Comprehending clotting times is pivotal for assessing the coagulation process. Prothrombin time (PT) and activated partial thromboplastin time (aPTT) serve as prevalent measures, examining the extrinsic and common pathways, and intrinsic and common pathways, respectively. These tests, conducted on plasma with activators like thromboplastin or factor XII activators, identify irregularities in coagulation factors. If PT or aPTT surpasses 120% of the normal range, it’s flagged as abnormal. The activated clotting time (ACT), a swift test, directly scrutinizes intrinsic and common pathways using diatomaceous earth as an activator. However, ACT might overlook deficiencies in prekallikrein, HMWK, or factors XII and XI. It’s intriguing how these tests offer a glimpse into the coagulation cascade, revealing potential issues in blood clotting factors.
