Magnesium (Mg): What Affects The Test
Content provided by Healthwise
What Affects the Test
Reasons you may not be able to have the test or why the results may not be helpful include:
- Using medicines that contain magnesium. This includes many antacids, laxatives (such as milk of magnesia or Epsom salts), and magnesium supplements.
- Medicine. Some antibiotics, insulin, and long-term use of diuretics can lower magnesium levels.
- Recent intravenous (IV) fluids, such as fluids given during surgery.
- Pregnancy. Magnesium blood levels may normally be low in the second and third trimesters of pregnancy.
