Detection of SFTSV virus infection by isolation of virus.
- Severe fever with thrombocytopenia syndrome
Whole blood, serum, CSF, fresh frozen tissues – minimum sample 0.5 mL.
Whole blood: collect in EDTA, heparin or citrate tubes, can submit as aliquots in sterile 1.5-2.0 mL screw cap tubes.
Serum: collect in serum (red top) or serum separator tubes (SST), centrifugation of serum tubes is not needed and should be avoided.
CSF: Collect in sterile 1.5-2.0 mL screw cap tubes.
Tissues: Fresh frozen tissues should be placed in plastic containers.
Store samples in refrigerator or frozen until being shipped for testing. Avoid freezing whole blood samples. Tissues should be shipped frozen. Ship frozen specimens on dry ice and refrigerated specimens on wet ice.
Shipping of specimens shall be done by a TDG certified individual in accordance with TDG regulations.
