Laboratory findings indicative of CIHA include indicators associated with hemolytic anemia, such as decreased hemoglobin, reduced haptoglobin levels, elevated LDH, and hyperbilirubinemia, and immunological indicators suggestive of immune-mediated hemolysis like a positive DAT for C3 and/or IgG/IgM (Arndt, 2014). Here, C3 is linked to Hyperbilirubinemia.
