Results can come negative if the specimen was collected after 7 days following the symptom onset.
Dengue ns1 elisa normal range. Presence of detectable dengue NS1 antigen. Dengue IgG IgM serology assays should be performed on follow up samples after 5-7 days of onset of fever to confirm dengue infection. Recommended to do NS1 Antigen by ELISA in the first 5 days of fever.
After 7-10 days of continuous fever the. The dengue test for NS1 antigen is a test for early diagnosis of dengue. This test looks for the presence of the dengue NS1 antigen which is a protein and toxin produced by the dengue virus.
It is detected in the lab by a method called ELISA enzyme-linked immunosorbent assay. This protein causes our body to produce an immune response by making antibodies to fight this viral infection. The NS1 antigen is present in the blood of an infected person as soon as the dengue.
Levels of 1-4 dengue causing antigens are captured on the test which after coming in contact with it display a dark red band in the test result window. Normal values for Dengue Antigen NS1 Test Price for Dengue Antigen NS1 Test Average price range of the test is between Rs250 to Rs4300 depending on the factors of city quality and availablity.

Presence of detectable dengue NS1 antigen. Dengue IgG IgM serology assays should be performed on follow up samples after 5-7 days of onset of fever to confirm dengue infection. Recommended test is NS1 Antigen by ELISA in the first 5 days of fever.
After 7-10 days of fever the recommended test is Dengue fever antibodies IgG IgM by ELISA Comments Dengue viruses belong to the family. The presence of nonstructural protein 1 NS1 antigen overlaps with the dengue virus DV viremic phase for the first 4 to 5 days following infection and therefore the performance characteristics of the InBios DV NS1 enzyme-linked immunosorbent assay ELISAwere compared to the Focus Diagnostics DV real-time polymerase chain reaction RT-PCR which detects RNA from all 4 DV serotypes. A similar figure of merit to the one used in conventional dengue NS1 capture using an enzyme-linked immunosorbent assay ELISA was applied to our results.
In general the positive patient samples can be clearly differentiated from the negative ones and the results agree with those obtained using ELISA. The largest signal-to-noise ratio observed during the experiments was 356 and the best. Recommended test is NS1 Antigen by ELISA in the first 5 days of fever.

What is the normal range for a dengue NS1 test.
The NS1 antigen can usually be detected in blood within 1-2 days after the symptoms and up to a period of 7 days. The negative test results indicate that the antigen has not been detected whereas a positive result indicates the presence of dengue. Results can come negative if the specimen was collected after 7 days following the symptom onset.
The InBios DENV NS1 IgM and IgG ELISAs had an overall sensitivity of 836 40 and 582 and an overall specificity of 978 978 and 556 respectively. Simultaneous testing for NS1 and IgM-antibodies yielded a sensitivity and specificity of. Overall the sensitivity of the RDTs ranged from 719791 while the sensitivity of the ELISAs varied between 856959 using virus isolation as the reference method.
Hi My Dengue NS1 Antigen Elisa report came positive with Test value - 97 and cut off - 10 Does it mean I have acute Dengue or its the premilnary stage. Table 6 illustrates the overall diagnostic performances of our ELISA for DENV NS1 method and the Platelia Dengue NS1 Ag ELISA of the 146 clinical serum samples 66 serum samples were from patients with dengue viral infections and 80 serum samples were from patients with non-dengue viral infections.
