Please be advised these two are very very different. A genetic test is discrete and identifies the gene responsible for a certain disease. It will ascertain if a dog is a carrier, clear, or affected. Genetic tests can be done on the breeding pair actually at the puppy very young age puppy and categorically state that for this particular disease this puppy is clear or a carrier or affected.


Health screenings are what we still have when we don't have genetic tests available - which is for the bulk of the diseases that affect the YT and other purebred dogs.


For the Yorkshire Terrier there is only CDA as a genetic test - health screenings per YTCA are PRA LP evaluation and recommends BAT testing. There are more than a few health screenings I would recommend prior to breeding a YT.


Let me share with you a real story as a breeder of a large rare breed. Having waited for 3yrs for a show dog from a world renowned breeder I was finally on select for a female from this litter. I insisted on the genetic test be done for Hyperuricosuria - and despite what was posted as both dogs being clear for this genetic defect - guess what - I paid for the 2 show promise females to be tested - one (my pick) came back affected!! and one clear - I passed on the affected gal. My breeder was honest enough to show the results for both gals - and that for an autosomal dominant genetic trait told the tale. Which was one dog was bred that was Affected by this genetic trait. Let the breeder beware is the message here.


And IMO any breeder that does not know the difference between genetic tests and health screenings is not worth their salt! For they have not done even the minimal health education on breeding!
