It categorizes tubes by stopper color—including blue, red/gold, green/mint, lavender, pink, grey, and yellow—and maps each to its corresponding additive, the blood component used for testing, the additive's specific function, commonly performed laboratory tests, and essential procedural precautions. By outlining the standard sequence and specific requirements for each tube type, the guide serves as a critical resource for healthcare professionals to ensure accurate sample collection, maintain cell morphology, and prevent analytical errors during clinical diagnostics, such as coagulation studies, hematology analysis, and glucose monitoring.",{"@graph":63,"@context":119},[64,80,102],{"@type":65,"itemListElement":66},"BreadcrumbList",[67,71,74,77],{"item":68,"name":69,"@type":70,"position":9},"https://docshare.wps.com","Home","ListItem",{"item":72,"name":10,"@type":70,"position":73},"https://docshare.wps.com/template/",2,{"item":75,"name":51,"@type":70,"position":76},"https://docshare.wps.com/template/general/",3,{"item":78,"name":59,"@type":70,"position":79},"https://docshare.wps.com/template/tube-types-additives-and-their-function/571730/",4,{"url":78,"name":59,"@type":81,"image":82,"author":87,"headline":59,"publisher":90,"fileFormat":93,"inLanguage":57,"description":61,"dateModified":94,"datePublished":95,"encodingFormat":93,"isAccessibleForFree":96,"interactionStatistic":97},"DigitalDocument",{"url":83,"@type":84,"width":85,"height":86},"https://docshare.wps.com/thumbnails/tube-types-additives-and-their-function/571730.png","ImageObject",442,249,{"name":88,"@type":89},"Angel","Person",{"url":68,"name":91,"@type":92},"DocShare","Organization","application/pdf","2026-10-26","2026-10-13",true,{"@type":98,"interactionType":99,"userInteractionCount":101},"InteractionCounter",{"@type":100},"ViewAction",7,{"@type":103,"mainEntity":104},"FAQPage",[105,111,115],{"name":106,"@type":107,"acceptedAnswer":108},"What is the correct order of draw for a blue top tube?","Question",{"text":109,"@type":110},"The blue top tube containing sodium citrate is drawn first to perform coagulation studies.","Answer",{"name":112,"@type":107,"acceptedAnswer":113},"Why should you avoid drawing lithium levels in a green/mint top tube?",{"text":114,"@type":110},"Green/mint top tubes often contain lithium heparin, which can interfere with testing results; similarly, sodium levels should not be drawn in sodium heparin tubes.",{"name":116,"@type":107,"acceptedAnswer":117},"What is the primary function of the additive in a lavender top tube?",{"text":118,"@type":110},"The lavender top tube contains K2 EDTA, which inhibits clotting and preserves cell morphology for hematology testing.","https://schema.org",{"og:url":78,"og:type":121,"og:title":59,"og:site_name":91,"og:description":61},"article",{"robots":123,"canonical":78},"index,follow",{"doc_id":125,"site_id":56},571730,1792095975,{"code":4,"msg":5,"data":128},{"doc_id":125,"user_id":129,"nickname":88,"user_avatar":130,"doc_module":9,"category_id":50,"category_name":51,"doc_title":59,"doc_description":61,"doc_content":131,"file_id":132,"file_url":133,"file_type":134,"file_size":135,"view_count":101,"is_deleted":4,"is_public":9,"is_downloadable":9,"audit_status":9,"page_count":9,"language":136,"language_code":57,"site_id":56,"html_lang":57,"table_of_contents":137,"faqs":138,"seo_title":139,"seo_description":61,"update_tm":140,"read_time":4},687207412472,"https://ap-avatar.wpscdn.com/davatar_155a257f0dc6eb9ab79c44ca47cae57d","TUBE TYPES, ADDITIVES AND THEIR FUNCTION  \n\n| STOPPER COLOR |  |  |  |  | POSITION IN\u003Cbr>THE ORDER OF DRAW | ADDITIVE | BLOOD COMPONENT USED\u003Cbr>IN TESTING | FUNCTION OF ADDITIVE | COMMONLY\u003Cbr>PERFORMED\u003Cbr>TESTS | PRECAUTIONS |\n| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |\n|  |  |  |  |  |  |  |  |  |  |  |\n| \u003Cbr>BLUE |  |  |  |  | 1 | SODIUM CITRATE | PLASMA | BINDS CALCIUM | COAGULATION STUDIES (PTIN/APTT) | \u003Cbr>MUST BE FULL |\n| |  | |  |  | 2 | CLOT ACTIVATOR\u003Cbr>(SILICA) | SERUM | PROMOTES CLOTTING/ SEPARATES\u003Cbr>SERUM FROM CELLS | CHEMISTRY SEROLOGY IMMUNOLOGY (BMP/COMP) | FACILITATES COMPLETE NOT FASTER CLOTTING.
