Lessons Learnt From Inappropriate D Dimer Testing Case Report We present the case of a patient wherein inappropriate d dimer testing led to inadequate anticoagulant therapy complicated with heparin induced thrombocytopenia, bleeding, and delayed diagnosis of acute leukemia. Introduction: since the beginning of the covid 19 pandemic, d dimer testing has been widely used in not yet approved indications. this has led to misdiagnosis, overuse of diagnostic procedures, and unnecessary costs.
D Dimer Testing In Clinical Practice Pdf Thrombosis Body Fluids While many tests are shown to be affected by interference from heterophilic antibodies, the d dimer test has rarely been reported to be affected. with this case, we report an elevated d dimer measurement which was not compatible with the clinical presentation. D dimer levels. three patients (0.3%) were diagnosed with pe, despite having normal d dimer levels. the researchers attempted to analyze the probability of thromboembolic disease at higher d dimer values and found that higher d dimer le. Introduction: d dimer tests were inappropriately over used in our emergency department as a result of bloods being taken before clinical assessment to help meet the ‘‘4 hour target’’. we introduced a multifaceted interven tion to reduce the number of inappropriate d dimer tests. Herein, we report a case with an extremely elevated level of d dimers but with no relevant symptoms related to thrombosis. we concluded that the d dimer test results were due to her cardiac factors and interference from her heterophilic antibodies against epstein barr virus (ebv).
Specific Pre Analytical Data Regarding D Dimer Testing Download Table Introduction: d dimer tests were inappropriately over used in our emergency department as a result of bloods being taken before clinical assessment to help meet the ‘‘4 hour target’’. we introduced a multifaceted interven tion to reduce the number of inappropriate d dimer tests. Herein, we report a case with an extremely elevated level of d dimers but with no relevant symptoms related to thrombosis. we concluded that the d dimer test results were due to her cardiac factors and interference from her heterophilic antibodies against epstein barr virus (ebv). Plasma d dimer is a screening marker for thrombosis and hemostasis disorders. falsely elevated d dimer may result in misdiagnosis and potentially invasive investigations. therefore, identifying falsely elevated d dimer is of great value in laboratory practice. In the search for a cost effective screening approach to pe, d dimer testing has advantages, often sparing patients unnecessary radiation and expense. however, d dimer has limitations, and it is imperative to understand these limitations in our practice. There is general perception that a d dimer test is the investigation of choice for the diagnosis of venous throm boembolism in any patient, without enough consideration having been given to their clinical situations and co morbidities. Our results identify interfering antibodies as a potential contributor to an increased d dimer in this patient. our case highlights the potential of heterophilic interference for increased d dimer and provides a procedure to determine this analytically.
