Detection of antibodies against Ebola virus by ELISA
<<Return to LaboratoryRequisition Forms
Reference Details
Detection of IgG and/or IgM antibodies to Ebola virus infection by Enzyme Linked Immunosorbent Assays.
- Ebola virus disease
- Filovirus disease
Serum or plasma - minimum sample 0.5 mL
Collect in serum (red top) or serum separator tubes (SST), centrifugation of serum tubes is not needed and should be avoided.
Store samples in refrigerator or frozen until being shipped for testing. Serum can be shipped refrigerated or frozen. Ship frozen specimens on dry ice and refrigerated specimens on wet ice.
Shipping of samples suspected of containing Risk Group 4 pathogens shall be done by a TDG certified individual in accordance with TDG regulations. If applicable, activate Emergency Response Assistance Plan (ERAP) 24 hours prior to shipping. To activate an ERAP, please click on the link below to access the transport flowchart for Risk Group 4 pathogens or call 204-999-7996 (available 24/7) for assistance.
Transport Flowchart for Risk Group 4 Pathogen(s)Fever (or other symptoms) and travel to filovirus endemic areas or contact to travellers from these areas.
Completed Special Pathogens requisition including sender name, address and telephone number. Patient information including name or identifier, date of birth, and all relevant patient history including clinical diagnosis, underlying diseases, exposure risk and travel history. Indicate type of specimen collected and all specimen information. Select all required tests. If possible, attach lab results that have already been done at local or provincial laboratories.
All patient history must be included; sample without adequate patient history to justify testing are subject to rejection. Contact Special Pathogens prior to submission of sample to ensure appropriate shipping documentation is generated.
ELISA is non-routine test for investigational purposes.
For diagnosis of Ebola virus infection to be confirmed, one or more of the following diagnostic markers must be positive: (i) presence of filovirus-specific IgM or rising titres of IgG, (ii) presence of Ebola virus RNA by PCR, (iii) isolation of virus.
