Kumvetsa kusaganizira zowonongeka kungakhale kosokoneza. Komabe, ndi mbali yofunikira kumvetsetsa khalidwe ndi kulondola kwa mayesero a zachipatala. Kulephera koyambirira kumakuuzani zomwe zimatanthauza ngati mutayesa matenda odwala. Ichi ndi chizindikiro cha momwe zolinga zowonetsera zoipa ziliri zolondola. M'mawu ena, zimakuuzani momwe zilili kuti mulibe matendawa .
Cholakwika chenichenicho chimatanthauzidwa ngati chiwerengero cha zifukwa zenizeni (anthu amene amayesa omwe alibe omwe ali ndi kachilomboka) ogawanika ndi chiŵerengero cha anthu omwe amayesa zoipa. Zimasiyana ndi kuyesayesa, kuyerekezera , komanso kufalikira kwa matenda monga momwe mukuonera mu chitsanzo pansipa. Chifukwa cha kudalira matenda omwe amapezeka m'deralo kumene amagwira ntchito, kulingalira kuti chinthu cholakwika chonchi ndi chovuta. Madokotala ambiri sangakhoze kukupatsani chiwerengero cha chinyengo cholakwika chotsatira pamene mukulowa mayesero aliwonse - ngakhale atadziwa kukhudzidwa ndi zenizeni.
Zolemba Zina: NPV
Chitsanzo
Ngati mayeso a chlamydia ali ndi 80% othandizira & 80% enieni mu chiwerengero cha 100 ndi chlamydia kuchuluka kwa 10%:
8 mwa khumi aliwonse yeseso yesero yabwino
72 mwa makumi asanu ndi atatu (90) aliwonse amthendayi
Kuchokera kwa mayesero osayera 74, 82 ndi zolakwika zenizeni ndipo 2 ndizolakwika. Chifukwa chake, nambala yolakwika (NPV) idzakhala 97% (72/74). Anthu okwana 97% omwe amayesa zoipa sangakhale olakwika kwa chlamydia.

Mosiyana, ngati mayeso omwewo akuperekedwa kwa anthu okhala ndi chlamydia 40:
32 mwa 40 ofunika zenizeni zowona zabwino
40 mwa makumi asanu ndi limodzi (60) mwachinyengo choyesera
Kuchokera ku mayeso 48 osayera, 8 ndizolakwika. Izi zikutanthawuza kuti chinthu cholakwika choyenera ndi 83% (40/48).
Mmene Zinthu Zosiyanasiyana Zimakhudzira Mtengo Wosasamala
Ndalama zowonongeka zowonongeka zimapita pansi pamene matenda akufala kwambiri.
Mosiyana, mtengo wodzitetezera wabwino umapita mmwamba.
Mofananamo, mayesero okhudzidwa kwambiri amachititsa kuti kusayenerera kwakukulu kuwonjezeke. Ndicho chifukwa pali zolakwika zochepa. (Anthu ambiri omwe ali ndi mayesero abwino omwe ali ndi chitsimikiziro pamayeso apamwamba). Mosiyana, mayesero apamwamba ndi ofunikira kwambiri. Ndi mayesero amenewa, ndizochepa zonyenga. Zapamwamba kwambiri, anthu ambiri omwe ali ndi mayesero olakwika alibe.
