The introduction of a new analytical analyzer into routine clinical biochemistry laboratories requires verification in order to test the analyzer's analytical features as defined by the manufacturer. The objective of this study was to explore whether the new coagulation analyzer Behring Coagulation System Xpand (BCS XP) can be employed for routine testing at the Department of Medical Laboratory Diagnostics at the Sveti Duh General Hospital. Additionally, the aim of the study was to investigate whether the new analyzer could replace the analyzer of the same type that is currently in use. The verification of the analyzer comprised tests of precision, trueness, linearity and carryover. The material used for precision determination included commercial control samples in two concentration levels: normal and pathological plasma. The material used for trueness evaluation consisted of patient samples taken from the Sveti Duh General Hospital and the Sestre Milosrdnice Clinical Hospital in order to cover the entire measurement concentration range. The material used for linearity testing included a fresh human sample for a range of fibrinogen and D-dimer values as declared by the manufacturer. The evaluation of carryover was based on normal and pathological triplicate plasma samples. Samples with detected interferences were excluded from further analysis. The results of analytical verification showed that imprecision meets the criteria declared by the manufacturer for all coagulation parameters. Trueness testing, which comprised several methods: bias evaluation, the Passing-Bablok regression analysis and the Bland-Altman analysis, revealed mean differences in the new analyzer for the following parameters: PT and PT INR, as well as fibrinogen. On average, the new analyzer records higher values for PT and fibrinogen, and lower values for PT INR. The evaluation of the measurement range, namely linearity, was conducted for both fibrinogen and D-dimer, and depicted by a linear equation along with its correlation coefficients and bias calculation. The obtained values demonstrate linear dependence between the variables. The carryover analysis showed that there is no significant carryover in measured samples. Therefore, it is possible to argue that the new analyzer Behring Coagulation System Xpand (BCS XP) is ready for use in routine work. The mean differences in certain parameters in relation to the existing coagulation analyzer used at the Department are possible because the old analyzer has been in use as the referent method for a long time. For the above reasons, the results obtained from the new analyzer are not completely comparable with the results obtained from the old analyzer, which is why the simultaneous use of the two analyzers should be avoided. Otherwise, clinicians should be informed about the existing differences.
