Un v\u00e9ritable d\u00e9fi pour la v\u00e9rification de tests salivaires de d\u00e9pistage de stup\u00e9fiants effectu\u00e9e en laboratoire.<\/strong><\/p>\n<p>La salive est l\u2019un des liquides corporels les plus complexes ; elle joue un r\u00f4le majeur dans de nombreux processus de l\u2019organisme. Ses fonctions comprennent la lubrification des muqueuses buccales, la pr\u00e9paration \u00e0 la digestion ou encore l\u2019humidification des aliments. Pour r\u00e9pondre \u00e0 ces besoins, sa composition est diverse et variable. Outre de l\u2019eau, elle contient de nombreux autres composants, dont 400 types de prot\u00e9ines \u00e0 elle seule. La salive pr\u00e9sente une composition diff\u00e9rente chez chaque individu en fonction de sa condition physique.<\/p>\n<p>L\u2019acquisition de quantit\u00e9s de salive naturelle n\u00e9cessaires aux tests en laboratoire n\u2019est pas une t\u00e2che ais\u00e9e. En parall\u00e8le, les demandes en salive standard reproductible se sont multipli\u00e9es. C\u2019est ainsi qu\u2019est apparu le besoin en salive artificielle.<\/p>\n<h3>Les inconv\u00e9nients de la salive artificielle<\/h3>\n<p>\u00c0 ce jour, personne n\u2019est parvenu \u00e0 reproduire la salive de mani\u00e8re r\u00e9aliste. Les alternatives artificielles constituent toujours une repr\u00e9sentation nettement simplifi\u00e9e de la salive naturelle \u00e0 laquelle elle ne peut jamais \u00eatre enti\u00e8rement compar\u00e9e.<\/p>\n<p>Il existe de nombreuses recettes de salive diff\u00e9rentes en concurrence les unes avec les autres. Une partie de ces produits est enrichie en additifs conformes \u00e0 des exigences sp\u00e9cifiques, notamment pour les tests de corrosion sur proth\u00e8ses dentaires. De plus, afin de stabiliser la salive artificielle, certaines substances non pr\u00e9sentes dans la salive naturelle sont souvent utilis\u00e9es. Celles-ci peuvent avoir un effet sur les propri\u00e9t\u00e9s physiques de l\u2019alternative synth\u00e9tique.<\/p>\n<p>Les mucines, des glycoprot\u00e9ines extr\u00eamement complexes, sont des composants essentiels de la salive naturelle et synth\u00e9tique lui conf\u00e9rant sa viscosit\u00e9. Jusqu\u2019\u00e0 aujourd\u2019hui, personne n\u2019est parvenu \u00e0 isoler une quantit\u00e9 suffisante et stable de ces mucines \u00e0 partir de la salive humaine. C\u2019est pourquoi, pour la production de salive artificielle, on recourt g\u00e9n\u00e9ralement aux mucines de diff\u00e9rents mammif\u00e8res, souvent extraites du pancr\u00e9as. Lorsque des tests de d\u00e9pistage des stup\u00e9fiants sont r\u00e9alis\u00e9s en laboratoire sur de la salive artificielle, le cocktail des diff\u00e9rents additifs entra\u00eene g\u00e9n\u00e9ralement des r\u00e9sultats fauss\u00e9s.<\/p>\n<h3>La salive r\u00e9elle est incontournable<\/h3>\n<p>Dans l\u2019ensemble, les r\u00e9sultats obtenus avec les alternatives salivaires sont tr\u00e8s diff\u00e9rents et ils ne sont quasiment pas comparables entre eux. En raison de leurs compositions diff\u00e9rentes, les r\u00e9sultats de test obtenus avec la salive naturelle ne sont pas non plus comparables \u00e0 ceux de tests r\u00e9alis\u00e9s sur la base de salive synth\u00e9tique. Actuellement, il n\u2019existe aucun standard g\u00e9n\u00e9ralement reconnu.<\/p>\n<p>En raison de toutes ces diff\u00e9rences et incertitudes, les \u00e9tudes scientifiques men\u00e9es se fondent presque exclusivement sur la salive naturelle. Et tout porte \u00e0 croire que les conditions des tests ne changeront pas \u00e0 l\u2019avenir, par souci de r\u00e9alisme.<\/p>\n<\/div><\/section>\n<div  class='hr av-g82jd-83b065b6d70837985c8485fa31cc1e56 hr-default  avia-builder-el-3  el_after_av_textblock  el_before_av_textblock '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<section  class='av_textblock_section av-mgq70hbs-9dc47e015acf20dba1cff76c9d11c83e '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><h2>Crit\u00e8re de qualit\u00e9 : test\u00e9 avec de la salive r\u00e9elle<\/h2>\n<p>Malgr\u00e9 les d\u00e9penses nettement plus \u00e9lev\u00e9es associ\u00e9es \u00e0 l\u2019utilisation de salive r\u00e9elle pour les tests en laboratoire, les tests rapides de d\u00e9pistage de Securetec Detektions-Systeme AG sont uniquement d\u00e9velopp\u00e9s et test\u00e9s avec cette m\u00e9thode.
