Hepatitis B and C testing?


Hello Doctor: A year ago, our school arranged for us to undergo a health check, and my HBsAg was negative and HBsAb was negative.
However, I recently went to the hospital for an ultrasound examination, and the doctor said I have mild fatty liver and rough liver surface.
He advised me to get tested for hepatitis B or C.
Is the test I had a year ago still valid, or should I get tested again?

When it comes to understanding Hepatitis B and C testing, especially in the context of a recent diagnosis of fatty liver, it is essential to consider several factors regarding the reliability of previous tests and the implications of your current health status.

Firstly, the tests you underwent a year ago, which showed negative results for both HBsAg (Hepatitis B surface antigen) and HBsAb (Hepatitis B surface antibody), indicate that you were not infected with Hepatitis B at that time and did not have immunity to it. However, it is important to note that the absence of infection or immunity a year ago does not guarantee that you have not been exposed to the virus since then. Hepatitis B can be transmitted through blood and bodily fluids, and if you have had any potential exposure since your last test, it would be prudent to undergo testing again.

Regarding Hepatitis C, the testing is typically done through the detection of antibodies (Anti-HCV). If you have not been tested for Hepatitis C previously, it is advisable to do so, especially since you have been diagnosed with fatty liver. Fatty liver disease can sometimes be associated with viral hepatitis, and it is crucial to rule out any underlying viral infections that could exacerbate liver issues.

Now, concerning your diagnosis of mild fatty liver and the mention of a rough liver surface, these findings can be indicative of liver health issues, including non-alcoholic fatty liver disease (NAFLD) or other liver conditions. Fatty liver itself is characterized by the accumulation of fat in liver cells, which can be caused by various factors, including obesity, diabetes, high cholesterol, and excessive alcohol consumption. While mild fatty liver may not cause significant harm initially, it can progress to more severe liver conditions, such as steatohepatitis, fibrosis, or cirrhosis, if not managed properly.

Given your current situation, it is advisable to follow your doctor's recommendations and undergo the necessary tests for Hepatitis B and C. Additionally, monitoring liver function through tests such as liver enzymes (GOT/GPT), triglycerides, and cholesterol levels is essential. These tests can provide insight into how well your liver is functioning and whether there are any signs of liver damage or disease progression.

In summary, while your previous tests indicated no Hepatitis B infection or immunity, it is crucial to retest for both Hepatitis B and C, especially given your recent diagnosis of fatty liver. Regular monitoring and lifestyle modifications, such as maintaining a healthy weight, engaging in regular physical activity, and following a balanced diet, can significantly impact your liver health. If you have any further questions or concerns, it is always best to consult with your healthcare provider for personalized advice and management strategies.
