What prealbumin level indicates malnutrition?
Serum prealbumin concentrations less than 10 mg/dL are associated with malnutrition [31]. The use of prealbumin has been advocated as a nutritional marker, particularly during refeeding and in the elderly [32].
What labs indicate malnutrition?
IV. Lab Indicators of Malnutrition in Adults
- Serum Prealbumin <15 mg/dl. Best marker for Malnutrition. See Prealbumin for interpretation and monitoring.
- Serum Albumin <3.4 mg/dl.
- Serum Transferrin <200 mg/dl.
- Total Lymphocyte Count <1500/mm3.
- Total Cholesterol <160 mg/dl.
Why is albumin low in malnutrition?
Deficient protein intake results in the rapid loss of cellular ribonucleic acid and disaggregation of the endoplasmic reticulum–bound polysomes and, therefore, decreased albumin synthesis. Albumin synthesis can decrease by more than one third during a 24-hour fast.
How does albumin indicate malnutrition?
One study found that using serum albumin levels < 3.5 g/dL as the sole parameter for malnutrition would have low specificity for identifying nutritional status in the functionally impaired elderly [21]. It would result in up to 80% of the individuals being wrongfully diagnosed as malnourished.
What do prealbumin levels indicate?
Prealbumin is a protein made in your liver. 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.

What is prealbumin vs albumin?
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. Measuring prealbumin can help clinicians detect short-term impairment of energy intake and the effectiveness of nutritional support efforts.
Is prealbumin a good indicator of nutritional status?
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 causes a low prealbumin level?
If your prealbumin levels are lower than normal, it may mean you are not getting enough nutrition in your diet. Low prealbumin levels may also be a sign of: Trauma, such as a burn injury. Chronic illness.
