Cotinine Rapid Test Self-Test

Cotinine Rapid Test Self Test yog ib qho tshuaj tiv thaiv kab mob sai sai siv rau kev kuaj pom zoo ntawm cotinine hauv cov zis. Nov yog qee cov ncauj lus kom ntxaws txog cov khoom:
Kev Siv: Cotinine Rapid Test Self Test tsuas yog siv rau kev kuaj mob hauv vitro thiab kuaj pom zoo ntawm Cotinine hauv cov zis. Cov reagent no muab cov txiaj ntsig kev soj ntsuam ua ntej, tab sis cov txheej txheem tshuaj lom neeg tshwj xeeb yuav tsum tau siv kom tau txais cov txiaj ntsig kev ntsuas pom tseeb.
Lub hauv paus ntsiab lus: Cotinine yog thawj theem metabolite ntawm nicotine thiab alkaloid lom. Thaum tib neeg lub cev los rau hauv kev sib cuag nrog nicotine, nws nkoos lub autonomic paj hlwb thiab central paj hlwb. Nicotine yog ib yam tshuaj uas yuav luag txhua tus tswvcuab hauv zej zog kev haus luam yeeb tuaj rau hauv kev sib cuag nrog, txawm tias los ntawm kev sib cuag ncaj qha lossis nqus tau ob txhais tes. Ntxiv nrog rau kev haus luam yeeb, nicotine kuj tseem muaj nyob rau hauv kev lag luam raws li cov khoom siv hauv kev haus luam yeeb hloov kev kho mob xws li cov pos hniav nicotine, cov tshuaj pleev ib ce, thiab tshuaj tsuag qhov ntswg. Hauv 24- teev cov zis, kwv yees li 5% ntawm cov tshuaj nicotine tau tawm hauv cov tshuaj tsis hloov pauv, 10% yog tawm hauv daim ntawv cotinine, thiab 35% yog tawm hauv daim ntawv ntawm hydroxycotinine; Cov concentration ntawm lwm cov metabolites ntseeg tau tias tsawg dua 5%. Txawm hais tias cotinine suav hais tias yog ib qho tsis muaj zog metabolite, nws qhov kev tshem tawm yog ruaj khov dua li nicotine thiab feem ntau nyob ntawm cov zis pH. Yog li ntawd, Cotinine yog suav tias yog biomarker zoo rau kev txiav txim siab siv nicotine. Lub plasma ib nrab-lub neej ntawm nicotine yog kwv yees li 60 feeb tom qab nqus tau los yog txhaj tshuaj intramuscular. Nicotine thiab cotinine raug tshem tawm sai ntawm lub raum; Ntawm lub qhov rai tshawb pom cov zis ntawm Cotinine (txiav theem ntawm 200 ng / mL), nws xav tias cov txiaj ntsig zoo yuav tshwm sim hauv 2-3 hnub tom qab siv nicotine.
