Abstract
The description and evaluation of a PCR-based assay for the detection and species identification of the eight known human herpesviruses are presented. Two primer pairs targeting well-conserved regions of the genome allowed the amplification of the DNAs of all known human herpesviruses at a high level of sensitivity (10 to 100 genome copies for most viruses). Identification of the virus species was achieved through restriction enzyme digestion with BamHI and BstUI, which yielded fragment sizes that were characteristic for each herpesvirus. Furthermore, it was demonstrated that this restriction enzyme panel allowed the discrimination between human herpesvirus 6 variant A and variant B. This assay format was validated over the course of 1 year in a clinical virology laboratory setting, where it was shown that it readily detected human herpesviruses, including occasional multiple infections, in a variety of clinical samples. The PCR assay was compared to isolation and electron microscopy for the detection of herpes simplex (HSV) and varicella-zoster virus (VZV) in clinical samples. All specimens positive by conventional methods were also positive by PCR. However, in a number of clinical specimens in which HSV or VZV could not be detected by conventional methods, PCR was able to demonstrate the presence of the virus.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
