Biological Sex
تعریف
A user characteristic stored in HealthKit used for normative calculations and reference range interpretation.
یہ کیوں اہم ہے
Many health reference ranges are sex-specific: - VO₂ max classifications - Body fat percentage norms - Hemoglobin levels - Heart rate patterns - Metabolic calculations
Without this information, health metrics cannot be properly contextualized against population norms.
