What is the standard range for albumin levels in serum?

2.5-4.0 g/dL
3.0-4.5 g/dL
3.5-5 g/dL
4.5-6.0 g/dL

The correct answer is: 3.5-5 g/dL

The standard range for albumin levels in serum is 3.5-5 g/dL. This range is significant because albumin is a crucial protein synthesized in the liver, playing a vital role in maintaining oncotic pressure within the blood vessels, transporting various substances, and reflecting the nutritional status of the patient. When examining serum albumin levels, it's essential for healthcare providers to understand that lower levels can indicate potential health issues, such as liver disease, kidney disease, or malnutrition, while higher levels may suggest dehydration or other conditions. Keeping in mind this normal range helps healthcare professionals interpret diagnostic tests accurately and assess a patient's overall health or response to treatment effectively.
