West Nile virus
Fever, headache, marked fatigue and muscle and joint pain may be signs of West Nile virus infection.
Analiza offers a rapid test for IgG and IgM antibodies to West Nile virus – an additional laboratory option when infection is suspected.
- One blood sample
- IgG and IgM antibodies
- Read after 15 minutes
What is West Nile virus?
West Nile virus infection is a viral infection most often transmitted to people through the bite of an infected mosquito.
The infection may be symptom-free, while some affected people develop symptoms similar to other viral infections – making them difficult to connect to West Nile virus.
Analiza offers a rapid test for IgG and IgM antibodies to West Nile virus – an additional laboratory option when infection is suspected.
The disease is strongly seasonal and occurs more frequently during periods of increased mosquito activity.
Which symptoms may suggest infection?
When symptoms develop, they may include:
fever
headache
marked fatigue and weakness
muscle and joint pain
digestive symptoms
skin rash
Tiredness and exhaustion may persist after other symptoms subside.
In rare cases, the infection can affect the central nervous system and cause more serious complications such as meningitis or encephalitis.
When should you consider testing?
If you have fever, headache, marked fatigue, muscle and joint pain or other symptoms resembling a viral infection, particularly during periods of increased mosquito activity, the test can provide additional laboratory assistance when West Nile virus infection is suspected.
You do not need to be aware of a mosquito bite for exposure to the virus to be possible.
A rapid test from one blood sample simultaneously checks for IgM and IgG antibodies to West Nile virus.
What do IgM and IgG antibodies reveal?
IgM – may indicate a more recent infection
IgM antibodies generally appear earlier during the body’s immune response. Their presence may indicate recent or current infection.
IgG – may indicate previous contact with the virus
IgG antibodies appear later and may remain after infection has resolved. Their presence may indicate previous exposure to the virus.
The result is always interpreted alongside symptoms, their timing and the clinical picture.
What does testing involve?
Have blood collected
The test requires one blood sample, from which serum is separated for analysis.
We check IgG and IgM antibodies
The rapid test checks for IgG and IgM antibodies to West Nile virus.
The test is read after 15 minutes
The test is read in the laboratory 15 minutes after starting the analysis.
You receive the result
The report shows whether IgG and/or IgM antibodies to West Nile virus were detected in the sample.
