DNA Testing Step by Step Process

  1. Make DNA request on MyHerd or call the AHA office.
  2. If requested on MyHerd, go to “pending transactions” and pay for DNA request.
  3. After DNA request is paid for, the DNA sample submission form is emailed or mailed to you.
  4. If emailed, open DNA sample submission form from AHA and print it.
  5. Collect DNA sample.
  6. Mail DNA sample submission form with DNA sample attached to GeneSeek.
  7. GeneSeek processes DNA, generates results and returns data to the AHA.
  8. DNA results are made available on MyHerdorg the same day, or you will receive a results statement via email.

Sample Collection

The AHA accepts hair, blood (blood cards), semen and tissue sampling units (TSU) samples.

Understanding Results

A results statement will be available to you via email or mail once the AHA receives results from the lab. The results will notify you if the parentage qualifies and of any abnormalities (normal or carrier). If requested, you will be able to view GE-EPD or H/P status results.

Parentage results

  • PV (parent verified)
  • SV (sire verified),
  • DV (dam verified)

Horn/Polled results

  • HH (homozygous horned)
  • PP (homozygous polled)
  • HP (heterozygous horned)
