Abstract:
Objective To investigate the plasma separation after samples to laboratory under different centrifugal conditions of b-type natriuretic peptide (BNP)the influence of the test results.Methods Randomly selected 20 cases of hospitalized patients at our hospital,the vacuum EDTA-K2 anticoagulant blood,respectively from several different centrifugal speed and time after centrif-ugal separation of plasma,the Siemens ADVIA Centaur CP on automatic chemiluminescence meter yet.Results Based on the same patients at the same time of blood specimens,under different centrifugal conditions and preparation of plasma BNP results meas-ured by comparative analysis,the centrifugal rotational speed of 3 000 r/min,the centrifugal time reach more than 5 min for the plasma specimens centrifugal conditions required by the test results and the kit standard preparation of plasma determination results difference has no statistical significance (P >0.05).Conclusion As soon as possible in order to determine the BNP as a result,es-pecially emergency specimens at night,when the centrifugal rotational speed and time to meet the 3 000 r/min and 5 min,can ob-tain accurate detection results,for clinical results as soon as possible for the BNP,diagnosis heart failure to win the time.
