Measurement of prothrombin time in EDTA plasma with combined thromboplastin reagent.
PCR product formation. During the dissociation protocol (slow cooling from 95 °C to 60 °C over a period of 20 min), the ABI 7700 instrument was also used in real time (every 3 s) to follow the melting profile of each sample. The correct melting peak for each sample was calculated by an appropriate algorithm as the first derivative at the flexus point (11 ). The flexibility of MTA allowed us to ...
متن کاملUse of EDTA samples for prothrombin time measurement in patients receiving oral anticoagulants.
BACKGROUND AND OBJECTIVES Oral anticoagulant therapy is commonly called for in health care. Hitherto sampling for prothrombin time (PT) has been measured on blood collected into a coagulation tube and diluted in citrate solution. Blood samples anticoagulated with EDTA are used for hematologic tests and the same sample could also be available for PT. DESIGN AND METHODS We studied 107 patients ...
متن کاملMeasurement of hemostatic factors in EDTA plasma.
This study determined whether immunoassays of factors VII (FVII) and VIII (FVIII) and von Willebrand factor (vWF) in EDTA-anticoagulated plasma samples are comparable to bioassays and immunoassays of these factors in citrate-anticoagulated plasma. Blood from 40 healthy volunteers was collected in EDTA- and citrate-anticoagulant tubes and assayed using immunoassays (EDTA and citrate) and clottin...
متن کاملColorimetric measurement of iron in plasma samples anticoagulated with EDTA.
AIMS To determine if the iron in EDTA anticoagulated plasma samples can be measured by colorimetric assays using Ferrozine. METHODS Paired samples of serum and EDTA plasma were obtained from 24 patients and analysed by three commercial iron methods. The EDTA plasmas were also analysed using methods modified by the addition of zinc sulphate or with different concentrations of Ferrozine. The ir...
متن کاملEffect of storage conditions on prothrombin time, activated partial thromboplastin time and fibrinogen concentration on canine plasma samples
The present study was to assess the effect of storage conditions on prothrombin time (PT), activated partial thromboplastin time (aPTT) and fibrinogen concentration in blood samples of healthy dogs. Thirty-five dogs of various breeds were included in the study. Citrated blood samples were obtained and plasma was divided into four aliquots to assess selected clotting parameters by means of a coa...
