Information updates policy and samples repetitions


tellmeGen's goal is for everyone to have access to their genetic information from anywhere in the world with an internet-connected device to share it with their trusted healthcare professional. To do this, we have developed a platform that stores, interprets and updates genetic information.

At tellmeGen we do large-scale genotyping looking for relevant clinical information, so we use Illumina's Global Screening Array (GSA chip) which contains more than 750,000 markers. In addition, it is customized with more than 5,000 single nucleotide polymorphisms or SNPs. However, as technology advances, we will be able to use larger genotyping chips or massive sequencing to provide more up-to-date and new information.

From tellmeGen we will support the previous chip versions used and will reflect the chip version used in the private area. If you wish to update the chip version, please contact us at [email protected] and we will provide you with the fastest and most efficient solution.

Conditions for repeating samples and obtaining results

tellmeGen is committed to delivering results to all users.

In most cases a single saliva sample is sufficient to obtain the results. However, occasionally it is necessary to obtain a new sample because the concentration of the DNA obtained and/or the quality of the sample is low and does not meet the minimum quality criteria to provide reliable results. This is generally due to incorrect sampling or problems in obtaining the sample (dryness, infections, use of medication or various pathologies).

If the first extraction and genotyping process does not yield results, tellmeGen will contact you via email to offer you the possibility to repeat the sample collection, DNA extraction and analysis on the Illumina® genotyping array free of charge. You also have the option to request a full refund, with the exception of the handling and shipping costs (€50). You have a period of 3 months from receipt of notification of this situation by e-mail to respond to us with your choice. If we do not receive a response within that period of time, we will consider the sample void and will not be able to refund or repeat the process for free.

Repeating the sample collection, extracting the DNA and analyzing it a second time does not guarantee that the results will be satisfactory. There are exceptional cases, in which it is not possible to obtain results from saliva/mouth swabs and a blood sample must be taken. tellmeGen does not offer the service of obtaining blood samples.

The saliva sample analysis may be repeated up to three times. The cost of the analysis of the third sample shall be borne by the client. The analysis will not be repeated a fourth time. In these cases the amount paid for the analysis will be refunded minus the handling and shipping costs.

Minimum criteria for sample quality

1. Greater concentration of DNA obtained: 50 ng / ul

2. Quality of the obtained sample: Call rate> 0.95
