The market price for DNA testing depends on the type and purpose of the test, the services offered and the region. In general, the market prices for DNA paternity tests and other DNA tests in Japan are as follows

1. The market price of paternity appraisals

A paternity test is used to confirm the parent-child relationship between a child and his or her father or mother. Typically, the basic cost of a paternity test to confirm a DNA match between parent and child is as follows

Home DNA testing kits: 30,000-50,000 yen
This is a form of DNA identification in which a sample (saliva or oral cells) is taken at home and sent by post to a DNA testing agency. It has no legal proof capability, but is suitable for private confirmation of parent-child relationships.
Legal DNA testing (for court and administrative proceedings): 70,000-100,000 yen
This is an appraisal that requires rigorous procedures and certification in order to be used as legal evidence. Samples are taken at designated locations and can be submitted as evidence along with formal documentation.

2. other DNA testing quotes

In addition to parent-child appraisals, there are also sibling, grandparent, uncle/aunt or twin appraisals. These are often slightly more expensive than parent-child appraisals.

Sibling and grandparents’ appraisals: £60,000-100,000
This appraisal is used to confirm genetic relationships with siblings and grandparents. The cost is slightly higher because several samples are analyzed at the same time.
Twinning: 50,000-80,000
This test is used to confirm whether the twins are identical or fraternal.
Genetic screening (assessment of genetic disease risk): 50,000-200,000
The test is designed to assess genetic disease risk and the likelihood of genetic disease in the family. The cost is usually higher due to the detailed analysis of specific genes.

3. Differences between inspection bodies

Costs vary depending on the institute carrying out the inspection. There can be differences in costs between private national laboratories and those with an international presence. Legal appraisals are more expensive because they follow strict protocols, while private appraisals may be offered at a relatively low cost.

4. Additional costs

Expedited results option: it usually takes two to three weeks to receive the results of an appraisal, but you can pay an additional fee to receive the results sooner. This option may cost an additional fee of between JPY 10,000 and JPY 30,000.
Additional sampling: additional samples from more than one person may incur an additional charge of between JPY 10,000 and JPY 20,000 per person.

Summary

Private parent-child assessments: £30,000-50,000.
Legal paternity test: 70,000-100,000
Sibling or grandparent appraisal: 60,000-100,000.
Additional options: express delivery options and additional samples are charged separately.

Depending on the purpose of the appraisal and the level of proof required, costs may vary, so it is advisable to check with the organisation offering the right service for your purposes before commissioning a test.
