The blood film is one of the world's most widely and frequently used tests and has undergone remarkably few changes since its introduction in the late 1800s. This article gives direction and some standardization in the preparation of blood films used

Background: Nucleated red blood cells (NRBC) in blood specimens compromise the automated white blood cell (WBC) count on most hematology analyzers. This makes it necessary to correct the WBC count by subtracting separately counted NRBC by manual micr

In this study we examined the effects of in vitro oxygenation and deoxygenation on the spun micro-haematocrit (packed cell volume or PCV) and the electronically measured mean cell volume (MCV) and haematocrit (Hct) of red blood cells. Because PCV and

Reticulocyte analysis by flow cytometry offers precision and sensitivity greater than those of conventional morphologic methods and permits derivation of a reticulocyte maturity index. However, interlaboratory variability has not yet been reported. T

A multinational interlaboratory task force explored the important variables of platelet reference counting and developed a candidate flow cytometric reference method based on the RBC/platelet ratio. A multicenter comparison was performed to determine

We developed a flow cytometric method for the enumeration and classification of nonmalignant immature granulocytes (IG). In this study, IG are defined as most immature (IG stage 1: promyelocytes and myelocytes) and as more mature (IG stage 2: metamye

A statistical protocol for evaluating the need for duplicate coagulation testing was developed. It requires at least 32 sets of duplicate prothrombin times or partial thromboplastin times over the expected range of results. In addition to the statist
