The Dengue NS1 Antigen Rapid Test is a rapid chromatographic immunoassay for the qualitative detection of dengue virus NS1 antigen in human whole blood, serum or plasma as an aid in the diagnosis of primary and secondary Dengue infections.
Dengue viruses, transmitted by the mosquito, Aedes aegypti and Aedes albopictus mosquitoes, are widely distributed throughout the tropical and subtropical areas of the world. There are four known distinct serotypes (dengue virus 1, 2, 3 and 4). In children, infection is often subclinical or causes a self-limited febrile disease. However, if the patient is infected second times with a different serotype, a more severe disease, dengue hemorrhagic fever or dengue shock syndrome, is more likely to occur. Dengue is considered to be the most important arthropod-borne viral disease due to the human morbidity and mortality it causes. NS1 is a highly-conserved glycoprotein that is present at high concentrations in the sera of dengue-infected patients during the early clinical phase of the disease. NS1 antigen is found from the first day and up to 9 days after onset of fever in sample of primary or secondary dengue infected patients. The Dengue NS1 Ag Test is a rapid test that utilizes a combination of anti-dengue NS1 Ag coated colored particles for the detection of Dengue NS1 antigen in human whole blood, serum, or plasma.
• Rapid Test.
• Buffer
• Disposable pipettes
• Instruction for use.
• Store at 2 ~ 30 º C in the sealed pouch for 24 months.
• Keep away from direct sunlight, moisture and heat.
• DO NOT FREEZE
Sample Collection&Storage
• The kit should be stored at 2-30°C until the expiry date printed on the sealed pouch.
• The test must remain in the sealed pouch until use.
• Keep away from direct sunlight, moisture and heat.
• Do not freeze.
• Care should be taken to protect the components of the kit from contamination. Do not use if there is evidence of microbial contamination or precipitation. Biological contamination of dispensing equipment, containers or reagents can lead to false results.
Bring tests, specimens, buffer and/or controls to room temperature (15- 30°C) before use.
1. Remove the test from its sealed pouch, and place it on a clean, level surface. Label the device with patient or control identification. For best results, the assay should be performed within one hour.
2. Transfer 3 drops of serum/plasma (approximately 75 µL) to the specimen well (S) of the device with the provided disposable pipette, and start the timer.
Allow 2 drops of whole blood (approximately 50 µL) to fall into the center of the specimen well(s) of the test device then add 1 drop of buffer, and start the timer.
Avoid trapping air bubbles in the specimen well (S), and do not add any solution to the result area.
As the test begins to work, color will migrate across the membrane.
3. Wait for the colored band(s) to appear. The result should be read at 10 minutes. Do not interpret the result after 20 minutes.
