Assessment of novel POCT to evaluate liver function
Objectives
Point of care testing (POCT) offers the possibility of near bedside patient testing with a reduction of the turn-around time of analysis. The aim of our study was to determine the analytical performances and usability of a recently developed POCT device for the measurement of tests related to liver function. We evaluated the performance of a liver tests panel performed on the LINX EVO® POCT device.
Design and methods
The imprecision was determined with the Bio-Rad Liquichek Unassayed Chemistry Control. Method comparison was performed with a Cobas® 8000 analyzer. Samples from twenty healthy volunteers were used to verify the reference intervals. Furthermore, practicality was assessed by the healthcare staff handling the POCT device through a dedicated questionnaire.
Results
The imprecision observed was matching the criteria for the in-lab assay with only one exception, globulin, with an observed imprecision of 6.3 % and a criteria of 5.7 %. With the exception of total and direct bilirubin, the POCT method showed good agreement with the in-lab methods. The verification of reference intervals showed that more than 90 % of the healthy volunteer values were included into the reference interval claimed by the manufacturer except for glucose and globulin. The POCT practicality questionnaire was satisfying overall for users.
Conclusions
Our study showed very good analytical performances overall for the liver test panel performed on the LINX EVO® POCT instrument.
期刊介绍：
Practical Laboratory Medicine is a high-quality, peer-reviewed, international open-access journal publishing original research, new methods and critical evaluations, case reports and short papers in the fields of clinical chemistry and laboratory medicine. The objective of the journal is to provide practical information of immediate relevance to workers in clinical laboratories. The primary scope of the journal covers clinical chemistry, hematology, molecular biology and genetics relevant to laboratory medicine, microbiology, immunology, therapeutic drug monitoring and toxicology, laboratory management and informatics. We welcome papers which describe critical evaluations of biomarkers and their role in the diagnosis and treatment of clinically significant disease, validation of commercial and in-house IVD methods, method comparisons, interference reports, the development of new reagents and reference materials, reference range studies and regulatory compliance reports. Manuscripts describing the development of new methods applicable to laboratory medicine (including point-of-care testing) are particularly encouraged, even if preliminary or small scale.
