Is there clinical benefit to routine enzyme testing of patients on statins?

Expert Opinion on Drug Safety, 2011
Statin-treated patients undergo frequent laboratory tests. This study evaluated the clinical impact of abnormal liver or muscle enzyme results.This clinical process evaluation study took place in six primary care clinics in Israel. Four hundred and eight patients (average age 63.8 ± 10.9 years) undergoing statin treatment, with at least one enzyme ...

[Designing and clinical testing of immune-enzyme and immunofluorescence test systems for serodiagnosis of ixodes borreliosis].

Vestnik Rossiiskoi akademii meditsinskikh nauk, 2004
The methods of immune enzyme assay (MIEA) and of lanthanide immunofluorescence analysis (LIFA) were used to work out the test systems for the detection (in blood serum of patients) of specific IgM IgG antibodies to the B. burgdorferi spirochete--a causative agent of ixodic borrelioses.

Applying and testing the conveniently optimized enzyme mismatch cleavage method to clinical DNA diagnosis

Molecular Genetics and Metabolism, 2012
Establishing a simple and effective mutation screening method is one of the most compelling problems with applying genetic diagnosis to clinical use. Because there is no reliable and inexpensive screening system, amplifying by PCR and performing direct sequencing of every coding exon is the gold standard strategy even today.

Helicobacter pylori Stool Antigen Test (Clinical Evaluation and Cost Analysis of a New Enzyme Immunoassay)

Digestive Diseases and Sciences, 1999
Noninvasive tests for Helicobacter pylori are increasingly used. Recently, an enzyme immunoassay for H. pylori detection in feces has been put on the market. Aim of this multicenter study was to evaluate the usefulness of this novel test as a predictor of H. pylori status in the pretreatment setting.

Clinical Correlation of Toxin and Common Antigen Enzyme Immunoassay Testing in Patients With Clostridium Difficile Disease

American Journal of Gastroenterology, 2003
The aim of the present study was to assess the correlation of Triage Micro Clostridium difficile Panel and toxin B cytotoxicity assay with the clinical diagnosis of C. difficile diarrhea.The subjects evaluated were 98 patients with diarrhea for whom stool was submitted for testing for C. difficile.

A Solid Phase C1q Enzyme Assay for Circulating Immune Complexes Adapted for Routine Clinical Laboratory Testing

American Journal of Clinical Pathology, 1983
An assay for circulating immune complexes (CIC) that is adaptable to a routine clinical laboratory is described. This solid phase C1q (SP C1q) enzyme immunoassay (EIA) uses commercially available reagents and is reproducible with CV% of less than 20% in the abnormal range.

Validation of a strategy for HCV antibody testing with two enzyme immunoassays in a routine clinical laboratory

Journal of Clinical Virology, 2008
Centers for Disease Control (CDC) guidelines require confirmation of hepatitis C virus (HCV) screening-test-positive sera with a low signal/cut-off (S/CO) ratio by recombinant immunoblot or PCR. The UK Health Protection Agency has suggested that a second enzyme immunoassay (EIA) could be used as an alternative for confirmation in non-immunocompromised ...

[Performance and clinical evaluation of antinuclear antibody test based on fluorescence enzyme immunoassay].

Rinsho byori. The Japanese journal of clinical pathology, 2014
The measurement of antinuclear antibodies (ANA) is used for screening of connective tissue diseases (CTD) in the laboratory. ANA detection is performed by indirect immunofluorescence (IF) assay on HEp-2 cells from human larynx carcinoma. However, it lacks specificity for the identification of specific diseases and antigen reactivity.

The Physiological Sources of, Clinical Significance of, and Laboratory-Testing Methods for Determining Enzyme Levels

Laboratory Medicine, 2014
Enzymes are organic molecules that accelerate biochemical reactions but emerge from the reaction unchanged. Abnormal levels of plasma enzymes are highly suggestive of damaged cells and provide clues to parts of the body that may be involved in disease processes. Enzyme levels are measured in the clinical laboratory to identify the site of damage and to
