Zinc Sulfate Turbidity Test

The zinc sulphate turbidity test is one of the important tests for determining the level of plasma protein and analyzing its components as liver diseases. Principle The y globulin in serum is precipitated and precipitated in a low concentration of zinc sulphate solution, and the degree of turbidity is proportional to the content of gamma globulin. Turbidity is expressed in units compared to standard tubes. Basic Information Specialist classification: Digestive examination classification: liver function test Applicable gender: whether men and women apply fasting: fasting Tips: Do not eat too greasy, high-protein foods, avoid heavy drinking. Normal value The normal value is 2 to 12 units. Clinical significance Abnormal result (1) significantly increased 1 Liver cirrhosis of liver disease, active period of chronic hepatitis, hepatocellular carcinoma, acute hepatitis, autoimmune hepatitis, etc. 2 non-hepatic chronic inflammation, collagen disease, tuberculosis, sarcoma-like disease, multiple myeloma, malignant tumors, etc. (2) Significantly reduce intrahepatic bile stasis, extrahepatic bile stasis, multiple myeloma, disease with high proteinuria, long-term use of adrenocortical hormone, long-term use of immunosuppressants, anti-tumor drugs. Need to check the population of chronic inflammation, high proteinuria and other symptoms. High results may be diseases: liver cirrhosis, hepatitis precautions Not suitable for the crowd: no. Contraindications before inspection: Configure the required solution and the standard test tube solution to be controlled. Pay attention to the pH and concentration of the solution. Taboo when checking: 1. Use the same standard turbidity tube. 2. Serum should be fresh. Inspection process 1. Take the patient's blood and separate the quantitative serum. 2. Take one tube of the same diameter as the standard tube, add 0.1ml of fresh serum, add 6ml of zinc sulphate barbital buffer, mix well, and let it stand at room temperature for 30mln, then turbid with the standard tube, it will be turbid The number of degrees. Not suitable for the crowd There is usually no special population. Adverse reactions and risks No special complications.
