Ziziphi iimvavanyo ngcono ukukhulelwa, ukukhetha njani?

kuza ixesha xa kukho ukulibaziseka ngenyanga kubomi phantse yonke umfazi. Into yokuqala ethi qatha engqondweni - kukwenza olu vavanyo. Ukubona kwi kwikhemesti ukubonisa ubuninzi iibhokisi ezahlukeneyo kunye uvavanyo litmus, ucinga ukuba yintoni uvavanyo lokukhulelwa bhetele, oko kukuthi ngakumbi ngokuthembekileyo ukuqinisekisa ukuba ukukhulelwa na?

iintlobo zovavanyo

Ethandwa kakhulu ngumcu test, okanye uvavanyo komcu. Olu uvavanyo litmus, buzane nesisombululo okhethekileyo, yokusabela hCG (a hormone wandisa xa wena "kwi"). Loo uvavanyo uvikivwa kwingongoma ethile kwisingxobo umchamo imizuzwana 15-25. Emva kwemizuzu 5-10 isiphumo iyaboniswa. Ukuba strip yenye - akukho ukukhulelwa, bobabini - ekhulelwe. Nangona kunjalo, olu vavanyo kufuneka wenziwe lomchamo kusasa. Yena uthembekile, kodwa yonke loo nto ixhomekeke kule umenzi kwaye loluphi uhlobo reagent. Ukuba ongayiqondiyo, ikhangeleka ngathi uvavanyo lokukhulelwa positive, uvavanyo ifoto emva kokuba isicelo ingafunyanwa kwi ezahlukeneyo amaqonga oomama.

Uvavanyo cassette (tablet). Ukuba ucinga nton ngokui uvavanyo lokukhulelwa ngcono, ngoko olu vavanyo luza kunceda ngqo ukhulelwe okanye hayi. It is a ibhokisi zeplastiki iiwindow amabini kunye sokukhetha umbala. Ngaphakathi kuyo ngumcu test eqhelekileyo, kodwa iindleko lovavanyo cassette ibiza kakhulu. Ixabiso ngenxa yokuba kulula ukuyisebenzisa: oko akufuneki kuthi xhaxhe kwi umchamo - a sokukhetha umbala athontsize kwi window setyhula, yaye emva kwemizuzu 5-8 isiphumo kwi bhokisi ibonakala. Okunye olu vavanyo kungashiywa kwimemori - ukuba iziphumo ezidibanisayo.

test Jet. Olu luhlobo olutsha test. Kuba ixabiso oko elucwecweni izihlandlo eziliqela ezibiza kakhulu, kodwa amaxesha amaninzi ezikumgangatho ophezulu. Ubume be-nto intsonkothe ngaphezulu kunayo flat ezilula. Ilaphu imadlana zidla umchamo de intonga buzane a reagent, uze emva koko ibonisa isiphumo. Olu vavanyo Kulula ukusetyenziswa ukuze ukuba akanayo naphi ukuba dunk, ababambeleyo nje jet.

Ukuba akukwazi ukubona oko ukukhulelwa abahlele ngcono, ndithi ngaphandle kwamathandabuzo ngakumbi - elektroniki. ukuba bavele kutshanje. Olu luguqulelo olunzima kakhulu uvavanyo. Nguye nalo luyabiza, ekubeni yechaneke ngaphezulu. Ngenxa yoko HIV, i-screen uboniswa "+" okanye "« ikhulelwe ", kunye ezimbi - '-' ne 'akakhulelwanga". Zininzi elixhomekekileyo, ukususela hCG amanqanaba ifanele ibe phakathi kwe-10 ne UMama, yaye oko kunokwenziwa 4-5 ngemihla ebingaphambi kokulityaziswa.

Yintoni uvavanyo lokukhulelwa kungcono ukukhetha phakathi elektroniki

Kukho iimvavanyo ezininzi ezahlukeneyo elektroniki. Ngokuqhelekileyo ibonisa kuphela ubukho / ukungabikho lokukhulelwa. Kukho abo ezibonakalisa ixesha elingakanani sele idlule ukususela ngomhla ukukhulelwa. Kungathatha ukuya ezisibhozo kwiiveki zokukhulelwa. iimvavanyo Kutsha nje kuye khona, 'sibona' kunye nesini wosana. Loo uvavanyo kungenziwa ukusuka elesibhozo ngeveki ezingamashumi amathathu anesine. iindlela ezinjalo uxilongo ekhaya ukususela 300 ukuya 1000 engange. Selilixesha elifutshane eyaziwa eRashiya lafumana uvavanyo esebenza. Ukuba kukho iingxaki akhulelwe amathandabuzo, apho kungekho mvavanyo ukuba ukukhulelwa kubhetele ukuba uthenge, uze wenze ukuthenga phezu Internet, iyalele nje uvavanyo esebenza. Le cassette ne USB-isinxibelelanisi (isiphumo siboniswe screen), nto leyo lifakwa iCartridge (kuquka zazo ezimashumi mabini). Ukuba impendulo ngu hayi, ukongezelela ziyilwe elilungileyo iintsuku ekumitheni, ukuba HIV, Ixesha yokukhulelwa. Kuba ixabiso asingabo kakhulu eninzi ngaphezu ezilula elektroniki - evela engange 700 isethi nganye.
