HBsAg/HCV/HIV/Syphilis Combo Rapid Test Cassette

• HBsAg – Hepatitis B Surface Antigen: HBsAg is a marker used in screening for Hepatitis B Virus infection. The HBsAg section helps detect Hepatitis B surface antigen in the specimen.
• HCV Antibodies: The HCV section detects antibodies to Hepatitis C Virus. HCV screening is important because Hepatitis C can affect liver health and may remain undetected without testing.
• HIV 1/2 Antibodies: The HIV section detects antibodies to HIV type 1 and type 2. It supports screening workflows, but final diagnosis should follow approved clinical and laboratory protocols.
• Syphilis Antibodies: The syphilis section detects antibodies to Treponema pallidum, the bacterium associated with syphilis.

• Infectious diseases such as Hepatitis B, Hepatitis C, HIV, and syphilis are major global public health concerns.
• Many infections may not show obvious symptoms in early stages, which makes screening important in healthcare systems.
• A multi-marker rapid test cassette can help streamline testing operations, reduce handling complexity, support early identification of reactive samples, and reduce dependency on equipment-based testing for initial screening.
• The HBsAg/HCV/HIV/Syphilis Combo Rapid Test Cassette is useful where fast, simple, and visual screening is required.

The HBsAg/HCV/HIV/Syphilis Combo Rapid Test Cassette by LARKSOIS Pharma may be used in professional diagnostic and healthcare environments.

Applications

• Multi-marker infectious disease screening
• Hospitals and clinical laboratories
• Diagnostic centers and clinics
• Blood screening support programs
• Public health testing programs
• Point-of-care testing workflows
• International diagnostic distribution
• Healthcare procurement and supply channels

• The HBsAg/HCV/HIV/Syphilis Combo Rapid Test Cassette works on a rapid chromatographic immunoassay principle.
• The specimen moves across the test membrane by capillary action.
• If the target antigen or antibodies are present, colored test lines appear in the relevant test region.
• A control line confirms that the test has worked properly. Results should always be read according to the official LARKSOIS Pharma product insert.

The HBsAg/HCV/HIV/Syphilis Combo Rapid Test Cassette uses rapid chromatographic immunoassay technology for qualitative detection of HBsAg, HCV antibodies, HIV 1/2 antibodies, and syphilis antibodies.

Benefits

• Detects four infectious disease markers in one cassette
• Suitable for whole blood, serum, or plasma specimens
• Rapid visual result interpretation
• No major instrument required
• Designed for professional in-vitro diagnostic use
• Useful for hospitals, labs, clinics, and public health screening
• Supports fast preliminary screening decisions
• Convenient for international medical supply and diagnostic distribution

The HBsAg/HCV/HIV/Syphilis Combo Rapid Test Cassette is designed for whole blood, serum, or plasma specimens. Correct specimen collection and handling are important for reliable screening performance.

Guidance

• Use whole blood, serum, or plasma specimens only
• Collect specimens according to the product insert
• Use clean and suitable specimen collection materials
• Avoid contaminated or improperly stored samples
• Bring the test cassette, specimen, and buffer to room temperature if required
• Apply the required specimen and buffer as instructed
• Read results only within the recommended time window
• Treat all specimens as potentially infectious material

Note

Specimen collection, handling, timing, and storage should always follow the official LARKSOIS Pharma kit insert.

Instructions

• HBsAg – Hepatitis B surface antigen
• HCV Ab – Antibodies to Hepatitis C Virus
• HIV 1/2 Ab – Antibodies to HIV type 1 and type 2
• Syphilis Ab – Antibodies to Treponema pallidum

Note

Exact performance characteristics, sensitivity, specificity, cross-reactivity, and interpretation details should follow the final product insert and technical documentation.

• HBsAg, HCV, HIV, and syphilis screening is important because these infections may have serious health consequences and may remain undetected without testing.
• A combo cassette can help healthcare professionals screen multiple markers in a single rapid test format.
• Reactive results should not be treated as final diagnosis. They should be confirmed using approved laboratory methods and interpreted with clinical history, exposure risk, and local diagnostic guidelines.
• Healthcare professionals should decide diagnosis, counseling, and follow-up based on complete clinical evaluation.

The HBsAg/HCV/HIV/Syphilis Combo Rapid Test Cassette is intended as a qualitative screening aid and should not be used as the only basis for diagnosis or treatment decisions.

Instructions

• Reactive results are preliminary and require further testing where applicable
• Non-reactive results do not always rule out infection
• Testing too early after exposure may affect detection
• Improper specimen collection or storage may affect results
• Expired or poorly stored kits may affect performance
• Results should be interpreted with clinical findings and risk assessment
• Confirmatory testing should be performed according to local diagnostic guidelines

Instructions

• Detects four infectious disease markers in one cassette
• Suitable for whole blood, serum, or plasma
• Rapid visual result interpretation
• No major instrument required
• Designed for professional in-vitro diagnostic use
• Useful for hospitals, labs, clinics, and public health screening
• Supports fast preliminary screening decisions
• Convenient for international medical supply and diagnostic distribution

Note

The HBsAg/HCV/HIV/Syphilis Combo Rapid Test Cassette by LARKSOIS Pharma is developed for professional users who need fast and practical infectious disease screening support.

Steps

• Bring the test cassette, specimen, and buffer to room temperature if required
• Remove the cassette from the sealed pouch only when ready to test
• Place the test cassette on a clean, flat surface
• Add the required amount of whole blood, serum, or plasma into the sample well
• Add buffer as instructed in the product insert
• Wait for the recommended reaction time
• Read the result within the stated interpretation window
• Dispose of used materials according to laboratory safety rules

Note

The exact procedure must follow the official LARKSOIS Pharma product insert supplied with the HBsAg/HCV/HIV/Syphilis Combo Rapid Test Cassette.

Positive

A reactive or positive result usually shows a test line in the relevant disease marker area along with the control line. This suggests that the specific target marker may be present. Reactive results should be confirmed using approved laboratory methods.

Negative

A non-reactive or negative result usually shows only the control line. This suggests that the target marker was not detected at the time of testing. A non-reactive result does not always rule out infection.

Invalid

If the control line does not appear, the result is invalid. The test should be repeated with a new cassette and properly collected specimen according to the product insert.

Instructions

• Store according to the product label and package insert
• Store in a dry place
• Keep cassette sealed until use
• Avoid direct sunlight
• Do not freeze
• Do not use after expiry date
• Keep away from moisture and heat
• Use immediately after opening the pouch

Instructions

• For professional in-vitro diagnostic use only
• Do not reuse the test cassette
• Handle all specimens as potentially infectious
• Wear gloves and follow biosafety procedures
• Do not mix components from different lots
• Do not use damaged or expired kits
