What is the Japanese Encephalitis Virus (JEV) PCR Test?
A molecular diagnostic test that detects Japanese Encephalitis Virus (JEV) RNA in blood or cerebrospinal fluid (CSF) using Polymerase Chain Reaction (PCR).
Japanese Encephalitis is a mosquito-borne viral infection that can cause severe brain inflammation (encephalitis).
🎯 Purpose of the Test
✅ Diagnoses Japanese Encephalitis (JE) in symptomatic patients.
✅ Identifies JEV infection early, even before antibodies develop.
✅ Helps differentiate JE from other viral or bacterial infections affecting the brain.
📊 Normal Ranges & Interpretation
🔹 Normal Result: No detectable JEV RNA (Negative result).
🔹 Abnormal Result: Detectable JEV RNA, indicating an active infection.
📝 Test Procedure
1️⃣ A sample (blood or cerebrospinal fluid) is collected.
2️⃣ The sample undergoes PCR amplification to detect JEV RNA.
3️⃣ Results are analyzed to confirm the presence of the virus.
⚠️ Who Should Get Tested?
🔹 Patients with symptoms of JE, such as:
Fever, headache, vomiting
Seizures, confusion, paralysis
Unconsciousness in severe cases
🔹 Travelers or residents in JEV-endemic regions (Southeast Asia, Western Pacific).
🔹 Individuals with mosquito exposure and unexplained neurological symptoms.
✅ Why is This Test Important?
✔️ Early detection can improve treatment outcomes.
✔️ Helps prevent serious complications like brain swelling, coma, or death.
✔️ Aids in public health monitoring and outbreak control.
