Laboratory tests additive technology

However, the flow cytometers are bulky and expansive, and are available only in large reference laboratories. In addition, the required sample volumes are quite large, usually in the 100 pL range. Many clinical applications require frequent blood tests to monitor patients status and the therapy effectiveness. It is highly desirable to use only small amount of blood samples Ifom patients for each test. Furthermore, it is highly desirable to have affordable and portable flow cytometry instruments for field applications, point-of-care applications and applications in resource-limited locations. To overcome these drawbacks and to meet the increasing needs for versatile cellular analyses, efforts have been made recently to apply microfluidics and lab-on-a-chip technologies to flow cytometric analysis of cells. 

Toys sold in the USA are regulated by the Consumer Products Safety Commission, and the Code of Federal Regulations covers the toy safety standards. In addition, there are a voluntary set of standards established by the American Society for Testing Materials. This article visits a laboratory that helps test new toys, Specialized Technology Resources Inc., and discovers what some of the tests involve.
