Serum albumin (ALB, A)
Serum albumin is the major protein component of serum total protein and is synthesized by the liver. It plays an important role in maintaining blood colloid osmotic pressure, metabolism of metabolites in the body, and nutrition. In the case of liver disease, serum albumin levels are often detected to aid diagnosis and prognosis. Since the half-life of albumin is about 19 days, when liver lesions occur, it is often necessary to change the albumin to a certain extent and to a certain extent.Basic Information
Specialist classification: Digestive examination classification: biochemical examination
Applicable gender: whether men and women apply fasting: fastingAnalysis results:
Found in cirrhosis with taxation and other serious liver damage (such as acute liver necrosis, toxic hepatitis, etc.), malnutrition, chronic wasting disease, diabetes, severe bleeding, nephrotic syndrome, congenital albumin deficiency.
Serum albumin: 35-55g/L
Increased albumin concentration: (1) common in severe water loss, caused by plasma concentration. Such as severe dehydration, shock, severe burns, acute bleeding, chronic adrenal insufficiency. (2) Excessive albumin infusion. (3) Diseases with elevated albumin concentrations have not been found.
35 ~ 55g / L.Clinical significance
Increased albumin concentration:
1, common in severe water loss, caused by plasma concentration. Such as severe dehydration, shock, severe burns, acute bleeding, chronic adrenal insufficiency.
2. Intravenous infusion of too much albumin.
3. Diseases with elevated albumin concentrations have not been found.
Decrease in albumin concentration:
Found in cirrhosis with ascites and other serious liver damage (such as acute liver necrosis, toxic hepatitis, etc.), malnutrition, chronic wasting disease, diabetes, severe bleeding, nephrotic syndrome, congenital albumin deficiency.Low results may be diseases: malnutrition, burns, burn shock, cirrhosis, ascites results may be high disease: children with primary nephrotic syndrome, cirrhosis, diabetes considerations
1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results.
2. Fasting for 12 hours before taking blood, taking fresh blood for inspection.
When you draw blood, you should relax your mind, avoid the contraction of blood vessels caused by fear, and increase the difficulty of blood collection.
1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma.
2, the pressing time should be sufficient. There is a difference in clotting time for each person, and some people need a little longer to clotting. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended.
3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved.
4. If there is localized congestion, use a warm towel after 24 hours to promote absorption.Inspection process
Immediately after the blood of the subject is withdrawn, it is sent for examination by chemical or immunoturbidimetry or dry chemistry.Not suitable for the crowd
No taboos.Adverse reactions and risks
This check will not cause harm to the human body.
