Flow cytometric detection of platelet-bound antibody in three horses with immune-mediated thrombocytopenia
Bibliographic record
Abstract
Immune-mediated thrombocytopenia (IMT) is a sporadic cause of thrombocytopenia in horses for which it is difficult to establish a definitive diagnosis. In this report, we describe 3 horses with severe thrombocytopenia in which flow cytometric analysis of platelets for surface-bound IgG was used in an attempt to substantiate a provisional diagnosis of IMT. A distinct proportion (4.28%, 5.04%, and 7.95%) of platelets with surface-bound IgG was detected in the 3 thrombocytopenic horses, but not in 6 healthy horses (0.03% to 0.15%) or 6 horses with colic (0.00% to 1.21%). These results, in conjunction with elimination of other potential causes of the thrombocytopenia, established a diagnosis of IMT. The horses were treated with glucocorticoids alone or in combination with azathioprine, and the thrombocytopenia gradually resolved. Flow cytometric detection of platelet-bound IgG was readily performed and may be a useful adjunct for the diagnosis of IMT.

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.
