Abstract
Screening for a deficiency of glucose-6-phosphate dehydrogenase (G6PD) in red blood cells is vital for determining the potentially life-threatening presence of congenital, hereditary or induced hemolytic anemias. In this study, a "sample-to-readout" paper-based point-of-care (POC) colorimetric biosensor was developed for direct detection of G6PD in whole blood by simple visual comparison to a color card. The G6PD paper sensor was highly stable with no observable loss in performance after room temperature storage for at least 6 weeks, and worked equally well at room temperature and 37 °C. The simple printed paper format and the stability of the colorimetric reagents facilitates scalable manufacturing. The ability to utilize well established sample collection and preparation protocols along with a colorimetric visual readout should facilitate future transfer of this proof-of-concept POC biosensor to remote or resource-poor locations.

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
