Guidelines for May‐Grünwald–Giemsa staining in haematology and non‐gynaecological cytopathology: recommendations of the French Society of Clinical Cytology (<scp>SFCC</scp>) and of the French Association for Quality Assurance in Anatomic and Cytologic Pathology (<scp>AFAQAP</scp>)

Abstract

The present review addresses all pre-analytical issues concerning the use of Romanowsky's stains (including MGG) in haematology and non-gynaecological cytopathology. It aims at serving as actualised, best practice recommendations for the proper handling of air-dried cytological specimens. It, therefore, appears complementary to the staining criteria of the non-gynaecological diagnostic cytology handbook edited by the United Kingdom National External Quality Assessment Service (UK-NEQAS) in February 2015.
