Reference Ranges of Coagulation Tests
2013Reference 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.

Effects of Hemolysis on Routine Coagulation Tests when Tested on an Optical Coagulation Analyzer
Clinical Laboratory, 2023The Clinical and Laboratory Standards Institute recommends rejecting hemolyzed samples for coagulation tests. Sysmex CS5100 analyzer using an optical method is commonly used in laboratories. The influence of hemolysis on coagulation test has rarely been studied when tested on Sysmex CS5100.

An Algorithmic Approach to Coagulation Testing
Disease-a-Month, 2012he complexity of coagulation testing often makes the interpretation aunting. Basic knowledge of the coagulation cascade is not enough. nowledge of the test’s mechanistic features and functional limitations is equired. Although the acquisition of such knowledge is important, the linical scenario may not afford the luxury.

Evolution of viscoelastic coagulation testing
Expert Review of Hematology, 2020The 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

Tests of Coagulation in Liver Disease
Clinics in Liver Disease, 2009The complex coagulation defect secondary to chronic liver disease is considered responsible for the bleeding problems that often are associated with the disease. Accordingly, clinicians order laboratory tests to assess the risk of bleeding and rely on these results to make decisions about the management of the associated coagulation disturbances ...

Coagulation tests in differential diagnosis
Clinical & Laboratory Haematology, 2000Bleeding disorders pose a special problem for the practising physician haematologist or laboratory coagulation specialist. Great concern is placed on specimen integrity, either during handling or in storage. Heparin contamination, activated specimens and factor VIII lability are common issues.

Blood Coagulation Tests of Gorillas
Journal of Medical Primatology, 1982In 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.

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.

Publisher Summary This chapter discusses testing of coagulation factors. The tests involve the measurement of coagulation factors by methods that assess both their presence, as antigens and their ability to function or activity. Inherited coagulation factor deficiencies is of two types: type I defects (quantitative) have decreased absolute amounts of
