Why Get Tested?
Reasons for ordering the prealbumin test are undergoing reassessment as understanding of prealbumin is evolving. Historically, prealbumin has been ordered to help detect protein-calorie malnutrition and to monitor the effectiveness of parenteral (for example, intravenous) nutrition. Newer evidence suggests that the reasons for changes in prealbumin levels may be more complex and the test should not be interpreted as a simple indicator of nutritional status.
When to Get Tested?
No current consensus exists on when to get tested, although prealbumin may be ordered, along with assessments of nutritional intake, when a health practitioner suspects that someone is malnourished or is at risk of malnutrition.
