Why are ketone levels in urine tests so high when you don't fast before the test?

Could panic attacks cause excess levels of catecholamines in urine tests?

Could panic attacks cause excess levels of catecholamines in urine tests?

Temporary, maybe: 24 hour urine tests for catecholamines are checking for epinephrine, norepinephrine, & other compounds that can be produced by catecholamine-secreting tumors called pheochromocytomas. Panic attacks alone might temporarily raise these levels, but not in sustained fashion like one of these tumors can. When present, pheochromocytomas can cause anxiety and panic attacks and raise urine catecholamines. ...Read more

If HIV does not survive in urine, then why do they offer urine tests to find antibodies?

If HIV does not survive in urine, then why do they offer urine tests to find antibodies?

Antibodies: Perhaps it is time to review basic biology. Antibodies are proteins made by the human to try to kill off or fight a foreign bug or virus. Antibodies are not the virus, are not the disease, and cannot cause an infection. Antibody testing is the most common way science has learned to diagnose viral infections. If you cannot accept the generous free medical support here graciously, then perhaps..... ...Read more

Please answer this question, in a way that is understandable. Are ''protein'' levels in urine tests measured by mg/dl, or protein-creatinine ratio?

Please answer this question, in a way that is understandable. Are ''protein'' levels in urine tests measured by mg/dl, or protein-creatinine ratio?

Both: Urine protein when measured as mg/dl does not take into account the concentration or dilution of urine. A 24 hour urine protein quantity would be the best thing to do. However, urine protein-cratinine ratio corrects for the concentration or dilution of urine and generally obviates the need to collect 24 hour urine. ...Read more

I have had an ultrasound and urine tests which are both normal. But im still getting something like a UTI, blood in urine and pain. What could it be?

R/O infection/stones: Hematuria is an important sign of illness. Neg. US is reassuring. Did the "urine test" check for infection? One should r/o tumor, infection, inflamation and stones.
