D-dimers: a most misunderstood test
British Journal of Hospital Medicine, 2021The role of D-dimers in the management of venous thromboembolism is well established and testing for D-dimers has become common in most acute settings. Although it has been validated for the purpose of excluding venous thromboembolism, the test is increasingly ordered to ‘diagnose’ venous thromboembolism.

Tensor products of D-posets and D-test spaces
Reports on Mathematical Physics, 1994A \(D\)-poset (or a difference poset) is a poset \(L\) with the greatest element 1 and a partial binary operation \(\ominus: L\times L\to L\) such that \(b\ominus a\) is defined iff \(a\leq b\) and, for \(a,b, c\in L\), we have (i) \(b\ominus a\leq b\); (ii) \((b\ominus (b\ominus a))=a\); (iii) if \(a\leq b\leq c\), then \(c\ominus b\leq c\ominus a ...

Advances in clinical chemistry, 2023
D-dimer containing species are soluble fibrin degradation products derived from plasmin-mediated degradation of cross-linked fibrin, i.e., 'D-dimer'. D-dimer can hence be considered a biomarker of in vivo activation of both coagulation and fibrinolysis, the leading clinical application in daily practice of which is ruling out venous thromboembolism ...

Testing of D/A and A/D converters
1994To verify the different specifications of converters and converter systems it is important to set up test facilities and structures and to agree unanimously on the test procedures. In general, static performance tests can be performed by using digital voltmeters which can be a part of an Automatic Test Equipment set (ATE).

Digestive Diseases and Sciences, 1991
The D-xylose absorption test has been used during the last four decades for evaluation of malabsorption in the small intestine. However, some disagreement still exists about the recommended method of performing this test: the 1-hr blood test, the 5-hr urine test, or both.

TREIMAN-YANG TEST FOR D+D→D+P+N
1972Publisher Summary This chapter discusses the Treiman–Yang test (TY-test) for d+d→d+p+n. Experimental few-nucleon studies on deuteron breakup reactions have unambiguously shown that apart from local enhancements because of the final-state interactions (FSI), the differential cross -section is largely characterized by quasi-free scattering (QFS ...

Emergency department D-dimer testing
The Journal of Emergency Medicine, 2001Since the early 1980s, much attention has been paid to the development of a biochemical marker for venous thromboembolism. D-dimers are derivatives of fibrinolysis and recently have been touted as a means of screening for thromboemoblism. We review the physiologic, pathologic, and chemical bases for this new test, and outline the specific D-dimer ...

The rise and rise of vitamin D testing
BMJ, 2012Moynihan and colleagues’ report highlights the increasing trend for overdiagnosis, particularly of endocrine disorders.1 Similar concerns exist for overdiagnosis and overtreatment of vitamin D deficiency.2 3 Currently, the appropriate timing and frequency of testing for the diagnosis of vitamin D deficiency is unclear. The cost of testing in …

Comparator testing in a flash A/D converter
2009 IEEE International SOC Conference (SOCC), 2009In this paper, a method of testing a flash A/D converter is presented. The flash A/D is first reconfigured as a Propagation Type A/D and it is tested afterwards. It is shown that the testing method is suitable for a fully automated use i.e. without the need of external devices.

On \(d\)-optimality of the LR tests
Kybernetika, 1995Summary: The lower asymptotic distributional bound of the level attained is attained in the case of the likelihood ratio statistics. The regularity conditions on which the proofs are based are verified for the non-singular normal, the multinomial and the Poisson distribution.
