₹800.00
Description
- Definition: The Dengue Antigen (NS1) Rapid test detects the presence of the NS1 protein, a non-structural protein secreted by dengue virus during the early stages of infection. It provides a quick indication of an active dengue infection.
- Purpose: This test is primarily used for the rapid diagnosis of dengue fever, particularly in patients presenting with symptoms such as high fever, severe headache, and joint or muscle pain. Early detection is crucial for effective management and monitoring of the disease.
- Clinical Relevance: The NS1 antigen can be detected in the blood during the first week of infection, making this test especially useful in the early diagnosis of dengue. A positive result helps differentiate dengue from other viral infections and guides clinical management.
- Interpretation: A positive NS1 antigen test indicates an active dengue infection, while a negative result may suggest either a non-dengue illness or an infection outside the detectable window. Clinical correlation with symptoms and other laboratory findings is essential for accurate diagnosis.
- Testing Method: The rapid test involves a fingerstick or venous blood sample that is applied to a test strip or cassette. Results are available within a short period, usually 15-30 minutes, allowing for prompt diagnosis and treatment decisions.
