A walk-through of the paternity DNA testing process with our lab.

DNA Testing Laboratory Process

Step 3:

Biological relationships are identified. Once both profiles have been examined, it is time to analyse the data and compare the child's DNA profile to the alleged father's DNA profile. The DNA is examined and compared at 16 different locations (or DNA loci). If the child and alleged father do not match on more than 4 loci, the alleged father cannot be the biological father of the child. If the child and alleged father do match in a paternity test, a paternity index is calculated. The paternity indices for all matching loci are combined and used to calculate the probability of paternity. The probability of paternity is typically 99.99% or higher.
