This grid is the typicaldesignation of body materials. Slight variations may occur due to raw material availability.1) Note the material designation imprinted on the valve body or associated tag. The marking includes the valve style, size letter, and body material.
Radial immunodiffusion (RID) is a technique that can quantitatively. determine the concentration of an antigen. Unlike many gel and liquid. precipitation techniques which qualitatively detect antigen, RID is a. sensitive quantitative technique that is often used clinically to detect. patient levels of blood proteins.
In terms of the type of dilator used, radial dilation (such as with the use of an inflatable urethra-specific balloon catheter) may be preferred over longitudinal dilation, as it avoids the possibility of longitudinal mucosal shearing, with submucosal hemorrhage, hematoma and/or inflammation.
