The use of bile acids in screening clinically normal dogs for liver shunts is not currently being advised due to the variation of normal bile acid levels in Yorkshire Terriers, and other breeds as well.

It is my understanding that yes, you can get false positives. Usually during the puppy stage, when so many things are going on with said pup. And of course as Dr Center's states, the importance on equipment and how the blood is drawn.
However, I'm a bit perplexed on the last statement of not conducting bile acids if a dog is not showing clinical signs of LS.....whereas, Dr Center has always stressed all Yorkies be tested......Gonna check on clarification.
