Paternity consultant Allen Gelb - list of forensic testing, paternity testing, genetic testing, and blood testing services. There are two types of DNA testing with RFLP being more sensitiv e and therefore is more conclusive. Allen Gelb has over-turned the other DNA test in courts. Because of the sensitivity and huge database RFLP testing permits motherless testing. The laboratory extracts the DNA from the swabs which collect skin cells from inside the cheeks.
Buccal swabs are better than blood.
Prenatal Paternity Testing Amniocentesis or CVS can be performed for prenatal paternity testing between the weeks 10-20. We use the amniotic fluid and the swabs from the mother and alleged father to obtain a conclusive answer regarding paternity in about 10 days. It is, unfortunately, more expensive than post partum testing which can be performed as early as the first day after birth. The answer is sent directly to the embassy. INS accepts this laboratory's report for immigration purposes.
