Paternity determination:
Today's DNA tests are used in many disputed situations in life and are increasingly popular due to the simplicity of their performance and their great efficiency (99.99 percent in paternity confirmation testing and 100 percent when paternity is ruled out). In addition to paternity, they also provide the opportunity to establish kinship, marital infidelity and identification of individuals.
Our private detectives are engaged in performing such tests for private clients, so that you can obtain preliminary evidence for filing an evidentiary application for an official test in accordance with the court procedure.
A DNA test to confirm or exclude paternity involves the analysis of a chemical substance containing the genetic code passed on to the child by the parents. Thus, a hair with roots, a piece of fingernail or epidermis, a person's secretions or even chewing gum are enough to establish the truth. During the forensic process, the blood of the mother, the potential father, as well as the child is used, and the mucous membrane found on the inside of the cheek is also effective.
Identification of biological traces:
Identification of biological traces. Thanks to modern technologies for studying nuclear DNA variation, it is possible to identify even small traces of blood, saliva, semen or sweat.
Minimal-sized biological traces left on envelopes, stamps or cigarette butts can be crucial for detecting perpetrators of crimes or eliminating suspects.
In cases where a mixture of male and female biological material is detected (e.g., in rape cases), analysis of male Y chromosome variation is used
For the identification of the most difficult biological traces, such as single human hairs devoid of hair follicles, mitochondrial DNA (mtDNA) analysis techniques are used - inherited in the maternal line
and resistant to external agents that degrade genetic material.
Identification of remains:
Personal identification of human remains of advanced age and very poor state of preservation. The remains, such as small skeletal elements, can be several to even several decades old.
Nuclear and mitochondrial DNA variation analyses are used in their identification.
Evolutionary origin:
Determination of the evolutionary origin (so-called haplogroup affiliation) of the Y chromosome (in the paternal line) and mitochondrial DNA (in the maternal line).
Such tests are usually performed at the request of individuals who are interested in their genetic ancestry. In some cases, the results of such tests also make it possible to determine ethnicity.
Thanks to the so-called molecular dating and phylogeographic analysis, it is possible to determine the time and place where a particular maternal or paternal line developed - for example, it can be determined that the woman who gave rise to the maternal line represented by the person under study lived about 15,000 years ago in the Middle East.
Our Warsaw detective bureau cooperates with one of the leading Academic Genetics Centers, so all research results obtained are unequivocal and reliable. confirmed by the relevant research reports.
