The Chromosome Analysis Cord Blood test is a combination of fresh specimens undergoing cell culture followed by a professional interpretation of the results by a team of experts. A total of about 20 metaphase cells are analysed in the test. It further includes the analysis of two banded karyograms. The total cost for the test is not inclusive of the analysis performed. However, if metaphase cannot be observed or is absent, charges for analysis are not taken. If at all, analysis has to be carried out, the test demands extra charges for it. You are misled if you believe that the test can detect and screen chromosome defects.
