Iimpawu zoMsebenzi
Umda wokufumanisa: PG I≤2.0 ng/mL, PG II≤ 1.0 ng/mL;
Uluhlu lomgca:
PG I: 2.0-200.0 ng/mL, PG II: 1.0-100.0 ng/mL;
I-coefficient yokulungelelanisa yomgca R ≥ 0.990;
Ukuchaneka: ngaphakathi kwe-batch CV ngu ≤ 15%;phakathi kweebhetshi iCV yi ≤ 20%;
Ukuchaneka: ukutenxa okunxulumene neziphumo zomlinganiselo akusayi kudlula ±I-15% xa kuvavanywa isilinganisi sokuchaneka esisemgangathweni.
1. Gcina i-detector buffer ku-2～30℃.Isithinteli sizinzile ukuya kwiinyanga ezili-18.
2. Gcina i-Aehealth Ferritin Rapid Quantitative test cassette kwi-2～30℃, ubomi beshelufu bufikelela kwiinyanga ezili-18.
3. Ikhasethi yovavanyo kufuneka isetyenziswe kwiyure enye emva kokuvula ipakethi.
I-Pepsinogen yi-protease precursor efihliweyo yi-gastric mucosa kwaye inokwahlulwa ibe yi-subtypes ezimbini: i-PG I kunye ne-PG II.I-PG I ikhutshwa ziiseli eziphambili ze-fundus glands kunye ne-cervical mucus cells, kwaye i-PG II ikhutshwe ngamadlala e-fundus, amadlala e-pyloric, kunye namadlala e-Brunner.Uninzi lwe-PG edibeneyo ingena kwi-gastric cavity kwaye isebenze kwi-pepsin phantsi kwesenzo se-asidi yesisu.Ngokuqhelekileyo, malunga ne-1% ye-PG inokungena kwi-blood circulation nge-gastric mucosa, kwaye ukuxinwa kwe-PG egazini kubonisa inqanaba layo lokukhupha.I-PG I sisalathisi somsebenzi weeseli zegastric oxyntic gland.Ukunyuka kwe-gastric acid secretion kwandisa i-PG I, kunciphisa ukukhupha okanye kunciphisa i-atrophy ye-gastric mucosal gland;I-PG II inonxulumano olukhulu kunye nezilonda ze-gastric fundus mucosal (xa kuthelekiswa ne-gastric antral mucosa).Uphakamileyo unxulumene ne-fundus gland atrophy, i-gastric epithelial metaplasia okanye i-pseudopyloric gland metaplasia, kunye ne-dysplasia;kwinkqubo ye-fundus gland mucosal atrophy, inani leeseli eziphambili ezikhupha i-PG I liyancipha kwaye inani leeseli ze-pyloric gland liyenyuka, okukhokelela kwi-PG I / PG II ratio yehla.Ke ngoko, umlinganiselo wePG I/PG II ungasetyenziswa njengesalathiso se-gastric fundic gland mucosal atrophy.
