Prealbumin Test Overview:

The prealbumin test measures the level of prealbumin, a protein produced by the liver that plays a role in transporting thyroid hormones and retinol (vitamin A). Prealbumin levels are often used to assess nutritional status and the liver's ability to produce proteins.

Risk Assessment:

Prealbumin levels can be influenced by a variety of factors, including:

• Nutritional status: Low levels are often seen in malnutrition or protein deficiency.
• Liver disease: Since prealbumin is produced by the liver, liver dysfunction can lower levels.
• Acute or chronic inflammation: Inflammatory conditions can reduce prealbumin levels.
• Kidney disease: Kidney dysfunction can lead to protein loss in the urine, which can lower prealbumin levels.

Normal Range:

19-38 mg/dL (milligrams per deciliter).

However, ranges can vary, so it's important to consult the specific lab's reference range.

Interpretation:

• Low prealbumin levels: Typically suggest poor nutritional status, malabsorption, liver disease, inflammation, or protein loss.
• Normal or high prealbumin levels: Can suggest a well-nourished state, but higher levels can also be seen in certain conditions like acute kidney disease or recovery from a previous illness.

Sample Type:

The sample for a prealbumin test is usually blood serum or plasma. The blood sample is typically drawn from a vein in your arm.
