Description
The DEPOHGEN® test is a pharmacogenomic screening tool developed by Dr. Michael Court, a veterinary pharmacologist and geneticist at Washington State University. Dr. Court’s research explores how genetic differences influence drug responses in animals, with a focus on improving safety and treatment outcomes. This test detects a specific genetic variant linked to Delayed Post-Operative Hemorrhage (DEPOH) in dogs. Using a PCR (Polymerase Chain Reaction)-based assay, the test amplifies and analyzes DNA from a cheek swab or blood sample to determine the presence or absence of the risk-associated variant.
Specimens Required
Two specimen types are accepted:
1. DNA Collection Brush (cheek swab) OR
2. Whole Blood (EDTA tube)
Both types of specimens provide sufficient DNA for analysis; choose the one most convenient for you or your client.
Turn-around time: Results available on Fridays for samples received by Wednesday.

Special Instructions
A test sampling kit (includes two brushes, a pouch, and a return mailer) is available at no extra charge when you order the DEPOHGEN test.
Alternatively, brushes may be purchased: medical cytology brushes (recommended) or interdental brushes. “Sponge” type DNA collectors are not recommended.
If you use interdental brushes without a sleeve, once the brushes are dry you should put them into a small envelope or resealable plastic bag and write the name of the pet on the outside. Use separate envelopes/bags for each pet to avoid cross-contamination.
Labeling Instructions:
- DNA Collection Brush: Label the paper backing of the swab sleeve with the dog’s name, the owner’s first and last name (or veterinary clinic), and the dog’s breed using a pen or permanent marker.
- Blood Sample: Label the tube with the dog’s name and the owner’s first and last name.
- Important: Ensure that the name on the sample matches exactly with the name on the submission form. Unclear or mismatched labeling will prevent testing.
Note: There is an addition $10.00 charge for international orders.
