为了规范细胞血液学实践，讲法语的细胞血液学小组(GroupeFranophoned\'HématologieCellulaire，GFHC）专注于Perls\'染色。进行了全国调查,提出了骨髓中不溶性铁检测和定量的建议。此处提出的标准符合“强有力的专业协议”，并遵循世界卫生组织对血液恶性肿瘤分类的建议。
In order to standardize cellular hematology practices, the French-speaking Cellular Hematology Group (Groupe Francophone d\'Hématologie Cellulaire, GFHC) focused on Perls\' stain. A national survey was carried out, leading to the proposal of recommendations on insoluble iron detection and quantification in bone marrow. The criteria presented here met with a \"strong professional agreement\" and follow the suggestions of the World Health Organization\'s classification of hematological malignancies.
