However, upon laboratory evaluation, marked elevation in erythrocyte sedimentation rate (ESR, 98 mm/hour), mild elevation of serum C-reactive protein (CRP, 13 mg/L), mild normocytic anemia (Hb, 113 g/L), elevated serum creatinine (80 μmol/L), mild proteinuria (0.38 g/day), microalbuminuria (urine albumin-to-creatinine ratio, 58 mg/g), elevated values of alpha-1 microglobulin (urine alpha-1-microglobulin-to-creatinine ratio, 3.24 mg/g), and normoglycemic glycosuria (1+) were observed. This evidence concerns the gene AMBP and anemia (phenotype).
