Y-chromosome DNA Exclusion Test (MBE)Back

The principle of Y-chromosome DNA Exclusion Test (MBE)

Maternal blood Y-DNA test (MBY) must be done before conducting Y-chromosome DNA exclusion (MBE). If the MBY test results indicate that there is a detectable amount of Y-DNA in the sample submitted, then the expected mother can proceed to take the MBE test. The MBE test aims to analyze and compare the DNA markers, which are found by the fetal DNA in the maternal blood sample, with the alleged father's blood sample in order to find out whether their parent-child relation is excluded or not.
