A Reason for Rejection or a Clinical Challenge? Paolo Carraro, Giuseppe Servidio, Mario Plebani. Published February 2000 Hemolyzed Specimens: A Reason for Rejection or hemolyzed coagulation test results

Test Resources; Blood Specimens: Coagulation; Blood Specimens: Coagulation Severely hemolyzed samples are not acceptable. 5. Underfilling of citrate collection tubes results in an increased anticoagulanttoblood ratio and can extend clotbased coagulation assays.

Hemolyzed specimens are rejected for coagulation testing based on concerns of artifactual interference. Prothrombin time ( PT ), activated partial thromboplastin time ( PTT ), and selected factor assay test results for consecutive pairs of hemolyzed and subsequently recollected (mean, 72 minutes later) nonhemolyzed patient specimens were compared. May 03, 2017 Preanalytics For Coagulation Testing: Pitfalls And Possible Impact. France, 3 May 2017. Preanalytics is crucial for clinical laboratory test results. Preanalytics covers all steps between laboratory test order and sample analysis. Most errors occur during this key step. (mechanical detection) in paired hemolyzed versus nonhemolyzedhemolyzed coagulation test results From Cristina: What is the reason why lipemic and hemolyzed coagulation sample should be rejected? Is it only the Ddimer is susceptible? Thanks. Hello, and thank you for your question. Lipemia is likely to cloud the final reaction solution in a photooptical method, interfering with the results.

that test results on spuriously hemolyzed specimens should be systematically sup and test results will either be unreliable or not implemented in coagulation instrumentation (e. g. , the so hemolyzed coagulation test results Samples with slight hemolysis are analyzed and the results reported with a comment indicating the degree of hemolysis and the effect on the test result. Grossly hemolyzed samples can affect the results of many tests; therefore, a recollection will be requested for most grossly hemolyzed samples. The consequence of hemolyzed blood sample rejection is repeat blood sample collection that causes additional discomfort to patients, delayed test results, and increased laboratory operating costs. [7 What Is Hemolysis, and How Does It Affect Lab Results? Hemolysis, or the breakdown of red blood cells, affects laboratory tests in varying degrees and is dependent on the test being performed, according to Calgary Lab Services. Jan 11, 2006 Hemolyzed specimens are rejected for coagulation testing based on concerns of artifactual interference. Prothrombin time (PT), activated partial thromboplastin time (aPTT), and selected factor assay test results for consecutive pairs of hemolyzed and subsequently recollected (mean, 72 minutes later) nonhemolyzed patient specimens were compared.
