What is the normal range for albumin levels in the blood?

  1. 3.0-4.0 g/dL

  2. 4.0-5.0 g/dL

  3. 4.0-6.0 g/dL

  4. 3.5-5.5 g/dL

The correct answer is: 4.0-5.0 g/dL

The normal range for albumin levels in the blood is typically around 3.5 to 5.0 grams per deciliter (g/dL). Albumin is a crucial protein made by the liver and plays a vital role in maintaining oncotic pressure and transporting various substances throughout the body. While the selected range of 4.0-5.0 g/dL is slightly narrower than the broader context of normal values, it does reflect a common reference point used in many clinical settings. In clinical practice, a level below this range may indicate liver disease, kidney disease, or malnutrition, while elevated levels can suggest dehydration or other health issues. Understanding this range is important for dialysis technicians as they frequently monitor patients' lab values to assess their health status and treatment efficacy.
