything other than water for 8-12 hours before the test.
Why Get Tested for Magnesium?
The Magnesium Test is performed:
· As a part of regular health checkups to measure magnesium levels in the blood
· Upon the appearance of symptoms indicating magnesium deficiency like muscular weakness, muscle twitch or cramps, irregular heartbeats or cardiac arrhythmia, seizures, etc.
· To monitor treatment efficacy of magnesium supplements at regular intervals
· As a part of checkups for evaluating kidney diseases, malnutrition, diarrhea, and alcoholism
Understand more about Magnesium
Magnesium is a mineral micronutrient which plays essential roles in body processes including enzyme functions, energy production by metabolism, contraction of muscles, and nerve functioning. It also helps in the metabolism of calcium and hence helps in the maintenance of healthy bones. Magnesium is supplied to the body from dietary sources and is absorbed in the small intestines and colon. It is subsequently absorbed into the bones and tissues. Only about 1% of the total amount of magnesium absorbed remains in the blood within a narrow normal range. The normal range of magnesium concentration is maintained mainly by regulation of the amount absorbed from food and excreted in urine.
Deviation from the normal range of magnesium concentration causes Hypomagnesia (shortage of magnesium), or Hypermagnesia (excess of magnesium). Both these conditions impact normal body processes in the short term and may give rise to other conditions in the long term.
What Results of Magnesium mean?
Normal range: 0.85 to 1.10 mmol/L (1.7 to 2.2 mg/dL approx.)
Hypomagnesia: Below 0.85 mmol/L (Less than 1.7 mg/dL approx.)
Hypermagnesia: Above 1.10 mmol/L (Above 2.2 mg/dL approx.)
Magnesium concentration in the body is maintained within a narrow normal range between 0.85 mmol/L and 1.10 mmol/L.
Hypomagnesia or low blood magnesium is indicated if magnesium concentration lies below the normal range.
Hypermagnesia or high blood magnesium is indicated if magnesium concentration lies above the normal range.
