Summary of the results obtained in a blind study of detection of CWD prions in blood samples from white-tailed deer at various stages of CWD.
CWD status | Total number of animals | PMCA positive1 | % Correct diagnosis |
---|---|---|---|
Symptomatic (B + LN + ) | 5 | 5 | 100% |
Asymptomatic (B + LN + ) | 49 | 47 | 97% |
Asymptomatic (B- LN + ) | 34 | 18 | 53% |
Negative (B- LN-) | 10 | 0 | 100% |
1Samples were declared as positive in PMCA if at least one of the replicates gave a protease-resistant PrPSc signal in any of the PMCA rounds analyzed.
