Ko te wā thrombin (TT) me te wā prothrombin (PT) e whakamahia whānuitia ana hei tohu i te mahi toto toto tiketike, ko te rerekētanga i waenga i ngā mea e rua kei te kitea ngā momo āhuatanga toto toto tiketike.

Ko te wā thrombin (TT) he tohu mō te wā e hiahiatia ana hei kite i te huringa o te prothrombin plasma ki te thrombin. Ko te nuinga o te wā e whakamahia ana hei aromatawai i te āhua o te mahi a te fibrinogen me ngā āhuatanga coagulation I, II, V, VIII, X me XIII i roto i te plasma. I te wā o te tukanga kimi, ka tāpirihia he nui o te prothrombin kiko me ngā katote konupūmā hei huri i te prothrombin i roto i te plasma ki te thrombin, ā, ka inehia te wā huringa, koinei te uara TT.

Ko te wā Prothrombin (PT) he taupū hei kite i te mahi a ngā take toto totoka i waho o te pūnaha toto totoka. I te wā o te tukanga kimi, ka tāpirihia he nui o te hanganga take totoka (pērā i ngā take totoka II, V, VII, X me te fibrinogen) hei whakahohe i te pūnaha totoka, ā, ka inehia te wā mō te hanganga toto totoka, koinei te uara PT. Ko te uara PT e whakaata ana i te āhua o te mahi take totoka i waho o te pūnaha totoka.

Me mōhio ko ngā uara TT me PT he tohu e whakamahia whānuitia ana hei ine i te mahi toto totoka, engari kāore e taea e rāua te whakakapi tetahi i tetahi, ā, me whiriwhiri ngā tohu kitenga tika kia rite ki te āhua motuhake. I taua wā anō, me mōhio ko ngā rerekētanga o ngā tikanga kitenga me ngā matū ka pā ki te tika o ngā hua, ā, me aro nui ki ngā mahi paerewa i roto i te mahi haumanu.
