What is the expected reference range for pre-albumin levels?

Pre-albumin, also known as thyroxine-binding prealbumin, is a protein that serves as a marker for nutritional status, particularly in assessing protein synthesis and liver function. The expected reference range for pre-albumin levels in adults is typically between 15 to 36 mg/dL.

This range is important as it helps healthcare professionals evaluate a patient's nutritional state, especially in the context of acute or chronic illnesses where protein malnutrition may be a concern. Low levels of pre-albumin can indicate malnutrition, inflammation, liver disease, or other health issues, while levels within the reference range suggest adequate protein status and liver function.

Understanding pre-albumin levels is crucial for dietary planning and intervention in clinical settings, making it an essential component of patient assessments focused on nutrition.
