i think spin down time is within 20 mins

after obtaining a heprinised sample if left to stand before spinning the glucose continues to be metabolised and therefore giving inaccurate results. this is why a fluoride (yellow lid) sample tube is collected when sending away bloods to external labs. Well that's what I was told anyways.................

Yep me too, and also if you take a biochem sample to be run in house but not going to be carried out for a while the sample should be spun down quickly to prevent this (if in lith hep tubes).

I may be way off the mark here, but something in the very back of my brain is telling me that glucose levels can be inaccurate if the sample is left to stand for any length of time.... no idea about others though.

Like Steph said a higher protein diet can sometimes increas BUN levels, usually more to the higher end of the normal range. If other associated parameters were all normal chances are your vet wouldn't feel that there was need for further investigation. As for storage/incorrect handling, it can be common for haemolysis to occur which is a breakdown (bursting) of the red blood cells. When this happens the chemical constituent that is being analysed can lead to being increased/decreased depending on the test.

Lab work, particularly haematology and biochemistry is quite a large intensive topic but hope this helps a little!!

A high BUN can be from too much protein in their diet.. or dehydration (I think). .. As for bloods sitting in a car all day.. I know you get more accurate results if used when taken, I was told that if blood is sitting around all day, then cells can burst?? I'm not really sure.. we spin our bloods down and use the serum! - sorry I cant be much of a help! lol x
