To simplify the reading of acid eluted blood smears for fetal hemoglobin, positive and negative controls are placed side by side on a single slide. Red blood cells having high Hb F content are stained a bright pink in contrast to cells devoid of Hb F which appear as ghost cells with a faint pink outline. A method for preparing, fixing, and short-term storing of control slides with their subsequent room temperature acid elution and staining is given.
