It measures the concentration of magnesium in the water portion of your blood. However, since only 1% of your body\u2019s magnesium lies in the blood, and 0.3% in the serum, the serum test doesn\u2019t reflect whole-body magnesium.&nbsp;<\/p>\n\n\n\n<p>You can have normal or even high serum magnesium, even while your whole body is low in or losing magnesium. For example, stress can raise serum magnesium, but it causes your entire body to lose magnesium.<span class=\"custom-citation\" data-id=\"ref-5\"><\/span> In fact, among ICU patients, high-normal serum magnesium predicts deaths in the hospital.<span class=\"custom-citation\" data-id=\"ref-6\"><\/span>&nbsp;<\/p>\n\n\n\n<p>Serum levels can also be affected by many things, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Time of the day that you draw the blood<\/strong><\/li>\n\n\n\n<li>The amount of albumin in the blood<\/li>\n\n\n\n<li><strong>Kidney filtration<\/strong><\/li>\n\n\n\n<li>And more<\/li>\n<\/ul>\n\n\n\n<p>If you\u2019ve just taken a <a href=\"https:\/\/bioptimizers.com\/shop\/products\/magnesium-breakthrough\" target=\"_blank\" rel=\"noreferrer noopener\">magnesium supplement<\/a>, your serum magnesium levels will increase.

The values then can be compared to reference ranges or previous measurements to assess magnesium balance.<\/p>\n\n\n\n<p>Lower levels of urinary magnesium excretion may suggest magnesium deficiency, while higher levels may indicate excess magnesium or impaired kidney function. However, urine magnesium levels may not acutely reflect magnesium levels in the body, as results are dependent on how much the kidneys are filtering or absorbing. There is also a poor correlation between serum magnesium levels and urinary magnesium levels.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"452\" src=\"https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/08\/image-3-1024x452.png\" alt=\"\" class=\"wp-image-150302315470\" srcset=\"https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/08\/image-3-1024x452.png 1024w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/08\/image-3-768x339.png 768w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/08\/image-3-1536x677.png 1536w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/08\/image-3.png 1882w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4.

The loading challenge can also be used to monitor your response to magnesium supplements, or to assess how well supplementation works for certain conditions when deficiency is common or suspected.<\/p>\n\n\n\n<p>This test involves administering a controlled dose of magnesium, typically intravenously (through an IV). By administering magnesium this way, it bypasses the normal digestive processes and allows it to be directly delivered to the bloodstream.<\/p>\n\n\n\n<p>Once the magnesium solution is administered, the health provider administering the test will monitor how much magnesium is excreted in your urine over a specific period. This period is usually over 24 hours. One specific test, called <strong>Thoren\u2019s intravenous magnesium load<\/strong>, is conducted over 16 hours.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/06\/3-4-1024x683.png\" alt=\"\" class=\"wp-image-150302315098\" srcset=\"https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/06\/3-4-1024x683.png 1024w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/06\/3-4-768x512.png 768w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/06\/3-4-1536x1024.png 1536w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/06\/3-4.png 1608w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Results are interpreted by comparing the amount of magnesium administered to the amount excreted in the urine. If the excretion of magnesium is much higher than expected, it suggests the body has difficulty retaining or using magnesium effectively and indicates a deficiency.<\/p>\n\n\n\n<p>Thoren\u2019s magnesium load test is interpreted slightly differently. His work suggests that if less than 70% of IV magnesium is given over 16 hours, magnesium deficiency is likely. This is because the body is trying to take up as much magnesium as possible, so less is excreted in the urine. This method should be used in combination with other magnesium markers but indicates that high magnesium uptake means deficiency is likely even when blood levels are normal.<\/p>\n\n\n\n<p>Both tests are particularly helpful when there is a suspected deficiency, but other laboratory results are unclear. However, both tests require supervision under a healthcare provider and urinary measurements to be accurate, which can pose challenges when trying to interpret results. It also tends to be expensive.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"448\" src=\"https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/08\/image-4-1024x448.png\" alt=\"\" class=\"wp-image-150302315471\" srcset=\"https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/08\/image-4-1024x448.png 1024w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/08\/image-4-768x336.png 768w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/08\/image-4-1536x673.png 1536w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/08\/image-4.png 1836w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>5.
