The Nonstress Test: Reassessment of the “Gold Standard”
Clinics in Perinatology, 1994The NST is simpler, less invasive, less time-consuming, and less expensive than its predecessor, the CST. It may be conducted in the outpatient setting with less skilled personnel. If the NST is to remain an important diagnostic modality, the issues of interpretative criteria, test conditions, and population composition must be reconsidered.

Evaluation of diagnostic tests without gold standards
Statistical Methods in Medical Research, 1998This paper reviews statistical methods developed to estimate the sensitivity and specificity of screening or diagnostic tests when the fallible tests are not evaluated against a gold standard. It gives a brief summary of the earlier historical developments and focuses on the more recent methods.

Immunofluorscense - still the 'gold standard' in ANA testing?
Scandinavian Journal of Clinical and Laboratory Investigation, 2001A usefulness of enzyme immunoassay (EIA)-based antinuclear antibodies (ANA) tests was evaluated in comparison with the immunofluorescence ANA assay (IF-ANA). COBAS-ANA and MBL-ANA were used, in the former a mixture of antigens extracted from HEp-2 cells and multiple recombinant antigens was immobilized on beads as the antigen, and in the latter 9 kinds

The choice of gold standard for evaluating tests for caries diagnosis.
Dentomaxillofacial Radiology, 1999All research is intended to provide new information. Studies should be designed in such a way that their results can be generalised to either a population or a process. Researchers function within a common paradigm, first described by Kuhn. 1 A paradigm is a framework containing patterns of thought which are ‘commonly agreed upon’ within a certain ...

Randomization tests: A new gold standard?
Journal of Contextual Behavioral Science, 2014Abstract Classical statistical methods rely on the analytical power of mathematics and some assumptions rather than on computer power. In research with human participants the assumption of random sampling is rarely correct. The great increase in computer power in recent decades makes available an approach to statistical inference which does not ...

This entry describes the concept of an error-free diagnostic test, and the practical difficulties of attainting this ideal. The consequences of assuming a test to be error-free when in fact it is not are also mentioned.

Identifiability of Models for Multiple Diagnostic Testing in the Absence of a Gold Standard
Biometrics, 2009Summary We discuss the issue of identifiability of models for multiple dichotomous diagnostic tests in the absence of a gold standard (GS) test. Data arise as multinomial or product‐multinomial counts depending upon the number of populations sampled. Models are generally posited in terms of population prevalences, test sensitivities and specificities ...

“TAGS”, a program for the evaluation of test accuracy in the absence of a gold standard
Preventive Veterinary Medicine, 2002When a perfect reference test (i.e. "gold standard") is not available, it is possible to obtain estimates of test sensitivity and specificity using "latent-class" methods. However, there are few widely available software programs that allow implementation of these procedures.
