Why might cell counting results differ from those obtained using other instruments or methods?

2026-06-23

Answer:
Variability in cell counting results may arise from multiple sources, as there is no universally accepted gold standard for cell counting.

Differences may result from sample preparation, including dilution accuracy, mixing uniformity, and sampling variability. In addition, differences in detection principles and algorithms between instruments may contribute to variation in results.

The instrument is calibrated using standard reference beads to maintain accuracy, and deviations are typically controlled within an acceptable range (approximately ±10%).
