RESZON HBsAg RAPID TEST

RESZON HBsAg Rapid Test is a diagnostic tool used to detect Hepatitis B surface antigen (HBsAg) in human whole blood, plasma or serum samples. It helps identify current Hepatitis B virus (HBV) infection.

The test is based on immunochromatography. If HBsAg is present in the sample, it will bind to specific antibodies in the test, producing a visible line on the strip.

HBV is highly infectious and spreads through:

• Blood-to-blood contact – sharing needles, syringes, razors, toothbrushes, or through unsafe blood transfusions.
• Sexual contact – unprotected sex with an infected person (virus is present in semen and vaginal fluids).
• Mother-to-child transmission – during childbirth (a major route in high-prevalence regions).
• Close household contact – through open cuts or sores (less common).

• Individuals who suspect they may have been exposed to Hepatitis B.
• All pregnant women during each pregnancy, preferably in the first trimester, regardless of vaccination status or history of testing.
• People in high-risk groups (e.g., healthcare and emergency response workers exposed to blood or body fluids, people with multiple sexual partners, or Intravenous drug users, people undergoing dialysis or with chronic kidney disease, people with HIV or hepatitis C).

Chronic HBV infection can lead to substantial morbidity and mortality but is detectable before the development of severe liver disease using reliable and inexpensive screening tests. More than half of people with hepatitis B are unaware of their infection status, and approximately 50%–70% of people with acute hepatitis B are asymptomatic. Without testing, people with hepatitis B virus (HBV) infection can unknowingly transmit the virus to others.

Human whole blood, serum, or plasma.

HBsAg may appear in the blood 1 to 9 weeks after exposure. If you test too early, the result may be negative even if infected.

The test provides results within 15–20 minutes.

A positive result indicates that Hepatitis B surface antigen is present, suggesting a current Hepatitis B infection. You should consult a healthcare professional for further testing and confirmation.

A negative result means no detectable HBsAg was found. However, this does not entirely rule out infection, especially in the early window period. Retesting after a few weeks is advised, if you suspect you have been exposed to Hepatitis B infection.

No special preparation is needed. You can eat and drink normally before the test.

Only a small finger prick or blood draw is required. Any discomfort is minimal and short-lived.
