Methodological assessment and bias estimation of two serum procalcitonin analysis systems / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the comparability and bias of the test results of two detection systems for serum procalcitonin (PCT) under the same laboratory condition.</p><p><b>METHODS</b>According to the profile NCCLS-EP9-A, the two systems were used to detect PCT to obtain the correlation coefficient and the liner equation for evaluation of the test result bias.</p><p><b>RESULTS AND CONCLUSION</b>The test results of PCT showed no significant difference between the two detection systems (P>005) with a kappa value greater than 0.75. The correlation coefficients of both systems were above 0.975, suggesting a consistency between them for clinical detection of PCT.</p>
