Norovirus GI/GII Rapid Test Device (Feces)

The Norovirus GI/GII Rapid Test Device is a stool-based rapid test used to detect norovirus antigens. Norovirus has multiple genogroups, but GI and GII are the most important genogroups associated with human gastroenteritis. A GI/GII test helps screen for the main clinically relevant norovirus groups in one rapid device.

• Norovirus is one of the most common causes of acute gastroenteritis worldwide.
• It can spread quickly through contaminated food, water, surfaces, and close contact with infected people.
• Fast screening is useful for infection-control planning, patient management, and outbreak response.
• Common symptoms may include vomiting, diarrhea, stomach cramps, nausea, fever, and body aches.

The Norovirus GI/GII Rapid Test Device by LARKSOIS Pharma may be used in professional diagnostic, gastroenteritis screening, and public health environments.

Applications

• Hospitals and clinics
• Diagnostic laboratories
• Gastroenteritis screening programs
• Childcare and school health settings
• Elderly care facilities
• Foodborne outbreak investigations
• Travel and cruise-related illness screening
• Public health surveillance support
• International diagnostic distribution

• The Norovirus GI/GII Rapid Test Device works on lateral flow immunochromatographic assay technology.
• A fecal specimen is collected and prepared with extraction buffer.
• The processed sample is then added to the test device.
• If Norovirus GI or GII antigen is present, it reacts with specific antibodies on the membrane and forms visible test lines.
• A control line confirms correct sample migration and valid test performance.

The Norovirus GI/GII Rapid Test Device uses rapid lateral flow immunochromatographic technology for qualitative detection of Norovirus GI and GII antigens in human fecal specimens.

Benefits

• Detects Norovirus GI antigen
• Detects Norovirus GII antigen
• Uses fecal specimens
• Rapid visual result
• Simple test procedure
• No complex instrument required
• Useful for gastroenteritis screening
• Supports outbreak-response workflows

The Norovirus GI/GII Rapid Test Device is designed for human fecal specimens. Correct stool collection, extraction, and handling are important for reliable rapid test performance.

Guidance

• Use approved fecal specimens only
• Collect specimens according to the product insert
• Use clean and suitable stool collection materials
• Avoid contaminated or improperly stored samples
• Mix the fecal specimen with extraction buffer correctly
• Apply the processed sample properly to the test device
• Read results only within the recommended time window
• Handle all fecal specimens according to laboratory safety procedures

Note

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

The Norovirus GI/GII Rapid Test Device by LARKSOIS Pharma is designed for qualitative detection of Norovirus Genogroup I and Genogroup II antigens in human fecal specimens. Detection of GI or GII antigen may support rapid screening of suspected norovirus-related gastroenteritis.

• A positive result means Norovirus GI or GII antigen has been detected in the fecal specimen.
• The result should be interpreted with symptoms, exposure history, and outbreak context.
• A negative result does not completely rule out norovirus infection if symptoms or outbreak suspicion remain high.
• Molecular testing such as RT-PCR may be recommended for outbreak confirmation or when clinical suspicion remains high.

The Norovirus GI/GII Rapid Test Device is a useful professional screening aid, but molecular testing is generally preferred for outbreak confirmation. Rapid antigen tests may be affected by sample quality, timing of collection, viral load, and test procedure.

Instructions

• For professional in-vitro diagnostic use only
• Use approved fecal specimens only
• Improper specimen collection may affect results
• False positive or false negative results may occur
• Antigen tests should not replace RT-qPCR during outbreak investigations
• Molecular testing may be recommended when suspicion remains high
• Read results only within the recommended time
• Follow the official product insert carefully

Instructions

• Detects Norovirus GI and GII antigens
• Uses fecal specimens
• Rapid visual result
• Simple test procedure
• No complex instrument required
• Useful for gastroenteritis screening
• Supports outbreak-response workflows
• Suitable for international diagnostic supply

Note

The Norovirus GI/GII Rapid Test Device by LARKSOIS Pharma is designed for fast, practical, and accessible norovirus screening support.

Steps

• Bring the test device, fecal specimen, and extraction buffer to room temperature
• Collect the fecal specimen according to the instructions
• Prepare the stool sample with extraction buffer
• Mix the sample properly as instructed in the product insert
• Remove the test cassette from the sealed pouch
• Apply the processed sample to the sample well
• Wait for the recommended reaction time
• Read the test and control lines within the valid time window
• 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 Norovirus GI or GII antigen has been detected in the fecal specimen. The result should be interpreted with symptoms, exposure history, and outbreak context.

Negative

A negative result means norovirus antigen was not detected at the test’s detectable level. If symptoms or outbreak suspicion remain high, molecular testing such as RT-PCR may be recommended.

Invalid

If the control line does not appear, the result is invalid. Testing should be repeated with a new device.

Instructions

• Store the Norovirus GI/GII 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

• For professional in-vitro diagnostic use only
• Handle fecal specimens carefully
• Wear gloves and protective equipment during testing
• Do not reuse the test cassette
• Avoid specimen contamination
• Do not use damaged or expired kits
• Read results only within the recommended time
• Interpret results with symptoms and outbreak context
