Differences in Coagulation Test Kits
Summary
The aim of this study is to assess the effect of Innovin® reagent on laboratory results when compared with the Thromborel® S.
Description
Thromboplastins are the screening tests which are used in the diagnosis of acquired or inherited disorders of the coagulation system but still, alterations between various thromboplastin preparations in the measurements remains a problem.Blood samples are going to drawn from patients receiving and not receiving oral anticoagulant therapy (OAT) during their routine laboratory tests. Samples are subjected to analysis by using Thromborel® S and Innovin® reagents. Mean International Normalized Ratio (INR), prothrombin time and fibrinogen values are going to compared. To further study the importance of this phenomenon the cohort will be divided into three subgroups according to the INR values as Group I: Patients not receiving OAT, Group II: Patients under OAT and INR values in good therapeutic range and Group III: Patients under OAT and INR values over the therapeutic range.

Medical and Biotech [MESH] Definitions
Indicators And Reagents
Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant & Hackh's Chemical Dictionary, 5th ed, p301, p499)
Placebo Effect
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
Cross-linking Reagents
Reagents with two reactive groups, usually at opposite ends of the molecule, that are capable of reacting with and thereby forming bridges between side chains of amino acids in proteins; the locations of naturally reactive areas within proteins can thereby be identified; may also be used for other macromolecules, like glycoproteins, nucleic acids, or other.
Enprostil
A synthetic PGE2 analog that has an inhibitory effect on gastric acid secretion, a mucoprotective effect, and a postprandial lowering effect on gastrin. It has been shown to be efficient and safe in the treatment of gastroduodenal ulcers.
Effect Modifier, Epidemiologic
Factors that modify the effect of the putative causal factor(s) under study.
