Ko e interferon gamma release assay (IGRA) ko ha sivi toto ke sio kapau ʻoku puke ha taha ʻi he fatafata vaivaí (TB). ʻOku tomuʻa pihia ʻi he TB ki muʻa ke puke ʻi he fokoutua TB.
Ko e pihia ʻi he TB (ʻa ia ʻoku toe ʻiloa ko e pihia tōmui ʻi he TB pe TB ʻmohe’) ko e taimi ia ʻokú ke maʻu ai ʻa e siemu TB ʻi ho sinó, ka ʻoku ʻikai kenau ʻai koe ke ke puke. Ko e sistemi maluʻi ho sinó ʻoku ne taʻofi ʻa e siemú mei hono fakatupunga ha faʻahinga maumau. ʻOku ʻikai ha ngaahi fakaʻilonga ʻo e pihia ʻi he TB pea ʻoku ʻikai lava ke paasi ʻa e siemú ki he niʻihi kehé.
Ko e pihia ʻi he TB ʻoku kehekehe ia mei he fokoutua TB ʻa ia ko e taimi ia ʻoku ʻā hake ai ʻa e siemu TB pe kaka hono tokolahí pea ʻai ai koe ke ke puke pea malava ke paasi ʻa e siemú ki he niʻihi kehé.
Kapau ʻoku hā mai mei he sivi toto IGRA ʻokú ke pihia ʻi he TB, ʻe lava ʻe hoʻo toketaá ke ʻoatu ha foʻiʻakau ke taʻofiʻaki ʻa e fokoutua TB.
Ko ha fakamatala lahiange fekauʻaki mo e pihia ʻi he TB ʻe lava ke maʻu ia ʻi heni: pihia ʻi he TB
ʻOku anga-fēfē hono fakahoko ʻa e IGRA?
Ko e IGRA ko ha sivi toto ʻa ia ʻoku fiemaʻu ha fanga kiʻi tesitiupi iiki toto ʻe 4. ʻE lava ke ke kai mo inu hangē ko e anga-mahení ki muʻa ʻi he siví. ʻOku ngāué ʻaki hono fua ʻa e anga ʻo e tali ʻa e kau sōtia maluʻi ʻo e sinó ki he siemú ʻokú ne fakatupunga ʻa e TB.
Kimuʻa ke fai hao sivi IGRA
Kātaki ʻai ke ʻilo ʻe he neesí pe ko e toketaá kapau ʻokú ke:
- moʻua ʻi ha niʻihi ʻo e ngaahi mahaki ʻokú ne fakavaivaiʻi ʻa e kau sōtia maluʻí hangē ko e HIV, kanisā, pe fokoutua ʻo e kofuuá
- ʻokú ke folo ha foʻiʻaku ʻokú ne uesia ho sisitemi maluʻí hangē ko e sitēloiti, (fakatātā peletinisouni), pe kimo (faitoʻo ki he kanisaá)
- mofi (>38° C) pe pihia ʻi ha mahaki ʻi he māhina kuo ʻosí, hangē ko e fulū, mīsele, pe ko hono maʻu ʻe he momokó ʻa e fatafatá
- naʻe fai hao faʻahinga huhu maluʻi ʻi he māhina kuo ʻosí
- naʻá ke moʻua ʻi he TB ʻi he kuo hilí pe fetuʻutaki mo ha taha naʻe maʻu ʻe he TB.
Hili hono fai ho sivi IGRA
Kapau ʻe positivi ʻa e ola hoʻo IGRA, ʻoku ala lava naʻá ke fetuʻutaki mo e siemu TB ʻi he kuo hilí. Ko ha ola nekativi hoʻo IGRA ʻoku ʻuhingá ngalingali naʻe ʻikai ke ke fetuʻutaki mo e siemu TB.
Ko hoʻo neesí pe ko hoʻo toketā te ne fakamatala atu ʻa e olá pea ʻe toe fiemaʻu nai ha tesi pe faitoʻo lahiange.
