Detection of<i>Aspergillus</i>in lung and other tissue samples using the MycAssay Aspergillus real-time PCR kit
Bibliographic record
Abstract
The MycAssay™ Aspergillus real-time PCR kit was tested on tissues from patients with invasive fungal infections. Tissue samples from nine organ transplant recipients and 33 patients with haematological malignancy were from lung (n = 30), skin (n = 4), and others. Samples were preprocessed with proteinase K and lyticase, followed by DNA extraction and real-time PCR. For all samples, the sensitivity of the MycAssay Aspergillus test was 82% and specificity 79% relative to microscopy and 90% and 64%, respectively, compared with Aspergillus culture. The positive predictive value and negative predictive values compared with culture were 69% and 88% and were 88% and 69% compared with microscopy, respectively. The MycAssay Aspergillus test detected tissue invasive infections with Aspergillus fumigatus , Aspergillus flavus , and Aspergillus terreus.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
