Laboratory tests revealed: microcytic anemia (Hemoglobin 9,5 mg/dL; Mean Corpuscular Volume 68) elevation of platelets (689/mm3, normal value <450/mm3), erythrocyte sedimentation rate (ESR) (25mm / h, normal value <20 mm/h), and C-reactive protein (CRP) (4mg / dL , normal value <1mg/dL) and serum amyloid A (SAA) (80 mg/L, normal value <6.4mg/L). Here, CRP is linked to anemia.
