ABSTRACT
Special Considerations Meconium has a marginal impact on LB counts, increasing the count by 5000/mL. Bloody fluid can initially slightly increase the count because the platelets are counted as LB. Afterward, the procoagulant activity of AF produces an entrapment of both, platelets and LB, causing a decrease in LB counts. Because of variations in hematology analyzers, ideally laboratories should develop their own reference standards (16).
