Rapid Diagnostic Dengue IgG/IgM/NS1 Combo Rapid Test Kit 15 Min Cassette Type
【INTENDED USE】
The Dengue NS1 & IgG/IgM Rapid Test Combo is a rapid chromatographic immunoassay for the qualitative detection of dengue virus NS1 antigen, IgG and IgM antobody in human whole blood, serum, or plasma as an aid in the diagnosis of primary and secondary Dengue infections.
【INTRODUCTION】
Dengue virus is an enveloped, single-stranded, positive-sense RNA virus that comprises four related but distinct serotypes (Den 1, 2, 3, and 4). The virus is transmitted by mosquitoes of the daytime-biting Stegomyia family, principally Aedes aegypti and Aedes albopictus. Today, more than 2.5 billion people living in the areas of tropical Asia, Africa, Australia and the Americas are at risk for dengue infection. An estimated 100 million cases of dengue fever and 250,000 cases of lifethreatening dengue hemorrhagic fever occur annually on a worldwide basis. Serological detection is a common method for the diagnosis of infection with dengue virus. IgM anti-dengue virus starts to appear at 3 days after initial exposure and remains in circulation for about 30- 60 days. IgG anti-dengue virus is raised at around 7 days, peaks at 2- 3 weeks and persists for the duration of life4-6. Detection of antigens released during virus replication in the infected patient show very promising results; it enables diagnosis from the first day after the onset of fever up to day 9 once the clinical phase of the disease is over, thus, allowing early detection and prompt treatment. The Dengue Ag NS1-IgM/IgG rapid test detects IgG and IgM anti- dengue virus and circulating dengue antigen in one test within 20 minutes. The test is user friendly, does not require cumbersome laboratory equipment and requires
【PRINCIPLE】
The Dengue IgG/IgM Rapid Test Cassette(Whole Blood/Serum/Plasma) is a qualitative membrane- based immunoassay for the detection of Dengue antibodies in whole blood, serum, or plasma. This test consists of two components, an IgG component and an IgM component. In the IgG component, anti-human IgG is coated in IgG test line region. During testing, the specimen reacts with Dengue antigen-coated particles in the test cassette. The mixture then migrates upward on the membrane chromatographically by capillary action and reacts with the anti-human IgG in IgG test line region. If the specimen contains IgG antibodies to Dengue, a colored line will appear in IgG test line region. In the IgM component, anti-human IgM is coated in IgM test line region. During testing, the specimen reacts with anti-human IgM. Dengue IgM antibodies, if present in the specimen, reacts with the anti- human IgM and the Dengue antigen-coated particles in the test cassette, and this complex is captured by the anti-human IgM, forming a colored line in IgM test line region.
Therefore, if the specimen contains Dengue IgG antibodies, a colored line will appear in IgG test line region. If the specimen contains Dengue IgM antibodies, a colored line will appear in IgM test line region. If the specimen does not contain Dengue antibodies, no colored line will appear in either of the test line regions, indicating a negative result. To serve as a procedural control, a colored line will always appear in the control line region, indicating that the proper volume of specimen has been added and membrane wicking has occurred.
The Dengue NS1 Rapid Test Cassette(Whole Blood/Serum/Plasma) is a qualitative membrane- based immunoassay for the detection of Dengue NS1 antigen in whole blood, serum, or plasma. During testing, the specimen reacts with Dengue antibody-conjugate in the test cassette. The Gold antibody conjugate will bind to Dengue antigen in the specimen sample which in turn will bind with Anti-Dengue NS1 coated on the membrane. As the reagent moves across the membrane, the Dengue NS1 antibody on the membrane will bind the antibody-antigen complex causing pale or dark pink line to form at the test line region of the test membrane. The intensity of the lines will vary depending upon the amount of antigen present in the sample. The appearance of pink line in the test region should be considered as positive result.

What are 7 warning signs of dengue? |
Warning Signs*
Abdominal pain or tenderness.
Persistent vomiting.
Clinical fluid accumulation.
Mucosal bleed.
Lethargy or restlessness.
Liver enlargement > 2 cm.
Laboratory finding of increasing HCT concurrent with rapid decrease in platelet count. |
| 2 |
How long will dengue fever last? |
How Long Does Dengue Fever Last? Symptoms can start anywhere from 4 days to 2 weeks after being bitten by an infected mosquito, and typically last for 2 to 7 days. |
| 3 |
What is the best treatment for dengue? |
Most cases of dengue fever can be treated at home with pain medicine. Acetaminophenparacetamol is often used to control pain. Non-steroidal anti-inflammatory drugs like ibuprofen and aspirin are avoided as they can increase the risk of bleeding. For people with severe dengue, hospitalization is often needed. |
| 4 |
Is dengue very serious? |
Severe dengue fever can cause internal bleeding and organ damage. Blood pressure can drop to dangerous levels, causing shock. In some cases, severe dengue fever can lead to death. Women who get dengue fever during pregnancy may be able to spread the virus to the baby during childbirth. |
| 5 |
How do you confirm dengue? |
If an infection is suspected, you will get a blood test to check for the dengue virus. During a blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. |
| 6 |
What not to eat in dengue? |
It is best to choose a lighter diet and avoid oily and fried food. It contains a lot of fat which may lead to higher blood pressure. This can hamper your recovery as it weakens the immune system. |
| 7 |
What is the danger period of dengue? |
Dengue in the critical phase occurs from the 4th to the 7th day since the patient shows symptoms of fever. At this time, the patient may not have a fever or reduce his fever, so he will appear subjective and do not go to the hospital for treatment, making the disease more dangerous. |
| 8 |
Can dengue recover by itself? |
Dengue fever usually lasts between 2 to 7 days.
Most people recover from dengue infection without requiring hospital admission. |
| 9 |
What kills dengue virus? |
To fight the infection, the immune system produces antibodies to neutralize the dengue viral particles, and the complement system is activated to help the antibodies and white blood cells remove the virus. The immune response also includes cytotoxic T cells (lymphocytes), which recognize and kill infected cells. |
| 10 |
Which antibiotic is best for dengue? |
There is no specific medicine to treat dengue infection. If you think you may have dengue fever, you should use pain relievers withacetaminophen and avoid medicines with aspirin, which could worsen bleeding. You should also rest, drink plenty of fluids, and see your doctor. |
| 11 |
How to recover fast from dengue? |
Turmeric with milk is best remedy for faster recovery. Citrus fruits play an important role for dengue patients and it help in recovery. So, rich mix of antioxidants and vitamin C like orange, strawberries, lemon, papaya etc should be included in a diet twice a day," says Dr Sharma. |
| 12 |
Is a CBC test for dengue? |
Complete Blood Count (CBC): The complete blood count test is employed to assess various components of the blood. One crucial aspect is the platelet count, which tends to decrease during the later stages of dengue fever. Monitoring platelet levels is essential as low platelet count can lead to bleeding complications. |
| 13 |
How many days do platelets fall in dengue? |
Platelet counts usually drop significantly by day 4 of illness. In adults without dengue shock, platelet counts drop slightly to moderate from day 3 to day 7 of illness and return to normal by day 8 or 9. |
| 14 |
What is the recovery stage of dengue? |
The recovery phase is the final stage of dengue fever. Individuals who have passed the febrile phase without entering the critical phase, or those who have recovered from the critical second phase for 1-2 days, will reach the recovery phase. |
| 15 |
Can I test dengue at home? |
These tests look for the NS1 protein from the dengue virus in the blood. They usually use special antibodies with labels to find this protein. Orange Health Labs offers the convenience of dengue fever NS1 Antigen Rapid Test at home anywhere in Bangalore. |
