Abstract
The flow cytometric test measures the fluorescence intensity of intact red cells labelled with the dye eosin-5-maleimide, which reacts covalently with Lys-430 on the first extracellular loop of band 3 protein. In this study, red cells from patients with hereditary spherocytosis (HS), congenital dyserythropoietic anaemia type II, South-east Asian ovalocytosis and cryohydrocytosis have produced a greater degree of reduction of mean channel fluorescence readings than those for other patient groups and normal controls. The predictive value of this test for membrane abnormality was compared with the results obtained from the sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) method, which is currently the reference laboratory test for the identification of membrane protein deficiencies in hereditary spherocytosis and for the detection of spectrin variants in hereditary elliptocytosis. The dye method is a reliable, speedy diagnostic test (2 h from sample collection to result) for HS with a sensitivity of 92.7% and a specificity of 99.1%. Thus, it will serve well as a first-line screening test for the diagnosis of hereditary spherocytosis in routine haematology.

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
