Introduction
The Helicobacter pylori delta value refers to the change in IgG antibody levels in Helicobacter pylori antibody testing, and is one of the indicators used to assess H. pylori infection status. A negative delta value indicates a decrease in IgG antibody levels, suggesting that the H. pylori infection has been controlled or successfully treated. If the patient still experiences symptoms such as stomach pain or indigestion, further examination is recommended.
The Helicobacter pylori delta value refers to the change in IgG antibody levels in Helicobacter pylori antibody testing and is one of the indicators used to assess H. pylori infection status. A negative delta value indicates a decrease in IgG antibody levels, suggesting that the H. pylori infection has been controlled or successfully treated. Details are as follows:
Helicobacter pylori is a common gastrointestinal pathogen; infection can lead to diseases such as gastritis and peptic ulcers. Diagnosis of H. pylori infection relies primarily on clinical symptoms and laboratory tests, including breath tests, serological testing, and endoscopy. Among these, H. pylori antibody testing is a commonly used method that evaluates infection status by measuring levels of antibodies such as IgG, IgA, and IgM.
A negative H. pylori delta value indicates that the infection has been controlled or cured. However, it should be noted that the rate of delta value change is influenced by factors such as the severity of the infection and the treatment regimen; therefore, the delta value alone should not be used to determine treatment efficacy. If patients continue to experience symptoms such as stomach pain or indigestion, further evaluation and treatment are recommended.
