Anti-pylori IgG antibody

Helicobacter pylori infection is an important cause of chronic gastritis. Helicobacter pylori-associated chronic gastritis can cause local and systemic immune responses to Helicobacter pylori, and H. pylori antibodies are produced by humoral immunity after H. pylori infection. This reaction constitutes the specific identification of HP antibodies in serum. Foundation and attempt to diagnose and evaluate efficacy by serological methods. There are many commercial ELISA kits for detecting the status of HP antibodies, which use different antigens, although the literature related to kit manufacturing often reports high sensitivity and specificity; independent studies have shown that certain The sensitivity and specificity of a particular kit are quite different in different studies, so any laboratory that wants to use serology to diagnose HP infection should ensure that the kits used are highly sensitive and specific. And has been properly verified in the population tested. Basic Information Specialist classification: Digestive examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: abnormal. Tips: Do not eat too greasy, high-protein foods the day before the blood draw, avoid heavy drinking. Normal value negative. Clinical significance Abnormal results Serum HP antibody is one of the basic methods for diagnosing Helicobacter pylori infection. It is a non-invasive test, which is convenient and rapid, but it does not reflect the real-time infection status of Helicobacter pylori. After Helicobacter pylori eradication, serum antibody needs to be reduced to 6 months. . Suitable for epidemiological investigations, for the initial screening test for clinical treatment. Its sensitivity is 88% to 90%, and its specificity is 86% to 90%. Need to check patients with chronic gastritis, Helicobacter pylori infection patients. Positive results may be diseases: chronic gastritis precautions Abnormal people: generally no special population. Taboo before the test: Do not eat too greasy, high-protein food the day before the blood draw, avoid heavy drinking. The alcohol content in the blood directly affects the test results. After 8 pm on the previous day, you should start fasting for 12 hours to avoid affecting the test results. Requirements for examination: When taking blood, you should relax your mind, avoid the contraction of blood vessels caused by fear, and increase the difficulty of blood collection. Inspection process Serum HP antibody is one of the basic methods for diagnosing Helicobacter pylori infection. It is a non-invasive test, which is convenient and rapid, but it does not reflect the real-time infection status of Helicobacter pylori. After Helicobacter pylori eradication, serum antibody needs to be reduced to disappear within 6 months. Suitable for epidemiological investigations, for the initial screening test for clinical treatment. Its sensitivity is 88% to 90%, and its specificity is 86% to 90%. Not suitable for the crowd There are no special taboos. Adverse reactions and risks There are no related complications and hazards.
