Further studies of this and other tools are necessary to identify inexpensive practical tools for quantification of thickened liquid consistency. Thus, the results of the current study suggest that the LST may be useful in the broad categorization of fluids into therapeutically significant groupings but that it cannot be used more specifically to measure fluid viscosity. Viscosity TEST: 004861 CPT: 85810 Print Share Include LOINC in print Synonyms Serum Viscosity Expected Turnaround Time 3 - 5 days Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. Furthermore, the LST was not predictive of viscosity. Whereas the LST was able to separate the juices into nectar and honey categories, it was not able to separate barium mixtures into these categories nor compare barium to juices. Twenty-six liquids (10 powder-thickened 'nectar' juices, 10 powder-thickened 'honey' juices, and 6 barium mixtures) were assessed using both a viscometer for objective measurement of viscosity and the LST. The current study analyzed the utility of the Line Spread Test (LST) in this regard. This lack of standardization leads to variability in practice and points to the need for a simple tool for clinicians to assess thickened liquid consistency. The kinematic method uses gravity to force the. There are two methods for determination of the viscosity of a material, kinematic and dynamic, and both can be determined under controlled temperature. Intertek viscosity and rheology tests available vary according to the laboratory and location.Although dietary modification is a common treatment strategy used to manage dysphagic patients who aspirate thin liquids, there are no standard definitions for thickened liquid preparation. Viscosity is a relevant property of fluids when designing flow systems and industrial processes involving heat or mass transfer. Viscosity is often referred to as the thickness of a fluid, where water has a low viscosity and honey has a high viscosity. Intertek laboratories also conduct rheological analysis of samples. Viscosity testing of polymers and plastics: High Temperature, High Shear Viscosity: This book contains 9 chapters discussing the following topics: texture and viscosity of foods, how these properties are measured, and how they relate to.Saybolt Viscosity ASTM D445, ASTM D2161.Viscosity testing of petroleum, fuels, lubricants: Intertek labs test the viscosity of oils, chemicals, solutions, polymers and other materials to ASTM and other industry standards. Intertek viscosity tests measures fluid flow properties, and are useful for product evaluation, research and quality control. Test the Viscosity of petroleum, oils, fuels, chemicals and more to ASTM Standards
