Ngati vuto la magazi layamba kugayika, mutha kupita kuchipatala kuti mukazindikire plasma prothrombin. Zinthu zenizeni zoyezera magazi ndi izi:

1. Kuzindikira prothrombin ya plasma: Kuchuluka kwabwinobwino kwa kuzindikira prothrombin ya plasma ndi masekondi 11-13. Ngati nthawi yothira magazi yapezeka kuti yatalikirapo, zimasonyeza kuwonongeka kwa chiwindi, matenda a chiwindi, matenda a chiwindi, matenda a chikasu chotsekeka ndi matenda ena; ngati nthawi yothira magazi yafupika, pakhoza kukhala matenda a thrombosis.

2. Chiŵerengero cha padziko lonse chowongolera: Ichi ndi chiŵerengero chowongolera pakati pa nthawi ya prothrombin ya wodwalayo ndi nthawi ya prothrombin yachibadwa. Chiwerengero cha nambalayi ndi 0.9 ~ 1.1. Ngati pali kusiyana ndi mtengo wachibadwa, zimasonyeza kuti ntchito yotsekeka yaonekera. Pamene kusiyana kwakukulu, vuto limakula kwambiri.

3. Kuzindikira nthawi yogwira ntchito ya thromboplastin: Iyi ndi njira yoyesera yodziwira zinthu zozungulira zomwe zimapangitsa kuti magazi azitsekeka. Mtengo wabwinobwino ndi masekondi 24 mpaka 36. Ngati nthawi yozungulira ya wodwalayo yatalikitsidwa, zimasonyeza kuti wodwalayo akhoza kukhala ndi vuto la kusowa kwa fibrinogen. Amakhala ndi matenda a chiwindi, matenda a jaundice obstructive ndi matenda ena, ndipo makanda obadwa kumene angavutike ndi kutuluka magazi; ngati ndi yochepa kuposa yachibadwa, zimasonyeza kuti wodwalayo akhoza kukhala ndi matenda a mtima, sitiroko ya ischemic, venous thrombosis ndi matenda ena.

4. Kuzindikira fibrinogen: kuchuluka kwabwinobwino kwa mtengo uwu kuli pakati pa 2 ndi 4. Ngati fibrinogen ikukwera, zimasonyeza kuti wodwalayo ali ndi matenda opatsirana kwambiri ndipo akhoza kudwala matenda a atherosclerosis, matenda a shuga, uremia ndi matenda ena; Ngati mtengo uwu watsika, pakhoza kukhala matenda a chiwindi oopsa, matenda a chiwindi ndi matenda ena.

5. Kudziwa nthawi ya thrombin; nthawi yachibadwa ya mtengo uwu ndi 16-18, bola ngati ndi yayitali kuposa nthawi yachibadwa ndi kupitirira 3, si zachilendo, zomwe nthawi zambiri zimasonyeza matenda a chiwindi, matenda a impso ndi matenda ena. Ngati nthawi ya thrombin yafupikitsidwa, pakhoza kukhala ma calcium ions m'magazi.

6. Kuzindikira D dimer: Chiwerengero cha nthawi zonse cha mtengo uwu ndi 0.1 ~ 0.5. Ngati mtengowo wapezeka kuti wawonjezeka kwambiri panthawi yoyezetsa, pakhoza kukhala matenda a mtima ndi mitsempha yamagazi, pulmonary embolism, ndi zotupa zoyipa.
