An unusual kidney test result or a change in urination can raise many questions. Does it mean you have kidney disease? Do you need a specialist? And what should you do while waiting for an appointment?
A kidney specialist, also called a nephrologist, can help assess and manage kidney problems. Your doctor may recommend a consultation if your kidney function is falling, protein remains in your urine, a kidney problem has no clear cause, or you need help managing complications. You do not have to wait until symptoms become severe: early kidney disease often causes no symptoms at all.
Not every abnormal result means permanent kidney damage or requires specialist care. Your treating doctor can interpret it alongside your medical history, previous results and any repeat tests. Severe breathlessness, chest pain, new confusion or inability to pass urine needs urgent emergency assessment rather than a routine appointment.
What does a kidney specialist do?
A nephrologist is a doctor who specialises in conditions that affect the kidneys. They can help identify the cause of kidney problems, interpret blood and urine tests, manage kidney disease and advise on protecting remaining kidney function. They also help manage problems such as difficult-to-control blood pressure and complications of reduced kidney function.
Your nephrologist may work with your primary-care doctor, diabetes specialist, dietitian or other healthcare professionals. Seeing a kidney specialist does not automatically mean you will need dialysis or a transplant.
When should you see a kidney specialist?
A referral depends on the whole clinical picture rather than one symptom or number. Your doctor may discuss a nephrology consultation in the following situations.
1. Your kidney function is reduced or declining
An estimated glomerular filtration rate, or eGFR, is calculated from a blood test and gives an indication of how well your kidneys filter blood. A lower eGFR or a decline over time may need further assessment. Your doctor will also consider urine results, other health conditions and previous measurements.
A sudden drop in kidney function may be caused by acute illness, dehydration, infection or another problem and may need prompt attention. Do not wait for months of repeat tests if your doctor suspects acute kidney injury.
Referral is often considered for advanced kidney impairment; it may be appropriate earlier when kidney function is falling quickly, the cause is unclear or other concerning findings are present. Your clinician can explain the timing that is right for you.
2. Your creatinine level is high
Creatinine is a waste product measured in a blood test. When kidneys filter less effectively, creatinine can rise, but the result can also be affected by other factors. One high value does not establish chronic kidney disease or tell you its cause.
Ask your doctor how the result compares with your earlier tests, what your eGFR is and whether a urine test or repeat blood test is needed. If the change is significant, persistent or unexplained, they may advise seeing a nephrologist.
3. You have protein or albumin in your urine
Albumin is a protein normally found in the blood. A urine albumin-to-creatinine ratio, or uACR, can identify albumin leakage, which may indicate kidney damage. An abnormal result sometimes needs to be repeated because temporary changes can occur.
Persistent or substantial albumin in urine, particularly alongside reduced kidney function or diabetes, may prompt a referral. Foamy urine can have several causes and cannot diagnose protein leakage by itself; a urine test is needed.
4. You have blood in your urine
Blood in urine can look pink, red or brown, or it may only be detected on a urine test. Possible causes include infection, stones and conditions affecting the kidneys or urinary tract. Even a small amount of visible blood should be assessed promptly.
Your doctor may recommend tests and refer you to a nephrologist, urologist or both depending on the suspected cause. Do not assume that blood in urine is harmless or that it always means kidney disease.
5. You have diabetes or high blood pressure with abnormal kidney tests
Diabetes and high blood pressure are common causes of chronic kidney disease. If you have either condition, regular follow-up helps detect problems before symptoms appear. A nephrologist may be helpful if kidney results worsen, urine albumin remains high or blood pressure is difficult to manage.
The US National Institute of Diabetes and Digestive and Kidney Diseases recommends annual kidney checks for people with diabetes. Ask your doctor which tests and schedule are appropriate for you, especially if you already have abnormal results.
6. You have persistent swelling or other concerning symptoms
Swelling in the feet, ankles, hands or around the eyes, changes in urination, ongoing fatigue or nausea can occur with kidney problems. These symptoms also have many other causes, so they require assessment rather than self-diagnosis.
Tell your doctor when symptoms started, whether they are changing and which medicines you take. New swelling with severe breathlessness, chest pain or confusion requires emergency care.
7. The cause of your kidney problem is unclear
A nephrologist may help when results are difficult to interpret or a specific kidney condition is suspected. Depending on your situation, the doctor may recommend additional blood or urine tests, an ultrasound or, in selected cases, a kidney biopsy. Not everyone needs all these tests.
If you have a family history of inherited kidney disease, previous acute kidney injury or another condition that may affect your kidneys, mention it during your consultation.
When is a kidney problem an emergency?
Seek immediate emergency assessment for severe breathlessness, chest pain, new confusion, fainting or an inability to pass urine. These symptoms can have several serious causes and should not wait for an outpatient nephrology appointment.
Seek prompt medical advice for a marked reduction in urine, visible blood in urine, worsening swelling, or fever with pain in your side or back, particularly if you are vomiting or feel very unwell. Your care team can decide how urgently you need assessment and whether hospital treatment is necessary.
Nephrologist vs urologist: which specialist should you see?
A nephrologist focuses on kidney function and medical management of kidney conditions. A urologist specialises in conditions of the urinary tract and male reproductive system and may perform procedures or surgery. For example, urinary obstruction or a kidney stone may involve urology, while kidney function problems may involve nephrology.
Some patients need both. Your primary-care doctor can guide you based on symptoms, examination and test results. If you are unsure, start by discussing your concern with a healthcare professional.
What happens at your first nephrology appointment?
The specialist will ask about your symptoms, medical history, diabetes or blood pressure, family history and medicines. They may review previous blood and urine tests, check your blood pressure and examine you for signs such as swelling.
You may discuss possible causes, whether the change appears sudden or long-standing, and whether additional testing is needed. Depending on the findings, your doctor may advise blood tests, urine tests or imaging. The goal is to understand your individual situation and agree on the next steps.
Which kidney tests might your doctor review?
Creatinine and eGFR
Creatinine is measured in blood and used to estimate eGFR. Your specialist will consider the trend over time as well as factors that may affect a result. A single abnormal test does not automatically confirm chronic kidney disease.
Urine albumin and urine analysis
A uACR checks for albumin leakage. Other urine tests can look for blood or signs of infection. A doctor may repeat an abnormal result and interpret it alongside your eGFR and health history.
Imaging and other tests
An ultrasound or other imaging may be used when the clinician needs to look at kidney size, structure or possible obstruction. In selected situations, a kidney biopsy may help clarify a diagnosis. Ask why a test is recommended and how its result will guide care.
How to prepare for a kidney specialist visit
Bring copies of recent and older blood tests, urine reports, imaging and discharge summaries if available. A record of results over time can be more useful than a single number. Bring a list of all prescription medicines, over-the-counter painkillers, vitamins and herbal supplements.
If you check blood pressure or blood sugar at home, take your readings with you. Write down symptoms, when they began and whether they are changing. You may find it helpful to bring a family member or friend to listen and take notes.
Questions to ask your nephrologist
You can ask: What do my eGFR, creatinine and urine albumin results mean? What might be causing the change? Do I need a repeat test or further investigation? Could my medicines affect my kidneys? What blood pressure or blood sugar target is right for me? Do I need specific food or fluid advice? When should I follow up, and which symptoms need urgent help?
Do not stop prescribed medicines, start supplements or make major dietary changes without discussing them with your care team. Some medicines can protect the kidneys when appropriately prescribed. Diet and fluid advice also vary depending on your condition and results.

Frequently asked questions
What is another name for a kidney specialist?
A kidney specialist is called a nephrologist. Nephrologists assess and manage medical conditions affecting the kidneys.
Does high creatinine always mean kidney failure?
No. Creatinine can rise for different reasons. Your doctor interprets it alongside eGFR, urine tests, earlier results and your medical history.
Can kidney disease occur without symptoms?
Yes. Early chronic kidney disease often has no obvious symptoms, which is why appropriate testing matters for people at risk.
Does seeing a nephrologist mean I need dialysis?
No. A nephrology visit can help identify a problem, monitor kidney function and plan treatment. Many patients do not need dialysis.
Should I see a nephrologist for blood in urine?
Visible blood in urine should be assessed promptly. Your doctor can determine whether a nephrologist, urologist or another specialist is appropriate.
What should I bring to the appointment?
Bring blood and urine results, previous reports, a medicine and supplement list, and any home blood pressure readings.
Can a nephrologist help with high blood pressure?
Yes. A nephrologist may help manage blood pressure, particularly when it is difficult to control or occurs with kidney disease.
Should I wait for a specialist if I cannot pass urine?
No. Inability to pass urine requires urgent assessment. Seek emergency care instead of waiting for a routine appointment.
