Molecular Detection of antibodies to KFD virus by PCR amplification of KFD virus specific genome
- Kyasanur forest disease (monkey disease)
Whole blood, serum, fresh frozen tissues - minimum sample 0.5 mL. Formalin-fixed and/or paraffin-embedded tissues.
Serum: collect in serum (red top) or serum separator tubes (SST), centrifugation of serum tubes is not needed and should be avoided.
Whole blood: collect in EDTA, heparin or citrate tubes, can submit as aliquots in sterile 1.5-2.0 mL screw cap tubes.
Tissues: Fresh frozen tissues should be placed in plastic containers. Tissues that are formalin-fixed should also be sent in plastic containers and clearly identified as being in formalin. Paraffin-embedded tissues can be sent as entire blocks or four to six 10 uM sections in a plastic tube or vial.
Store samples in refrigerator or frozen until being shipped for testing. Serum can be shipped refrigerated or frozen. Avoid freezing whole blood samples. Tissues should be shipped frozen. Ship frozen specimens on dry ice and refrigerated specimens on wet ice. Formalin-fixed samples can be sent at room temperature.
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.

Symptomatic and travel to KFD virus 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.
For diagnosis of KFD infection to be confirmed, one or more of the following diagnostic markers must be positive: (i) presence of KFD virus by PCR, and (ii) isolation of KFD virus.
