PT imatanthauza nthawi ya prothrombin mu mankhwala, ndipo APTT imatanthauza nthawi yogwira ntchito ya thromboplastin yochepa mu mankhwala. Ntchito yogwira ntchito ya magazi m'thupi la munthu ndi yofunika kwambiri. Ngati ntchito yogwira ntchito ya magazi si yachilendo, ingayambitse thrombosis kapena kutuluka magazi, zomwe zingaike moyo wa wodwalayo pachiwopsezo chachikulu. Kuyang'anira PT ndi APTT kuchipatala kungagwiritsidwe ntchito ngati muyezo wogwiritsira ntchito mankhwala ena oletsa magazi m'machitidwe azachipatala. Ngati miyezo yoyezedwayo ndi yokwera kwambiri, zikutanthauza kuti mlingo wa mankhwala oletsa magazi uyenera kuchepetsedwa, apo ayi kutuluka magazi kungachitike mosavuta.

1. Nthawi ya Prothrombin (PT): Ndi chimodzi mwa zizindikiro zodziwika bwino za dongosolo la magazi a anthu. Ndikofunikira kwambiri kutalikitsa nthawiyo kwa masekondi opitilira atatu mu ntchito zachipatala, zomwe zingawonetse ngati ntchito ya exogenous coagulation ndi yachibadwa. Kutalikitsa nthawi nthawi zambiri kumawoneka mu congenital coagulation deficiency Factor, cirrhosis yayikulu, kulephera kwa chiwindi ndi matenda ena. Kuphatikiza apo, kuchuluka kwa heparin ndi warfarin kungayambitsenso PT yayitali;

2. Nthawi yogwira ntchito ya thromboplastin (APTT): Ndi chizindikiro chomwe chikuwonetsa ntchito ya magazi oundana m'thupi. Kutalikitsa kwakukulu kwa APTT kumawonekera makamaka mu kusowa kwa coagulation factor, monga hemophilia ndi systemic lupus erythematosus. Ngati mlingo wa mankhwala oletsa magazi oundana omwe amagwiritsidwa ntchito chifukwa cha thrombosis ndi wosazolowereka, ungayambitsenso APTT kutalikitsa kwakukulu. Ngati mtengo woyezedwa ndi wotsika, ganizirani kuti wodwalayo ali mu mkhalidwe woti magazi oundana kwambiri, monga thrombosis ya mitsempha yakuya.

Ngati mukufuna kudziwa ngati PT ndi APTT yanu ndi yabwinobwino, muyenera kufotokozera bwino za nthawi yawo yabwinobwino. Nthawi yabwinobwino ya PT ndi masekondi 11-14, ndipo nthawi yabwinobwino ya APTT ndi masekondi 27-45. Kutalikitsa PT kwa masekondi opitilira atatu kumakhala ndi tanthauzo lalikulu lachipatala, ndipo kutalikitsa APTT kwa masekondi opitilira 10 kumakhala ndi tanthauzo lalikulu lachipatala.
