Aspergillus PCR: One Step Closer to Standardization
Open accessAbstract
PCR has been used as an aid in the diagnosis of invasive aspergillosis for almost 2 decades. A lack of standardization has limited both its acceptance as a diagnostic tool and multicenter clinical evaluations, preventing its inclusion in disease-defining criteria. In 2006, the European Aspergillus PCR Initiative was formed. The aim of the initiative was to provide optimal standardized protocols for the widespread clinical evaluation of the Aspergillus PCR to determine its diagnostic role and allow inclusion in disease diagnosis criteria. Quality control panels were developed and circulated to centers for evaluation of the existing methodology before recommendations based on the initial results were proposed for further panels. The centers were anonymously classified as “compliant” or “noncompliant,” according to whether they had followed the proposed recommendations before the performance parameters were determined and meta-regression analysis was performed. Most PCR amplification systems provided similar detection thresholds, although positivity was a function of the fungal burden. When PCR amplification was combined with DNA extraction, 50% of the centers failed to achieve the same level of detection. Meta-regression analysis showed positive correlations between sensitivity and extraction protocols incorporating the proposed recommendations and the use of bead beating, white cell lysis buffer, and an internal control PCR. The use of elution volumes above 100 μl showed a negative correlation with sensitivity. The efficiency of the Aspergillus PCR is limited by the extraction procedure and not by PCR amplification. For PCR testing of whole blood, it is essential that large blood volumes (≥3 ml) be efficiently lysed before bead beating to disrupt the fungal cell and performance of an internal control PCR to exclude false negativity. DNA should be eluted in volumes of <100 μl.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
