Human Immunodeficiency Virus (1/2/O) Rapid Test Device (WB/S/P)

The HIV 1/2/O Rapid Test Device is a screening test used to detect antibodies produced by the body in response to HIV infection. The term 1/2/O means the test is intended to detect antibodies related to HIV-1, HIV-2, and HIV-1 subtype O, supporting broader international diagnostic screening.

• The HIV 1/2/O Rapid Test Device supports early identification of individuals who may have been exposed to HIV.
• Early testing helps connect people to counseling, confirmatory testing, treatment, and prevention services.
• Rapid tests are useful in outreach programs, emergency settings, high-volume screening centers, and healthcare facilities where fast results are needed.
• Reactive rapid test results should be confirmed according to approved national testing algorithms.

The HIV 1/2/O Rapid Test Device by LARKSOIS Pharma may be used in professional diagnostic and healthcare screening environments.

Applications

• Hospitals and diagnostic laboratories
• Public health screening programs
• Community healthcare campaigns
• STI and infectious disease clinics
• Blood bank screening support
• Pre-surgical screening support
• Occupational health testing
• International diagnostic distributors
• Medical procurement agencies

• The Human Immunodeficiency Virus (1/2/O) Rapid Test Device works on the principle of lateral flow immunochromatographic assay.
• When the specimen is added to the sample well, it migrates through the test membrane by capillary action.
• If HIV antibodies are present, they bind with recombinant HIV antigens and generate a visible test line.
• A control line confirms that the sample migration and test procedure have worked correctly.

The HIV 1/2/O Rapid Test Device uses rapid lateral flow immunochromatographic technology for qualitative detection of HIV-1, HIV-2, and HIV-1 subtype O antibodies in whole blood, serum, or plasma specimens.

Benefits

• Rapid HIV antibody screening
• Qualitative detection of HIV-1 antibodies
• Qualitative detection of HIV-2 antibodies
• Supports HIV-1 subtype O antibody detection
• Suitable for whole blood, serum, or plasma
• Simple visual result interpretation
• Useful for professional screening programs
• Practical point-of-care diagnostic format

The HIV 1/2/O Rapid Test Device supports whole blood, serum, and plasma specimens. This flexibility helps healthcare providers use the most suitable specimen type based on testing environment, laboratory workflow, and available resources.

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 well
• 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 1/2/O Rapid Test Device by LARKSOIS Pharma is designed for qualitative detection of antibodies to HIV-1, HIV-2, and HIV-1 subtype O in whole blood, serum, or plasma specimens. Detection of HIV antibodies may suggest exposure to HIV and should be followed by confirmatory testing according to clinical guidelines.

• A positive result means antibodies to HIV-1, HIV-2, or subtype O have been detected.
• A reactive rapid test is not a final diagnosis and should be confirmed with approved follow-up testing.
• Laboratory antigen/antibody tests may detect infection earlier than many rapid antibody-only tests because some laboratory tests also detect p24 antigen.
• Healthcare professionals should interpret results with timing after exposure, risk profile, clinical findings, and national testing guidelines.

The HIV 1/2/O Rapid Test Device is a professional screening tool and should not be used as the only basis for diagnosis or treatment decisions. Reactive results should be followed by confirmatory testing as per local clinical and regulatory guidelines.

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 approved testing algorithms

Instructions

• Detects antibodies to HIV-1
• Detects antibodies to HIV-2
• Supports HIV-1 subtype O antibody detection
• Suitable for whole blood, serum, or plasma
• Rapid visual result
• Simple professional testing workflow
• Useful for international diagnostic supply
• Practical point-of-care screening format

Note

The HIV 1/2/O Rapid Test Device by LARKSOIS Pharma provides a practical screening solution for hospitals, laboratories, NGOs, public health programs, distributors, and procurement teams.

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 result means antibodies to HIV-1, HIV-2, or subtype O have been detected. A reactive rapid test is not a final diagnosis and should be confirmed with approved follow-up testing.

Negative

A negative result means HIV antibodies were not detected at the test’s detectable level. If exposure was recent, repeat testing or laboratory-based testing may be needed after the window period.

Invalid

If the control line does not appear, the test is invalid. A fresh test device should be used according to the product insert.

Instructions

• Store the HIV 1/2/O Rapid Test Device according to the product label and insert
• Store in a cool and dry place
• Keep sealed until use
• Protect from heat, sunlight, and moisture
• Do not freeze unless specified
• Do not use expired kits
• Use immediately after opening the pouch
• Follow all instructions for use carefully

Instructions
