Evaluación del tripolifosfato de sodio como anticoagulante en determinaciones hematológicas en seres humanos

the aim of present study was to assess the usefulness of anticoagulant sodium tripolyphosphate (tpp) in different hematologic determinations in human beings. venous blood samples from healthy adults of both sexes were anticoagulated with tpp, dipotassium salts of ethylenediaminetetra-acetic acid (edta) and sodium citrate. anticoagulated samples with edta and sodium citrate were used as controls. verifying the values achieved in all tests performed we noted that anticoagulated blood with tpp offered results similar to those treated with anticoagulant used as controls. results show that it is possible the use of tpp to determine the parameters of total hematology and coagulation times, allowing the use of only one sample with less blood volume, which could be beneficial for patients in which blood collection in significant volumes in occasions is difficult and annoying.
