WebDec 10, 2013 · This protocol sets a threshold for in vitro hemolysis at 2% [49]. According to the E2524-08 protocol, if the assay result for a test-nanomaterial falls below this level, the material is considered non-hemolytic; hemolysis values between 2 and 5% are interpreted as moderately hemolytic and those above 5% qualify the test-nanomaterial as hemolytic. WebThis study aimed to assess the influence of spurious hemolysis and reliability of corrective formulas. Materials and methods :Blood collected into lithium heparin vacuum tubes was divided in aliquots and subjected to mechanical injury by aspiration with an insulin syringe equipped with a thin needle (30 gauge).
