The Idexx Catalyst machines do them, easy enough to do.

You put the diluent in a separate sample pot in the machine, tell it you're doing a UPC and it does the dilution internally itself (same as it does if you want to do a dilution on a blood sample).

I use the dipsticks as a guide for further investigation alongside clinical signs, biochem changes, refractometer and sediment exam and depending on case and available funds would then submit to lab. I have found close correlation between the conclusions from the in house sticks, clinical suspiscion and lab report...quantitative accuracy maybe not but qualitative value of ratio has been very good so far

Out of interest how much does it cost?

You can pool 3 equal aliquots of urine from different days instead of running three separate tests

I've never run one on my own before, have to admit the nurses usually sort it, but it involves using a dilution tray (like the Idexx T4 slides). Is accurate.

You're probably aware that you also need to check for active urine sediment (as a possible cause of raised UPC) which adds to the costs for the owner.

Do people usually just do urine microscopy for one sample and then repeat a UPC without microscopy - to check that it is consistently raised ?

You can do it on renal profile rota (used to be easy on the Vettest when you could load individual slides - you may still have one of them) but you will need to dilute your sample considerably (can't remember how much but probably 10x) otherwise the creatinine will be above range and you won't get an absolute value.
