1 Owen, William E.; Roberts, William L.Comparison of five automated serum and whole blood folate assaysSerum and whole blood folate measurements are used to establish folate deficiency. Most methods used in clinical laboratories are automated, nonisotopic methods that use folate-binding protein. Linearity, imprecision, and method comparison studies, including serum and whole blood hemolysates, wer...Folate assays; Serum folate; Whole blood folate; Automated assays2003
2 Owen, William E.; Roberts, William L.Performance characteristics of four immunonephelometric assays for the quantitative determination of IgA and IgM in cerebrospinal fluidMeasurement of IgA and IgM in cerebrospinal fluid (CSF) can be useful in the diagnosis of multiple sclerosis and other central nervous system disorders. The Dade Behring (Deerfield, IL) N Latex IgA and N Latex IgM tests on the BN II System and Beckman Coulter (Brea, CA) low-concentration IgA an...IgA; IgM; Immunonephelometric assays; Imprecision; Method comparison; Reference interval2003
3 Singleton, J. Robinson; Smith, A. GordonMicrovascular complications of impaired glucose tolerance.Impaired glucose tolerance (IGT) serves as a marker for the state of insulin resistance and predicts both large- and small-vessel vascular complications, independent of a patient's progression to diabetes. Patients with IGT are at significantly increased risk for death and morbidity due to myocardia...Microcirculation; Humans2003-12-01
4 Konnick, Eric Q.; Williams, Sheri M.; Ashwood, Edward R.; Hillyard, David R.Performance Characteristics of the COBAS HCV TaqMan ASR Using Armored RNA CalibratorsAs improved therapies have become available for Hepatititis C Virus (HCV) infection, the use of assays to quantitate HCV RNA has increased dramatically (3, 14, 16). The initial use of these assays was to predict the likelihood of therapy based on baseline HCV RNA levels. These reports indicated that...Roche Amplicor Monitor; NGI Superquant; patients2003-04-22
5 Stevenson, Jeff; Procter, Melinda; Hillyard, David R.Real time PCR assays for the detection of viral pathogens - are they the gold standard?Over the past decade, PCR testing for infectious agents in the clinical laboratory has begun to replace other methods, such as culture. PCR is often now referred to as the 'gold standard' in this field. Further evolution of this technology has seen the introduction of real time PCR, replacing tradit...Polymorphism; Target DNA2003-11-11
