Ọnụọgụ ọrịa na ọnwụ zuru ụwa ọnụ ka na-arị elu kemgbe ọrịa COVID-19 malitere.Dị ka nke Septemba 2021, ọnụ ọgụgụ ndị nwụrụ n'ụwa niile sitere na COVID-19 gafere nde 4.5, yana ihe karịrị nde 222.
COVID-19 dị njọ, anyị enweghị ike izuike.Nchọpụta mbụ, ịkọ akụkọ mbụ, ikewapụ oge mbụ na ọgwụgwọ mbụ dị mkpa iji kwụsị ngwa ngwa ụzọ mbufe nje a.
Yabụ kedu ka esi achọpụta Nje Virus Novel?
Nchọpụta COVID-19 nucleic acid bụ nnwale na nyocha nke ikpe COVID-19 enwetara, ndị a na-enyo enyo na COVID-19 na ndị butere ọrịa asymptomatic site na ụzọ ụlọ nyocha.
1. Fluorescence ezigbo oge PCR usoro
Usoro PCR na-ezo aka na mmeghachi omume yinye polymerase, nke na-abawanye ntakịrị DNA nke ukwuu.Maka nchọpụta Coronavirus ọhụrụ, dịka akwụkwọ akụkọ Coronavirus bụ nje RNA, nje virus RNA kwesịrị ka edegharịa ya na DNA tupu nchọpụta PCR.
Ụkpụrụ nke nchọpụta PCR fluorescence bụ: na ọganihu nke PCR, ngwaahịa mmeghachi omume na-aga n'ihu na-agbakọta, na ike nke mgbaàmà fluorescence na-abawanye kwa oke.N'ikpeazụ, a na-enweta ihe nrịbawanye nke fluorescence site na nyochaa mgbanwe nke ọnụọgụ ngwaahịa site na ngbanwe nke ike fluorescence.Nke a bụ usoro a na-ejikarị eme ihe maka nnwale coronavirus nucleic acid.
Agbanyeghị, nje RNA na-emebi ngwa ngwa ma ọ bụrụ na echekwabeghi ha nke ọma ma ọ bụ nyefee ya maka nyocha n'oge.Ya mere, mgbe ha nwetasịrị ihe nlele ndị ọrịa, ọ dị mkpa ka echekwa ha n'ụzọ ziri ezi ma nwalee ozugbo enwere ike.Ma ọ bụghị ya, ọ nwere ike ibute nsonaazụ ule na-ezighi ezi.

2. Usoro nleba anya jikọtara ọnụ nke polymerization usoro
Nnwale a na-ejikarị ngwa ndị pụrụ iche iji chọpụta usoro mkpụrụ ndụ ihe nketa nke DNA nanospheres na-ebu n'usoro ihe mmịfe.
Mmetụta nke ule a dị elu, ọ dịghịkwa mfe ịchọta nyocha, mana nsonaazụ na-emetụtakwa ihe dị iche iche ngwa ngwa na ezighi ezi.
3. Thermostatic amplification mgbawa usoro
Ụkpụrụ nchọpụta dabere na nchikota nke nucleic acids n'etiti mmepe nke usoro nchọpụta, enwere ike iji ya mee ihe maka nha qualitative ma ọ bụ quantitative nke nucleic acid n'ime ahụ nke ihe ndị dị ndụ.
4. Nchọpụta ihe mgbochi nje
A na-eji reagents nchọpụta ihe mgbochi iji chọpụta ọgwụ mgbochi IgM ma ọ bụ IgG nke ahụ mmadụ na-emepụta mgbe nje batara n'ime ahụ.Ọgwụ mgbochi IgM na-apụta na mbụ yana ọgwụ mgbochi IgG na-apụta ma emechaa.
5. Colloidal gold usoro
Usoro ọla edo nke colloidal bụ iji akwụkwọ nyocha ọla edo colloidal maka nchọpụta, nke a na-ekwukarị n'akwụkwọ nyocha ngwa ngwa ugbu a.Ụdị nyocha a dị na nkeji 10 ~ 15 ma ọ bụ karịa, nwere ike nweta nsonaazụ nchọpụta.
6. Chemiluminescence nke ihe ndọta
Chemiluminescence bụ immunoassay nke nwere mmetụta nke ukwuu nke enwere ike iji chọpụta antigenicity nke ihe.Usoro chemiluminescence magnetik sitere na nchọpụta chemiluminescence, na-agbakwunye nanoparticles magnetik, nke mere na nchọpụta ahụ nwere mmetụta dị elu na ọsọ nchọpụta ngwa ngwa.
Nnwale COVID-19 nucleic acid VS antibody test, nke ị ga-ahọrọ?
Nnwale nucleic acid ka bụ naanị ule eji akwado ọrịa coronavirus ọhụrụ. Maka ndị a na-enyo enyo maka ule coronavirus novel nucleic acid, enwere ike iji nnwale antibody dị ka ihe ngosi nnwale mgbakwunye.
Novel Coronavirus(2019-nCoV) Nucleic Acid Detection Kit (Fluorescence PCR Method), Nucleic acid ọcha nke sample 32 nwere ike mechaa n'ime ihe dị ka nkeji iri abụọ.
