The genotyping protocol, quality control and quality assessment included use of the GRR program to validate familial relations [ 32], the program Loki to validate Mendelian consistency [ 33], SNP call rate > 98% and sample call rate > 97.5%.
All semen analysis protocols included quality control charts and competency review.
Analyses were conducted by the Reproductive Endocrine Research Laboratory at the University of Southern California, a laboratory with well-established protocols and quality control procedures.
Analyses were conducted by the Reproductive Endocrine Research Laboratory at the University of Southern California (FZS), a laboratory with well-established protocols and quality control procedures.
Detailed descriptions of instruments, survey protocols and quality control measures are described in a companion article in this volume (9).
The use of this highly sensitive technique increases the importance of robust protocols and quality control to prevent and if this occurs detect laboratory cross-contamination.
Protocols and quality control systems have been developed over the past years that are adequate to ensure excellent performance in settings with a low burden of TB.
Every component of the exon array methodology, from reagents and protocols to quality control and analysis software is different for the exon arrays compared to the previous 3' arrays.
MESA study sites use the same standardized protocols for quality control; hence, systematic differences in HRV measurement between sites or across subjects with different characteristics are unlikely.
