[Selection criteria for the establishment of reference values in tropical zones. Application to specific proteins: C-reactive protein, haptoglobin, transferrin in gabonese children].
About 220 children (110 boys and 110 girls) aged 18 months to 10 years, 65.9% have been selected from anamnesis, clinical, and biological criteria to produce reference values on specific proteins dependent inflammatory, anemia and hemolysis (C-reactive protein = CRP; Transferrin = TRF and Haptoglobin: HPT). Specimens have been analysed by Nephelometric immuno-chemical method. For the two groups, A1 [18 months-5 years] and A2 [5-10 years], the reference values of the whole study population are reported: CRP (A1 3.35 +/- 3 mg/l: A2 2.40 +/- 2.30 g/l, with a significant difference at Student Fisher "t" test p < 0.03); TRF (A1 4.05 +/- 1.5 g/l; A2 4.50 +/- 1.4 g/l; NS, p > 0.05) HPT (A1 2.55 +/- 2.0 g/l: A2 1.20 +/- 1.10 g/l; S(r) p < 10(-5)). Furthermore, for TRF, HPT we must consider the sex in the results meaning because of significant difference into boys and girls.
