ICSH--recommended methods for radioisotope red cell survival studies.

Clinical significance of optimal red cell mass and plasma volume estimation methods.

BACKGROUND The aim of this study was to present and compare the results of proposed methods for optimal red cell mass and plasma volume (RCM&PV) estimation, and their influence on the interpretation of obtained results. MATERIAL AND METHODS In 120/280 patients with polycythaemia rubra vera, subjected to RCM&PV determination with autologous erythrocytes in vitro labelled with 51Cr-sodium chrom...

The Clinical Significance of Schistocytes: A Prospective Evaluation of the International Council for Standardization in Hematology Schistocyte Guidelines

OBJECTIVE The presence of ≥1% schistocytes on a peripheral blood smear (PBS) is an important criterion for the diagnosis of thrombotic microangiopathy (TMA). The reporting of schistocytes has been standardized by the International Council for Standardization in Hematology (ICSH). Despite the availability of guidelines, however, the assessment of schistocytes remains subjective. More recently, t...

Recommendation for standardization of haematology reporting units used in the extended blood count.

INTRODUCTION It is desirable in the interest of patient safety that the reporting of laboratory results should be standardized where no valid reason for diversity exists. This study considers the reporting units used for the extended blood cell count and makes a new ICSH recommendation to encourage standardization worldwide. METHODS This work is based on a literature review that included the ...

ICSH recommendations for measurement of erythrocyte sedimentation rate. International Council for Standardization in Haematology (Expert Panel on Blood Rheology)

The Expert Panel on Blood Rheology of the International Council for Standardization in Haematology (ICSH) has prepared new recommendations for measurement of the erythrocyte sedimentation rate (ESR) under the following categories: 1. ICSH reference method-ICSH now recognises, as its reference method for the ESR, the sedimentation of EDTA-anticoagulated but undiluted blood in traditional Westerg...
