What is a paternity test?
Paternity testing, as the name suggests, is a scientific and technological means used to verify the authenticity of the biological relationship between parents and children. This technological method can easily obtain the personal privacy information of the test subject and process some unique biological information such as blood type and genes. Paternity testing can be widely used in medicine, personal identification, legal prosecution, etc.
Medical principles of paternity testing
The medical principle of paternity testing is based on genotyping of the subject\’s DNA sequence. Currently, commonly used paternity testing technologies on the market include PCR technology and STR technology, but no matter which technology, it is necessary to extract the DNA of the subject and conduct nucleic acid analysis on chromosomes 14 and 15 of the human genome to determine Is the parent-child relationship correct?
What subject does the paternity test pass
The subjects that need to be tested in the hospital with the help of professional equipment for paternity testing are mainly the medical laboratory department, medical genetics department and imaging department. The medical laboratory department is mainly responsible for testing the biological data of the subjects, determining their blood type, gene sequence, etc., and confirming whether the parent-child relationship is real by comparing the biological data of the parents; the medical genetics department needs to analyze the genetic traits and characteristics between parents and children. Detailed exploration of heterozygosity, etc. is required to confirm the existence of parent-child relationship; imaging disciplines require comparative analysis of the limb morphology, skull X-rays and other skeletal characteristics of the parents and the subject being identified.
Advantages of paternity testing
As a product of modern technology, paternity testing has multiple advantages. First of all, paternity testing can quickly and accurately determine the authenticity of the biological relationship between parents and children, avoiding risks such as genetic diseases and blood disputes caused by unknown parent-child identities. Secondly, paternity testing can play a positive role in combating illegal crimes and tracing identity history, which is conducive to the stable development of society.
Summary
Paternity testing is based on the genotyping of the subject\’s DNA sequence and can be used to determine the authenticity of the biological relationship between parent and child. The subjects that need to be tested in the hospital with the help of professional equipment for paternity testing are mainly the medical laboratory department, medical genetics department and imaging department. Paternity testing has the advantages of quickly and accurately determining the authenticity of the biological relationship between parents and children, and plays a positive role in combating illegal crimes and tracing identity history.
