Chikungunya Virus, PCR, Molecular Detection, Spinal Fluid
Use
The test provides qualitative detection of the chikungunya virus RNA in cerebrospinal fluid collected during the acute phase of infection, ideally less than 7 days from symptom onset. It is intended for patients with a clinical history and symptoms consistent with chikungunya virus infection. It is not recommended for screening healthy patients.
Special Instructions
Not provided.
Limitations
Negative results do not preclude infection with chikungunya virus and should not be used as the sole basis for treatment or management decisions. False negatives may arise from degradation of the virus RNA due to incorrect storage or shipment conditions, or if collected after the typical detection period of seven days post-symptom onset. Specimens must not be heat inactivated, and all results must be interpreted in conjunction with clinical history and symptoms by a trained professional.
