Serum Prealbumin (PA)

Serum prealbumin is a glycoprotein synthesized by the liver and consists of four identical subunits with a half-life of 0.5 days, which is involved in the synthesis of T3, T4, vitamins and retinol proteins. Serum prealbumin assay can reflect the function of liver synthesis and secretion of proteins, can be used as an early indicator of liver damage and suggest changes and prognosis of some diseases. Basic Information Specialist classification: Digestive examination classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Tips: fasting blood test. Before the examination, the doctor should be told in detail about the recent medications and physiological changes such as pregnancy. Since the half-life of serum prealbumin is only 0.5 days, the decline occurs earlier in liver disease. Normal value 1. Acetate fiber membrane electrophoresis method is 0.28~0.35g/L. 2. Immunodiffusion method Male 233.5 ~ 372.7mg / L. Female 217.75 ~ 337.65mg / L. Children 160.7 ~ 327.9mg / L. 3. The scattering nephelometry method is 213.0 to 441.9 mg/L. Clinical significance 1. Elevation is seen in the recovery period of acute hepatitis, alcohol withdrawal, Hodgkin's disease, nephrotic syndrome (overeating protein diet). 2, reduced in severe hepatitis, acute hepatitis, chronic active hepatitis, non-compensatory cirrhosis, liver cancer, obstructive jaundice, ulcerative colitis, hyperthyroidism, malnutrition. Low results may be diseases: high results in children with liver failure may be diseases: Hodgkin's disease, nephrotic syndrome precautions 1. Fasting blood test. Before the examination, the doctor should be told in detail about the recent medications and physiological changes such as pregnancy. 2. Since the half-life of serum prealbumin is only 0.5 days, the decline occurs earlier in liver disease. 3. In case of malnutrition, this test can be used as a monitoring indicator for diagnosis and treatment. 4. If the prealbumin continues to remain low or further decreased, it indicates a poor prognosis. Inspection process Take an appropriate amount of blood and immediately send it for inspection. Not suitable for the crowd Inappropriate people: Generally there are no people who are not suitable. Adverse reactions and risks Elevation or decrease indicates an abnormality in liver and kidney function.
