Why This Test Matters

qPCR adds quantification to speed: monitoring fluorescence each cycle allows both rapid detection and measurement of pathogen load — critical for monitoring viral infections such as CMV and EBV in transplant patients.

Clinical Utilization

Qualitative detection where speed matters, and quantitative monitoring (viral load) where calibrated. Simultaneous analysis of hundreds of samples with a high degree of analytical precision.

Advantages

  • Real-time quantification with high analytical precision
  • Quantitative interpretation where calibrated
  • High throughput
  • High sensitivity and specificity

Limitations

  • Cq/Ct values are assay- and platform-specific and cannot be compared across assays without calibration
  • Quantitative results require validated standards
  • A low/negative Cq does not exclude infection
