The partial thromboplastin time (PTT), also known as the activated partial thromboplastin time (aPTT or APTT), is a blood test that characterizes coagulation of the blood. A historical name for this measure is the Kaolin-cephalin clotting time ( KCCT ), [ 1 ] reflecting kaolin and cephalin as materials historically used in the test.
Guidelines on the choice of agents and how best to step up treatment for various subgroups in hypertension (high blood pressure) have changed over time and differ between countries. A Comparison of International Guidelines on Goal Blood Pressure and Initial Therapy for Adults With Hypertension (adapted from JNC 8 guidelines [ 1 ] )
Guidelines for treating resistant hypertension have been published in the UK [45] and US. [46] It has been proposed that a proportion of resistant hypertension may be the result of chronic high activity of the autonomic nervous system, known as "neurogenic hypertension". [47] Low adherence to treatment is an important cause of resistant ...
These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin, bilirubin (direct and indirect), and others. The liver transaminases aspartate transaminase (AST or SGOT) and alanine transaminase (ALT or SGPT) are useful biomarkers of liver injury in a patient with some degree of intact liver function.
The ISTH guidelines suggested diagnostic and early management strategy. [36] Suggestions included 1) for high pretest probability based on PLASMIC score or French score, start TPE and corticosteroids, and collect plasma samples for ADAMTS13 testing before therapy. Consider caplacizumab if ADAMTS13 test results are expected within 72 hours.

A North Carolina father is facing criminal charges after authorities allege he left his child isolated in a room with a space heater for more than 12 hours, leading to his death.
The aPTT-based APC resistance test involves a modified aPTT test performed in the presence and absence of activated protein C (APC). [1] [5] The ratio of these aPTT values is calculated and is called the APC sensitivity ratio (APCsr) or simply APC ratio (APCr). [1] [5] This ratio is inversely related to the degree of APC resistance. [7]
