Olivia Hayes89 said:I have no idea which lab ran this test or what specific methodology they used. However, in the lab where I work, the machines frequently flag positive Bilirubin, so we always double-check manually—alongside proteins, Urobilinogen, glucose, and nitrites. It’s entirely possible the machine threw a false positive here.
Since the blood work came back normal, I doubt the urine results carry much weight...
And from what I know, a urine culture usually takes about 2-3 days...
bluebadger12, does your urine sediment show nothing but leukocytes and bacteria?
I agree with you that the Bilirubin reading is likely a false positive; that's actually what I noted in my previous reply. Still, given that the ketones were also quite high, I’d suggest re-running the test just to be certain. Just to clear the air.
Considering that bluebadger12—based on what I gathered from his inquiry—was also dealing with bladder pain, and seeing these sediment results, a urine culture seems necessary. That’s why the doctor decided to order one.
Preliminary results can sometimes be available within 24 hours (a doctor might even get them over the phone), though final results typically take 48 to 72 hours in most cases.
