Abstract:
Objective To investigate clinical application of critical value of platelet count and its threshold adjustment . Methods Theincidence rate and regularities of distribution of critical value of platelet count were retrospectively analyzed in pa‐tients ,whose platelet count was ≤50 × 109/L from Jan .2012 to Dec .2013 .And the suitable critical values of platelet count for dif‐ferent clinic units were set through clinical coordination .Results The platelet count were detected in 193 776 samples ,and detection results of 1 602 samples reached the critical value of platelet count (detection rate was 0 .83% ) .The critical value of platelet for he‐matology unit was adjusted to ≤10 × 109/L ,for surgical unit was adjusted to ≤50 × 109/L ,and for other units the critical value was still ≤20 × 109/L .Meanwhile ,cases were regarded as reaching the critical value when detection results of platelet count were differ by 50% in short time .Conclusion The adjustment of critical value of platelet count for different units could improve efficiency of clinic and laboratory ,and enhance safety of patients .
