Table 2

Detailed results from the Russian patient samples in which PERV DNA was detected. QNS, quantity not sufficient; +, positive; −, negative; NT, not tested. Results were classed as uninterpretable when there was insufficient DNA to complete the testing algorithm.

  • * Tests for porcine mitochondrial DNA or centromeric sequence were only performed in samples testing positive for PERV DNA.

  • Results are followed in parentheses by individual results per 500,000 cells; results may come from different aliquots.

  • Insufficient sample to complete testing algorithm, PERV PCR performed twice (copy number <10, <10); remaining DNA tested for centromeric sequences.
