Evaluation of nucleated red blood cell screening using Sysmex XE-2100 blood cell analyzer
Bibliographic record
Abstract
Objective To evaluate nucleated red blood cell screening using the Sysmex XE-2100 blood cell analyzer.To analyze positive expected value and negative expected value about the alarm of nucleated red blood cells.And to evaluate the sensitivity and specificity of Q-flag result in a certain range.Methods With manual microscopic examination as the gold standard to recheck 103 cases of Sysmex XE-2100 NRBC alarm(100≤Q-flag≤300) samples and 105 cases of no alarm(Q-flag 100) samples.Results When 100≤Q-flag≤200,the positive expected value was 48%.When 200 Q-flag≤300,the positive expected value was 81%.When Q-flag≥100,the positive expected value was 60%.When Q-flag 100,the negative expected value was 86%.Conclusions Sysmex XE-2100 blood cell analyzer NRBC alarm has high sensitivity and specificity,but there are some interfering factors.The positive expected value of the alarm is associated with the interval about Q-flag value.

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.
