Web2 mrt. 2024 · Unionized ammonia is very toxic to aquatic animals, particularly fish, because it can readily diffuse across gill membranes (Sampaio et al. 2002). Ionized ammonia does not pass as easily through gill membranes, so it is appreciably less toxic than the unionized form (Camargo and Alonso 2006). WebPurpose: Ionized fraction (iMg) is the physiologically active form of magnesium (Mg); total Mg may not accurately reflect iMg status. Erroneously "low" Mg levels may result in unnecessary repetitive testing. Materials and methods: From 11/2015 to 01/2016, patients ordered for Mg from a pilot ICU also had iMg tested.
