I-rheumatoid factor: yintoni, yintoni eyenziweyo kunye nendlela yokuqonda iziphumo

Umxholo

• Luqhutywa njani uviwo
• Inokuba yintoni into eguqulweyo yethambo

Into ye-rheumatoid yinto enokuthi iveliswe kwezinye izifo ezenzekelayo kwaye iphendule ngokuchasene ne-IgG, yenze amajoni omzimba ahlasele kwaye atshabalalise izicubu ezinempilo, ezinjenge-cartilage edibeneyo, umzekelo.

Ke, ukuchongwa kwento ye-rheumatoid egazini kubalulekile ukuphanda ubukho bezifo ezisebenza ngokuzimela, ezinje nge-lupus, i-rheumatoid arthritis okanye isifo se-Sjögren's, esidla ngokubonisa amaxabiso aphezulu ale protein.

Luqhutywa njani uviwo

Umlinganiso we-rheumatoid factor wenziwa kwisampulu yegazi encinci ekufuneka iqokelelwe elebhu emva kokuzila ukutya ubuncinci iiyure ezi-4.

Igazi eliqokelelweyo lithunyelwa elebhu, apho uvavanyo luya kwenziwa khona ukuze kuchongwe ubukho besifo samathambo. Kuxhomekeke kwilabhoratri, ukuchongwa kwento ye-rheumatoid yenziwa ngovavanyo lwe-latex okanye uvavanyo lwe-Waaler-Rose, apho i-reagent ethile yovavanyo ngalunye yongezwa kwithontsi legazi kwisigulana, emva koko ilungelelaniswe kwaye emva kwemizuzu emi-3 emi-5, jonga ubumbano. Ukuba ubukho bezigaqa buqinisekisiwe, uvavanyo luthi luchanekile, kwaye kunyanzelekile ukuba kwenziwe olunye uxinzelelo ukuqinisekisa inani lesifo samathambo esikhoyo kwaye, ngenxa yoko, inqanaba lesi sifo.

Njengoko ezi mvavanyo zinokuthatha ixesha elininzi, uvavanyo oluzenzekelayo, olubizwa ngokuba yi-nephelometry, lusebenza ngakumbi kwizenzo zaselebhu, njengoko ivumela iimvavanyo ezininzi ukuba zenziwe ngaxeshanye kwaye ukuxutywa kwenziwa ngokuzenzekelayo, kukwaziswa kuphela kwilabhoratri yobuchwephesha kwaye ugqirha iziphumo zoviwo.

Iziphumo zinikwa izihloko, ngesihloko ukuya kuthi ga kwi-1: 20 ithathwa njengesiqhelo. Nangona kunjalo, iziphumo ezingaphezulu kwe-1: 20 azibonisi ukuba sisifo samathambo, kwaye ugqirha kufuneka ayalele ezinye iimvavanyo.

Inokuba yintoni into eguqulweyo yethambo

Uvavanyo lwe-rheumatoid factor luyathandeka xa amaxabiso alo angaphezulu kwe-1: 80, ebonisa ukuba unesifo samathambo, okanye phakathi kwe-1: 20 kunye ne-1: 80, enokuthetha ukubakho kwezinye izifo, ezinje:

• Ilupus erythematosus;
• Isifo sikaSjogren;
• IVasculitis;
• Iscleroderma;
• Isifo sephepha;
• Mononucleosis;
• Negcushuwa;
• Isifo seengcongconi;
• Iingxaki zesibindi;
• Usulelo lwentliziyo;
• Ileukemia.

Nangona kunjalo, njengoko into yesifo samathambo inokutshintshwa kubantu abasempilweni, ugqirha unokuyalela ezinye iimvavanyo ukuqinisekisa ubukho besifo esonyusa imeko. Ngenxa yokuba iziphumo zolu vavanyo zinzima kakhulu ukutolika, iziphumo kufuneka zihlale zivavanywa yingcali yethambo. Funda konke malunga neRheumatoid Arthritis.
