First, we encountered difficulty obtaining the aPTT reagent used at the time ... Since our laboratory had recently acquired a coagulation analyzer that had the ability to perform a rapid anti ...

aPTT, Fibrinogen and clotting factors. Automatic start when sample and reagent are mixed together in the cuvette. It has 37°C incubator with 18 samples capacity. PT data are printed with RATIO ...

This assay is readily available and inexpensive. However aPTT reagents are poorly standardized and have different sensitivities to heparin. There is no dose response relationship with heparin. Due to ...

Objective: To determine the frequency of discordant aPTT and anti-Xa values in a large cohort of hospitalized patients treated with UFH, as well as the demographics, coagulation status ...

Even so, there are other pre-analytical factors connected to coagulation ... 3000 tests, 40 reagents, and five additional buffer positions Approximately 180 simultaneous PT/APTT tests per hour ...

and in index of coagulation (p=0.036) in agreement to the type of reagent. Difference not exist (p>0.05) between boys and girls, or by surgical and clinical conditions. Conclusions ...
