Ibiranga imikorere
Imipaka ntarengwa: PG I≤2.0 ng / mL, PG II≤ 1.0 ng / mL;
Urwego:
PG I: 2.0-200.0 ng / mL, PG II: 1.0-100.0 ng / mL ；
Coefficente ihuza umurongo R ≥ 0,990;
Icyitonderwa: mugice cya CV ni ≤ 15%;hagati yicyiciro CV ni ≤ 20%;
Ukuri: gutandukana kugereranya ibisubizo byo gupima ntibishobora kurenga ±15% mugihe igeragezwa ryukuri risuzumwa.
1. Bika buffer ya detector kuri 2 ～ 30 ℃.Buffer ihagaze neza kugeza kumezi 18.
2. Ubike Aehealth Ferritin Rapid Quantitative test cassette kuri 2 ～ 30 ℃, ubuzima bwigihe kigera kumezi 18.
3. Cassette yikizamini igomba gukoreshwa mugihe cyisaha 1 nyuma yo gufungura paki.
Pepsinogen ni protease prursor isohoka na mucosa gastrica kandi irashobora kugabanywamo ubwoko bubiri: PG I na PG II.PG I isohorwa na selile nkuru ya glande ya fundus na selile cervical mucus selile, naho PG II isohorwa na glande ya fundus, glande pyloric, na glande ya Brunner.Hafi ya synthesize ya PG yinjira mu mwobo wa gastric kandi igakorwa kuri pepsin munsi ya acide gastric.Mubisanzwe, hafi 1% ya PG irashobora kwinjira mumaraso binyuze mumitsi ya gastrica, kandi kwibumbira hamwe kwa PG mumaraso byerekana urwego rwururenda.PG I ni ikimenyetso cyerekana imikorere ya gastric oxyntic gland selile.Kwiyongera kwa acide gastricike byongera PG I, bigabanya gusohora cyangwa kugabanya gastric mucosal gland atrophy;PG II ifite isano nini na gastric fundus mucosal lesions (ugereranije na mucosa gastral antral mucosa).Hejuru ifitanye isano na fundus gland atrophy, gastric epithelial metaplasia cyangwa pseudopyloric gland metaplasia, na dysplasia;mugikorwa cya fundus gland mucosal atrophy, umubare wutugingo ngengabuzima dusohora PG I uragabanuka kandi umubare wa selile pyloric gland wiyongera, bigatuma PG I I / PG II igabanuka.Kubwibyo, igipimo cya PG I / PG II kirashobora gukoreshwa nkikimenyetso cyerekana gastric fundic fundic gland mucosal atrophy.
