Why customers choose seeDNA for prenatal DNA testing

Today we introduce a survey response regarding prenatal DNA testing from a customer living in Aichi Prefecture. At the seeDNA Genetic Medicine Research Institute, we gather honest feedback from customers who have used our testing services and use it to continuously improve our service. This customer chose seeDNA based on the high level of trust conveyed by online reviews, media coverage, and our acquisition of the Privacy Mark.

Prenatal DNA testing is a test that uses the fetus's DNA information during pregnancy to confirm biological parent-child relationships. Paternity testing, which used to be possible only after birth, can now be performed safely during pregnancy thanks to advances in non-invasive methods using maternal blood [ref:1]. At seeDNA, we use this technology to provide testing services that place no burden on either the mother or the fetus.

Our commitment to customer support and rapid response

What this customer particularly praised was our "quick response" to inquiries by email and phone. By its nature, prenatal DNA testing is often a psychologically stressful experience for customers. That is precisely why seeDNA places the highest priority on responding promptly to inquiries.

This customer also experienced a case in which a re-test was needed after the first analysis. When a re-test is required, customers tend to feel anxious and rushed, but seeDNA strives to minimize waiting time by promptly re-shipping the test kit needed for the re-test. The customer told us, "The prompt re-shipment of the test kit was a great help," and this responsiveness is one of seeDNA's strengths.

Testing speed and results reporting timeline

The details of the testing speed the customer described offer very useful insight into seeDNA's actual operations. The specific timeline is as follows.

1. 1st time: Sample received on February 20 → Notified of re-test on March 5 (3rd day of the response period)
2. Prompt re-shipment of the re-test kit
3. 2nd time: Sample received on March 7 → Results notified on March 14 (2nd day of the response period)

As shown here, even when a re-test is needed, seeDNA delivers results within the previously communicated timeframe. The customer stated, "I was a bit anxious because a re-test was needed, but I'm satisfied that both times I received a response within the timeframe I had been told in advance," which shows how careful advance explanation and diligent schedule management build trust.

Readability and transparency of the report

The customer rated the test results report as "very easy to read." DNA test result reports contain specialized figures and data, which can be difficult for the general public to understand. At seeDNA, we have made original efforts in the layout and format of our reports so that customers without specialized knowledge can accurately understand their results.

Transparency in testing is an extremely important factor directly linked to customer peace of mind. At seeDNA, we clearly document not only the test results but also information on the genetic loci used in testing and the statistical probabilities involved, so that customers can verify the meaning of their results for themselves.

Preventing human error through our double-check system

This time, the customer asked a very important question: "What measures do you take to prevent human errors such as sample mix-ups?" This is a fundamental issue that determines the reliability of DNA testing [ref:2].

To prevent human error, seeDNA employs a double-check system that analyzes every test twice. This double-check involves the following steps.

• Independent duplicate analysis performed on every sample
• Cross-verification against previously accumulated data
• Rigorous confirmation that there is no sample mix-up or duplication
• Personal information management based on Privacy Mark certification standards

In DNA testing, a sample mix-up is a mistake that can never be allowed. seeDNA's double-check system doesn't simply test the same sample twice—by cross-referencing against our vast historical database, it can also detect any accidental contamination or mix-up. This multi-layered quality control underpins seeDNA's track record of "zero misjudgments."

Personal information protection and the significance of the Privacy Mark

One reason the customer chose seeDNA was our acquisition of the Privacy Mark. Because DNA testing handles extremely sensitive personal genetic information, a strict personal information protection system is required [ref:3]. The Privacy Mark is a certification granted by the Japan Institute for Promotion of Digital Economy and Community (JIPDEC), awarded only to businesses that handle personal information appropriately.

By obtaining and maintaining this Privacy Mark, seeDNA manages all personal information, including customers' genetic information, to the highest security standards in the industry. Strict rules govern everything from how test samples and reports are managed to data retention periods and disposal procedures.

For those considering prenatal DNA testing

When considering prenatal DNA testing, the most important thing is "choosing a trustworthy testing organization." As this customer did, we recommend comprehensively comparing factors such as reviews, track record, and personal information protection systems. At seeDNA, our experienced staff carefully assist customers from pre-test consultation through after-care. If you have any questions or concerns, please feel free to contact us.

Q2. Can a re-test be required? What about additional costs in that case?

A. Depending on the condition of the sample or the amount of DNA collected, a re-test may be necessary in some cases. At seeDNA, no additional fee is charged for a re-test. We also promptly re-ship the test kit needed for the re-test.

Q3. What exactly is the double-check system?

A. At seeDNA, we perform two independent analyses for every test. In addition, by cross-analyzing against our accumulated historical database, we rigorously confirm there is no sample mix-up or duplication.

Q4. How long does it take to receive the test results?

A. After we receive the sample, results are typically delivered within a few business days to around 10 days. We notify you of the results within the response period communicated in advance, so if you have any concerns about scheduling, please consult with our staff beforehand.

Q5. Is my personal information and DNA data secure?

A. seeDNA has obtained the Privacy Mark and meets the industry's highest security standards for managing personal information and genetic data. Strict rules govern the handling, storage, and disposal of samples and data.
