Sidee lagu ogaan karaa Novel Coronavirus Virus (2019-nCoV)?

1 (1)

Tirada guud ee cudurrada iyo dhimashada ayaa sii kordheysa tan iyo markii uu faafay COVID-19.Laga soo bilaabo Sebtembar 2021, tirada dhimashada adduunka ee COVID-19 ayaa dhaaftay 4.5 milyan, in ka badan 222 milyan oo xaaladood.

COVID-19 waa halis, mana nasan karno.Ogaanshaha hore, warbixinta hore, go'doominta hore iyo daawaynta hore ayaa lagama maarmaan u ah si dhakhso ah loo gooyo dariiqa gudbinta fayraska.

Haddaba sidee lagu ogaan karaa Novel Coronavirus Virus?

Ogaanshaha COVID-19 nucleic acid waa baaritaanka iyo baarista kiisaska COVID-19 ee la xaqiijiyay, kiisaska COVID-19 ee looga shakisan yahay iyo dadka asymptomatic-ka ah ee cudurka qaba iyadoo loo marayo hababka sheybaarka.

1. Fluorescence habka PCR-waqtiga dhabta ah

Habka PCR waxaa loola jeedaa falcelinta silsiladda polymerase, kaas oo si weyn u kordhiya xaddi yar oo DNA ah.Cilmi-baadhista cusub ee Coronavirus, maadaama uu novel Coronavirus yahay fayras RNA, fayraska RNA wuxuu u baahan yahay in si kale loogu rogo DNA ka hor intaan la ogaan PCR.

Mabda'a ogaanshaha PCR ee fluorescence waa: horumarka PCR, alaabada falcelinta waxay sii wadaan inay ururaan, iyo xoojinta calaamadaha fluorescence sidoo kale waxay kordhisaa si siman.Ugu dambeyntii, qalooca kor u qaadida fluorescence ayaa la helay iyadoo la kormeerayo isbeddelka tirada alaabta iyada oo loo marayo isbeddelka xoojinta fluorescence.Tani hadda waa habka ugu badan ee loo isticmaalo baaritaanada cusub ee Coronavirus nucleic acid.

Si kastaba ha ahaatee, fayrasyada RNA si fudud ayaa loo dhimaa haddii aan si habboon loo ilaalin ama aan loo gudbin si loo baaro waqtigeeda.Sidaa darteed, ka dib marka la helo muunado bukaan-socod ah, waxay u baahan yihiin in loo kaydiyo si habaysan oo la tijaabiyo sida ugu dhakhsaha badan.Haddii kale, waxay u badan tahay inay keento natiijooyin imtixaan oo aan sax ahayn.

Tubooyinka muunada fayraska (Waxaa loo isticmaalaa ururinta, rarida iyo kaydinta muunadaha fayraska DNA/RNA.)

2. Habka isku xigxiga ee isku xigxiga ee baadhista ku xidhan polymerization

Tijaabadani waxay inta badan adeegsataa qalab gaar ah si loo ogaado taxanaha hiddo-wadaha ee ay wataan nanospheres DNA-ga ee sawir-qaadista.

Dareenka baaritaankani waa mid sareeya, mana fududa in la seego cudurka, laakiin natiijadu waxay sidoo kale si fudud u saameeyaan arrimo kala duwan oo aan sax ahayn.

3. Habka qaboojinta heerkulbeegga

Mabda'a ogaanshaha waxay ku saleysan tahay isku dhafka isdhaxgalka ah ee asiidhyada nucleic-ka ee u dhexeeya horumarinta habka ogaanshaha, waxaa loo isticmaali karaa cabirka tayada ama tirada ee asiidhyada nucleic-ka ah ee jirka noolaha.

4. Ogaanshaha Virus-ka Antibody

Dib-u-hawlgalayaasha ogaanshaha ka-hortagga waxa loo isticmaalaa in lagu ogaado IgM ama IgG-ka-hortagga difaaca jirka ee uu soo saaro jirka bini'aadamka ka dib marka uu fayrasku galo jirka.Unugyada difaaca jirka ee IgM ayaa hore u soo baxa, IgG-ga difaaca ayaa soo baxa mar dambe.

5. Habka dahabka kolloidal

Habka dahabka kolloidhka ah waa in la isticmaalo warqadda tijaabada dahabka kolloidhka si loo ogaado, taas oo inta badan la sheego warqadda ogaanshaha degdega ah ee hadda.Baaritaanka noocaan ah wuxuu ku jiraa 10 ~ 15 daqiiqo ama inta badan, wuxuu heli karaa natiijada ogaanshaha.

6. Chemiluminescence ee qaybaha magnetic

Chemiluminescence waa immunoassay aad xasaasi u ah oo loo isticmaali karo in lagu go'aamiyo antigenicity ee walxaha.Habka chemiluminescence particle magnetic wuxuu ku saleysan yahay ogaanshaha chemiluminescence, isagoo ku daraya nanoparticles magnetic, si ogaanshaha u yeesho dareen sare iyo xawaaraha ogaanshaha degdega ah.

Baaritaanka COVID-19 nucleic acid test VS antibody test, kee la doortaa?

Tijaabada aashitada nukliyeerka ayaa wali ah baaritaanada kaliya ee loo isticmaalo in lagu xaqiijiyo caabuqyada coronavirus-ka cusub

Novel Coronavirus(2019-nCoV) Qalabka Ogaanshaha Asiidhka Nukliyeerka (Habka Fluorescence PCR), Sifaynta Aashitada Nucleic ee 32 muunado waxa lagu dhamayn karaa wax yar 20 daqiiqo gudahood.
