Abstract
OBJECTIVE: To identify a simple, cost-effective, reliable fixation method for fine needle aspiration biopsy (FNAB) yielding a specimen suitable for mail transport. STUDY DESIGN: Smears prepared from 59 FNABs of surgical specimens were fixed by continuous fixation in 95% ethanol, spray fixation, air drying, ethanol fixation for either 5 minutes or 4 hours followed by spray fixation, or fixation in 95% ethanol for either 30 minutes or 4 hours followed by air drying. Fixation was graded as unsatisfactory, suboptimal, average, good or excellent. RESULTS: Of smears continuously fixed in ethanol, 96.6% were graded as excellent. Of smears fixed in ethanol followed by spray fixation, 93.2% were excellent irrespective of fixation time; 64.4% of spray-fixed smears were excellent and 27.1% good. Of air dried smears, 93.2% were unsatisfactory or suboptimal; 83.0% of smears fixed in ethanol for 30 minutes and 74.6% of smears fixed for 4 hours prior to air drying were unsatisfactory or suboptimal. CONCLUSION: Fixation of smears in 95% ethanol followed by spray fixation produces excellent results, comparable to those with continuous fixation in ethanol. Spray fixation is generally good but not consistently excellent. Air drying or fixation in ethanol followed by air drying yields unsatisfactory or suboptimal results in most cases.

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
