Protein Total 24 Hour Urine Without Creatinine Biomarker Testing
It measures how much protein you lose in urine over 24 hours to assess kidney health, with easy ordering and clear results through Vitals Vault/Quest.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.
This test adds up the total amount of protein you pass in your urine over a full 24-hour period. Because healthy kidneys keep most protein in your bloodstream, higher urine protein can be an early sign that the kidney’s filtering system is under stress.
A 24-hour collection is different from a single “spot” urine sample. It can be more representative when protein loss varies throughout the day, but it also depends on collecting every drop of urine for the full time window.
This version is “without creatinine,” which means the lab reports total protein for the collection, but it does not include a creatinine measurement to help judge whether the collection was complete. Your result is still useful, but your clinician may pair it with other tests to confirm accuracy and identify the cause.
Do I need a Protein Total 24 Hour Urine Without Creatinine test?
You might consider this test if you have a urine dipstick or routine urinalysis that showed protein, and you and your clinician want to quantify how much you are losing in a day. It is also commonly used when there is concern for kidney disease from diabetes, high blood pressure, autoimmune conditions, or a recent illness that may affect the kidneys.
This test can also be helpful if you have symptoms that can go with significant protein loss, such as swelling in your ankles or around your eyes, foamy urine, or unexplained weight gain from fluid. In pregnancy, new protein in urine can be part of evaluating hypertensive disorders, although your obstetric team will decide which urine test is most appropriate.
You may not need a 24-hour collection if a spot urine albumin-to-creatinine ratio (ACR) or protein-to-creatinine ratio (PCR) already answers the question, or if your main goal is screening rather than precise quantification. Testing supports clinician-directed care and follow-up; it cannot diagnose the cause of protein loss by itself.
This is a laboratory measurement performed in a CLIA-certified lab; results should be interpreted with your symptoms, kidney function tests, and urine findings rather than used as a standalone diagnosis.

Get this test with Vitals Vault
Vitals Vault lets you order a Protein Total 24 Hour Urine test directly, then complete the collection at home and drop it off as instructed by the lab. Once results are ready, you can review them in one place and keep them for trend tracking over time.
If your result is abnormal or you are not sure what it means, PocketMD can help you translate the number into practical next steps to discuss with your clinician, such as which companion labs typically clarify the pattern (for example, kidney function blood tests, urine microscopy, or a spot ACR/PCR).
Because urine protein can change with illness, exercise, and medications, repeat testing is sometimes the most informative step. Vitals Vault makes it easy to reorder the same test under consistent conditions so you can see whether a change is persistent or temporary.

Key benefits of Protein Total 24 Hour Urine testing
- Quantifies your total daily urine protein loss when a dipstick or urinalysis shows protein.
- Helps distinguish mild, moderate, and heavy protein loss patterns that guide next-step evaluation.
- Supports monitoring of known kidney disease or treatment response when your clinician is tracking proteinuria.
- Can clarify whether swelling or foamy urine could be related to significant protein loss.
- Provides a time-integrated view that can be more representative than a single spot urine in some situations.
- Creates a baseline you can compare against future collections to see if protein loss is improving or worsening.
- Pairs well with PocketMD guidance to decide which companion tests best explain the “why” behind the number.
What is Protein Total 24 Hour Urine Without Creatinine?
Protein Total 24 Hour Urine measures the total mass of protein excreted in your urine over a 24-hour collection period. Most of the time, the proteins detected are albumin and other blood proteins that leak through the kidney’s filtration barrier when it is inflamed, damaged, or under increased pressure.
Healthy kidneys filter waste while keeping protein in the bloodstream. When the filtering units (glomeruli) or the kidney tubules are affected, protein can spill into urine (proteinuria). The amount matters: a small increase may be an early warning sign, while larger amounts can point to more significant kidney involvement and a higher risk of complications.
“Without creatinine” means the lab is not reporting urine creatinine for the same 24-hour collection. Creatinine in a 24-hour urine is often used as a reasonableness check for collection completeness. Without it, the protein number can still be meaningful, but it relies more heavily on accurate collection technique and clinical context.
How the 24-hour collection works
You collect all urine for a full 24 hours in the provided container, usually starting after you discard the first morning urine and ending with the first urine the next morning. Missing even one void can underestimate your total protein. Keeping the container refrigerated (or as instructed) helps preserve the sample.
Total protein vs albumin
Total protein includes albumin plus other proteins. Albumin-focused tests (like urine ACR) are often preferred for diabetes and hypertension screening because they are standardized and convenient, but total protein can be useful when non-albumin proteins are suspected or when your clinician wants a broad quantification.
What do my Protein Total 24 Hour Urine Without Creatinine results mean?
Low (or very low) total urine protein
A low result is usually reassuring and often reflects normal kidney filtering. Very low values are typically not a problem by themselves. If you had symptoms or a prior positive dipstick, a low 24-hour result can also happen if the collection was incomplete or if the proteinuria was temporary and has resolved. Your clinician may compare this with a urinalysis, spot ACR/PCR, and kidney function blood tests to confirm the overall picture.
In-range / expected total urine protein
An in-range result suggests your kidneys are not losing an abnormal amount of protein over the day. This is a helpful baseline if you are monitoring a condition that can affect the kidneys. If you are at higher risk (for example, diabetes or high blood pressure), your clinician may still recommend periodic screening with a spot urine ACR because it is convenient and sensitive for early albumin leakage. If symptoms persist despite an in-range result, the next step is usually looking for non-kidney causes or repeating testing under standardized conditions.
High total urine protein (proteinuria)
A high result means you are losing more protein than expected in a day, which can happen with kidney disease, inflammation, uncontrolled blood pressure, diabetes-related kidney changes, or certain autoimmune conditions. Higher levels are more concerning for clinically significant kidney involvement and may be associated with swelling, low blood albumin, or changes in cholesterol in more severe cases. Because this test does not include creatinine, your clinician may confirm the finding with a repeat 24-hour collection, a spot protein-to-creatinine ratio, and blood tests such as creatinine and estimated GFR. If the level is markedly elevated or you have symptoms like swelling, shortness of breath, or reduced urine output, prompt medical evaluation is appropriate.
Factors that influence total urine protein
Collection quality is a major factor: missing urine during the 24 hours can make protein loss look lower than it truly is. Temporary proteinuria can occur with fever, dehydration, intense exercise, urinary tract infections, and acute illness, so timing matters. Pregnancy, uncontrolled blood pressure, and high blood sugar can increase protein loss, and some medications can affect kidney function or urine findings. Your clinician may interpret your result alongside urinalysis (including blood and casts), urine culture when infection is suspected, and blood tests that reflect kidney filtration.

Frequently Asked Questions
What is a normal 24-hour urine protein result?
“Normal” depends on the lab’s reference range, but in general, healthy kidneys excrete only a small amount of protein per day. Your report will show the lab’s cutoff, and your clinician will interpret it based on your risk factors, pregnancy status, and other kidney tests.
How do I do a 24-hour urine collection correctly?
You typically discard your first morning urine, then collect every urination for the next 24 hours, including the first urine the following morning. Keep the container stored as instructed (often refrigerated). Missing even one void can underestimate your total protein.
Do I need to fast for a 24-hour urine protein test?
Fasting is usually not required. However, you should follow any instructions from your ordering clinician or the lab, and it can help to avoid unusually intense exercise during the collection because it can temporarily increase urine protein.
Why does this test say “without creatinine” and does it matter?
Some 24-hour urine orders include creatinine to help assess whether the collection was complete and to provide additional kidney information. Without creatinine, the total protein result can still be clinically useful, but your clinician may be more likely to confirm it with a repeat collection or a spot protein-to-creatinine ratio.
What can cause a high 24-hour urine protein result besides chronic kidney disease?
Temporary causes include fever, dehydration, strenuous exercise, urinary tract infections, and acute illness. Pregnancy-related conditions and uncontrolled blood pressure or blood sugar can also increase protein loss. Because causes differ, follow-up often includes urinalysis details, kidney function blood tests, and sometimes repeat testing.
How soon should I retest if my urine protein is high?
Retest timing depends on how high the result is and whether there was a temporary trigger (like infection or heavy exercise). Many clinicians repeat testing after the trigger resolves or within weeks to confirm persistence, and sooner if the level is markedly elevated or symptoms are present.
