Type of test: Different tests require different methods of testing depending on the purpose (e.g. parentage testing, genetic disease risk assessment, criminal investigation testing, etc.), and the cost will vary accordingly.
Analysis accuracy: The more accurate the test, the more data is used, so the cost tends to be higher. In particular, comprehensive genome analysis is expensive.
Trustworthy testing laboratories: Tests from accredited laboratories or university hospitals are often more expensive than rapid commercial tests.
Technological advances: The widespread use of technologies such as next-generation sequencing (NGS) and microarray analysis is enabling more accurate testing at lower costs than ever before.
2. Comparison of domestic and international DNA testing costs
The cost of DNA testing varies by country and region. For example, parentage testing provided by private companies in Japan costs around 30,000 to 100,000 yen, but in the United States it is often offered for around 100 to 300 dollars (approximately 15,000 to 45,000 yen), which tends to be relatively inexpensive.
Japan: Many genetic diseases risk assessment tests cost over 100,000 yen. Analysis at university hospitals and specialized institutions tends to be expensive.
United States: There are many commercial DNA testing companies, and in some cases tests to assess the risk of genetic diseases can be performed for around $200-500 (approximately 30,000-75,000 yen).
Europe: DNA tests for paternity testing and criminal investigations can sometimes be provided cheaply in countries with government support, but private tests are often expensive, costing between 50,000 and 150,000 yen.
In this way, differences in each country’s medical system and market competition have a significant impact on the price of DNA testing.
Advances in DNA testing technology and the potential for cost reduction
