In fact, aPTT is in normal range in contrast to other factor deficiencies. Different aPTT reagents and methods of determination are in use in various laboratories. Therefore, a wide variation in results will be obtained when aPTT is measured in Fletcher factor deficient plasmas. These circumstances...
Objective: To investigate the correlation of fibrinogen level and absorbance change in both PT and APTT clotting curves on BCSXP Analyzer. Methods:A serial of standard fibrinogen and 250 patient plasma samples with different qualities(normal, hemolysis, icterus, and lipemia) were run on BCSXP for...
The recommended aPTT goal is set at 1.5–2.5 times the patient’s normal baseline. However, this goal arises from a study conducted more than half a century ago, reporting on a decreased incidence of recurrent venous thromboembolism [15]. This range was never validated in controlled randomized ...
The usual therapeutic range for the lab-APTT ratio is 1.5–2.5, as defined by Basu et al. in 1972 [5]. This therapeutic range was previously confirmed for C.K. Prest®[13]. We divided the lab-APTT ratio into low (1.5–2.0) and high (2.0–2.5) therapeutic ranges according to the...
