Ngwa Oge Thromboplastin nke A Na-arụ Ọrụ (APTT)

Nnwale APTT bụ ule nyocha a na-ejikarị eme ihe n'ụlọọgwụ iji gosipụta ọrụ coagulation nke sistemu coagulation endogenous. A na-eji ya achọpụta ntụpọ coagulation endogenous na ihe mgbochi ndị metụtara ya, yana inyocha ihe na-akpata nguzogide protein C. O nwere ọtụtụ ojiji n'ihe gbasara nyocha, nlekota ọgwụgwọ heparin, nchọpụta mbụ nke coagulation intravascular gbasaara (DIC), na nyocha tupu ịwa ahụ.

Mkpa ahụike:

APTT bụ ihe nlele ọrụ coagulation nke na-egosipụta ụzọ coagulation endogenous, ọkachasị ọrụ zuru oke nke ihe coagulation na ọkwa mbụ. A na-ejikarị ya enyocha ma chọpụta ntụpọ nke ihe coagulation na ụzọ endogenous, dị ka factor Ⅺ, Ⅷ, Ⅸ, enwere ike iji ya maka nyocha mbụ nke ọrịa ọbara ọgbụgba na nlekota ụlọ nyocha nke ọgwụgwọ heparin anticoagulation.
