Vitamin A binding protein (RBP)

Vitamin A binding protein is a vitamin transport protein in the blood, which is synthesized by the liver and widely distributed in blood, urine, cerebrospinal fluid and other body fluids. Determination of vitamin A binding protein can detect tubular damage in the early stage, and can sensitively reflect the degree of damage of renal proximal convoluted tubules, and can also be used as an indicator of early damage and monitoring of liver function. Basic Information Specialist classification: inspection classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Found in vitamin A deficiency, liver disease (such as the exclusion of excess nutrient liver) such as acute and chronic hepatitis, cirrhosis, hypoproteinemia, malabsorption syndrome, obstructive jaundice, hyperthyroidism, infection, trauma and so on. Normal value: RBP (male): 36-56mg/L RBP (female): 26.7-57.9mg/L Above normal: Found in chronic glomerulonephritis, renal cirrhosis, diabetic kidney damage, systemic lupus erythematosus and other renal insufficiency, over-nutrition fatty liver, hypothyroidism and so on. negative: Positive: Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. Normal value ELISA method, RIA method Male: 36 ~ 56mg / L (36.0 ~ 56.0μg / ml); Female: 26.7 to 57.9 mg/L (26.7 to 57.9 μg/ml). (Note the specific reference value depends on each laboratory.) Clinical significance Abnormal result 1, reduction: seen in vitamin A deficiency, liver disease (such as excluding nutrient excess fatty liver) such as acute and chronic hepatitis, cirrhosis, etc., hypoproteinemia, malabsorption syndrome, obstructive jaundice, hyperthyroidism, infection , trauma and so on. 2, elevated: seen in chronic glomerulonephritis, renal cirrhosis, diabetic kidney damage, systemic lupus erythematosus caused by renal insufficiency, over-nutrition fatty liver, hypothyroidism and so on. Low results may be diseases: precautions for vitamin A deficiency in children Inappropriate crowd: There is usually no special population. Please inform the doctor about the recent medication and special physiological changes before the test. Taboo before inspection: 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. After 8 pm on the day before the medical examination, you should start fasting for 12 hours to avoid affecting the test results. Requirements 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. Inspection process Immediately after the blood sample is collected, the test method is as follows: the anti-human μ chain plate is used to capture the IgM in the serum to be tested, and then the EHF virus antigen is added, and finally the anti-EHF virus monoclonal antibody conjugate is labeled with the enzyme to recognize and make the bottom. The color of the object. Not suitable for the crowd No malnutrition, vitamin deficiency. Adverse reactions and risks no.
