Facilities and safety Equipment Process control Documentation Adverse events Assessments documentation, adverse events, assessments, service and satisfaction, and process improvement (Table 16.1). For the purposes of this chapter we refer to PGD as a process in combination with in vitro fertilization (IVF), involving the removal of one or two cells from an embryo and the subsequent testing of those cells for specific genetic disorders, characteristics, or chromosome number with a view to targeted embryo selection.

In PGD, a diagnosis has to be made using only one or two cells. To ensure the highest standards of analytic reliability and accuracy for such single-cell analyses, both general and single-cell specific quality control (QC) and quality assurance (QA) measures must be taken. As with any diagnostic procedure, there are generally three phases to consider: pre-analytic, analytic, and postanalytic.

The focus of this chapter considers the individual components of the quality system with respect to these three phases of testing (see Table 16.2, Table 16.3, and Table 16.

4), rather than discusses in any detail the various methods for design and optimization of specific PGD assays (which are described elsewhere). Finally, rather than providing exhaustive lists, we have used limited specific examples to illustrate some quality principles..

Components of the quality system Organization Pre-analytic PGD is a multidiscipli visual .net barcode standards 128 nary treatment that requires a well-defined organization scheme that includes all lines of responsibility across each of the different processes involved (ESHRE PGD Consortium, 1999; Geraedts et al., 2001).

In addition, it is of critical importance to set up clear lines of communication via email and through regular face-to-face meetings or teleconferencing, particularly if PGD is carried out in a transport or satellite setting.. Analytic Timing of the biopsy a barcode code 128 for .NET nd subsequent transfer of the cell to the diagnostic laboratory should be well communicated. It should be clear which test should be performed and under what conditions.

All these details should be included in a test request form presented to the diagnostic laboratory prior to the start of the procedure.. Postanalytic The organization schem Visual Studio .NET Code 128B e must include who is responsible for conveying the diagnostic result to the embryology laboratory, who is responsible for the final. 16: Quality control and quality assurance in preimplantation genetic diagnosis Table 16.2 Pre-analyti ANSI/AIM Code 128 for .NET c quality control/quality assurance measures for preimplantation genetic diagnosis.
