Blood results are often done on site in bigger vet practices as they have the machines that can run the samples through almost immediately.
You can get dipsticks to do a quick check on urine samples, but you need to be able to collect the sample properly (clean, uncontaminated and definitely only from one known animal). You also need to know how to read and interpret the results. Timing is critical to carrying out some of the tests. Vet nurses can do them while you wait.
You would be better getting a full examination and any follow up tests from a trained professional, rather than second guessing anything. If treatment is needed, you are still (legally) reliant on a vet to prescribe the correct drugs at the correct dosing regime. Getting them seen by a vet tomorrow is a good idea. If you can get a sample of urine from each, I would take that in as well.
