About this service

Hepatitis B Surface Antigen (HBs Ag) analysis is a reliable test used to detect the presence of the Hepatitis B virus surface antigen in the blood. The presence of this antigen indicates an active infection with the virus, meaning the person could potentially transmit the infection to others. This test is one of the key examinations for diagnosing Hepatitis B and can help determine the stage of the infection, whether acute or chronic. It is recommended for individuals at risk of infection, such as healthcare workers, those living with an infected person, or those experiencing symptoms of hepatitis. The test is an important tool for guiding treatment decisions and monitoring liver health.

Purpose Test

Presence of Hepatitis B Virus Antigen: It measures the levels of the hepatitis B surface antigen in the blood, indicating an active infection with the virus.
Determining the Type of Infection: It helps determine whether the infection is acute (recent) or chronic (long-term).
Assessing the Risk of Transmission: The presence of HBs Ag is a sign that the person may transmit the infection to others.
Guiding Treatment: The results help doctors determine the need for treatment and appropriate monitoring of liver health.

Recommended groups

At-Risk Individuals: Such as healthcare providers and medical workers who handle blood or infected bodily fluids.
Individuals Living with an Infected Person: It is recommended for people living with hepatitis B patients for early detection and prevention.
People with a History of Previous Infection: To determine if the infection is still active.
Pregnant Women: To determine if the woman is a carrier of the virus and assess potential risks to the newborn.
Individuals with Hepatitis Symptoms: Such as fatigue, weight loss, abdominal pain, and jaundice.
People Receiving Treatment for Liver Problems: To evaluate the viral status and monitor disease progression.
Blood Donors: Since HBs Ag testing is part of routine screenings to confirm the absence of infection.
Individuals Seeking Health Insurance: In some cases, insurance may require this analysis as part of routine health checkups.

Symptoms indicative

General Fatigue: Persistent feeling of tiredness or weakness without a clear cause.
Unexplained Weight Loss: Significant weight loss without following a diet or exercising.
Nausea or Vomiting: Persistent nausea or the need to vomit.
Abdominal Pain: Especially in the upper right area where the liver is located.
Yellowing of Skin or Eyes: The appearance of yellowing in the skin or in the whites of the eyes, indicating jaundice.
Dark Urine: Urine becoming darker in color.
Light-colored Stool: Appearance of pale or light-colored stool.
Itchy Skin: Persistent itching of the skin.
Arthritis: Pain or swelling in the joints.

Normal Levels

Negative Results: If the result is negative, it means that the Hepatitis B surface antigen (HBs Ag) is not present in the blood, indicating no active infection. This result suggests that the person is either not infected with the virus or has recovered from it.
Positive Results: If the result is positive, it means that the HBs Ag antigen is present in the blood, indicating an active Hepatitis B infection. The infection can be either acute (recent) or chronic (long-term), requiring further evaluation to determine the stage of the infection.
