Over the first two years of the contract, the EQAPOL Oversight Laboratories received training, developed standard operating procedures and quality management practices, implemented strict quality control procedures for equipment, reagents, and documentation, and received audits from the EQAPOL Central Quality Assurance Unit.
They employ well-trained personnel, they use modern equipment and have strict quality assurance procedures.
"Nobody was requesting anything," concedes Rice, so the team decided to pivot once again by switching the model to a more conventional marketplace, while still keeping the focus on buyer input via various customisation options for each product and ensuring strict quality control procedures are in place.
Although strict quality control procedures were implemented in all surveys, direct comparisons were not done.
The design of the whole project did not include very strict quality control procedures for data collection.
A standardized protocol and strict quality control procedures were implemented to achieve reliable ultrasonic measurements of cIMT.
Strict quality control procedures, including duplicate data entry of a proportion of randomly selected records, were carried out throughout the study period.
We implemented a standardized protocol and strict quality control procedures to achieve reliable ultrasonic measurements of the carotid artery IMT [ 22].
Strict quality control procedures are paramount to the accuracy of imputation, to ensure that genotyping errors are excluded prior to imputation, usually by manually checking the intensity cluster plots for all associated variants.
Following strict quality assessment procedures in both techniques, (RNA quality, cross-hybridisation of microarray probes, microarray spot intensity, qPCR primer design, and PCR efficiency) and data filtering after normalization (cut-offs for fold-changes and low microarray spot intensity) resulted in high correlation between qPCR and microarray data (Additional file 9) [ 60, 61].
