What is the target lab value for Magnesium?

1. 1.0-1.5 mg/dL

2. 1.7-2.5 mg/dL

3. 2.0-3.0 mg/dL

4. 3.0-4.0 mg/dL

The correct answer is: 1.7-2.5 mg/dL

The target lab value for magnesium is typically in the range of 1.7 to 2.5 mg/dL. This range is considered normal and necessary for various biochemical processes in the body, including nerve function, muscle contraction, and the regulation of blood pressure. Maintaining magnesium levels within this target range is crucial, as both low and high magnesium levels can lead to significant health issues. A level below 1.7 mg/dL can indicate hypomagnesemia, which can cause symptoms like muscle cramps, weakness, and cardiac problems. Conversely, elevated magnesium levels (hypermagnesemia) can occur due to various medical conditions or excessive supplementation and may lead to complications such as respiratory distress or cardiac arrest. Thus, targeting a lab value for magnesium within the 1.7 to 2.5 mg/dL range is essential for ensuring adequate magnesium levels for optimal health and physiological functioning.
