Diagnosing Hepatitis A Infection
Since Hepatitis A symptoms can be similar to other liver conditions or viral infections, laboratory testing is essential for definitive diagnosis. Blood tests that detect antibodies produced by the immune system in response to the Hepatitis A virus provide reliable confirmation of infection status.
Understanding Your Results
When Hepatitis A antibodies are detected in elevated levels, it confirms exposure to the virus and helps distinguish Hepatitis A from other causes of liver inflammation. This information is crucial for proper medical management and for taking appropriate precautions to prevent transmission to others.
