You want a full genetic health condition panel rather than just the MDR1 marker, in which case a health-focused kit from the same brand or a competitor will cover more ground.

The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Overview
["This kit works with two cheek swabs that you roll against your dog's gums for about 15 seconds each, then air dry before sealing them back into their sleeves and mailing them in with the included prepaid shipping label. Wisdom Panel says results come back in roughly 2 to 3 weeks.", "The core draw is breed identification across more than 430 breeds, paired with the MDR1 health test, which looks for a gene variant that affects how some dogs process certain medications. It's built for all breed sizes and all life stages, and it also includes a relative finder to connect you with other dogs in the Wisdom Panel database who share DNA with yours.", 'At 18.14 grams, the kit itself is lightweight and ships in standard packaging with instructions, the shipping carton, and the swabs included. With 21,400 reviews at a 4.5 star average and about 3,000 bought in the past month, it has a large and active customer base.']

Performance notes
The swab-and-mail format is straightforward: two cheek swabs, a short air-dry step, and a prepaid mailer, with no special storage or refrigeration needed. Because this version only screens for the MDR1 variant rather than a full slate of genetic health conditions, it's best thought of as a breed identification test with one added health flag rather than a comprehensive medical screening.
What buyers say
With 21,400 reviews and a 4.5 star average, plus around 3,000 units bought in the past month, this is one of the more established breed test kits on the market, suggesting consistent results across a large number of buyers.
MDR1 is a gene variant found in some dogs, especially herding breeds, that can affect how their bodies process certain medications. This kit flags whether your dog carries the variant, but any medication decisions should go through your vet.
How long does it take to get results?
Wisdom Panel estimates about 2 to 3 weeks from the time your samples arrive at their lab, though actual turnaround can vary with sample volume.
Does this kit test for other health conditions besides MDR1?
No, this version focuses on breed identification plus the MDR1 marker. If you want a broader genetic health panel, look for Wisdom Panel's Essential or Premium tiers.
