The report card of amniocentesis results can generally be analyzed by fluorescence immunohybridization report, karyotype analysis of chromosomes and the results of chromosome gene chip. 1. Fluorescence immunohybridization report: The first part of amniocentesis is the fluorescence immunohybridization report, which is the result of rapid test. It is mainly used to determine the absence of abnormalities in trisomy 13, trisomy 21, trisomy 18 and sex chromosomes. 2. Karyotype analysis of chromosomes: If the first part of the report is abnormal, the second part should analyze the karyotype of chromosomes. It is mainly to see whether the number of chromosomes is normal or not, under normal circumstances, the number of chromosomes should be 46. 3. Chromosome gene chip test results: through the chromosome gene chip test to determine whether there are deletions or duplications. The above three points can basically analyze the report of this amniocentesis, but we should also listen to the doctor’s judgment in order to avoid mistakes.
