Co vše lze zjistit ze slin?


Jako hudba budoucnosti vypadají nejnovější výsledky výzkumu slin. Ty totiž naznačují, že místo rozboru krve nám bude prováděn rozbor slin a výsledky budou k dispozici na PC? Nevěříte?

Již několik let se rozbor slin ukazuje jako velice slibný zdroj informací o celkovém zdraví organizmu. Rozbor slin je totiž výhodný z mnoha důvodů. Pro odběr vzorku není třeba žádných vpichů jehlou, je tedy bezbolestný. Odběr nevyžaduje odbornou zručnost a může být proveden v klidu domova.

Sliny jsou v centru zájmu nového diagnostického trendu zvaného salivaomika (v angl. salivaomics), neboli nauka o slinách. V dubnu tohoto roku odstartovala Americká společnost pro dentální výzkum nový projekt nazvaný „Vědecká základna pro salivaomiku“ (Salivaomics Knowledge Base – SKB), který poskytuje informace rozboru slin dobrovolníků. V databázi je v současnosti 1166 různých proteinů a biomarkerů, podle kterých se dají rozpoznat nejrůznější patologické procesy v našem organizmu. Databáze se neustále rozšiřuje o nové biomarkery. Možná již brzy tedy budeme své zdraví kontrolovat podle rozboru slin na svém PC prostřednictvím internetu.
