Accuratezza dell’immunonefelometria come metodo di screening per la determinazione della proteinuria di Bence Jones
Accuracy of immunonephelometry as a screening method for Bence Jones proteinuria
<p>The Bence Jones protein (BJP) is an important biomarker for the identification and management of patients with plasma cell dyscrasia. The recommended method for BJP detection is the immunofixation, which is a time consuming and expensive procedure. The aim of the study was to evaluate immunonephelometry (INA) as a screening method for the identification of urine samples negative for BJP and to compare it to a simplified immunofixation method (uIFE-3). First morning urine samples were collected from 1000 consecutive patients and analyzed by INA. Samples with free light chain concentrations &gt;10 mg/L and &gt;5 mg/L were considered positive. All samples were further analyzed by uIFE-3 using 3 antisera (anti-GAM, -&kappa; and -&lambda;). The INA results (at both cut-off levels) were compared with the uIFE-3, showing a poor accuracy due to the high number of false positives and false negatives. Consequently, INA resulted unable to accurately screen BJP.</p>
