APTT waveform

The hidden sepsis marker: aPTT waveform analysis.

Thromb Haemost 2008; 100: 9–10 Downey et al. published a paper in 1997 entitled ‘Novel and diagnostically applicable information from optical waveform analysis of blood coagulation in disseminated intravascular coagulation’ (1). Using a new automated coagulation analyzer, the MDA-180, the authors observed that during measurement of the aPTT, some samples became turbid immediately after addition...

DIC Score: Statistical Relationship with PT, APTT, and Simplified Scoring Systems with Combinations of PT and APTT

We looked into the statistical association of prothrombin time (PT) and activated partial thromboplastin time (APTT) with disseminated intravascular coagulation (DIC) score calculated using the International society for thrombosis and haemostasis (ISTH) scoring system. The PT, APTT, PT + APTT, and PT/APTT ratios were evaluated against the DIC score by linear regression analysis in fifty inpatie...

Determination of APTT factor sensitivity – the misguiding guideline

INTRODUCTION The Clinical and Laboratory Standards Institute (CLSI) has produced a guideline detailing how to determine the activated partial thromboplastin time's (APTT) sensitivity to clotting factor deficiencies, by mixing normal and deficient plasmas. Using the guideline, we determined the factor sensitivity of two APTT reagents. METHODS APTTs were performed using Actin FS and Actin FSL o...
