Version de la méthode

Mentzer index arithmetic v1: raw Mentzer index = mean corpuscular volume (MCV, fL) / red blood cell count coefficient in 10^12/L or the numerically equivalent million/µL identity; 1 × 10^12/L = 1 million/µL, so the coefficient is unchanged between accepted RBC unit identities

Population

Original historical pediatric microcytosis source setting, after applicability is independently established, using mean corpuscular volume and red blood cell count from the same contemporaneous complete blood count and specimen context, with reported units and analyzer parameter identities verified.

Limites et exclusions

Any cutoff, threshold, result category, differential conclusion, diagnostic classification, diagnosis, claim of modern diagnostic validation, management recommendation, treatment recommendation, or other clinical decision. · Mismatched samples or specimens, different CBC collection times, non-contemporaneous measurements, or unverified specimen identity, analyzer parameter identity, reported unit, or laboratory result. · Use outside the original historical pediatric microcytosis source setting without independently established applicability, or extrapolation to another population. · RBC input expressed as cells/µL or any unit identity other than the explicit coefficient in 10^12/L or million/µL; inferred or silently reinterpreted units.
