“…Our previous study determined the performance of the i-CHROMA™ using the RIQAS and UKNEQAS quality control schemes with other PSA methods (Abbott 4000/e411, Beckman DXI standardised to WHO IRP96/670) exhibited a bias in RIQAS that was on the order of −2.99 to +6.8 ng/mL, with an average of +0.88 ng/mL. The UKNQEAS, on the other hand, displayed bias between +0.53 and +2.58 ng/mL, with an average of +1.46 ng/ mL [12]. Over 50% of the RIQAS and UKNEQAS approaches revealed a positive bias greater than 1.0 ng/ mL for all the methods used.…”

“…The performance of the Boditech iCHROMA with EQA materials from organizations such as the United Kingdom National External Quality Assessment Service (UKNEQAS) and Randox International Quality Assessment Scheme (RIQAS) has been well described with analytes such as human chorionic gonadotrophin (HCG) [7], follicle stimulating hormone (FSH) [7], leutinising hormone (LH) [7], Vitamin D [8], Prostate Specific Antigen (PSA) [9], testosterone [10], ferritin [11]. The detection of SARS-CoV-2 infection is important in the understanding of this infection and the importance of the EQA in harmonizing the various methods of detecting the antibodies is appropriate.…”

“…The Abbott AxSYM PSA assay was calibrated using the WHO standard 90/670 as a reference. [13] Linear regression and coefficient of correlation between the two tests yielded the regression equation y = 1.0283x -0.0973 and r = 0.992, respectively. The intra-assay precision was calculated by one evaluator, who tested three different concentrations of control material ten ©Annals of Health Research.…”
