Autosomal Maternal Serum Paternity Test

 
Autosomal Maternal Serum Paternity Test
Unlike Y-Chromosomal paternity testing, Autosomal Maternal Serum Paternity Test requires extremely advanced techniques for the separation and differentiation of fetal cf-DNAs. In normal circumstances, fetal cf-DNAs will be existing as low as 1% in the maternal plasma, and leading to the detection of fetal cf-DNAs difficult. In addition, due to the fact that the female baby's DNA signal will be significantly masked by maternal DNA, this makes the analyzing and extracting the fetal DNA further problematic.

Hong Kong In-house R & D
Medtimes Molecular Laboratory has spent over 2 years in-depth on this research and studying the characteristics of fetal cf-DNAs, we are a modern laboratory equipped with up-to-date instruments and tools. Our R&D team has finally came to the concluding stage of this research and are pleased to announce the novel non-invasive paternity testing.

Non-invasive
Non-invasive maternal blood paternity is a completely new molecular test combining the techniques of using cell-free DNA (cf-DNA) and single-nucleotide polymorphism (SNP) technology. Cell-free fetal DNA-based non-invasive prenatal testing (NIPT) has been developed over a decade, it enables the diagnostic and screening of fetal DNA without the invasive procedures.

Gestational Week: 7 weeks
Usually, methods of sample collection for prenatal parentage testing include Chorionic Villus Sampling or Amniocentesis. These methods are not only invasive, but cannot be conducted until at least 10 weeks into the pregnancy. However, at Medtimes, we are able to perform the parentage test by using the blood of the mother (maternal blood). Currently, this is the only non-invasion prenatal paternity testing method, and can be performed after the 7th week of pregnancy.
