PTT (partial thromboplastin time) is prolonged due to abnormalities of the intrinsic pathway. When both the PT and PTT are prolonged, blood takes longer to clot and the bleeding risk increases.Blood Test for Clotting Disorders The ability of human blood to form clots prevents someone from ...

在PTT试验中,两种血凝仪得到了相似的结果。在进行平均凝固 时间基数较小的PT试验时,两种不同原理的血凝仪得到的结果具有较高的符合率。根据研究的结果,选择双磁路磁 珠法或散射比浊法血凝仪来进行医疗器械凝血相关评价均为可行,检验机构可根据自身条件灵活选择,但须注意对基 值较小的试验,如PT试验的结果解释和...

在PTT前再加actived,意思是测量时除了要加入部分凝血活酶,还需要加入活化接触因子激活剂(带负电荷),如白陶土、硅藻土等。 Thromboplastin is the combination of both phospholipids and tissue factor, both needed in the activation of theextrinsic pathway. However, partial thromboplastin is just phospholipids, ...
