Urease test: yintoni kunye nendlela eyenziwa ngayo

Umxholo

• Uvavanyo lwenziwa njani
• Usiqonda njani iziphumo

Uvavanyo lwe-urease luvavanyo lwaselebhu olusetyenziselwa ukufumanisa ibhaktiriya ngokufumanisa umsebenzi we-enzyme enokuthi ibenayo okanye ingenayo. I-Urease yi-enzyme ejongene nokwahlulwa kwe-urea ibe yi-ammonia kunye ne-bicarbonate, eyonyusa i-pH yendawo ekhoyo, ikhuthaza ukwanda kwayo.

Olu vavanyo lusetyenziswa ikakhulu ekuchongeni usulelo ngu Helicobacter pylori, okanye H. pylori, inoxanduva lweengxaki ezininzi, ezinje ngegastritis, esophagitis, duodenitis, ulcer kunye nomhlaza wesisu, ngenxa yesi sizathu. Ke, ukuba kukho urhano losulelo ngo H. pylori, i-gastroenterologist inokwenza uvavanyo lwe-urease ngexesha le-endoscopy. Ukuba kunjalo, unyango luqaliswa ngokukhawuleza ngenjongo yokuthintela isifo ukuba sikhule kwaye sinciphise iimpawu zomntu.

Uvavanyo lwenziwa njani

Xa uvavanyo lwe-urease lwenziwa njengesiqhelo selebhu, akukho kulungiselela kuyafuneka kuvavanyo. Nangona kunjalo, ukuba yenziwe ngexesha le-endoscopy, kubalulekile ukuba umntu alandele yonke imigaqo yoviwo, njengokuthintela ukusebenzisa iziyobisi ezichasayo nokuzila ukutya ubuncinci iiyure ezi-8.

Uvavanyo lwe-urease lwenziwa elabhoratri ngohlalutyo lwezinto eziqokelelweyo, kunye nokuzahlula kwe-microorganism kuqhutywa kunye novavanyo lokuchonga lwe-biochemical, phakathi kwabo uvavanyo lwe-urease. Ukwenza uvavanyo, i-microorganism ekhethiweyo igalelwe kwisithuba senkcubeko esiqukethe i-urea kunye nesalathi esibomvu se-pH. Emva koko kujongiwe ukuba ngaba lukhona utshintsho kumbala ophakathi okanye hayi, nto leyo ebonisa ubukho kunye nokungabikho kweentsholongwane.

Kwimeko yovavanyo lwe-urease ukukhangela usulelo ngu H. pylori, uvavanyo lwenziwa ngexesha lovavanyo oluphezulu lwe-endoscopy, oluvavanyo oluvavanya impilo yomqala kunye nesisu, ngaphandle kokubangela iintlungu okanye ukungonwabi kwisigulana kwaye iziphumo zinokuvavanywa kwimizuzu embalwa. Ngexesha loviwo, isiziba esincinci sodonga lwesisu siyasuswa sibekwe kwiflask ene-urea kunye nesalathiso se-pH. Ukuba emva kwemizuzu embalwa umbala ophakathi utshintsha umbala, uvavanyo luthi luchanekile, luqinisekisa usulelo ngo H. pylori. Jonga ukuba zeziphi iimpawu ezinokubonisa usulelo ngo H. pylori.

Usiqonda njani iziphumo

Iziphumo zovavanyo lwe-urease zinikwa ukusuka kutshintsho lombala kwaphakathi apho kuvavanyo lwenziwa khona. Ke, iziphumo zinokuba:

• Ezintle, xa ibhaktiriya ene-enzyme urease ikwazi ukuthoba urea, inika i-ammonia kunye ne-bicarbonate, le mpendulo ibonwa ngokutshintsha umbala wendawo, etshintsha ukusuka kumbala otyheli ukuya kupinki / bomvu.
• Ukungalunganga xa kungekho tshintsho kumbala ophakathi, obonisa ukuba intsholongwane ayinayo i-enzyme.

Kubalulekile ukuba iziphumo zitolikwe ngaphakathi kweeyure ezingama-24 ukuze kungabikho thuba leziphumo ezibubuxoki, ezo ke ngenxa yokuguga kweliphakathi, i-urea iqala ukuthotywa, enokutshintsha umbala.

Ukongeza ekuchongeni usulelo ngu Helicobacter pylori, Uvavanyo lwe-urease lwenziwa ukuchonga iibacteria ezininzi, kwaye uvavanyo lolo lukulungele I-Staphylococcus saprophyticus, I-Staphylococcus epidermidis, Iproteus spp. kwaye UKlebsiella pneumoniae, umzekelo.
