The validity of the postcoital test
American Journal of Obstetrics and Gynecology, 1990Opinion is divided on the clinical usefulness of the postcoital (Sims-Huhner) test in diagnosing infertility. To evaluate the validity of this test, we reviewed the world's literature in English and calculated four indexes of validity for each study with sufficient information. The sensitivity of the test ranged from 0.09 to 0.71, specificity from 0.62

The Validity of the Atropine Test
Gynecologic Investigation, 2010In order to evaluate the clinical validity of the so-called ‘atropine test’, it has been performed in 83 women in their 35th to 43rd week of pregnancy. A statistical evaluation of the data has shown a serious limitation of both diagnostic and prognostic possibilities of the test; this can be attributed to the great variability of maternal environments.

Assessment, 2008
Common rates employed in classificatory testing are the true positive rate (TPR), false positive rate (FPR), positive predictive power (PPP), and negative predictive power (NPP). FPR and TPR are estimated from research samples representing populations to be distinguished by classificatory testing.

Tests may provide valuable information for identification or prediction functions. Examples include disease diagnosis and staging, therapeutic outcome prediction, outbreak detection, infection control policy compliance monitoring, and other quality assurance monitoring.

ON THE VALIDITY OF THE RORSCHACH TEST
Scandinavian Journal of Psychology, 1965Rorschach protocols of 20 persons (normals, depressives, and schizophrenics) were analysed, using the inverted, or Q, method of factoring. Three factors emerged from the analysis and corresponded to the three psychiatric categories. Groups of items, allegedly measuring the isolated factors, were applied to a second population of 42 persons resulting in

Abstract This paper proposes a method to determine whether or not the real plant model is in a domain which is defined with a given nominal plant model and a given perturbation bound, when an input sequence and an output sequence of the plant are available.

Validity Testing of the accuPINCH THC Test
Journal of Analytical Toxicology, 1995Self-contained drug-testing kits are currently being marketed for a variety of drugs of abuse. These tests are designed to provide rapid access to test results without the need for laboratory facilities. This report describes a validity study of the accuPINCH THC test, a self-contained test for cannabinoids in urine.

The Validity of a Screening Test
Optometry and Vision Science, 1982Abstract Many health professionals screen for the early detection of disease. Unfortunately, many of the tests and programs have poor validity or are applied to screening populations where the prevalence of disease precludes efficient screening operations.

Drug Metabolism Reviews, 1990
In summary, the extent of toxicity studies which can be carried out with bound residues of nitroimidazole drugs will be dictated by the availability and the amount of residues that can be produced. For evaluating their toxicity the use of the Salmonella assay, which has been proven to be sensitive for the parent drugs, is proposed.
