What are normal ranges for urine protein creatinine ratio?

What are normal ranges for urine protein creatinine ratio?

Well,: Up to 150 mg a day of protein may be excreted by a normal person.

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

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.

What does urine protein creatinine ratio of 23 g/ mol mean? I have been diagnosed with CkD G2A3.

What does urine protein creatinine ratio of 23 g/ mol mean? I have been diagnosed with CkD G2A3.

Mod prot in urine: There are two main components to kidney disease, which predict progression & treatment. One is function or the stage 1-5 with one nl and 5 severe & on or close to dialysis. Stage 2 in G2 is still considered mild & low risk. We next look at a protein called albumin and 23 g/mmol is moderate (>30) severe. In your question, you write CKD G2A3, I can't comment on the G, but 23 g/mmol is A2 - on tx?

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

Is a random urine Protein/creatinine ratio of 405mg/g something to be worried about, or no big deal? Is it only mildy elevated or high?

Is a random urine Protein/creatinine ratio of 405mg/g something to be worried about, or no big deal? Is it only mildy elevated or high?

Depends on context.: Lots of things can cause slight to mild proteinuria. In the context of diabetes this can be a sign of significant kidney problems from the diabetes and an early indicator that the kidneys are being damaged. Or... some contamination from menses. Needs to be put into the entire perspective.

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.

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).

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.

Trace protein in urine on and off for around 10 years. Lastly did a urine protein to creatinine ratio it was 0.13 with normal <0.2 blood cr 0.9bun 15?

Trace protein in urine on and off for around 10 years. Lastly did a urine protein to creatinine ratio it was 0.13 with normal <0.2 blood cr 0.9bun 15?

No concern: What you described is not a cause for concern. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.

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. ..

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.

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.

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.

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.

Do normal ''standard'' urine dipstick tests measure protein/creatinine ratio? Or do they only calculate protein by mg/dl? Please answer

ONLY PROTEIN: Standard urine dipstick only measures protein by colorimetric method. If urine is postive for protein, exclude false positive, eg fever, uti, exercise postural. If positive, quantify it by measuring both protein and creatinine in the urine.. 1+ corresponds to about 200-500 mg/24 hours, a 2+ to 0.5-1.5 gm/24 hours, a 3+ to 2-5 gm/24 hours, and a 4+ represents 7 gm/24 hours or greater.

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.

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.

My lab results show high levels of protein in urine 27 mg, urine creatinine 316.3 mg but levels of protein/creatinine ratio 90 mg. What does it mean?

Ur Protein/Cr ratio: The urine protein to urine creatinine ratio is an estimate of the 24hr urine protein. It is less cumbersome and quick. A urine protein to creatinine ratio of 0.15 or less would be consdered normal. For example urine protein of 30 and urine creatinine of 300 would be a upc of 0.1.

Urine results showed 100 mg/dL Protein in urine, Moderate Blood, Total Protein/Creatinine Ratio, Urine 319.7, Red Blood Cells, Urine 4-10, SEC many.

Sounds like you: Had a urine test for infection? Results look like you may have a mild UTI, though some of the numbers do not match up with the test acronym. Make sure you drink plenty of water and take antibiotics given with food. If you have pain on urination, the healthcare provider can give you some medicine to numb that area up for a couple of days.
