Is suboxone detected in urine tests?

Is suboxone detected in urine tests?

No, unless...: Suboxone normally is not detected on standard tests used by your employer etc. It can be reliably detected, along with its metabolites, on a specialized test. Many of the laboratories are now moving to specifically test for buprenorphine – Suboxone. I wish you luck by the way, if it is prescribed legally, there is no problem of having it in your urine ...Read more

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

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

Not so: Usually skipping a few meals produces mild ketonuria, and non-fasting isn't a problem here. Is there a misunderstanding? High ketone levels have a variety of causes, most importantly diabetic ketoacidosis and aspirin poisoning. ...Read more

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 went for a urinalysis but I drank a lot and my urine was almost clear colored. Will the test be accurate as to bacteria in urine? Or too diluted?

Reasons for 15 Ketones in urine for past 6 months? Non-fasting urine tests. Not on diet. Not diabetic (blood glucose 95). Chronically ill 10+ yrs.

Few other causes: Uncontrolled diabetes and prolonged fasting = common causes, but hyperthyroidism, pregnancy, fever, inadequate carbohydrate intake such as those doing special diets like Atkins' diet. Excessive exercise and dehydration may show some ketone on urine. Some drugs may also do this. Since you said you are chronically ill for 10+ years...you may want to consult doc for evaluation. Good luck! ...Read more

My sis has high protien in urine tests shown it 8.5. Her urine also has a strong smell. Some times she got her feet swollen, eyes. What is it?

See doctor: I am assuming that it is 8.5 gms of protein in the urine in 24 hours. You should have her talk to her doc and be seen by kidney doctor. Seems like she has lot of protein in the urine. Is there blood in the urine also? Check blood for kidney function test. Restrict fluids and salt-also needs more treatment. ...Read more

26 f, microscopic hematuria detected inconsistently in urine tests. Blood tests show kidney function is fine. Should I be worried/see a urologist?

26 f, microscopic hematuria detected inconsistently in urine tests. Blood tests show kidney function is fine. Should I be worried/see a urologist?

Constant hematuria: If you have no urinary tract infection, you need go to a urologist to assess your urinary tract. You will need a renal ultrasound and probably an intravenous pyelogram to see if there are any problems with your kidneys. If these studies show no problem, you will need to have the urologist do a cystoscopy so your urinary bladder's wall can be visualized to see if you have any abnormalities there. ...Read more

I've been having tiny black bits in urine on and off for a month. What can cause this? I'm a female and I've had urinalysis that come out normal.

I've been having tiny black bits in urine on and off for a month. What can cause this? I'm a female and I've had urinalysis that come out normal.

Here are some...: One thing for sure is you, most likely, okay since you have been free of urinary / genital symptoms. Clinically, what you observed and described could represent the presence of amorphous crystals in alkaline urine which refects what you consumed or the possibility of contamination in urine collection. So, live on as the first choice or seek evaluation/counseling as suggested if insisting or obsess ...Read more

Microscopic hematuria is defined as the presence of three or more RBCs per high power field. Exercise-induced hematuria can be defined as gross or microscopic hematuria that occurs after strenuous exercise and resolves with rest in individuals with no kidney or urine tract ds ...Read more
