Evaluation of a New Automated Mono-Test for the Detection of <i>Aspergillus</i> Galactomannan: Comparison of <i>Aspergillus</i> Galactomannan Ag VirCLIA<sup>®</sup> Mono-Test with Platelia<sup>TM</sup> <i>Aspergillus</i> Ag ELISA Assay

The analytical performance of the new <i>Aspergillus</i> Galactomannan Ag VirCLIA<sup>®</sup> mono-test (Vircell S.L.) was compared to the Platelia™ <i>Aspergillus</i> Ag ELISA assay (Bio-Rad). Prospective serum and bronchoalveolar lavage (BAL) samples from patien...

description The analytical performance of the new <i>Aspergillus</i> Galactomannan Ag VirCLIA<sup>®</sup> mono-test (Vircell S.L.) was compared to the Platelia™ <i>Aspergillus</i> Ag ELISA assay (Bio-Rad). Prospective serum and bronchoalveolar lavage (BAL) samples from patients at risk of invasive aspergillosis (IA) were tested using both the <i>Aspergillus</i> Galactomannan Ag VirCLIA<sup>®</sup> mono-test and the Platelia™ <i>Aspergillus</i> Ag ELISA assay. Concordance, sensitivity, specificity, and positive and negative predictive values were calculated using the manufacturer-recommended cutoff levels. Receiver operating characteristic (ROC) analysis and the Youden index were performed to determine the optimal cutoff. A total of 187 serum samples and 73 BAL samples were analyzed with both assays. The concordance between the <i>Aspergillus</i> Galactomannan Ag VirCLIA<sup>®</sup> mono-test and the Platelia™ <i>Aspergillus</i> Ag ELISA assay was 87.8%, with a Cohen’s kappa of 0.75. The sensitivity and specificity of the <i>Aspergillus</i> Galactomannan Ag VirCLIA<sup>®</sup> mono-test were 78.6% and 96.2%, respectively, with positive and negative predictive values of 94.8% and 83.3%. The ROC curve for the <i>Aspergillus</i> Galactomannan Ag VirCLIA<sup>®</sup> mono-test demonstrated an area under the curve (AUC) of 0.87, and the Youden index at the manufacturer’s established cutoff was 0.73. This new <i>Aspergillus</i> Galactomannan Ag VirCLIA<sup>®</sup> mono-test exhibited adequate analytical and clinical performance, showing good correlation with the Platelia™ <i>Aspergillus</i> Ag ELISA assay. The single-sample, semi-automated test is user-friendly, allowing small laboratories to perform the test on demand without the need for batch evaluations, providing a useful solution for timely diagnostic support for clinicians.
