<h1>Automated Measurement of Plasma Viscosity with a Capillary Viscometer.</h1><strong> Author: <a href='http://www.articleseen.com/profile_Viscometer.aspx'>Viscometer</a></strong><br /><p>Plasma viscosity has several advantages over the erythrocyte sedimentation rate to acute phase response over the 24-hour measurement. A new capillary viscometer (II Coulter viscometer), which provides automatic measurement of plasma viscosity in comparison with the International Committee for Standardization of Hematology selected manual method (Harkness viscometer). Automated measurement of plasma viscosity at 25 ° C showed close correlation (r = 0.979, p less than 0.002), the selected method 160 plasma samples. Viscosity values ??of satisfactory accuracy of both parties and the party (1.7% or less of variation coefficients) were obtained to 5.7 mPa × s. There was no detection of transfer between the sample and the viscosity values ??of the ambient temperature range 15-32 degrees C. The careful daily cleaning was required to prevent the accumulation of protein during the automatic sampling valve measures have been properly corrected. Automated measurement of plasma viscosity is an attractive alternative to the measurement of erythrocyte sedimentation rate. We recently conducted an Ames Clinitec 200 similar to Doran and Kensit 'on 774 consecutive urine samples in our lab for evaluation. In our study we compared a number of reagent strips Clinitec 200 tests of blood, protein, nitrite and leukocyte esterase to read our standard method of urine culture, Bacteruritest strip (mast Laboratories) infected with CLED agar plates and incubated overnight in air-37c. The aim of the study, one or more positive reagent strip tests and any> 10 'bacteria / ml of pure or predominant growth of a culture was taken to positive results. We do not test our specimens for antimicrobial agents. We recently conducted an Ames Clinitec 200 similar to Doran and Kensit 'on 774 consecutive urine samples in our lab for evaluation.

The basic equation, in combination with a newly developed shear deformation fields, calculated from the velocity measurements obtained µPIV technique of spatial characteristics of the blood viscosity. Physiological levels of blood hematocrit and aggregation was sheared narrow gap plate plate geometry and the velocity and clustering features of the set of images to capture high-resolution video camera. Combining the blood-induced changes in microstructure were observed effect on the flow characteristics. At low shear rates, high aggregation and network formation caused by RBC motion is essentially two-dimensional. The measured velocity fields was to evaluate the shear size, which was then used in conjunction with a new model to evaluate the spatial variation of viscosity throughout the flow field. It was found that no single microstructural properties of the blood influenced the viscosity of the distribution. Issue in evaluating the flow core, using a zero velocity gradient at the basic premise of blood viscosity profile, it was found that considerably higher than the effective viscosity is determined using the following assumptions velocity profile.</p><strong>About the Author:</strong><br />Visit viscometer.co for all types of <a rel="nofollow" href="http://www.viscometer.co/">viscometer</a> according to your need.<p> Article Source: <a href='http://www.articleseen.com/Article_Automated-Measurement-of-Plasma-Viscosity-with-a-Capillary-Viscometer_141542.aspx'> http://www.articleseen.com/Article_Automated Measurement of Plasma Viscosity with a Capillary Viscometer._141542.aspx</a></p>
