Limitations	This is a presumptive assay. If a sample is positive the sample will be submitted to CDC for additional evaluation. Negative results do not preclude infection with Marburg virus and should not be used as the sole basis for diagnosis, treatment, or other patient management decisions. If the patient’s symptoms have been present for <3 days, a second sample collected more than 72 hours after onset of symptoms is required to definitively rule out Marburg.
