Background Antiphospholipid syndrome (APS) is an acquired thrombophilia that can be associated with decreased platelet counts. Case A 67-year-old woman presented with thrombocytopenia and a symptomatic right atrial mass suspicious of cardiac myxoma. Prolongation of the activated partial thromboplastin time (aPTT) was caused by a strong lupus anticoagulant, and bone marrow cytology was consisten...

A wide variety of animal models on thrombosis and hemostasis are used in research for the preclinical assessment hemostatic agents. While vertebrate coagulome is highly conserved, human plasmas differ considerably when evaluated coagulation assays such as prothrombin time (PT), activated partial thromboplastin (APTT), calibrated automated thrombography (CAT). Here, we have aimed to provide a re...

Background: A COVID 19 vaccine is a intended to provide acquired immunity against severe acute respiratory syndrome corona virus 2. Ad26.COV2.S (Johnson & Johnson) adenovirus vector-based that targets the spike protein of SARS-CoV-2 virus, when it enters body stimulates immune response. Materials and methods: This was cross sectional study, health facility base, Conducted in Vacci...

INTRODUCTION Prothrombin time (PT) and activated partial thromboplastin time (APTT) sensitivity for detecting isolated factor deficiencies varies with different reagents and coagulometers. The Clinical and Laboratory Standards Institute (CLSI) H47A2 guideline proposed a method to calculate these sensitivities, but some inconsistency has been reported. This study aimed to calculate factor sensit...
