Is 3822.00 mmol/l normal 24- hour urine creatinine? Is 200.1ug/24h normal cortisol level for 24 hour urine test?

Is 3822.00 mmol/l normal 24- hour urine creatinine? Is 200.1ug/24h normal cortisol level for 24 hour urine test?

See below: Normal urine creatinine (24-hour sample) values range from 7-21 mmol/day (males) and 5-16 mmol/day (females). Results depend greatly on your age and amount of lean body mass. Normal urine 'free' cortisol (24-hour sample) is usually less than 50 ug (=mcg). ...Read more

Urine (Definition)

Urine is the product of the kidneys, which is produced to eliminate the waste products of metabolism, manage body fluid balance, &maintain acid-base balance. The blood is first filtered by the kidneys, and the composition of the resulting fluid is then altered depending on the body's needs. It is composed of mostly water, and breakdown products from blood cells impart ...Read more

How to keep creatinine levels above 20 mg/dl? I do not use drugs but need a drug urine test 3 times a week. The level of creatinine must be over 20 mg/dl. I changed nothing in my diet and recently had a level of 14.1 and was told i diluted. I am worrie

The : The most common reason for low creatinine is that you drink a lot of fluids. It is not abnormal to have low creatinine, it's just that the people doing the lab test want the urine concentrated enough that it can pick up trace amounts of the drugs they are testing for. Dilute urine= less of drug in urine sample. Some people have a medical condition that makes them unable to concentrate their urine (low levels of adh (vasopressin), (vasopressin) anti-diuretic hormone) release from the pituitary gland. If you don't have this condition, then on test days avoid liquids (sips ok, glasses not ok) until after the urine test. Best results would be to avoid liquids 4 hours before test. If creatinine is still low, you might want to see an endocrinologist to evaluate for low adh (vasopressin). If the doctor can validate this, then your employer can't legally hassle you about your low creatinine. ...Read more

If reference range is < 0.86 ng/mg for F2 Isospostane/Creatinine ratio urine test, what is normal reference range for just F2 Isoprostane urine test ?

If reference range is  < 0.86 ng/mg for F2 Isospostane/Creatinine ratio urine test, what is normal reference range for just F2 Isoprostane urine test ?

Oxidative stress: The F2-isoprostane/Cr ratio is the “gold standard” for measuring oxidative stress in people who have lifestyle risks due to poor diet or smoking, a family Hx of cardiovascular disease, or hyperlipidemia. ^ levels are seen in conditions with an incr risk of atherosclerosis and certain cancers. Urine values require creatinine in the analysis, range from 0.14 - 0.53 ng/mg w/ LC/MS, 1.02-1.30 w/ GC/MS ...Read more

My creatinine level was 56 and my gor is 56. Just had a urine test and ultrasound. I also have Gastroparesis. Does that play a role in my levels?

My creatinine level was 56 and my gor is 56. Just had a urine test and ultrasound. I also have Gastroparesis. Does that play a role in my levels?

Creatinine 56: No real relationship between creatinine and gastroparesis. And a creatinine of 56 probably not compatible with life. Please check the numbers and resubmit your question ...Read more

Slight foamy urine.spot urine test-protein 5mg/dl,creatinine 37mg/dl,albumin 2 mg/litre.Is it normal or proteinuria ?

Slight foamy urine.spot urine test-protein 5mg/dl,creatinine 37mg/dl,albumin 2 mg/litre.Is it normal or proteinuria ?

Proteinuria: We generally calculate the urine protein to creatinine ratio and as long as the ratio is below 300 mg/g it is considered not significant (yours is only 135mg/g) so your proteinuria is not significant. But the Albumin level you mentioned, is it serum (blood) Albumin level? If yes, it is very low and unlikely! Please verify your Albumin level and it's source (blood or urine) . ...Read more

For a spot urine test for 50lb girl , is trace blood, calcium 2.4 , creatinine 3.3 within normal range? If not what can it be from? How can I help her

For a spot urine test for 50lb girl , is trace blood, calcium 2.4 , creatinine 3.3 within normal range? If not what can it be from? How can I help her

As answered earlier: A spot urinary calcium to creatinine ratio of 2.4/3.3 is .72, which is high for age and means more calcium is being lost than normal. This can also explain the urine red blood cells, as calcium buildup in the kidneys has this effect.There are several possible causes. Followup with your doc at your scheduled appointment and complete the evaluation. ...Read more

Female white age 42. Primary hemochromatosis has caused stage 3cirrhosis. Now a urine test shows a creatintine level of 222.3. Should I be concerned?

Female white age 42. Primary hemochromatosis has caused stage 3cirrhosis. Now a urine test shows a creatintine level of 222.3. Should I be concerned?

Yes: The units are micromoles / liter, right? I'm really sorry that your hemochromatosis led to cirrhosis but the phlebotomy treatments you are receiving should at least partly reverse it. Your physician will work you up for the cause of what may be mild renal insufficiency. Some people like yourself get an IgA nephropathy secondary to liver disease; there are other possibilities. ...Read more

Low creatinine on a urine test, what caused that?

Low creatinine on a urine test, what caused that?

Several things: The most likely is inadequate collection of urine such that some of the 24 hour sample was discarded. Other causes are low muscle mass, which can occur in very small stature people, advanced age, bed bound individuals, and in patients with cirrhosis. ...Read more

I recently had a random urine test done, and my protein total random urine is 393. My creatinine two urine is 242.6. Is this high?

These results could: Be due to effects on the kidney from diabetes, hypertension, autoimmune, connective tissue diseases etc. Ask and get reassurance from your dr.

Will protein-creatinine ratio be calculated, if urine test only show ''traces'' of protein? Or do they only do it, if it's over 300 mg/l?

No.: Spot urine protein to creatinine ratio must be ordered separately. Trace proteinuria can be significant in some disease conditions such as diabetes, when microalbumin to creatinine ratio should be calculated. ...Read more
