HIV Ab/Ag G4 Rapid Test Device (WB/S/P)

The HIV Ab/Ag G4 Rapid Test Device is a 4th generation HIV screening test designed to detect two important HIV markers: HIV antibodies produced by the immune system after exposure and HIV-1 p24 antigen, a viral protein that may appear earlier than antibodies.

• 4th generation HIV tests are important because they detect both HIV antibodies and HIV-1 p24 antigen.
• Detection of p24 antigen may support earlier HIV screening compared with antibody-only tests.
• Rapid HIV screening supports public health programs, healthcare screening, blood safety programs, and clinical evaluation workflows.
• Early HIV detection may help individuals access confirmatory testing, counseling, treatment, and prevention services sooner.

The HIV Ab/Ag G4 Rapid Test Device by LARKSOIS Pharma may be used in professional diagnostic and healthcare screening environments.

Applications

• Hospital and clinic HIV screening
• Diagnostic laboratory testing
• Public health HIV programs
• Blood donor screening support
• Emergency screening programs
• Community healthcare campaigns
• STI and infectious disease clinics
• Point-of-care HIV screening
• International diagnostic distribution

• The HIV Ab/Ag G4 Rapid Test Device works using lateral flow immunochromatographic assay technology.
• When the specimen is added, it migrates across the test membrane by capillary action.
• If HIV antibodies or HIV-1 p24 antigen are present, they bind with coated reagents and produce visible test lines.
• A control line confirms proper sample migration and valid test performance.

The HIV Ab/Ag G4 Rapid Test Device uses rapid lateral flow immunochromatographic technology for qualitative detection of HIV antibodies and HIV-1 p24 antigen in whole blood, serum, or plasma specimens.

Benefits

• Detects HIV antibodies and HIV-1 p24 antigen
• 4th generation rapid HIV test format
• Suitable for whole blood, serum, and plasma
• Rapid visual result
• No complex instrument required
• Useful for professional screening programs
• Supports earlier detection compared with antibody-only tests
• Practical point-of-care diagnostic application

The HIV Ab/Ag G4 Rapid Test Device supports whole blood, serum, and plasma specimens. This flexibility helps support different healthcare workflows and screening environments.

Guidance

• Use approved whole blood, serum, or plasma specimens only
• Collect specimens according to the product insert
• Use clean and suitable sample collection materials
• Avoid contaminated or improperly stored samples
• Apply the specimen correctly to the sample area
• Add buffer according to instructions
• Read results only within the recommended time window
• Handle all blood specimens as potentially infectious material

Note

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

The HIV Ab/Ag G4 Rapid Test Device by LARKSOIS Pharma is designed for qualitative detection of HIV-1/2 antibodies and HIV-1 p24 antigen in whole blood, serum, or plasma specimens. Detection of either marker may suggest HIV exposure and should be followed by confirmatory testing according to clinical guidelines.

• 4th generation HIV screening supports earlier detection compared with many antibody-only tests.
• Detection of HIV-1 p24 antigen may help reduce the diagnostic window period.
• Rapid HIV screening supports public health programs, healthcare campaigns, and clinical workflows.
• Reactive results should always be confirmed according to local HIV testing algorithms and institutional guidelines.

The HIV Ab/Ag G4 Rapid Test Device is a screening aid and should not be used as the only basis for diagnosis or treatment decisions. Results should be interpreted with clinical findings, exposure history, and confirmatory laboratory testing when required.

Instructions

• For professional in-vitro diagnostic use only
• Handle all blood specimens as potentially infectious
• Wear gloves during sample handling
• Do not reuse the test device
• Avoid cross-contamination
• Do not use damaged or expired kits
• Read results only within the recommended time
• Confirm reactive results according to healthcare guidelines

Instructions

• Detects HIV antibodies and HIV-1 p24 antigen
• 4th generation rapid HIV test format
• Suitable for whole blood, serum, and plasma
• Rapid visual result
• No complex instrument required
• Useful for professional screening programs
• Supports earlier detection compared with antibody-only tests
• Suitable for international healthcare supply

Note

The HIV Ab/Ag G4 Rapid Test Device by LARKSOIS Pharma provides practical and accessible HIV screening support for professional healthcare environments.

Steps

• Bring the test device, specimen, and buffer to room temperature
• Open the sealed pouch only when ready to test
• Place the test cassette on a clean and flat surface
• Add whole blood, serum, or plasma to the sample well
• Add buffer according to the instructions for use
• Wait for the recommended reaction time
• Read the test and control lines within the valid time window
• Do not interpret results after the recommended reading time
• Dispose of used materials according to laboratory safety procedures

Note

Testing should be performed by trained healthcare professionals according to the official LARKSOIS Pharma product insert.

Positive

A positive or reactive result means HIV antibodies and/or HIV-1 p24 antigen were detected. Reactive results should be confirmed according to national or institutional HIV testing guidelines.

Negative

A negative result means HIV antibodies or p24 antigen were not detected at the test’s detectable level. If recent exposure is suspected, repeat testing may be recommended after the window period.

Invalid

If the control line does not appear, the result is invalid. The test should be repeated using a new test device.
