HBsAg Rapid Test Device/Strip (WB/S/P)

HBsAg stands for Hepatitis B Surface Antigen. It is a protein found on the surface of the Hepatitis B Virus (HBV). Detection of HBsAg in blood may indicate active hepatitis B infection and is commonly used in hepatitis B screening programs.

• The HBsAg Rapid Test Device/Strip helps healthcare professionals screen for possible hepatitis B infection quickly.
• Hepatitis B is a viral liver infection that may lead to serious liver disease if not properly monitored.
• Rapid hepatitis B screening supports infection control, blood safety programs, healthcare screening, and public health monitoring.
• HBsAg testing is commonly used in hospitals, blood banks, laboratories, occupational health programs, and healthcare checkups.

The HBsAg Rapid Test Device/Strip by LARKSOIS Pharma may be used in professional diagnostic and healthcare screening environments.

Applications

• Hepatitis B infection screening
• Blood donor screening support
• Hospital and laboratory testing
• Occupational health screening
• Pre-employment medical screening
• Public health hepatitis programs
• Point-of-care infectious disease testing
• Healthcare checkups
• International diagnostic distribution

• The HBsAg Rapid Test Device/Strip works on a lateral flow immunochromatographic assay principle.
• When whole blood, serum, or plasma is added to the test device, the sample migrates through the membrane.
• If HBsAg is present in the specimen, it reacts with coated antibodies and forms a visible colored test line.
• The control line confirms valid sample migration and correct test performance.

The HBsAg Rapid Test Device/Strip uses rapid lateral flow immunochromatographic technology for qualitative detection of Hepatitis B Surface Antigen in whole blood, serum, or plasma specimens.

Benefits

• Rapid hepatitis B screening
• Qualitative HBsAg detection
• Suitable for whole blood, serum, or plasma
• Simple visual interpretation
• No advanced instrument required
• Supports blood safety screening
• Useful for hospitals and laboratories
• Professional infectious disease application
