DNA Testing - Orchid GeneScreen®
GeneScreen guarantees a probability of paternity greater than 99% or a three probe exclusion (no match on three loci). We offer a variety of paternity tests, including a non- maternal test in which the father and the child are the sole individuals tested, neo-natal and pre-natal tests, and a test which uses samples collected from grandparents to establish paternity.
DNA analysis requires blood or tissue samples. Tissue samples, usually buccal cells, can be collected quickly and painlessly by gently swabbing the inside of the mouth. In most cases, test results are returned in 15 days or less.
All information is kept strictly confidential, reports are mailed only to those individuals involved in the testing or their legal representatives. Telephone and fax reporting is not permitted.
Testing Standards of 99.0% or to establish an exclusion.
To ensure that cases are accurately reported all results are interpreted by at least two (2) qualified individuals. Results are checked visually as well as by computer analysis for confirmation of matching DNA fragments. Initial review is typically performed by a DNA Analyst, followed by computer sizing by a second qualified analyst with final review by the Laboratory Director or Associate Laboratory Director(s). GeneScreen has chosen to provide our clients with testing performed using Polymerase Chain Reaction (PCR). PCR testing for paternity determination has recently become the method of choice by a majority of the laboratories performing such services.
At a minimum, GeneScreen would run a paternity test utilizing eight (8) genetic markers. GeneScreen would continue testing until the contract requirement of the minimum probability of paternity of 99.0% is met or a minimum of three (3) exclusions is achieved. As a quality control method, two known DNA samples are tested along with the case samples on each gel run.
Statistical Calculations and Reporting scanning are automatically downloaded into a specially designed computer program for statistical calculations. This proprietary paternity calculation and report writer software package has virtually eliminated the administrative burden following data analysis. Validation throughout the peer review process by several DNA experts and population geneticists in the course of trial discovery and courtroom testimony in dozens of cases. Statistical information derived from these databases compares favorably with several other databases constructed in various locations throughout the United States. Statistical findings using GeneScreen’s database have been successfully introduced at trial in more than 200 cases. There are no circumstances in which GeneScreen’s database was not found to be admissible for trial in either civil or criminal proceedings.
