What is the target lab value for Phosphorous?

2.5-4.5 mg/dL
3.0-4.0 mg/dL
3.5-5.5 mg/dL
4.5-6.0 mg/dL

The correct answer is: 3.5-5.5 mg/dL

The target lab value for phosphorus in the context of a dialysis patient is generally considered to be between 2.5 and 4.5 mg/dL. Maintaining phosphorus levels within this range is crucial for patients with kidney dysfunction, as the kidneys are responsible for regulating phosphorus balance in the body. Elevated phosphorus levels can lead to complications such as cardiovascular disease and bone disorders, particularly in patients receiving dialysis. The rationale for the target range specifically focuses on ensuring that phosphorus levels do not exceed the upper limit, which can create a variety of health issues, including deposits in tissues and potential calcification of blood vessels. Therefore, keeping the phosphorus levels within the recommended range is essential for the overall health and well-being of patients undergoing dialysis treatment.
