Pitfalls in Coagulation Testing

Hämostaseologie, 2023
AbstractAssays in the coagulation laboratory are affected by numerous variables. Variables which have impact on the test result can lead to incorrect results, and potentially to consequences for further diagnostic and therapeutic decisions made by the clinician.

Quality Control in Coagulation Testing

Seminars in Thrombosis and Hemostasis, 2008
The term "QUALITY CONTROL" in laboratory medicine refers to all the procedures commonly used in clinical laboratories to monitor the routine performance of testing processes, to detect possible errors, and to correct problems before test results are reported.

Blood Coagulation and Coagulation Tests

Medical Clinics of North America, 1984
The hemostatic mechanism has evolved to provide efficient protection from traumatic blood loss and yet maintain the blood in a fluid state in the circulation as a whole. Recent advances in biochemistry have provided both detailed understanding of hemostasis and clinically useful coagulation assays to exploit this understanding.

Ultracentrifugation for Coagulation Testing

2023
Lipemia is known to potentially affect coagulation testing. It may be detected with newer coagulation analyzers that are validated to assess hemolysis, icterus, and lipemia (HIL) in a plasma sample. In samples with lipemia where accuracy of the test result is compromised, strategies for mitigating the lipemia interferences would be required.

Evolution of viscoelastic coagulation testing

Expert Review of Hematology, 2020
The methods of viscoelastic coagulation testing (VCT) have evolved since the original invention of thrombelastography over 60 years ago, and new generations of devices are clinically used to guide hemostatic interventions at bedside. The utility of VCTs has been demonstrated in several clinical trials, but diagnostic performance of VCT may vary between

Reference Ranges of Coagulation Tests

2013
Reference ranges are a set of values that correctly include most of the subjects with characteristics similar to the reference group and exclude the others. When accurate, reference ranges aid physicians to interpret results of clinical measurements and thus establish diagnosis. However, obtaining accurate reference ranges is a very demanding procedure.

Acquired coagulation disorders: revisited using global coagulation/anticoagulation testing

British Journal of Haematology, 2009
SummaryAcquired coagulation defects are characterized by a decrease of both pro‐ and anti‐coagulants. Because of this, we hypothesise that global tests, such as the prothrombin and partial thromboplastin times (PT and APTT), might be unsuitable for their investigation.

Blood Coagulation Tests of Gorillas

Journal of Medical Primatology, 1982
In coagulation tests on five lowland gorillas, values within or close to the normal human range were found with the following tests: partial thromboplastin time, prothrombin time, thrombin time, factor XIII screen, factor II assay, factor V assay, fibrinogen and antithrombin III. Factor XII levels were very high.

Laboratory coagulation tests

2018
POCT systems are able to measure the different phases of hemostasis (primary hemostasis, thrombin/fibrin formation, clotting and fibrinolysis). The measurements record complex biological processes. These analytical systems mostly demand a high level of training, interpretative competence and quality assurance.
