Hereditary Spherocytosis (HS) is a hemolytic anemia where red blood cell membranes are spherical unlike common red blood cells, which are flat and round. In individuals with HS the spleen does not recognize these amorphous cells and destroys—rather filters—them them, making the individual anemic (MedlinePlus, 2013). HS is an autosomal dominant, or recessive autosomal inherited blood disease (Huq, Pietroni, Rahman & Alam, 2010) HS happens in 1 in 2,000 of the Caucasian population in or from Northern Europe (MedlinePlus, 2013). The proteins involved in HS are ankyrin-1, ά-spectrin, β-spectrin, band 3, and protein 4.2. Hyperbilirubinemia is a common symptoms in neonates with HS. According to Christensen and Henry (2010) hyperbilirubinemia is sometimes miss as a diagnose for HS (Christensen & Henrym 2010).
