Abstract
Whole blood in a serum clot tube and EDTA-anticoagulated samples from an 8-year-old spayed female Chinese Shar Pei dog were submitted by an external clinic to the diagnostic laboratory at Atlantic Veterinary College for routine biochemical and hematologic analysis prior to entropion surgery. Laboratory abnormalities included mild hyperkalemia (6.3 mmol/L, reference interval 3.6-6.0 mmol/L), mild normocytic, hypochromic, nonregenerative anemia (HCT 0.31 L/L, reference interval 0.37-0.55 L/L; MCHC 290 g/L, reference interval 320-360 g/L), and increased red cell distribution width (RDW; 26.2%, reference interval 11-14%). A small subpopulation of macrocytic, slightly hypochromic erythrocytes was noted on Wright's-Giemsa-stained blood smears. Biochemical and hematologic data obtained from this patient over the previous 7.5 years indicated that serum (and in 1 case, heparinized plasma) potassium concentration was increased (range, 6.3-10.9 mmol/L) in 5 of 8 samples (HCT ranged from 0.31-0.43 L/L, Hgb 91-124 g/L, MCHC 280-312 g/L, and RDW 18.2-26.9%). Clinical signs suggestive of hyperkalemia were not observed at any time, suggesting pseudohyperkalemia as the cause of the increased potassium concentrations. An erythrocyte lysate prepared from a heparinized blood sample had a high potassium concentration (16.8 mmol/L) compared with that of a clinically healthy, non-Shiba control dog (6.7 mmol/L). An osmotic fragility test of the patient's erythrocytes showed 50% hemolysis at 0.57% NaCl, compared with 0.48% NaCl for the control dog, indicating increased fragility. On scanning electron microscopy, a small subpopulation of erythrocytes were large, flattened, and had a tendency to fold. These findings supported the provisional diagnosis of pseudohyperkalemia due to increased intracellular RBC potassium concentration. High-potassium erythrocytes have been reported in Akitas, Shibas, Jindos, other East Asian dog breeds, and occasionally, in mixed-breed dogs. Pseudohyperkalemia should also be considered when an otherwise unexplained elevation in serum or plasma potassium concentration is observed in Chinese Shar Pei dogs, and may be accompanied by increased RDW, low MCHC, and increased osmotic fragility with or without mild anemia.

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.
