Laboratory findings at the University Hospital of Göttingen showed severe anemia (hemoglobin at 6 g/dL), thrombocytopenia (17.7 × 106 cells/μL), an increase in lactate dehydrogenase (LDH) activity (963 U/L, reference < 350 U/L), and negative haptoglobin (< 0.2 g/L, normal range 0.45 to 2.05 g/L). This evidence concerns the gene HP and anemia (phenotype).
