924. Follow-up: The Guinea Pig that passed fresh blood in the urine

Yesterday, Mar 29, 2012, the lady brought her guinea pig to Dr Daniel at 1pm for consultation as he had passed blood. This guinea pig had been to other vets and we at Toa Payoh Vets was seeing him for the 3rd time today.

First time, I had collected urine for analysis and X-rays.
See case at:

"But no blood in the urine was seen," Dr Daniel told me in the evening when I asked him.
"Did you collect urine and send for analysis?" I asked.
"Yes," he said. "The urine is clear. Collected 6 times."
"What could be the cause of this blood in the urine?" I asked.
"5 possibilities," Dr Daniel said. "Trauma, infection, tumour, coagulopathy and toxins. The owner realised that the guinea pig had been given a shower a day before and blood came out in the urine. As in previous times."
"Was the guinea pig bathed before this, in the past 2 weeks since the last complaint?" I asked.
"No," he said.

So, was it the shampoo? The guinea pig started eating hungrily yesterday but was off food 2 days ago.

"Has he lost weight?" I asked.
"50 grams," he said.

"Tumour was diagnosed by one vet," Dr Daniel said. "Since he is one year old, it is unlikely."
"But it is possible," I said. However, the last 2 times the GP came, no blood was present in the urine. So, it is a mystery.

So, we wait for the urine test result. It is a puzzling case.
