I know the instructions do not mention urine. it is an off label use that some of the breeders are doing and having good results with. If anyone that is using this test is on here please share with me how many drops of urine you are using. thanks,
Make sure you either centrifuge the urine or let the sediment settle out before running the test. The sediment will stop the pores in the test.
If you make your email addy available either privately or to the list, I will pass your details on to the person who can answer your question
