La variabilità preanalitica in coagulazione
Pre-analytical issues in coagulation testing
<p>Poor standardization of preanalytic variables influences greatly thereliability of coagulation testing, consuming health care resources and compromising patient outcomes. Thesevariables include patient preparation, sample collection, handling, transportation, processing, and storage until timeof analysis: lack of standardized procedures for sample collection accounts for most of the errors encountered withinthe total testing process. Most pre-analytical problems may arise from system faults and insufficient audit of theoperators involved in specimen collection and handling, leading to unsuitable specimens due to misidentification,hemolysis, clotting, inappropriate volume, wrong container, contamination from the infusive route. Detection,acknowledgement and management of pre-analytical variables, is mandatory for delivering accurate laboratoryresults. The present document, issued by the Study Group on Haemostasis of the Italian Society of LaboratoryMedicine, is a summary of the recommendations for standardisation of the pre-analytical phase of the coagulationtesting, related to sample collection, transportation, and storage and provides guidance to reduce the effects of pre-analytical issues that can have a significant impact on patient care.</p>

Presenza concomitante di anticorpi tipo Lupus e malattia di von Willebrand: una condizione reale?
Combined von Willebrand factor and lupus anticoagulant abnormalities: a true finding?
<p>We present a case of a 74-year-old woman with myelofibrosis, hypothyroidism and negative bleeding history, showing a prolonged APTT performed within a pre-intervention screening. The laboratory tests showed a positivity for the presence of lupus anticoagulant antibodies (LA). Further investigations revealed normal intrinsic factor and von Willebrand factor (VWF) antigen concentrations, and normal to only slightly reduced VWF Ristocetin Cofactor (VWF:RCo) by chemiluminescent assay and by platelet agglutination. The VWF:RCo by a latex- immunoturbidimetric method was strongly reduced and the platelet function test was found to be abnormal. The negative bleeding history, the myeloproliferative chronic disease, the LA positivity and the other laboratory findings were consistent with the presence of acquired VWF disease. However, the disproportionate values of VWF:RCo measurements obtained by the latex method and all the other assays, made us to conclude for the presence of an interference (possibly due to autoantibodies) on latex VWF:RCo immunoassay and the patient went successfully to surgery without anti-haemorrhagic prophylaxis.</p>
