DNA Samples With No Paperwork Are Guaranteed to Delay Genomically-enhanced EPDs

Imagine this scenario: you plan to send DNA samples in on a group of animals for a genomic panel because you wish to get genomically-enhanced EPDs (GE-EPDs) on those animals. You contact ASA’s DNA Department and receive your paperwork to send with the samples. But then you remember those two additional samples in your office you’ve collected but haven’t gotten tested yet…surely it won’t hurt to just throw those samples in with the others without paperwork?

Here’s why that’s not the best idea: Ensuring you have DNA paperwork for each and every sample allows for the correct international ID to be attached to the sample. This unique number includes the association prefix, gender, and registration number. The genetic evaluation uses the international ID as a tracking number to match the animal’s genomic information with its pedigree and performance information in the ASA database.

If the lab receives samples that have no paperwork, those samples have not been assigned an international ID. In this case, the lab does the best they can with the information they have about the sample. Let’s say they receive a spare blood card with no paperwork that has a tattoo written on it. The lab will assign the proper association code, but they won’t know the gender or a registration number so that international ID will not match any animals in the ASA database. As a result, the genetic evaluation will not find any genomic information for that animal under its correct international ID. This means that the animal will not have GE-EPDs, even though the sample has completed genomic testing.

Build a foundation for successful genomic testing with DNA paperwork - each and every sample, each and every time.
