как показатель RET-He помогает в диагностике безанемического жд: если он менее 31, то и ферритин менее 15, сравнение 2 групп показывает, что у увсех пациентов хоть анемии и не было, но и гемоглобин и гематокрит статистически ниже в группе жд (ферритин менее 15)
Control group G1: normal ferritin (≥ 15 ng/mL)
LID group G2: low ferritin (< 15 ng/mL).
Results: We selected 108 participants (G1: 88 (81.5%), G2: 20 (18.5%)), mean age = 36 years, F:M = 9:1. We noted, in G2, significantly lower rates for hemoglobin Hb (p < 0.001), hematocrit (p < 0.001), mean corpuscular hemoglobin MCH (p = 0.026), reticulocyte count (p = 0.039) and RET-He (p < 0.001) and significantly higher rate for RDW/CV (p = 0.009). RET-He averages were 29.1 pg in G2 and 31.1pg in G1. In multivariate analysis, only RET-He showed a significant difference between the two groups. Area under the curve was 0.872, the cutoff = 30.9 (sensitivity 100%, specificity 61%, PPV 37%, NPV 100%).
