Hepatitis Marker Screen

HAV IgM, HBsAg, HCV Abs Test

This comprehensive medical lab test detects Hepatitis A Virus IgM (HAV IgM), Hepatitis B Surface Antigen (HBsAg), and Hepatitis C Virus Antibodies (HCV Abs). It is essential for diagnosing acute and chronic hepatitis infections, helping individuals assess their liver health and take necessary precautions. This test is ideal for individuals at risk of hepatitis infections, those experiencing liver-related symptoms, or anyone needing routine screening.

Test Purpose

This test is crucial for identifying hepatitis infections early, allowing for timely medical intervention. HAV IgM detects recent Hepatitis A infections, HBsAg identifies active Hepatitis B infections, and HCV Abs determine exposure to Hepatitis C. Early detection helps prevent complications such as liver damage, cirrhosis, and liver cancer. It is also useful for monitoring treatment progress in individuals undergoing hepatitis therapy.

Symptoms That Indicate This Test

• Fatigue and weakness
• Jaundice (yellowing of the skin and eyes)
• Abdominal pain, especially in the upper right side
• Dark urine and pale stools
• Nausea, vomiting, and loss of appetite
• Unexplained weight loss
• Fever and flu-like symptoms
• History of blood transfusions, unprotected sex, or intravenous drug use

Natural Production and Regulation

Hepatitis A, B, and C are viral infections affecting the liver. The immune system produces IgM antibodies in response to Hepatitis A infection, indicating recent exposure. HBsAg is a protein found on the surface of the Hepatitis B virus, signaling an active infection. HCV Abs are antibodies produced by the immune system after exposure to Hepatitis C, though their presence does not confirm an active infection. The liver plays a vital role in detoxification, metabolism, and immune function, making early detection of hepatitis infections essential for maintaining overall health.

Risks of Untreated Conditions

Ignoring abnormal test results can lead to severe liver complications. Untreated Hepatitis A can cause acute liver failure in rare cases. Chronic Hepatitis B and C infections increase the risk of liver cirrhosis, liver failure, and hepatocellular carcinoma (liver cancer). Additionally, untreated hepatitis infections can be transmitted to others, making early diagnosis and treatment essential for public health.

Test Preparation Instructions

• No fasting is required for this test
• Avoid alcohol consumption for at least 24 hours before the test
• Inform your healthcare provider about any medications or supplements you are taking
• A blood sample will be collected from a vein in your arm

Test Details

• Test Method: Enzyme Immunoassay (EIA) or Chemiluminescent Immunoassay (CLIA)
• Accuracy: High sensitivity and specificity for detecting hepatitis infections

General Package

This test falls under the category of infectious disease screening and liver health assessment. It is recommended for individuals at risk of hepatitis infections, healthcare workers, travelers to high-risk areas, and those with a history of liver disease.
