Description:
The H. Pylori Antibody (Ab) Test is a serological test used to detect IgM, IgG, or IgA antibodies against Helicobacter pylori, a bacterium associated with gastritis, peptic ulcers, and gastric cancer. This test helps determine past or current exposure to the infection.

Key Points

Purpose: Identifies immune response to H. pylori infection.

Sample Type: Blood (serum).

Result Interpretation:

IgM Positive → Suggests a recent or active infection.

IgG Positive → Indicates a past or ongoing infection.

IgA Positive → May suggest mucosal immune response.

Clinical Importance: Useful for initial screening but cannot distinguish between past and active infections.

Since antibody tests cannot confirm an active infection, additional tests like the H. Pylori Antigen (Ag) Test, Urea Breath Test (UBT), or Endoscopy with Biopsy are recommended for accurate diagnosis and treatment monitoring. If experiencing persistent digestive symptoms, consult a healthcare provider for further evaluation.H. Pylori Antibody (Ab) Test: Brief Overview
