* 5 out of the 6 dogs that tested 1 - 49% had clots in their samples and needed retests. 3 dogs in the 50 to 69% needed a retest due to a clot. Some of the dogs that retested ended up in the high normal group (101 to 180%). So, when evaluating the data - realize that nearly all of the low results are due to sampling errors/clots.
