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

Urine protein/creatinine ratio 2225 mg/g what does that mean?

Urine protein/creatinine ratio 2225 mg/g what does that mean?

Needs confirmation : It means you have around 2 gm of protien in the urine which is very abnormal. This needs a confirmation by repeating the test and be sure you don't have other reason to explain it like UTI or blood in the urine. If confirmed, then needs comprehensive work up to determine the reason. Diabetes is very common one but there are multiple systemic and/or kidney diseases that could cuase it ...Read more

What is the formula to calculate urine protein creatinine ratio?

What is the formula to calculate urine protein creatinine ratio?

See below: The protein-to-creatinine ratio is a calculated value. The amount of urine protein and creatinine in a single specimen is measured in the lab. Each value is expressed in milligrams per deciliter. The amount of protein is divided by the amount of creatinine. ...Read more

Urine protein creatinine ratio results shows in which unit is it mg/dl or mg/gl. Protein is 423 mg/dl. And creatinine is 91 mg/dl. So what is my PCR.

Significant: The protein/creatinine ratio is 4.6, which roughly corresponds to 4-5 grams of protein per 24 hours. This is clearly abnormal and consistent with the nephrotic syndrome. This requires investigation by Nephrology, likely to include a biopsy of the kidney (a safe and common procedure). ...Read more

Urine protein randm: 11.7, urine creatinine randm: 304 high (ref 58-161), protein/creatinine ratio: 38.44. What does tht mean? Do i need more test?

Urine protein randm: 11.7, urine creatinine randm: 304 high (ref 58-161), protein/creatinine ratio: 38.44. What does tht mean? Do i need more test?

Proteinuria: You have proteinuria (p) and the first thing is to have a 24 hour urine collection to see the amount of protein in your urine and to assess your kidney function. Have a renal ultrasound to assess kidneys' size depending on the p, i would send off blood for aso, anca 2, complement c3 and c4, hiv, hepatitis b antibody to see if a cause could be found for the p, if not a kidney biopsy may be needed. ...Read more

Random sample: urine protein 31mg/l urine albumin 5.00mg/l urine creatinine 3.894mmol/l urine albumin creatinine:ratio 1.3mg/mmol is this normal?

Random sample: urine protein 31mg/l urine albumin 5.00mg/l urine creatinine 3.894mmol/l urine albumin creatinine:ratio 1.3mg/mmol is this normal?

Is this a test?: Slight variation in the reports from different laboratories does exist. So, please refer to the attached normal range for interpretation. I'm sure there is such information for you to reconcile. If any doubt, talk and confirm with the attending doctor. Best ... ...Read more

Urine creatinine 24hour is 18.5 (7.1-17.7mmol/d) and my urine protein 24hour is 0.14 (<0.15g/d), I have IgM k monocloncal protein in b2 what is this?

Stop worrying: Reference ranges are where most people fall; there's no reason at all to get upset about a trivially high creatinine on a test that is done only to make a ratio with the albumin, which seems quite normal, thanks. My own guess is that your physician is eager to reassure you, and i'd urge you to accept this. There's much good in your life & future -- keep your eyes there. ...Read more

Urine protein to creatinine of 206/1.8 or 2. Do i need ACE or arb inhibitor for protein problem? I'm conerned about side effects.

Forgive my frankness: Even if you have significant proteinuria, nobody here can advise you about medication without a big picture ofyour health. The most common cause of proteinuria is simply standing up -- several percent of people are like this, and a first-voided morning urine without significant proteinuria would confirm this if it's you. Don't treat lab values and demand to understand your workup. ...Read more

How can i compute the 24 hr urine protein and 24 hr urine creatinine? thanks, Doc!

How can i compute the 24 hr urine protein and 24 hr urine creatinine? thanks, Doc!

Need more info : Need more information as to why you want to know. The answer depends on that, and I'm not quite sure if you mean "interpret" rather than "compute." For what reason did you have the test done? Remember, in regards to tests, numbers are just numbers - the context in which they exist is where the importance lies. Please discuss with your physician. ...Read more
