We submitted a sample for testing but could not obtain fetal DNA (Google review)

A Google review posted by a customer who used seeDNA's genetic testing/DNA testing service

We were told that they could not obtain fetal DNA even though we had submitted a sample for testing.
We had no contact for two weeks, and worried something was wrong, we contacted them after the abortion.
The testing period had also greatly exceeded what was stated on their website, and the refund amount was less than half — it was money wasted.
If the testing period is going to be greatly exceeded, they shouldn't prominently state the number of days on their website.

Thank you very much for using our testing service and for sharing your feedback.

We are sorry that we did not adequately explain in advance that there is a range in the reporting date for results.
In order to prevent any possible testing errors, we perform the analysis twice with no additional cost or need to resubmit a sample, and because the amount of fetal DNA varies from person to person, we set a range of 7 to 9 business days for standard testing (3 to 5 business days for expedited testing).
We also apologize that this particular test resulted in the need for retesting, which understandably caused you great anxiety and led to a loss of trust in our company.

The reason for the retest was not a testing error. As you also mentioned in your review, it was because the amount of fetal DNA contained in the maternal blood was insufficient, which meant we were unable to provide an accurate test result.
For maternal blood samples collected from the 7th week of pregnancy onward, we have a track record of reporting accurate results to 95% of customers on the first test; however, because the amount of fetal DNA in the blood varies from person to person, a retest may still be required even when blood is drawn after the 7th week.

For this reason, we offer a free retest and a partial refund guarantee to customers whose blood was drawn from the 7th week of pregnancy onward.
Thank you very much once again for taking the time to share your valuable feedback with us.
We will continue to take our customers' feedback seriously and strive to improve our services, including the speed of testing.
