Genetic Ancestry Test
Genetic analysis is for those who want to understand the origin of their family and the genetic context of their health. The test allows you to determine the geographical roots of the ancestors, identify family ties and give a more accurate idea of the genetic background, which may be important for the interpretation of medical data.

Analysis Description
The genetic basis of origin
Genetic origin testing is based on comparing individual DNA variants with reference populations collected worldwide. The frequency of occurrence of certain genetic markers in different regions allows us to assess which geographical areas the human ancestors originated from. The test is especially valuable for people who do not have complete information about their ancestry, for example, for adopted children, descendants of migrants, or families with lost archives.The analysis may include several levels:
Mitochondrial DNA, which is passed down the maternal line.
Y-chromosomal DNA, reflecting the paternal line.
Autosomal genetic variants that are inherited from both parents and provide the most complete picture of the origin.
Hundreds of thousands of genetic markers are evaluated for autosomal analysis, which makes it possible to determine the contribution of various regions of the world to the human genetic profile. The origin can be indicated both in broad geographical categories and at a more detailed regional level, taking into account the acceptable degree of statistical uncertainty.
The accuracy of the results depends on the reference populations used and historical migrations, so the data reflect a probabilistic rather than an absolute picture of origin.

Practical value and clinical context
Although the test is not intended to diagnose diseases, information about the origin may have clinical significance. The frequency of some genetic risk variants varies between populations, and the data may help the doctor interpret the results of medical genetic tests more correctly. In scientific and clinical research, genetic origin is increasingly used instead of conventional categories of race or ethnicity, as it provides a more accurate picture of the patient's biological background. This is especially important when assessing polygenic risks and interpreting rare genetic variants.
