Claim.
This section applies to prenatal diagnostic services have been qualified medical and health institutions, the use of cytogenetic methods and other nationally recognized
Related technologies, the implementation of fetal chromosomal examination of pregnant women, so the fetus is suffering from the present cytogenetic technology can be diagnosed chromosome disease
Pre-production diagnosis.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Cytogenetics prenatal diagnosis cytogeneticprenataldiagnosis
Through cytogenetic technology, fetal cells derived from the number of chromosomes and structural analysis of the inspection, so as to whether it exists
Diagnosis of chromosomal abnormalities.
2.2
Karyotyping
A specific number of somatic cells and the shape of the chromosome called karyotype (karyotype). The metaphase cells were stained with chromosomal specimens
Chromosome counting and band pattern analysis, known as karyotyping.
2.3
Chromosome counts chromosomecounts
The number of centromeric chromosomes in a number of metaphase cells was counted under a microscope.
2.4
Analyze cellcels analyzedcels
Under the microscope, or computer image processing, or according to the photos of specimens with metaphase cells in the morphology of each chromosome was analyzed thin
Cell number.
2.5
Karyotype analysis of cells karyotypedcels
Chromosome photos or computerized images of one cell are grouped according to the ISCN.1995 or ISCN.2005 rules,
Team, paired and morphological analysis of the number of cells.
2.6
Evaluate cell number scoredcels
Used to assess the number of cells in the specimen that need to be analyzed for the presence or absence of a particular cytogenetic trait. Generally due to patients
A certain clinical history, or in the analysis found that there are 1 to 2 abnormal cells. The number of cells evaluated is usually prescribed by the laboratory supervisor, this standard
