Blood in urine that you can’t see?

Recently penelope went to the vet to have her teeth checked and nails trimmed. I’ve noticed she’s had quite smelly pee lately and have been giving her the Sherwood urinary support tablets that are supposed to be fantastic.
She ever so kindly peed on the table for the vet 🤣 and they tested it. He said there is blood in her pee but the naked eye can’t see it. It has to be seen under a microscope to see the blood. He sent home some baytril but has no idea what it could be. He said it could be a uti or stones, many different things. He said he saw no sludge or anything abnormal in her pee. He just said baytril should cure anything that could be causing this really small amount of blood in her pee.
Has anyone had experience with blood in urine that isn’t visible?

It's possible to have small amounts of blood in urine that aren't visible to the naked eye... combined with strong-smelling urine I would query a low-grade infection. Treating with antibiotics and looking for improvement is a good first step... should she continue to show blood in her urine following antibiotic treatment it may be time to look for another cause, such as a stone, kidney problem, reproductive tract problem, etc. But fingers crossed she will clear a simple UTI with Baytril!

Yes this is perfectly possible.
I have had 2 guinea pigs who have tested positive for blood in their urine but it was not visible when looking a he sample.
With Lucy it cleared up with Baytril, although it took 10 days, and with Ruby we ended up using Baytril and then switching to Septrin after 5 days as she didin't cope well with the Baytril.
But in both cases it did clear up with antibiotics.

The only other thing to consider is the blood possibly coming from a uterine issue (I am assuming Penelope is a girl).
But your vet has done the right thing dealing with the obvious possibility first.

Thank you for responding back! I had no idea blood could be in the pee like that without us seeing. She’s overall acting just fine and it doesn’t hurt her when she pees so that’s great!

Did you ever figure out what it was that Lucy and Ruby had?

Do you remember what the dosage was like for them? It’s okay if you don’t! I’m only asking because Penelope weighs 1.5 pounds and she was prescribe .10 every 12 hours. I felt like it seemed quite low but I don’t know the percentage of the baytril.
