According to the Academy’s Evidence Analysis Library, serum proteins such as albumin and prealbumin are not included as defining characteristics of malnutrition because evidence analysis shows that serum levels of these proteins do not change in response to changes in nutrient intake.
Why should you not use albumin as an indicator of malnutrition?
Serum albumin and prealbumin do not serve as valid proxy measures of total body protein or total muscle mass and should not be used as nutrition markers. The serum concentrations of albumin and prealbumin decline in the presence of inflammation, regardless of underlying nutrition status.
What is the best indicator of malnutrition?
The indicators stunting, wasting, overweight and underweight are used to measure nutritional imbalance; such imbalance results in either undernutrition (assessed from stunting, wasting and underweight) or overweight.
What does albumin and prealbumin measure?
Prealbumin, also called transthyretin, is the precursor to albumin. Its half-life is 2 to 4 days, whereas the half-life of albumin is 20 to 22 days. 4. Measuring prealbumin can help clinicians detect short-term impairment of energy intake and the effectiveness of nutritional support efforts.
Does prealbumin indicate nutrition?
Prealbumin helps carry thyroid hormones and vitamin A through your bloodstream. It also helps regulate how your body uses energy. If your prealbumin levels are lower than normal, it may be a sign of malnutrition.
Is albumin a good indicator of malnutrition?
Serum Albumin. Albumin is the most abundant protein in human serum. It has been used for decades as an indicator of malnutrition in patients in clinically stable conditions (review and meta-analysis [24]).
Why is albumin not a good indicator of protein status?
Serum albumin increases as inflammation subsides, regardless of how much protein is consumed. Because of its relationship to inflammation, serum albumin is no longer considered a good indicator of malnutrition or protein repletion.
How does albumin affect nutritional status?
Albumin is the most abundant plasma protein. Its essential role is to regulate passage of water and solutes through the capillaries by maintaining colloidal oncotic pressure within the vasculature. Plasma proteins have long been considered integral to assessment of nutritional status.
Is albumin slow to reflect changes in nutrition status?
Serum albumin level has been used as an indication of chronic nutritional status. However, albumin turnover is slow (t½ of 20 days). Therefore other plasma proteins, such as prealbumin binding protein (t½ of 2 days) and retinol-binding protein (t½ of 12 hours) are indications of a more current nutritional status.
What is the best way to determine malnutrition?
One way to measure malnutrition is to study nutrition-related outcomes, such as growth restriction, weight loss, and the occurrence of deficiency-related disorders. Common indicators recommended by the WHO include anthropometric measurements, biochemical indicators, and clinical signs of malnutrition.
What is the best indicator of nutritional status?
Anthropometric measurements to assess growth and development, particularly in young children, are the most widely used indicators of nutritional status in a community. The percentage of low height-for-age reflects the cumulative effects of under-nutrition and infections since birth, and even before birth.
What is the severe indicator of malnutrition?
In addition to the presence of nutritional edema, two indicators are recommended by the World Health Organization for the diagnosis of acute malnutrition: weight-for-height Z-scores (WHZ; with acute malnutrition defined as WHZ Is BMI a good indicator of malnutrition?
Identifying Malnutrition – Body Mass Index(BMI) It is simple to use, tends to be widely used and provides some indication as to an individual’s likely nutritional status, as a low BMI is argued to indicate a greater likelihood of inadequate nutritional intake.
What does low albumin and prealbumin indicate?
Low prealbumin scores mean that you are likely to need a nutritional assessment. Low prealbumin scores may also be a sign of liver disease, inflammation, or tissue death (tissue necrosis). High prealbumin scores may be a sign of long-term (chronic) kidney disease, steroid use, or alcoholism.
What does albumin measure?
Albumin is a protein made by the liver. A serum albumin test measures the amount of this protein in the clear liquid portion of the blood. Albumin can also be measured in the urine.
What does prealbumin level tell you?
The prealbumin blood test helps your doctor determine if you’re getting enough nutrients — namely, protein — in your diet. It is done in your doctor’s office with the simple taking of a sample of your blood.
What albumin level indicates malnutrition?
Serum albumin level is an indicator of visceral protein reserves and nutritional status. Protein malnutrition is associated with a serum albumin level of less than 3.5 g/dL if liver function is normal.

Difference Between Albumin and Prealbumin
Albumin vs Prealbumin. Prealbumin and albumin are two indicators used to assess protein status at the visceral level. If someone is having some wounds, he will need ample protein so that wound healing can take place. Thus, if there is malnutrition as stipulated by the prealbumin and albumin measurements then this must be corrected first above all else.
