In the context of the bone-vascular axis, magnesium may also be involved in the risk of fracture. In the International System of Units (SI), magnesium in the blood is measured in mmol/L. Serum magnesium is a very inaccurate measurement of magnesium in the body. Serum magnesium constitutes only a small fraction of total body stores and may not predict magnesium status correctly. Blood monitoring should be performed to patients who are receiving magnesium sulfate to ensure that their serum magnesium level is within the normal range. Abnormalities in magnesium homoeostasis may co-exist with other electrolyte abnormalities. Most laboratories measure total magnesium; measurement of ionised magnesium is not standard practice. It should be noted that, although total serum magnesium levels of hemodialysis patients are often above the reference range, the concentration of ionized magnesium, a biologically active form of magnesium, is largely normal or even low. My GP told me that the low magnesium is probably just the aftermath of a low thyroid and that it will correct on its own, but if I wanted he suggested I take some supplements. Serum magnesium lower than 1.8 mg/dL is considered low. Instructions.
