Predictive Value and Efficiency of Laboratory Testing

Pediatric Clinics of North America, 1980
Literature on determining reference values and reference intervals on "normal" or "healthy" individuals is abundant. It is impossible, however, to evaluate a data set of reference values and select a suitable reference interval that will be meaningful for the practice of medicine.

Normal tension glaucoma: The value of predictive tests

Acta Ophthalmologica, 1993
Abstract. Fifty‐four normal tension glaucoma cases were studied to determine the value of several clinical tests for predicting the progression of the disease. Outflow facility, intraocular pressure (IOP) increase after water drinking, and diurnal changes in IOP were studied.

Predictive value of the dexamethasone suppression test in mania

American Journal of Psychiatry, 1984
Eighteen manic patients who had abnormal results on the dexamethasone suppression test at admission were retested before discharge, when they were clinically stable. Conversion to normal suppression predicted good outcome after discharge, whereas a persistently abnormal test predicted poor outcome.

The Uncertainty Associated with the Predictive Value of Test Results

cclm, 1998
Abstract The uncertainty associated with predictive value of test results was taken into consideration, as concerns both sampling error (related to the size of the statistical reference samples) and analytical imprecision (unavoidably involved by the measurement itself). A software package, developed for the statistical calculations, was

Predictive Value of Serologic Tests for Syphilis in Otology

Annals of Otology, Rhinology & Laryngology, 1986
Otologic syphilis (luetic inner ear disease) usually is diagnosed by positive serologic tests and by exclusion of other possible causes. Because the FTA-ABS for syphilis is exquisitely sensitive in all but early primary cases, a positive FTA-ABS result and coincident inner ear disease often are thought to be diagnostic of syphilitic inner ear disease ...

Antiphospholipid Antibodies: Predictive Value of Laboratory Tests

Thrombosis and Haemostasis, 1997
aPL antibodies are a wide and heterogeneous family of autoantibodies, formerly believed to be directed at anionic phospholipids. In recent years they have been shown to be directed at plasma proteins bound to suitable (phospholipid) anionic surface: beta 2-GPI and prothrombin are the best known and characterized antigens, which are recognized by aCL ...

Predictive Value of an Adherence Test for Acute Otitis Media

Otolaryngology–Head and Neck Surgery, 1998
The predictive value of an in vitro adherence test of the bacterium Streptococcus pneumoniae for the development of recurrent otitis media was calculated 5 years after the initial test. Nasopharyngeal cells from 56 children suffering from acute otitis media (AOM) and from healthy children were tested for adherence of a standard pneumococcal type ...

Prediction of Normal Values in Pulmonary Function Testing

Clinics in Chest Medicine, 1989
Appropriate use of reference equations for predicting normal values is important for maximizing the clinical and research usefulness of pulmonary function testing. Because of the diversity of clinical and research uses of pulmonary function testing, predictive equations derived from different populations may be needed for specific applications ...

The Predictive Value of Clinical Laboratory Test Results

American Journal of Clinical Pathology, 1978
Bayes' formula is being used with increasing frequency to calculate predictive values for positive and negative clinical laboratory test results. Because of its nonlinear form, however, it is difficult to visualize how changes in the test characteristics or disease prevalence will effect predictive values.
