Fluorogenic Hand‐Held Immunoassay for the Identification of Ricin: Rapid Analyte Measurement Platform
Bibliographic record
Abstract
Rapid analyte measurement platform (RAMPtrade mark) fluorogenic hand-held immunoassays (HHAs) were evaluated for inclusivity/sensitivity, exclusivity/specificity, sample matrix effects, ruggedness/stability, and reproducibility in detection of ricin (RCA(60)), a potential biological threat agent. The limit of detection of HHAs for RCA(60) was 14 ng/mL or approximately 140 pg/test. HHAs were inclusive in detection of ricin RCA(60), RCA(120), ricin A chain, and ricin B chain and exclusive in discrimination of RCA(60) from other toxins. None of the sample matrices tested affected assay performance. RAMPtrade mark ratios were tolerant of increases in sample volume, however, a decrease in sample volume of 25% resulted in significantly increased readings. RAMPtrade mark readings were highly reproducible lot-to-lot, cartridge-to-cartridge, day-to-day, and reader-to-reader.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
