Adadin kamuwa da cutar a duniya ya ci gaba da hauhawa tun bayan barkewar cutar ta COVID-19.Ya zuwa Satumba 2021, adadin wadanda suka mutu a duniya daga COVID-19 ya wuce miliyan 4.5, tare da fiye da miliyan 222.
COVID-19 mai tsanani ne, kuma ba za mu iya shakatawa ba.Ganowa da wuri, bayar da rahoto da wuri, keɓewa da wuri da magani da wuri sun zama dole don yanke hanyar watsa kwayar cutar da sauri.
Don haka ta yaya ake gano Novel Coronavirus Virus?
Gano kwayar cutar COVID-19 nucleic acid gwaji ne da tantance wadanda aka tabbatar sun kamu da COVID-19, wadanda ake zargin COVID-19 da wadanda suka kamu da asymptomatic ta hanyoyin dakin gwaje-gwaje.
1. Fluorescence ainihin hanyar PCR
Hanyar PCR tana nufin amsawar sarkar polymerase, wanda ke ƙara ƙanƙantar adadin DNA.Don gano sabon coronavirus, kamar yadda labari Coronavirus ƙwayar cuta ce ta RNA, kwayar cutar ta RNA tana buƙatar juyawa zuwa DNA kafin gano PCR.
Ka'idar gano PCR mai haske shine: tare da ci gaban PCR, samfuran amsawa suna ci gaba da tarawa, kuma ƙarfin siginar walƙiya shima yana ƙaruwa daidai gwargwado.A ƙarshe, an sami madaidaicin ƙarar haske ta hanyar sa ido kan canjin adadin samfur ta canjin ƙarfin haske.Wannan a halin yanzu ita ce hanyar da aka fi amfani da ita don gwajin gwajin nucleic acid na coronavirus.
Koyaya, ƙwayoyin cuta na RNA suna da sauƙin lalacewa idan ba a kiyaye su da kyau ba ko ƙaddamar da su don gwaji cikin lokaci.Sabili da haka, bayan samun samfuran marasa lafiya, suna buƙatar adana su a daidaitaccen tsari kuma a gwada su da wuri-wuri.In ba haka ba, yana yiwuwa ya haifar da sakamakon gwajin da ba daidai ba.
Bututun samfurin ƙwayoyin cuta (Ana amfani da su don tarin, jigilar kayayyaki da adana samfuran ƙwayoyin cuta na DNA/RNA.)
2. Haɗaɗɗen bincike anchored polymerization sequencing hanyar
Wannan gwajin yana amfani da na'urori na musamman don gano jerin kwayoyin halittar da DNA nanospheres ke ɗauka akan jerin nunin faifai.
Hankalin wannan gwajin yana da girma, kuma ba shi da sauƙi a rasa ganewar asali, amma sakamakon kuma yana da sauƙin shafar abubuwa daban-daban kuma ba daidai ba.
3. Thermostatic haɓaka guntu Hanyar
Ƙa'idar ganowa ta dogara ne akan haɗin haɗin acid nucleic tsakanin haɓaka hanyar ganowa, ana iya amfani da shi don ƙididdige ƙididdiga ko ƙididdiga na acid nucleic a jikin rayayyun halittu.
4. Virus antibody ganowa
Ana amfani da reagents don gano ƙwayoyin rigakafin IgM ko IgG waɗanda jikin ɗan adam ke samarwa bayan kwayar cutar ta shiga cikin jiki.Kwayoyin rigakafin IgM suna bayyana a baya kuma IgG rigakafi suna bayyana daga baya.
5. Hanyar zinariya ta Colloidal
Hanyar zinare ta colloidal ita ce a yi amfani da takarda gwajin gwal don ganowa, wanda galibi ana faɗa a takardar gwajin ganowa cikin sauri.Irin wannan jarrabawa yana cikin minti 10 ~ 15 ko fiye, yana iya samun sakamakon ganowa.
6. Chemiluminescence na Magnetic barbashi
Chemiluminescence shine immunoassay mai mahimmanci wanda za'a iya amfani dashi don tantance antigenicity na abubuwa.Hanyar magnetic barbashi chemiluminescence Hanyar dogara ne a kan chemiluminescence ganowa, ƙara Magnetic nanoparticles, sabõda haka, ganewa yana da mafi girma hankali da sauri ganewa gudun.
COVID-19 Nucleic acid gwajin VS antibody gwajin, wanda za a zaba?
Gwajin Nucleic acid har yanzu shine kawai gwaje-gwajen da aka yi amfani da su don tabbatar da cututtukan coronavirus Novel. Ga waɗanda ake zargi da kamuwa da cutar Coronavirus nucleic acid korau gwajin, ana iya amfani da gwajin antibody azaman ƙarin nunin gwaji.
Novel Coronavirus(2019-nCoV) Kit ɗin Gano Acid Nucleic Acid (Hanyar Fluorescence PCR), tsarkakewar Nucleic acid na samfuran samfuran 32 ana iya kammala shi cikin ƙasan mintuna 20.
