title: Assessment of a new immunocytochemical technique in HbF-cell counting by a novel objective evaluation method.
abstract: A recently developed immunocytochemical technique in HbF-cell counting was assessed by an objective evaluation method. The basic principle of this method is the preparation of aliquots with predetermined HbF-cell (target) values. These aliquots serve as control samples to standardize the HbF-cell measurements by the new immunocytochemical technique, which uses the StreptABComplex/AP staining procedure (SAP) and visualization under white light. Immunofluorescence optical counts (IF) were performed in parallel with the new technique. A trend of inaccuracy was observed in low target values for both methods. As the level of target values increased, deviations became insignificant (relative accuracy < 8%) with SAP having slightly better results. Linear regression data of the estimated %HbF-cell rates by the two methods versus the target values were very satisfactory for both methods with SAP being slightly better. SAP seems to provide an accurate and reliable alternative for HbF-cell estimation comparable with the classical IF optical count.
