Dengue NS1 Test Device (WB/S/P)

NS1 stands for non-structural protein 1, a dengue virus antigen that can be present in the blood during the early phase of infection. Unlike Dengue IgG/IgM antibody tests, which detect the body’s immune response, the Dengue NS1 Test Device detects a dengue viral antigen. This makes the Dengue NS1 Test Device useful for early testing when a patient has fever, body pain, headache, rash, or other symptoms suggestive of dengue.

• Dengue can progress quickly, especially in areas where mosquito-borne infections are common.
• Early screening helps healthcare providers monitor symptoms, evaluate risk, and recommend further testing when needed.
• The Dengue NS1 Test Device supports early dengue antigen screening, rapid point-of-care testing, outbreak response, hospital workflows, and public health surveillance.
• The test is qualitative and should not be used as the only basis for diagnosis or treatment decisions.

The Dengue NS1 Test Device by LARKSOIS Pharma may be used in professional diagnostic and healthcare screening environments.

Applications

• Early dengue antigen screening
• Rapid point-of-care testing
• Dengue fever outbreak response
• Hospital and clinic testing workflows
• Public health surveillance
• Testing in tropical and subtropical regions
• Fast preliminary result interpretation
• Emergency screening
• International infectious disease screening programs

• The Dengue NS1 Test Device works on a rapid chromatographic immunoassay principle.
• When the specimen is added to the test cassette, it moves across the membrane.
• If Dengue NS1 antigen is present, it reacts with specific antibodies on the test strip and forms a visible colored test line.
• A control line confirms that the test has worked properly.

The Dengue NS1 Test Device uses rapid chromatographic immunoassay technology for qualitative detection of Dengue NS1 antigen from whole blood, serum, or plasma specimens.

Benefits

• Rapid qualitative detection of Dengue NS1 antigen
• Suitable for whole blood, serum, or plasma specimens
• Useful for early dengue screening
• Simple visual result interpretation
• No major instrument required
• Supports point-of-care testing workflows
• Useful for hospitals, clinics, laboratories, and public health programs
• Suitable for international infectious disease screening programs

The Dengue NS1 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 if required by the kit 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 Dengue NS1 Test Device by LARKSOIS Pharma is designed to detect Dengue NS1 antigen in whole blood, serum, or plasma specimens. NS1 antigen may be present during the early phase of dengue infection, making this test useful for early screening when clinically appropriate.

• The Dengue NS1 Test Device is generally most useful in the early phase of dengue illness.
• NS1 testing is commonly preferred in the first few days of fever.
• IgM/IgG antibody testing may become more useful later when clinically required.
• Healthcare professionals should interpret results with symptoms, exposure history, platelet count, hematocrit, and physician evaluation.

The Dengue NS1 Test Device is intended as a qualitative screening aid and should not be used as the only basis for diagnosis, treatment, or public health decisions.

Instructions

• A positive result suggests Dengue NS1 antigen detection
• A negative result does not completely rule out dengue
• Testing too early or too late may affect NS1 antigen detection
• Specimen quality may affect results
• Other dengue tests may be required depending on illness stage
• Platelet count and hematocrit evaluation may be needed
• Results should be interpreted with symptoms and clinical findings
• Confirm results where clinically required

Instructions

• Rapid qualitative detection of Dengue NS1 antigen
• Supports early dengue screening
• Suitable for whole blood, serum, or plasma specimens
• Simple visual result interpretation
• No major instrument required
• Supports point-of-care testing workflows
• Useful for hospitals, clinics, laboratories, and public health programs
• Suitable for international infectious disease screening programs

Note

The Dengue NS1 Test Device by LARKSOIS Pharma is developed for professional users who need fast and practical early dengue screening support.

Steps

• Bring the test device and specimen to room temperature
• Open the sealed pouch and place the cassette on a clean surface
• Add whole blood, serum, or plasma to the sample well
• Add buffer if required by the kit instructions
• Wait for the recommended reaction time
• Read the result within the correct interpretation window
• Do not read results too early or too late
• Dispose of used materials according to laboratory safety rules

Note

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

Positive

A positive result shows both the control line and test line. This means Dengue NS1 antigen was detected in the specimen.

Negative

A negative result shows only the control line. This means NS1 antigen was not detected. However, dengue is not fully ruled out, especially if testing was done too early, too late, or if symptoms strongly suggest dengue.

Invalid

If the control line does not appear, the test is invalid. Repeat testing with a new device according to the product insert.

Instructions

• Store the Dengue NS1 Test Device as instructed on the product label
• Store in a dry place
• Keep sealed until use
• Do not freeze
• Avoid heat and direct sunlight
• Protect from moisture
• Do not use expired kits
• Use immediately after opening the pouch

Instructions

• For professional in-vitro diagnostic use only
• Handle all blood specimens as potentially infectious
• Wear gloves during testing
• Do not reuse the cassette
• Avoid cross-contamination
• Do not use damaged or expired kits
• Follow local disposal rules
• Confirm results where clinically required
