Clinical relevance of PCR/ESI-MS detections in culture-negative samples
| Clinical relevance of detections | No. (%) of samples with results: |
|
|---|---|---|
| PCR-ESI-MS positive, culture negative (n = 33)a | PCR-ESI-MS multipositive, culture single-positive (n = 15) | |
| True bacteremia and/or candidemia with correct pathogen identification | 10 (30.3) | 3 (20.0) |
| True bacteremia and/or candidemia | 21 (63.6) | 7 (46.7) |
| Possible bacteremia and/or candidemia | 0 (0.0) | 3 (20.0) |
| False positive most likely due to skin contamination | 2 (6.1) | 2 (13.3) |
