Abstract
Iron is an essential nutrient, yet iron balance is precarious for much of the world’s population. In North America, iron deficiency is common in distinct population groups, such as women of child-bearing age. 1 Transfusion therapy is a cornerstone of modern medical care. Canada’s need for fresh blood components, including red blood cells, is met by approximately 600,000 volunteer donors. Canadian Blood Services (CBS) collects, processes, tests, and distributes blood components to all provinces and territories, except Quebec. Each year, CBS collects approximately 950,000 units of whole blood of 500 mL each. A dedicated group of repeat donors provide close to 90% of donations, while 10% of donations come from first time donors. The average donation frequency in 2012 was slightly over 2 donations per donor yearly. Donor hemoglobin (Hb) screening is performed on a fingerstick capillary sample prior to each donation, with a minimum qualifying level of 125 g/L required for both male and female donors, and 8% of female donors and 0.5% of male donors are temporarily deferred for inadequate Hb level. Each whole blood donation results in the loss of 225 to 250 mg of iron. However, no routine Key points

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; both teacher heads agree on what is shown here.
