Ukuhlolwa kwe-Widal

Uhlolojikelele

Iyini i-Widal Test?

Ukubaluleka kokuhlolwa kwe-Widal

Ukuhlolwa kwe-Widal kudlala indima ebalulekile kulokhu:

• Ukuxilongwa Kwangaphambi Kwesifo Se-Typhoid kanye Ne-Paratyphoid Fever: Kubalulekile ukuhlonza lezi zifo ezindaweni lapho zivame khona, okuvumela ukungenelela okufika ngesikhathi.
• Ukwehlukanisa Amagciwane Asebenzayo Ekuchayekeni Okudlule: Ngokulinganisa amazinga e-antibody, ukuhlola kusiza ukuhlukanisa phakathi kwezifo zamanje kanye nokuchayeka kwangaphambilini ku-Salmonella.
• Izinqumo Zokwelashwa Eziqondisayo: Imiphumela enembile isiza abahlinzeki bezokunakekelwa kwempilo ekukhetheni izindlela zokwelapha ezifanele, ukunciphisa ingozi yezinkinga kanye nokuvimbela ukusabalala kwesifo.

I-Widal Test isetshenziselwa ini?

Ukuhlolwa kwe-Widal kusetshenziselwa ukuxilongwa kwe-enteric fever, ngokuyinhloko ebangelwa i-Salmonella Typhi kanye ne-Salmonella Paratyphi. Idlala indima ebalulekile ku:

• Ukuxilonga I-Typhoid ne-Paratyphoid Fever: Ukuhlolwa kwe-Widal kusiza ukuqinisekisa izifo zeTypoid neParatyphoid kubantu ababonisa izimpawu, ukuqinisekisa ukungenelela nokwelashwa okufika ngesikhathi.
• Ukuqapha Ukuqubuka: Ezindaweni ezinokuthuthwa kwendle okungekuhle, ukuhlolwa kwe-Widal kubalulekile ukuze kulandelelwe ukuqubuka kwezifo, kusiza emizamweni yezempilo yomphakathi.
• Ukuhlola Amacala Asolwayo: Ezilungiselelweni ezinomkhawulo wensiza lapho izinketho zokuxilonga ezithuthukisiwe zingase zingatholakali, ukuhlolwa kwe-Widal kubalulekile ukuze kuhlolwe izimo ezisolisayo ze-enteric fever kanye nokusiza ekuthathweni kwezinqumo zomtholampilo.

Ukulungiselela Isivivinyo

Awekho amalungiselelo athile adingekayo ohlolo lwe-Widal. Nokho:

• Yazisa udokotela wakho nganoma yiziphi izifo noma imithi eqhubekayo, njengoba ingase ithinte imiphumela.
• Isampula yegazi elilodwa ngokuvamile lanele ukuhlolwa.

Inqubo Yokuhlola I-Widal

Ukuhlolwa kwegazi kwe-Widal kuhlanganisa lezi zinyathelo ezilandelayo:

• Iqoqo Lesampula Legazi: Uchwepheshe wezokunakekelwa kwempilo uzodonsa inani elincane legazi emthanjeni osengalweni, ngokuvamile ngenqubo esheshayo nelula.
• Ukuhlaziywa Kwelebhu: Isampula yegazi libe selihlaziywa elabhorethri ukuze kutholwe ubukhona namazinga amasosha omzimba ngokumelene nama-antigen O no-H e-Salmonella.
• Ukuhunyushwa: Imiphumela ibikwa njengama-antibody titer, abonisa ukuhlangana kwamasosha omzimba athile egazini, okusiza ukunquma ukuthi ukutheleleka kuyasebenza yini.

Le nqubo iqondile, ayihlaseli, futhi ngokuvamile ithatha amaminithi ambalwa nje ukuqeda.

I-Widal Test Normal Range

Ukuhlolwa kwe-Widal ngokuvamile kubonisa ama-antibody titer avamile e-Salmonella Typhi kanye ne-Salmonella Paratyphi antigens ngaphakathi kobubanzi obulandelayo: Ku-O (somatic) antigen, ama-titer avamile ngokuvamile aphakathi kuka-1:40 no-1:80. Ngokufanayo, ku-H (flagellar) antigen, ububanzi obujwayelekile bubuye bube ngu-1:40 ukuya ku-1:80. Lawa manani akhombisa ukungabikho kokutheleleka kwakamuva noma okusebenzayo. Ama-titers angaphezu kuka-1:160 kunoma iyiphi i-antigen angase abonise ukutheleleka okungenzeka okusebenzayo, futhi ukunyuka okuphawulekayo kwamanani e-titer kusukela kusampula yokuqala kuya kweyesibili eqoqwe emavikini angu-1-2 kamuva kubhekwa njengokusikisela kokutheleleka okuqhubekayo.

Ukuhunyushwa kwemiphumela yokuhlolwa kwe-Widal

Ukuchazwa kwemiphumela yokuhlolwa kwe-Widal kuncike emazingeni e-titer amasosha omzimba ngokumelene nama-antigen e-Salmonella Typhi kanye ne-Salmonella Paratyphi, kanye nokuba khona kwezimpawu. Ngezansi indlela ngokuvamile ehunyushwa ngayo imiphumela:

• Izinhlamvu eziphansi (1:40 kuye ku-1:80): Ivamise ukukhombisa ukuthi akukho ukutheleleka kwakamuva noma okusebenzayo. Le miphumela ingase iphakamise ukuchayeka esikhathini esidlule noma ukungatheleleki kwemvelo kodwa ayihlotshaniswa nokutheleleka okusebenzayo, ikakhulukazi uma zingekho izimpawu.
• Izinhlamvu Eziphakeme (Ngenhla 1:160): Phakamisa ukutheleleka okungenzeka okusebenzayo nge-Salmonella Typhi noma i-Salmonella Paratyphi, ikakhulukazi uma womabili ama-antigen titer o-O no-H ephakanyisiwe.
• Ukwenyuka Okuphindwe Kane Kumasampuli Abhanqiwe: Ukukhuphuka okuphindwe kane kwama-antibody titer phakathi kwamasampula amabili athathwe ngokuhlukana kwamaviki angu-1-2 kubonisa ngokuqinile ukutheleleka okukhona.
• Ukucatshangelwa kwezimpawu zomtholampilo: Ukuhlolwa kwe-Widal kufanele kuhunyushwe ngokuhambisana nezimpawu zomtholampilo, njengoba izinto ezingelona iqiniso noma ezingezinhle kungenzeka, ikakhulukazi ezindaweni ezihlala njalo noma ngokuchayeka ngaphambilini ku-Salmonella.

Izici Ezithonya Imiphumela Yokuhlolwa Kwe-Widal

Izinto ezimbalwa zingathonya ukunemba nokuchazwa kwemiphumela yokuhlolwa kwe-Widal:

• Umgomo Odlule: Abantu abagonyelwe i-typhoid fever bangase babonise ama-antibody titers aphakeme, ngisho nalapho kungekho ukutheleleka okusebenzayo.
• Izifo Ezidlule: Umlando wezifo zangaphambilini ze-Salmonella ungaholela kumasosha omzimba aphikelelayo egazini, okungenzeka abangele amanga.
• Ukusebenza kabusha kwe-Cross: Ukuhlolwa kwe-Widal kungase kuveze imiphumela engemihle uma amasosha omzimba ehlangana namanye amagciwane abangela izimpawu ezifanayo, njengezinhlobo ezithile zezifo ezibangelwa amagciwane.
• Isikhathi Sokuhlolwa: Ekuqaleni kwesikhathi sokutheleleka, amazinga e-antibody angase abe phansi kakhulu ukuthi angabonwa. Ukuhlolwa okuphindaphindiwe ngemva kwamaviki angu-1-2 kungase kudingeke ukuze kutholakale ukuxilongwa okunembile, ikakhulukazi uma izimpawu ziqhubeka.

Ukuhlolwa Okuhle kwe-Widal

Ukuhlolwa okuqondile kwe-Widal kubonisa ukuba khona kwamasosha omzimba alwa ne-Salmonella Typhi noma i-Salmonella Paratyphi, okuphakamisa ukutheleleka okukhona, njenge-typhoid noma i-paratyphoid fever. Ukuhlolwa kukala amazinga amasosha omzimba ngokumelene nama-antigen O (somatic) kanye no-H (flagellar) alawa magciwane egazini.

• I-Widal Test Positive Report: Uma umbiko wokuhlolwa kwe-Widal uthi positive, ubonisa ama-antibody titers aphakeme, ngokuvamile afinyelela ku-1:160 noma ngaphezulu. Lokhu kusikisela ukuthi umzimba usabela ngenkuthalo ekuthelelekeni. Kwezinye izimo, amasampula egazi abhanqiwe ayahlolwa ukuze kutholwe ukwanda okuphindwe kane kuma-antibody titers, okungase kuqinisekise ubukhona bokutheleleka okusebenzayo.
• I-Widal Test Positive Values: Lawa ma-antibody titers alandelayo ngokuvamile abonisa umphumela omuhle:
  • Ama-antigen titer ≥ 1:160
  • I-H antigen titers ≥ 1:160

Lezi zihloko eziphakeme ziphakamisa ukuthi umuntu uke wachayeka ku-Salmonella noma okwamanje ulwa nesifo, njenge-typhoid noma i-paratyphoid fever.

• I-Widal Test Positive Treatment: Lapho kuqinisekisiwe ukutheleleka okusebenzayo ngokuhlolwa kwe-Widal, ukwelashwa okufika ngesikhathi kwama-antibiotic kubalulekile. Imithi ejwayelekile ihlanganisa:
  • I-Ciprofloxacin: Ngamacala angeyona inkimbinkimbi.
  • I-Ceftriaxone: Ngezifo ezinzima noma izimo ezidinga ukwelashwa ngokufakwa emthanjeni.
  • I-Azithromycin: Ngezifo ezingatheni noma lapho amanye ama-antibiotic engase angafaneleki.

Ngaphezu kwama-antibiotics, ukunakekelwa okusekelayo, njengokugcina amanzi kanye nokulawula umkhuhlane, kubalulekile ekululameni kwesiguli.

Kubalulekile ukutolika umphumela wokuhlolwa kuka-Widal kanye nezimpawu zomtholampilo, njengoba kungase kube nemiphumela engemihle, ikakhulukazi kubantu abagonywe ngaphambilini noma abangenwe yi-Salmonella edlule.

Izinzuzo ze-Widal Test

• Ingabizi futhi Ilula: Ukuhlolwa kwe-Widal iyithuluzi lokuxilonga eliqondile nelithengekayo, elenza lifinyeleleke ekuxilongeni i-typhoid fever, ikakhulukazi kuzilungiselelo ezinomkhawulo wezinsiza.
• Iwusizo Ezindaweni Ezikude: Ukuhlolwa kunenzuzo ikakhulukazi ezifundeni ezinokufinyelela okulinganiselwe kumishini yokuxilonga ethuthukisiwe, okuvumela abahlinzeki bezempilo ukuthi babone izifo kusenesikhathi.
• Iqondisa Ukwelashwa Nokulawula Ukuqubuka: Ngokuhlonza izifo ze-typhoid noma i-paratyphoid, ukuhlolwa kwe-Widal kusiza ekwenzeni izinqumo zokwelashwa ezinolwazi futhi kusize ekulawuleni ukuqubuka, ukwehlisa ukusabalala kwesifo.
