Rheumatoid vaega (RF)

Rheumatoid factor (RF) o se suʻega toto e fua ai le aofaʻi o le RF antibody i le toto.

O le tele o taimi, o le toto e toso mai le uaua o loʻo tu i totonu o le tulilima poʻo tua o le lima.

I tama meamea poʻo tamaiti laiti, e mafai ona faʻaaoga se mea faigaluega maai e taʻu o le lancet e tui ai le paʻu.

• E faʻaputuputu le toto i se tamaʻi paipa tioata e taʻu o le paipa, pe faʻasolosolo luga o se fasi pepa faʻasolosolo.
• O se fusi e tuu i luga o le nofoaga e taofi ai se toto.

Tele o taimi, e te le tau faia ni laʻasaga faʻapitoa aʻo leʻi oʻo i lenei suʻega.

E te ono lagonaina sina tiga pe o se tiga pe a tuu le nila. E te ono lagonaina foi le tataina o le loto i le nofoaga pe a uma ona tosoina le toto.

O lenei suʻega e masani ona faʻaaoga e fesoasoani ai i le faʻailoaina o le rheumatoid arthritis poʻo le Sjögren syndrome.

O iʻuga e masani ona lipotia mai i se tasi o auala e lua:

• Taua, masani maualalo ifo i le 15 IU / mL
• Titer, masani maualalo ifo i le 1:80 (1 i le 80)

Afai o le iʻuga e sili atu nai lo le tulaga masani, e lelei. O le maualalo numera (iʻuga le lelei) o le tele o taimi o lona uiga e te le maua i le rheumatoid gugu poʻo le Sjögren syndrome. Ae ui i lea, o nisi tagata o loʻo i ai nei tulaga o loʻo iai pea le le lelei pe maualalo le RF.

E masani ona fesuisuiaʻi vaega eseese o tau masani ile falefaigaluega eseese. Talanoa i lau soifua maloloina e uiga i le uiga o au faʻapitoa suʻega iʻuga.

O se faʻaiuga le lelei o lona uiga o le suʻega e lelei, o lona uiga o se maualuga maualuga o le RF ua maua i lou toto.

• Tele o tagata e maua i le rheumatoid gugu poʻo le Sjögren syndrome e lelei a latou suʻega RF.
• O le maualuga o le tulaga, o le sili atu ono o se tasi o nei tulaga o loʻo i ai. O loʻo iai foʻi isi suʻega mo nei faʻamaʻi e fesoasoani e fai ai le faʻamaoniga.
• E leʻo tagata uma e maualuga le maualuga ole RF e maua ile rheumatoid arthritis poʻo le Sjögren syndrome.

E tatau foʻi ona fai se suʻesuʻega ile toto (anti-CCP antibody), e fesoasoani ai ile faʻailoaina o le gugu rheumatoid (RA). Aneti-CCP antibody e sili atu faʻapitoa mo RA nai lo RF. O se faʻataʻitaʻiga lelei mo le CCP antibody o lona uiga o le RA atonu o le saʻo faʻamaʻi.

Tagata e iai faʻamaʻi nei e ono maualuga foʻi le maualuga ole RF.

• Hepatitis C
• Systemic lupus erythematosus
• Dermatomyositis ma polymyositis
• Sarcoidosis
• Fefiloi cryoglobulinemia
• Faʻafefiloi fesoʻotaʻiga maʻi

Maualuga-nai lo-masani tulaga o RF ono vaʻaia i tagata ma isi faʻafitauli faʻafomaʻi. Peitai, o nei maualuga RF tulaga e le mafai ona faʻaaogaina e faʻamaonia ai isi nei tulaga:

• AIDS, hepatitis, fulū, faʻamaʻi mononucleosis, ma isi siama viral
• Nisi maʻi fatugaʻo
• Endocarditis, tuberculosis, ma isi siama siama
• Faʻamaʻi pipisi
• Leukemia, tele myeloma, ma isi kanesa
• Faʻamaʻi faaumiumi o le mama
• Faamai faaumiumi o le ate

I nisi tulaga, o tagata e maloloina ma e leai se isi faʻafitauli faʻafomaʻi o le a maua se maualuga maualuga-nai lo-masani RF tulaga.

• Tofotofoga toto
