Uvavanyo lwegazi lweECA

Uvavanyo lwe-carcinoembryonic antigen (CEA) lilinganisela inqanaba le-CEA egazini. I-CEA yiprotein yesiqhelo efumaneka kwizicubu zomntwana okhulayo esibelekweni. Inqanaba legazi lale proteni liyanyamalala okanye lihle kakhulu emva kokuzalwa. Kubantu abadala, inqanaba elingaqhelekanga le-CEA linokuba luphawu lomhlaza.

Isampulu yegazi iyafuneka.

Ukutshaya kunokunyusa inqanaba le-CEA. Ukuba uyatshaya, ugqirha wakho angakuxelela ukuba uphephe ukwenza njalo okwexeshana ngaphambi kovavanyo.

Xa kufakwa inaliti ukutsala igazi, abanye abantu baziva iintlungu eziphakathi. Abanye baziva behlaba okanye behlaba kuphela. Emva koko, kunokubakho ukubetha okanye ukukrala kancinci. Oku kuya kuhamba kungekudala.

Olu vavanyo lwenziwa ukujonga impendulo kunyango emva koko kujongwe ukubuya kwekolon kunye neminye imihlaza efana nomhlaza wamachiza we-medullary kunye nomhlaza we-rectum, imiphunga, isifuba, isibindi, ipancreas, isisu kunye nee-ovari.

Ayisetyenziswanga kuvavanyo lokuvavanywa komhlaza kwaye akufuneki yenziwe ngaphandle kokuba kufunyaniswe isifo somhlaza.

Uluhlu oluqhelekileyo ngu-0 ukuya ku-2.5 ng / mL (0 ukuya ku-2.5 µg / L).

Kwabantu abatshayayo, amaxabiso aphezulu anokuqwalaselwa njengesiqhelo (0 ukuya ku-5 ng / mL, okanye 0 kuye ku-5 µg / L).

Inqanaba eliphezulu le-CEA kumntu osandula ukunyangwa umhlaza othile kunokuthetha ukuba umhlaza ubuyile. Inqanaba eliphezulu kuneliqhelekileyo linokubangelwa zezi mhlaza zilandelayo:

• Umhlaza webele
• Umhlaza wamaphecana okuzala kunye nawokuchama
• Umhlaza wamathumbu
• Umhlaza wemiphunga
• Umhlaza wepancreatic
• Umhlaza wedlala lengqula

Ngaphezulu kwenqanaba eliqhelekileyo le-CEA kuphela alinakufumanisa umhlaza omtsha. Olunye uvavanyo luyafuneka.

Inqanaba elonyukayo le-CEA linokubakho ngenxa:

• Iingxaki zesibindi kunye ne-gallbladder, ezinjengokubola kwesibindi (i-cirrhosis), okanye ukudumba kwe-gallbladder (cholecystitis)
• Ukutshaya kakhulu
• Izifo zamathumbu ezivuthayo (ezinjenge-ulcerative colitis okanye i-diverticulitis)
• Usulelo lwemiphunga
• Ukudumba kwepancreas (pancreatitis)
• Isilonda esiswini

Akukho mngcipheko ubandakanyekileyo ekuthatheni igazi lakho. Imithambo kunye nemithambo iyahluka ngobukhulu ukusuka komnye umntu ukuya komnye nakwelinye icala lomzimba liye kwelinye. Ukuthatha igazi kwabanye abantu kunokuba nzima ngakumbi kunabanye.

Eminye imingcipheko enxulumene nokutsalwa kwegazi incinci kodwa inokubandakanya:

• Ukopha kakhulu (kunqabile)
• Ukufa isiqaqa okanye ukuziva ungenantloko
• Ukugqobhoza okuninzi ukufumana imithambo
• I-Hematoma (igazi eliqokelela phantsi kwesikhumba)
• Usulelo (umngcipheko omncinci nangaliphi na ixesha ulusu lwaphukile)
