Vibrio Cholerae O139 Antigen Rapid Test Device (Feces)

Vibrio cholerae is a gram-negative bacterium linked with cholera, an acute intestinal infection. Epidemic cholera is mainly associated with serogroups O1 and O139, which are important in public health monitoring. The O139 serogroup is clinically important because it has been associated with cholera outbreaks and may cause severe watery diarrhea similar to cholera caused by O1 strains. A Vibrio Cholerae O139 Antigen Rapid Test Device helps detect the O139 antigen quickly, allowing healthcare providers to take appropriate next steps based on clinical symptoms and local guidelines.

• In cholera outbreaks, time is critical. Delayed diagnosis can delay treatment, reporting, and containment measures.
• Rapid testing supports faster screening of suspected cases, early public health response, field-level outbreak monitoring, improved surveillance in high-risk regions, reduced laboratory turnaround time, and better triage in emergency settings.
• Cholera outbreaks can move quickly, especially where drinking water, sanitation, and hygiene systems are disrupted. Rapid diagnostic tools help healthcare workers identify possible cases faster and support immediate clinical and public health action.

The Vibrio Cholerae O139 Antigen Rapid Test Device (Feces) by LARKSOIS Pharma may be used in professional diagnostic and public health environments.

Applications

• Suspected cholera case screening
• Hospitals and clinics
• Diagnostic laboratories
• Emergency outbreak response
• Public health surveillance
• Field screening environments
• Remote and resource-limited settings
• International diagnostic distribution

• The Vibrio Cholerae O139 Antigen Rapid Test Device generally works on a lateral flow immunoassay principle.
• In this method, the prepared fecal specimen migrates across the test membrane.
• If Vibrio cholerae O139 antigen is present in the sample, it reacts with specific antibodies and produces a visible test line.
• A control line appears to confirm that the test has run correctly. The result should always be interpreted according to the official LARKSOIS Pharma product insert.

The Vibrio Cholerae O139 Antigen Rapid Test Device uses a rapid lateral flow / immunochromatographic assay method for qualitative detection of Vibrio cholerae O139 antigen in human fecal specimens.

Benefits

• Rapid detection of Vibrio cholerae O139 antigen
• Feces-based specimen format
• Simple visual interpretation
• No advanced instrument required
• Supports outbreak and surveillance testing
• Suitable for professional diagnostic use
• Useful in hospitals, clinics, laboratories, and field settings
• Designed for international diagnostic supply

The Vibrio Cholerae O139 Antigen Rapid Test Device is designed for human fecal specimens. Proper specimen collection and handling are important because poor collection, delayed testing, contamination, or incorrect procedure may affect results.

Guidance

• Use human fecal specimens only
• Collect fecal specimens in a clean and dry container
• Collect sufficient specimen according to the product insert
• Test specimens as soon as possible after collection when recommended
• Mix the fecal specimen with extraction buffer as instructed
• Avoid contaminated or improperly stored samples
• Read results only within the recommended time window
• Treat all fecal specimens as potentially infectious material

Note

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

The Vibrio Cholerae O139 Antigen Rapid Test Device is designed to detect Vibrio cholerae O139 antigen in fecal specimens. The O139 group is important in cholera outbreak investigation and surveillance. Exact analytical performance, detection limit, cross-reactivity, and interpretation details should be published according to the final product insert, technical file, and regulatory documentation.

• Cholera testing is important because severe cases may lead to rapid dehydration if not managed quickly.
• A positive rapid test result suggests Vibrio cholerae O139 antigen may be present in the fecal specimen and should be interpreted with symptoms, outbreak context, and laboratory confirmation where required.
• A negative result does not always rule out infection, especially if antigen levels are below the detectable level, specimen collection was improper, or testing was performed outside the optimal period.
• Healthcare professionals should interpret results together with clinical findings and public health guidance.

The Vibrio Cholerae O139 Antigen Rapid Test Device is intended as a qualitative screening aid and should not be used as the only basis for diagnosis or treatment decisions.

Instructions

• A positive result suggests Vibrio cholerae O139 antigen detection but does not confirm disease severity
• A negative result does not always rule out cholera infection
• Improper specimen collection or storage may affect results
• Delayed testing may affect antigen detection
• Contaminated or insufficient samples may affect accuracy
• Results should be interpreted with clinical findings and outbreak context
• Confirmatory testing may be required depending on local diagnostic and surveillance guidelines

Instructions

• Rapid detection of Vibrio cholerae O139 antigen
• Feces-based specimen format
• Simple visual interpretation
• No advanced instrument required
• Supports outbreak and surveillance testing
• Suitable for professional diagnostic use
• Helps improve early screening in suspected cholera cases
• Designed for international diagnostic supply

Note

The Vibrio Cholerae O139 Antigen Rapid Test Device by LARKSOIS Pharma is developed for professional users who need fast and practical infectious disease screening support.

Steps

• Bring the test device, specimen, and buffer to the recommended testing condition if required
• Open the sealed pouch only when ready to test
• Collect the fecal specimen according to the product insert
• Mix the fecal specimen with the provided extraction buffer as instructed
• Apply the prepared specimen to the test cassette
• Wait for the test reaction to complete within the stated time
• Read the result within the approved 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 Vibrio Cholerae O139 Antigen Rapid Test Device (Feces).

Positive

A positive result usually shows both the control line and test line. This suggests that Vibrio cholerae O139 antigen may be present in the fecal specimen. The result should be interpreted with symptoms, outbreak context, and other laboratory findings.

Negative

A negative result usually shows the control line only. This suggests that Vibrio cholerae O139 antigen was not detected or was below the test detection level at the time of testing. A negative 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 device and properly prepared fecal specimen according to the product insert.

Instructions

• Store the test device according to the product label instructions
• Keep the test cassette sealed until use
• Protect from moisture, heat, and direct sunlight
• Do not use expired or damaged test kits
• Use clean specimen collection materials
• Read results within the recommended time window
• Follow the temperature range mentioned on the product label

Instructions

• For professional in-vitro diagnostic use only
• Use human fecal specimens only
• Do not reuse the test device
• Follow biosafety precautions
• Read results within the recommended time window
• Negative results do not fully rule out infection
• Positive results should be correlated with clinical symptoms and confirmatory testing when needed
• Follow laboratory biosafety and disposal procedures
