Ukuhlaziya ukuba khona kwezidakamizwa ngokuhlolwa kwezidakamizwa komchamo sekuyinsakavukela kochwepheshe abaningi. lapho indebe yokuqoqa umchamo ibizwa ngokufanele futhi ibizwa yonke indawo ngokuthi indebe yomchamo, ukubaluleka kokuhlolwa kwezidakamizwa akunakuncishiswa. ukuze kuqinisekiswe imiphumela yokuhlolwa kwezidakamizwa, izici eziningi kufanele zibh
- ubuhlobo bomklamo nezinkomishi zomchamo nokukhethwa kwazo.
ukwakheka kwesitsha somchamo kunomthelela oqondile ekulungeni nasekuphepheni kokuthathwa kwesampula lomchamo. lapho kukhethwa uhlobo olufanele lwesitsha somchamo, kufanele kucatshangelwe izici ezilandelayo:
Ukwakheka: izinhlobo zezipuni zokubilisa umchamo ezihlangabezana nezidingo ezijwayelekile zenziwa ngengilazi noma ngezinto zepulasitiki. Izinkomishi zokubilisa umchamo zepulasitiki zilula, ziyathuthwa, azinakuqhuma futhi zingalahlwa kodwa izinkomishi zokubilisa umchamo zengila
uhlobo lokuvala: indebe yomchamo esebenzayo kufanele ivale ngokuphelele ukuze kugwenywe ukungcola noma ukuvuza kwezilwane. Isembozo sokuvala sizovimba ukungcola okuvela emiphumeleni yemvelo kumakhemikhali omchamo angashintsha imiphumela yokuhlola.
ukubekwa uphawu lwesikali: izitsha ezimbalwa zomchamo zinophawu lwesikali olonga odokotela kanye nochwepheshe baselebhu umzamo njengoba bengalinganisa inani lomchamo oqoqiwe. lokhu kungase kube okubalulekile kwezinye izimo, ikakhulukazi uma kuziwa ekuhlolweni okudinga ukuhlaziywa kokuhlushwa kwezidakamizwa.
ukulahla: ukusebenzisa izinkomishi zomchamo ezilahlwayo kunomthelela omkhulu ekunciphiseni amathuba okutheleleka okuphambene, kusiza ekuqinisekiseni ukuthi lokho okuhlolwayo kuyisampula elisha futhi okubaluleke kakhulu kusiza ekugwemeni ukuthi amasampula amadala angathikamezi imiphumela esikhathini esizayo.
Inqubo ejwayelekile yokuqoqwa komchamo.
Ukuqoqwa kwesampula lomchamo kuyisinyathelo esibucayi kakhulu senqubo yokuhlola izidakamizwa. Ngezansi kunezinqubo zokusebenza ezijwayelekile zokunamathela ekuqoqweni kwesampula lomchamo ukuqinisekisa ubuqotho bayo:
ukulungiselela: ngaphambi kokuya ensimini ukuyoqoqa amasampula omchamo, abasebenzi bokuhlola kufanele baqoqe zonke izinto ezidingekayo ezifana nezinkomishi zokuqoqa umchamo, izinto zokubeka amalebula, amagilavu okuvikela, nesibulala-magciwane. zonke izinto kufanele zibe sesimweni esingenamithi.
ukwazisa umuntu ohlolwayo: ngaphambi kokuba kuthathwe isampula, umhloli kufanele achazele umuntu ohlolwayo izinhloso zokuqoqwa kanye namasu okufanele asetshenziswe nokuthi yini okufanele igwenywe ukuze akhululeke ekucindezelekeni kwengqondo nasekungabazeni.
Uma umuntu eqala ukuchama, kufanele asebenzise umchamo ophakathi nomfula, okuwumkhuba lapho umuntu ekhipha khona umchamo othile ukuze avimbele ukungcoliswa kwendebe ye-pus noma isampula lomchamo ngemva kokuchama.
ukuhlonza nokufaka amalebula amasampula: kubalulekile ukubhala igama, isikhathi sokuqoqwa, neminye imininingwane ebalulekile esikhwameni somchamo esiyinyumba esizofakwa ukuze sihlaziywe kamuva kanye nesampula lomchamo eliqoqwe ngesikhathi senqubo.
3, ukuphathwa nokuthuthwa kwamasampula
izinqubo zokugcina kanye nezokuthutha amasampula omchamo zibaluleke ngokulinganayo lapho kuhloswe ngemiphumela yokuhlola enembile.
mayelana nokugcinwa: akukho bungozi bokugcina amasampula omchamo ekamelweni lokushisa kude nelanga nasezindaweni eziphakeme ngoba lokhu kungashintsha ukwakheka komchamo. ezimweni zokugcina isikhathi eside, isampula lingagcinwa esiqandisini, okungcono cishe cishe ku-4°c.
ukuhlaziya amasampula ngesikhathi sangempela. ngemva kokuqoqa amasampula omchamo ukuze ahlolwe, kufanele athunyelwe ngokushesha elabhorethri, ngokuvamile kungakapheli amahora angu-24. Ukwehluleka ukwenza ukuhlolwa ngesikhathi esinconyiwe kubangela ukuthi izingxenye zomchamo ziqhekeke, ngaleyo ndlela kunciphise ukuzwela
ukugwema ukungcola: kubalulekile ukuqinisekisa ukuthi indebe yomchamo ivaliwe kahle ukuze kugwenywe izinto zangaphandle ezingangcolisa isampula ngesikhathi sokuthuthwa kwesampula. ngesikhathi sokuthutha, kubalulekile futhi ukuthi isampula lingawi noma lonakaliswe nganoma iyiphi indlela.
ukuhlolwa kwaselebhu
inqubo yokuhlaziywa kwe-urine drug test yesampula lomchamo iyisigaba sokugcina senqubo yokuqinisekisa yokuhlolwa okuhloswe ngayo umlando wokusetshenziswa kwezinto ze-dhug. izici ezibalulekile ezinjengokuthi, kulokhu kusiza ukufeza imiphumela ethembekile:
izinqubo zokusebenza ezijwayelekile: zonke izibhedlela kufanele zibe nezimfuneko eziqondile ukuze ubufakazi obuqoqwe ekwamukeleni amasampula, ekucubunguleni nasekuhloleni bungalahleki ngenxa yokungagcini izinqubo zokusebenza ezijwayelekile (i-sops).
izindlela ezifanele zokuhlola izidakamizwa: ukusetshenziswa kwezidakamizwa kungenziwa ngezindlela ezihlukahlukene; kuhlanganise kodwa kungaphelelanga, ekuhlolweni komzimba nokwe-GC-MS. izindlela ezifanele zokuhlola izidakamizwa zingathuthukisa ukuthembeka kwemiphumela ngokuya ngokuzwela nokukhethekile.
Ukulinganisa izinsimbi: Ukulinganisa njalo nokuhlala njalo nokugcinwa kwemishini yokuhlola yaselebhu kubaluleke kakhulu ekusebenzeni nasekucaciseni. Lokhu kunjalo ikakhulukazi ekuqinisekiseni okungokwengqikithi kokuhlolwa kwezidakamizwa ngaphakathi kwesampula elihanjiselwe ukuhlolwa.
Ukulawulwa kwekhwalithi: kungaba nengqondo ukuthi kusetshenziswe izinqubo eziqinile ze-QA/qc futhi kukhiqizwe imibiko eningiliziwe mayelana nokuhlolwa kwangaphakathi nangaphandle kwe-QA kwedatha yokuhlola yaselebhu.
6, isiphetho
akungabazeki ukuthi izinkomishi zomchamo ziyizikhwama ezingangeni manzi uma kuziwa kunoma yikuphi ukuklama okusebenzayo, ukusetshenziswa, ukuqoqwa kwesampula nokuhlolwa kwelabhorethri ngenkathi kwenziwa ukuhlolwa kwezidakamizwa. Kunjalo nangokuhlolwa kwezidakamizwa ngomchamo: uma kuhambisana nezinqubo zokusebenza
