Abstract:
In medical laboratories, the verification of methods ensures precise measurements, complying with regulatory standards like the Moroccan Guide for Medical Laboratory Analysis (GBEA) and ISO 15189. After organ transplantation, blood levels of cyclosporine are often monitored closely, and its dosage adjusted accordingly to maintain therapeutic levels while minimizing the risk of toxicity. This study aims to verify the analytical performance of the cyclosporine assay on the Abbott Alinity ci® analyzer. Conducted at Mohammed VI university hospital’s biochemistry laboratory over 30 days, it involved two phases: evaluation of reproducibility and repeatability. Reproducibility was assessed by daily testing of the control samples at three concentration levels (low, medium, and high), and repeatability was measured by subjecting each serum sample to 30 individual assay runs. Cyclosporine determination used a dedicated reagent kit on the Abbott Alinity ci® analyzer’s immunology module, with data processing via the BYG middleware. The resulting coefficient of variation (CV) values were compared against standards set by the supplier. The investigation demonstrated a commendable repeatability across all concentration levels, with CV values of 3.59%, 3.23%, and 3.46% respectively. Intermediate fidelity examination yielded satisfactory results, with CV values of 3%, 4.83%, and 6.01% for low, medium, and high levels respectively. In conclusion, our study confirms the laboratory’s capability to provide accurate and precise cyclosporine assay results for clinical use, meeting the recommended criteria set by the suppliers.

Abstract:
Abstract Objectives Sigma metrics in an invaluable and inexpensive tool used in laboratories to monitor analytical quality of the assays. Alinity ci platform is a relatively recent analytical system launched by Abbott Diagnostics, and as such performance studies on it are few. We have calculated sigma metrics of 39 clinical chemistry and immunoassay analytes on two Alinity ci systems. Methods Sigma metrics were calculated using results of method validation studies. Coefficient of variation (CV) was calculated according to CLSI EP 15 guidelines. Bias was calculated using three different methods i.e., proficiency testing material, alternate method comparison with existent analyzers and linearity experiment. Total allowable error limits were kept similar to or less than the ones used in reference studies. Results All analytes except blood urea nitrogen (BUN) demonstrated greater than six sigma value across one or more levels and methods. No analyte amongst clinical chemistry and immunoassays was at below three sigma class. Amongst electrolytes, sodium was below three sigma class at two levels by proficiency testing method, although it was above four sigma class by other two methods. Sigma levels obtained were comparable to those reported in previously published studies. Conclusions Acceptable sigma metrics were achieved for all clinical chemistry, immunoassays and electrolytes on Alinity ci. Sigma metrics is an objective and well established cost effective tool to tailor internal quality control practices. This study determines sigma metrics for a wide range of high throughput assays. Long term assay performance needs to be monitored.

Abstract:
ASO (AntiStreptolysin O) is an antibody directed against streptolysin O which is an exotoxin secreted by&nbsp;<em>Streptococcus pyogenes</em>. The assay is mainly used for the diagnosis of post-streptococcal complications (AAR, nephropathy, etc.), False positives may be observed in cases of hyperlipemic serum, or liver disease. The objective of our work is to evaluate the analytical performance of the ASO assay on the Abbott Alinity ci&reg; at the Biochemistry laboratory of the Mohammed VI University Hospital in Oujda. The methodology of this work is based on the evaluation of reproducibility and repeatability, based on the technical accreditation guide (SH GTA 04) of the French Accreditation Committee (COFRAC). The results obtained for the different ASO dosage verification criteria show satisfactory repeatability for both levels (1: low / 2: medium), Intra-laboratory reproducibility was also satisfactory for both levels. By comparing these results with the CV used by the CLSI, we see that the results are consistent with and below the tolerated limits. This study shows that the Biochemistry laboratory of the Mohammed VI University Hospital in Oujda is able to provide accurate and precise results which regards with the requirements of learned societies for the determination of ASO.

Abstract:
ABSTRACTCritical evaluation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) serologic assays is needed to guide clinical decision-making and ensure that these assays provide optimal benefit to patients and the public. Here, three commercially available assays with widespread distribution capabilities are compared. A total of 667 specimens, 103 from patients with confirmed SARS-CoV-2 infections and 564 collected prior to the emergence of SARS-CoV-2, were analyzed in parallel using the Roche Elecsys SARS-CoV-2 total antibody and Abbott Alinity SARS-CoV-2 IgG assays; a subset of 55 samples from patients with confirmed SARS-CoV-2 infections was additionally evaluated using the Abbott Architect SARS-CoV-2 IgM assay. Qualitative agreement between the Abbott IgG and Roche total antibody assays was 98.7% (658/667), with Cohen’s kappa value of 0.919 (95% confidence interval [CI], 0.867 to 0.972). Qualitative agreements with the Abbott IgM assay were 92.7% (51/55, Abbott IgG) and 85.5% (47/55, Roche total antibody). Diagnostic specificities determined using pre-COVID-19 samples for the Abbott IgG and Roche total antibody assays were 99.65% (95% CI, 98.72 to 99.90%) and 100.00% (95% CI, 99.32 to 100.00%), respectively, spanning claims made by each manufacturer. Diagnostic sensitivities increased for all three assays with increasing time since the onset of symptoms. Among 51 patients with confirmed SARS-CoV-2 infections, 23 (45.1%), 24 (47.1%), and 22 (43.1%) were reactive by the Abbott IgG, Roche total antibody, and Abbott IgM assays, respectively, with sampling times 0 to 56 days post-positive PCR (median/mean, 2/6.2 days). Combining IgG and IgM screening identified 4/55 additional samples with detectable antibodies that would not have been observed using the assays independently. Notably, one immunocompromised patient with confirmed SARS-CoV-2 infection showed no detectable antibodies using any of the three assays 43 days after onset of symptoms.

Abstract:
The verification of analytical methods is a requirement outlined by the International Organization for Standardization (ISO). This process involves evaluating the performance of an analytical method according to a well-defined protocol and comparing it with pre-established analytical objectives. In our study, we conducted an evaluation of the analytical performance of the free triiodothyronine (FT3) assay using the Abbott kit on the Alinity ci® analyzer in the biochemistry laboratory of Mohammed VI University Hospital in Oujda. The methodology adhered to the recommendations of the French accreditation committee (COFRAC) technical guide SH GTA 04, focusing on the assessment of repeatability and reproducibility. The results demonstrated excellent precision across low, medium, and high FT3 concentrations, with coefficients of variation (CV) within acceptable limits. These findings confirm the reliability of the Alinity ci® system for FT3 measurement, supporting its use in clinical diagnostics. It is important to note that the accuracy and reliability of examination results depend not only on laboratory personnel, equipment, and environmental conditions but also on the methods utilized and their validation or verification.

Abstract:
Paracetamol är den aktiva substansen i ett flertal smärtstillande läkemedel. Paracetamol äräven ett vanligt ämne vid självmordsförsök, då en överdos kan leda till livshotandeleverskador. Laboratoriet Klinisk Kemi i Karlskrona hade för avsikt att införa ett nyttreagens för kvantitativ in vitro analys av p-paracetamol på instrumentet Alinity serie cifrån Abbott®. Detta på grund av att reagenset från Abbott® inte behövde kalibreras likaofta som tidigare reagens. Syftet med studien var därför att genomföra en metodverifieringav reagenset Abbotts® Acetaminophen på två Alinity serie ci instrument. För attgenomföra en metodverifiering behövdes reagensets repeterbarhet och riktighetkontrolleras, samt en metodjämförelse genomföras. Detta gjordes genom att analysera enhög och en låg kontroll 25 gånger på masterinstrumentet och 20 gånger påslavinstrumentet. Därefter analyserades samma kontroller 5 gånger över fem dagar påmasterinstrumentet, samt 35 patientprover på både referensmetoden och den nya metoden.Det resultat som erhölls var att samtliga inomserie- och mellanserieprecisioner hade envariationskoefficient inom de riktlinje som företaget angivit. Metodjämförelsen visade ettlinjärt förhållande mellan de båda reagensen med en korrelationskoefficient på 0,9999.Den slutsats som drogs var att det fanns en god repeterbarhet för både master- ochslavinstrument gällande samtliga kontrollnivåer för inomserieprecisionen. Vidare, förmellanserieprecisionen på masterinstrumentet gav även detta en god repeterbarhet för bådakontrollnivåerna. Metodjämförelsen gav ett linjärt samband mellan de två metoderna ochhade en låg bias mellan varandra. Metodverifieringen kunde därför godkännas och den nyametoden Abbotts® Acetaminophen (Abbott Diagnostics) kunde tas i bruk på Klinisk Kemii Karlskrona.
