Application of fluorescence in situ hybridization and chromosome karyotype analysis in prenatal diagnosis / 国际检验医学杂志

ABSTRACT

Objective To investigate the application value of fluorescence in situ hybridization (FISH)in prenatal diagnosis and compared with karyotype analysis of cells from amniotic fluid.Methods A total of 183 high-risk pregnant women received for a FISH and karyotype analysis who taken prenatal disgnosis in Meizhou people′s hospital between April 2012 and November 2013. Results According to the test results of karyotype analysis.There were 9 cases of chromosomal abnormality in 183 pregnant women.Among 9 cases,3 cases were trisomy 21,3 cases were trisomy 18,2 cases were XO and one case of XXY.One case of tri-somy 18 was showed normal using the FISH.Other cases were consistent with karyotype analysis result.Conclusion FISH is a rapid,reliable and prompt prenatal diagnosis method,combined with karyotype analysis will maximize the detection efficacy in pre-natal diagnosis of chromosome abnormalities.
