Quality control (QC) of semen analysis is essential for the detection and correction of systematic errors and high variability. Regular QC assessment by the laboratory supervisor is required for laboratory accreditation and to maintain accuracy, precision and competence in the andrology laboratory. 

For manual counting, the QC-Beads can be used to evaluate technician techniques, counting protocols and counting chambers. For automated counting, the QC-Beads can be used to evaluate the performance of the optical system and the resulting computer image processing of an automated semen analyzer.

The researcher should perform a quality control check each day prior to counting sperm samples.

QC Beads

The Bioscreen QC beads are a better item than the Hamilton-Thorne Accu-Beads. I highly recommend them for daily QC as the numbers are consistent, unlike the other.
