FL Medical\u2019s K2 and K3 EDTA tubes are a key reference point for blood collection and preservation in diagnostic settings. These devices are designed to prevent blood coagulation during the analysis process and contain EDTA (ethylenediaminetetraacetic acid), an anticoagulant that binds calcium ions, thereby preventing clot formation. The difference between the two types of tubes is in the form of EDTA salt used: K2 tubes contain dipotassium salt (K2-EDTA), while K3 tubes contain tripotassium salt (K3-EDTA). Both are used in a variety of diagnostic tests, including complete blood counts (CBC), white blood cell counts, and genetic analyses.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=\u00bb1″ _builder_version=\u00bb4.27.0″ _module_preset=\u00bbdefault\u00bb background_color=\u00bb#f5f5f5″ custom_padding=\u00bb1px||2px|||\u00bb global_colors_info=\u00bb{}\u00bb][et_pb_row column_structure=\u00bb1_2,1_2″ _builder_version=\u00bb4.27.0″ _module_preset=\u00bbdefault\u00bb scroll_fade_enable=\u00bbon\u00bb global_colors_info=\u00bb{}\u00bb][et_pb_column type=\u00bb1_2″ _builder_version=\u00bb4.27.0″ _module_preset=\u00bbdefault\u00bb global_colors_info=\u00bb{}\u00bb][et_pb_image src=\u00bbhttps:\/\/www.flmedical.com\/wp-content\/uploads\/2025\/05\/k2-k3-landing_05.png\u00bb title_text=\u00bbk2-k3-landing_05″ align=\u00bbcenter\u00bb _builder_version=\u00bb4.27.0″ _module_preset=\u00bbdefault\u00bb max_width_tablet=\u00bb\u00bb max_width_phone=\u00bb\u00bb max_width_last_edited=\u00bbon|phone\u00bb custom_margin=\u00bb||||false|false\u00bb custom_margin_tablet=\u00bb50px||||false|false\u00bb custom_margin_phone=\u00bb0px||60px||false|false\u00bb custom_margin_last_edited=\u00bbon|phone\u00bb border_radii=\u00bbon|11px|11px|11px|11px\u00bb border_radii_tablet=\u00bbon|11px|11px|11px|11px\u00bb border_radii_phone=\u00bbon|11px|11px|11px|11px\u00bb border_radii_last_edited=\u00bbon|desktop\u00bb locked=\u00bboff\u00bb global_colors_info=\u00bb{}\u00bb][\/et_pb_image][\/et_pb_column][et_pb_column type=\u00bb1_2″ _builder_version=\u00bb4.27.0″ _module_preset=\u00bbdefault\u00bb global_colors_info=\u00bb{}\u00bb][et_pb_heading title=\u00bbStability and Safety: The Advantages of K2 and K3 EDTA Tubes\u00bb _builder_version=\u00bb4.27.0″ _module_preset=\u00bbdefault\u00bb title_text_color=\u00bb#008375″ width=\u00bb84%\u00bb custom_margin_tablet=\u00bb\u00bb custom_margin_phone=\u00bb60px||||false|false\u00bb custom_margin_last_edited=\u00bbon|phone\u00bb global_colors_info=\u00bb{}\u00bb][\/et_pb_heading][et_pb_text _builder_version=\u00bb4.27.0″ _module_preset=\u00bbdefault\u00bb global_colors_info=\u00bb{}\u00bb]<\/p>\n K2 and K3 EDTA tubes offer numerous benefits in laboratory settings.
