Abstract
Background:Patch testing for suspected sensitivity to cosmetics and other personal care products is usually done by testing with nonirritating products “as is” and by panels of antigens likely to contain causative ingredients. Most allergic reactions are reportedly due to sensitivity to either fragrances or preservatives. Although most preservatives found in patients' products are available for patch testing, only a small number of fragrance ingredients are available, and fragrance components are seldom labeled. Most personal care products contain many other ingredients, and unless the patient reacts to the whole product and the ingredients are obtained from the manufacturer, most of these are seldom tested. Methods:Investigators reviewed patch-test records of patients who presented with eruptions compatible with the use of their personal care products and who were tested with available ingredients that were listed on the labels of products they were using. This allowed testing with many ingredients in products that are too irritant for “as is” testing. Some of the results included those of persons who were tested in other series, so these were separated. Results:Of patch tests with 52 cosmetic ingredients also tested in other series, 3.4% produced at least one + or greater reaction. Of those antigens tested only when present in products used by the patient, 55 of the 121 ingredients produced at least one + reaction, and about 3.6% of the test results were positive. Conclusions:Adding ingredients found in the patient's personal care products to patch tests done on those compatible with exposure increases the positive yield in patch testing, and the number of positive results is likely to increase as more ingredients are available for testing.

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.
