Dengue IgG/IgM Test Device (WB/S/P)

The Dengue IgG/IgM Test Device is a rapid immunochromatographic test used to detect two antibody types: IgM antibodies and IgG antibodies. IgM antibodies are commonly associated with a recent or early immune response, while IgG antibodies usually appear later and may remain detectable for a longer period.

• Dengue is a mosquito-borne viral infection that can cause fever, headache, muscle pain, rash, weakness, and in severe cases, bleeding complications or shock.
• Early screening helps clinicians monitor patients and decide whether further laboratory evaluation is needed.
• The Dengue IgG/IgM Test Device supports rapid dengue antibody screening, point-of-care testing, hospital workflows, public health surveillance, and outbreak response support.
• The test helps differentiate IgG and IgM antibody patterns, supporting better clinical interpretation.

The Dengue IgG/IgM Test Device by LARKSOIS Pharma may be used in professional diagnostic and healthcare screening environments.

Applications

• Rapid dengue antibody screening
• Point-of-care testing
• Hospital and clinic workflows
• Public health surveillance
• Outbreak response support
• Differentiation of IgG and IgM antibody patterns
• Screening in dengue-endemic regions
• Diagnostic laboratories
• International infectious disease testing programs

• The Dengue IgG/IgM Test Device works on a lateral flow immunochromatographic assay principle.
• When the specimen is added to the test cassette, it migrates across the membrane by capillary action.
• If dengue IgG or IgM antibodies are present, they bind to test components and produce visible colored lines.
• A control line confirms valid sample flow and proper test performance.

The Dengue IgG/IgM Test Device uses rapid lateral flow immunochromatographic technology for qualitative detection and differentiation of dengue IgG and IgM antibodies from whole blood, serum, or plasma specimens.

Benefits

• Qualitative detection of dengue IgG antibodies
• Qualitative detection of dengue IgM antibodies
• Differentiates IgG and IgM antibody patterns
• Suitable for whole blood, serum, or plasma specimens
• Simple visual result interpretation
• No major instrument required
• Supports professional dengue screening workflows
• Suitable for international infectious disease testing programs

The Dengue IgG/IgM Test Device is designed for whole blood, serum, or plasma specimens. Correct specimen collection and handling are important for reliable test performance.

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
• Add whole blood, serum, or plasma to the sample well
• Add buffer as instructed
• 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 Dengue IgG/IgM Test Device by LARKSOIS Pharma is designed to detect and differentiate dengue IgG and IgM antibodies in whole blood, serum, or plasma specimens. It helps identify antibody response patterns related to dengue infection and supports professional clinical interpretation.

• Dengue IgG/IgM antibody testing can support rapid screening and immune response evaluation.
• IgM positive results may suggest a recent or primary dengue immune response.
• IgG positive results may suggest past dengue exposure, later-stage infection, or previous dengue infection.
• Healthcare professionals should interpret results with symptoms, exposure history, clinical findings, and other laboratory test results.

The Dengue IgG/IgM Test Device is intended as a qualitative antibody screening aid and should not be used as the only basis for diagnosis, treatment, or public health decisions.

Instructions

• IgM may not be detectable immediately after fever starts
• IgG may remain detectable after past infection
• Antibody tests may not detect very early infection before antibodies develop
• Cross-reactivity with related flaviviruses may be possible
• Negative results do not always rule out dengue
• Performance depends on specimen quality and timing of testing
• Incorrect procedure or storage conditions may affect results
• Results should be interpreted with symptoms and clinical findings

Instructions

• Rapid qualitative detection of dengue IgG and IgM antibodies
• Differentiates IgG and IgM antibody patterns
• Suitable for whole blood, serum, or plasma specimens
• Simple visual result interpretation
• No major instrument required
• Supports point-of-care testing
• Useful for hospitals, clinics, laboratories, and public health programs
• Suitable for international infectious disease testing programs

Note

The Dengue IgG/IgM Test Device by LARKSOIS Pharma is developed for professional users who need fast and practical dengue antibody screening support.

Steps

• Bring the test device and specimen to room temperature
• Remove the test cassette from the sealed pouch
• Place the cassette on a clean, flat surface
• Add whole blood, serum, or plasma to the sample well
• Add buffer as instructed
• Wait for the recommended reaction time
• Read the IgG, IgM, and control lines within the stated time window
• Do not interpret the result after the recommended reading time
• Dispose of used materials according to laboratory safety rules

Note

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

Positive

IgM positive / IgG negative may suggest a recent or primary dengue immune response. IgG positive / IgM negative may suggest past dengue exposure, later-stage infection, or previous dengue infection. IgM positive / IgG positive may suggest recent infection, secondary dengue infection, or active immune response.

Negative

IgM negative / IgG negative means no detectable dengue IgG or IgM antibodies were found. If symptoms are present, testing may be too early, and repeat testing or other diagnostic methods may be needed.

Invalid

If the control line does not appear, the test is invalid and should be repeated with a new device according to the product insert.

Instructions

• Store the Dengue IgG/IgM Test Device as directed on the label and product insert
• Store in a dry place
• Keep sealed until use
• Do not freeze
• Protect from moisture and direct sunlight
• Do not use expired kits
• Use immediately after opening pouch
• Follow the storage temperature mentioned on the product label

Instructions

• For professional in-vitro diagnostic use only
• Handle all blood specimens as potentially infectious
• Wear gloves during testing
• Do not reuse the test cassette
• Avoid cross-contamination between samples
• Do not mix kit components from different lots
• Read results only within the recommended time
• Confirm results where clinically required
