This test looks for the virus that causes Western equine encephalitis, a disease that's spread through bites from infected mosquitoes. Infants and young children who are infected are more likely to develop encephalitis, or inflammation of the brain. Adults are less likely to develop this complication. Horses can also become infected.
This test uses a sample of cerebrospinal fluid (CSF), which is the fluid that surrounds the brain and spinal cord.
You may need this test to find out if you are infected with the virus that causes Western equine encephalitis. Symptoms can develop rapidly and may include:
Nausea and vomiting
In babies, symptoms of Western equine encephalitis include fussiness, vomiting, fever, failure to eat, and seizures.
You may also have a blood test to check for the virus.
Many things may affect your lab test results. These include the method each lab uses to do the test. Even if your test results are different from the normal value, you may not have a problem. To learn what the results mean for you, talk with your health care provider.
This test typically measures levels of immunoglobulin M (IgM), a type of antibody that your immune system makes against the virus. If your CSF sample contains IgM antibodies, it's likely you have the disease.
This test requires a sample of cerebrospinal fluid, which is taken through a lumbar puncture in your lower back. During this procedure, you either sit up and lean forward or lie down on your side. A health care provider inserts a needle into your spine and draws out a sample of fluid through the needle.
Side effects of a lumbar puncture include:
Discomfort while the needle is inserted
Brain herniation, which is rare but life-threatening
Tell your doctor if you're taking medication or have any other medical conditions.
Health care providers sometimes use local anesthesia, especially in children, to numb the spot where the needle will be inserted. Children may get upset about the procedure, so a health care provider should thoroughly explain to kids what they can expect.
Health care providers sometimes use a CT scan to create images of the brain before a lumbar puncture. This is to check for high pressure within the skull that could lead to brain herniation from the procedure.
Be sure your doctor knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don't need a prescription and any illicit drugs you may use.
