Renal Function

Renal function tests show how well your kidneys filter waste, balance fluids and minerals, and help control blood pressure and bone health. Because early kidney problems are often silent, routine blood and urine testing can find issues before symptoms start—especially if you have diabetes, high blood pressure, heart disease, a family history of kidney failure, or a history of urinary problems or stones.

A proactive plan begins with a renal function (kidney) panel—creatinine with estimated glomerular filtration rate (eGFR), blood urea nitrogen (BUN), electrolytes (sodium, potassium, chloride), and bicarbonate/CO2—and often includes calcium and phosphorus. Add cystatin C to refine eGFR, and pair blood tests with urine albumin-to-creatinine ratio (ACR) and urinalysis to check for kidney damage. These labs support screening, diagnosis, staging, and monitoring, but they do not replace a clinician’s evaluation or imaging when needed.

Signs, Symptoms & Related Situations

  • Often silent early: abnormal labs on a routine check

  • Urinary clues: foamy urine (protein), blood in urine, frequent nighttime urination, burning/urgency (UTI signs)

  • Whole-body: ankle/leg swelling, fatigue, poor appetite, nausea, itchy skin, high blood pressure

  • Risk contexts: diabetes, hypertension, cardiovascular disease, obesity, kidney stones, recurrent UTIs, autoimmune disease, long-term NSAID use, family history of kidney failure

  • Seek urgent care now: chest pain, severe shortness of breath, confusion, little or no urine, severe flank pain, or rapidly worsening swelling

All symptoms and risks should be reviewed by a qualified clinician.

Why These Tests Matter

What testing can do

  • Detect kidney problems early and stage chronic kidney disease (CKD) using eGFR and ACR

  • Differentiate causes (e.g., dehydration/acute kidney injury vs. chronic disease) by combining renal panel results with urinalysis and targeted add-ons

  • Monitor complications such as electrolyte shifts, metabolic acidosis (low bicarbonate), and bone-mineralimbalances (calcium/phosphorus)

What testing cannot do

  • Identify the exact cause in every case—some situations need imaging, serologies, or biopsy

  • Replace blood-pressure/diabetes management or medication review

  • Provide treatment or dosing advice—use results to plan with your clinician

What These Tests Measure (at a glance)

  • Creatinine & eGFR: core measure of filtration. eGFR <60 for ≥3 months suggests CKD; trends matter more than one value.

  • Cystatin C (± eGFRcys): confirms/refines eGFR when creatinine is borderline or muscle mass is unusual.

  • BUN: waste product that rises with reduced kidney function or dehydration—interpret with creatinine and history.

  • Electrolytes:

    • Sodium (Na?): fluid balance; abnormal values can reflect hydration or hormonal issues.

    • Potassium (K?): high levels can be dangerous in kidney disease; low levels may occur with losses or certain medicines.

    • Chloride (Cl?) & Bicarbonate/CO2: help assess acid–base status; low CO2 suggests metabolic acidosis.

  • Calcium & Phosphorus: important for bone-mineral balance; often shift in CKD.

  • Anion Gap (calculated): helps classify metabolic acidosis types.

  • Urine Albumin-to-Creatinine Ratio (ACR): detects albumin leakage (A1 <30, A2 30–299, A3 ≥300?mg/g).

  • Urinalysis with Microscopy: blood, protein, glucose, casts (RBC casts suggest glomerular disease), crystals (stone risk), infection clues.

  • Optional context tests: Magnesium, uric acid, serum/urine osmolality, urine sodium (for select acute evaluations).

How the Testing Process Works

  1. Select your starting set: most people begin with a renal function panel, urine ACR, and urinalysis.

  2. Provide samples: clean-catch urine and a standard blood draw; no fasting unless lipids/glucose are included.

  3. Confirm persistence: repeat eGFR/ACR over ≥3 months to confirm CKD vs. temporary changes.

  4. Broaden if needed: add cystatin C, bone-mineral markers, anemia/iron studies, or stone/UTI tests based on findings.

  5. Review & plan: discuss results with your clinician; imaging or specialist referral may be recommended.

Interpreting Results (General Guidance)

  • eGFR: generally normal at ≥90; <60 for ≥3 months supports CKD. Falling trends raise concern.

  • ACR: A1 (<30?mg/g) normal-mild; A2 (30–299) moderate; A3 (≥300) severe—higher categories increase risk at any eGFR.

  • BUN/Creatinine pattern: both high may reflect reduced filtration; BUN-predominant elevations can occur with dehydration or high protein intake.

  • Potassium: elevated K? can be urgent in CKD; low K? may occur with losses or certain medicines—always interpret with a clinician.

  • Bicarbonate/CO2: low CO2 suggests metabolic acidosis, common in advanced CKD.

  • Calcium/Phosphorus: abnormal patterns point toward bone-mineral imbalance.

  • Urinalysis clues: RBC casts/dysmorphic RBCs suggest glomerular disease; nitrite/leukocyte esterase favor infection; crystals suggest stones.
    Always interpret patterns over time with a qualified healthcare professional.

Choosing Panels vs. Individual Tests

  • Foundational kidney panel: eGFR (creatinine) • BUN • Na/K/Cl • CO2 • Calcium/Phosphorus

  • Refinement/confirmation: Cystatin C eGFR when creatinine-based eGFR is borderline or muscle mass is atypical.

  • Damage detection: Urine ACR and urinalysis to uncover albumin/protein or blood in urine.

  • Complication checks: Electrolytes/CO2, PTH/25-OH Vitamin D, CBC/Iron studies, uric acid as clinically indicated.

FAQs

Do I need to fast for a renal function panel?
No. Fast only if your order includes lipids or fasting glucose.

Why would I add cystatin C?
It can confirm or refine eGFR, especially when creatinine is borderline or muscle mass is unusual.

How often should I test if I have diabetes or high blood pressure?
Often yearly for eGFR, ACR, and urinalysis; more often if abnormal or high-risk.

Can dehydration change my results?
Yes. Dehydration can raise BUN and affect creatinine and ACR. Rehydration and repeat testing may be needed.

What if my potassium is high?
High K? can be serious. Contact your clinician promptly—do not make changes without medical advice.

Is a normal eGFR enough to clear me?
Not always. ACR and urinalysis can detect kidney damage even when eGFR looks normal.

When should I see a kidney specialist?
Consider referral for eGFR <30, A3 albuminuria, rapid decline, resistant hypertension, or unclear cause—your clinician will guide you.

Everything About Renal Function Decline and Lab Tests

An estimated 37 million people in the United States have kidney disease, and 1 out of 2 people have impaired renal function and don't even realize that they do.

For this reason, renal function lab tests are crucial in managing your overall kidney health. And if you're at risk for developing kidney disease, you need as much knowledge as possible. A renal function panel is a perfect way to start.

Sometimes your kidneys can fail, and your renal function declines. It's essential to have the education and tools you need to manage your kidney health. Keep reading this guide to learn everything you need to know about kidney decline and renal function tests.

What is Renal Function Decline?

Your kidneys are amazing organs, and they work hard to keep the balance of your body in check. They maintain a balance in the body by regulating water and minerals like sodium and potassium. Your kidneys are also responsible for removing waste from your blood after digestion, medication, or chemical exposure.

Your kidneys are even responsible for making chemicals to help with red blood cell production, along with vitamin D.

Renal function decline is the gradual loss of your kidney function, either from disease or other factors. When you have kidney disease, it affects your body's ability to clean and filter your blood. 

When your kidneys get damaged, waste products build up in your blood, causing symptoms of kidney failure.

The main types of kidney disease are acute and chronic kidney disease. Both acute and chronic diseases have different causes, from injury to illness.

Acute Kidney Disease

If your kidneys stop working suddenly, it's called an acute renal failure or acute kidney injury. The leading causes of acute kidney failure include:

  • Decrease in blood flow to the kidneys
  • Damage to the kidneys
  • Urine that is backed up in the kidney

Most often, acute kidney failure is caused by blood loss from a traumatic injury, dehydration, severe infection, taking certain medications, or complications from pregnancy.

People with autoimmune disease, heart, or liver failure are more likely to develop acute kidney failure.

Chronic Kidney Disease

Doctors will classify this as chronic kidney disease if your kidneys don't function normally for three months or more. Often you don't have any symptoms in the early stages of the disease, but this is also when it's much easier to treat. 

The most common conditions over time that harm your kidneys are diabetes and high blood pressure. Other conditions that can cause kidney failure and kidney disease include:

  • Autoimmune diseases like lupus
  • Viral illnesses like HIV, AIDS, and hepatitis B and C
  • Kidney infection or a urinary tract infection that leads to kidney damage
  • Inflammation in the glomeruli (tiny filters) in your kidneys
  • Polycystic kidney disease is genetic and causes fluid-filled sacs on your kidneys

If you have kidney abnormalities at birth, they block your urinary tract and affect kidney function. Toxins, drugs, and long-term use of ibuprofen or any anti-inflammatory drug can cause kidney damage over time.

Kidney Cancer

Another thing that causes kidney function decline is kidney cancer. The most common type of kidney cancer is renal cell carcinoma. Children can also develop a type of kidney cancer called Wilms' tumor.

Kidney cancer is thought to have a genetic cause, but if you have long-term dialysis for kidney failure, you're at greater risk for developing kidney cancer overall.

Risk factors for Renal Function Decline

Your most significant risk factors for a decline in renal function include diabetes and high blood pressure, but there are other risk factors including:

  • Genetics. Having immediate family members with kidney disease increases your risk.
  • Being over 60 years old
  • Being African American, Hispanic, Native American, or Asian American

Causes of Renal Function Decline

Diabetes and high blood pressure are not only your biggest risk factors. They are also the biggest causes of renal function decline. Other conditions that can cause kidney failure ad kidney disease include:

  • Polycystic kidney disease
  • Glomerulonephritis
  • An acute kidney injury that causes kidney damage
  • Autoimmune diseases
  • Kidney cancer

Signs and Symptoms of Renal Function Decline

Your kidneys can adapt and compensate for a long time before you get symptoms of kidney disease. Most of the time, kidney damage happens so slowly that you won't feel any symptoms until the advanced stages. Symptoms you'll notice include:

  • High blood pressure
  • Loss of appetite
  • Weakness and fatigue
  • Nausea and vomiting
  • Metallic tase
  • Trouble concentrating
  • Trouble sleeping
  • Muscle cramps
  • Swelling in your feet, ankles, or legs
  • Chest pain and shortness of breath
  • Itching

How Is a Decline In Renal Function Diagnosed?

Your first step towards a diagnosis is making an appointment with your doctor to discuss your symptoms and medical and family history. 

Your doctor will perform a physical exam and check for problems with your heart or high blood pressure. Your doctor will also likely order blood tests and a urine test to assess your kidney function.

Depending on what your initial tests show, you may also have to have imaging tests to look at your kidneys or a kidney biopsy of a piece of your kidney tissue to determine what's causing your problems.

Lab Tests to Monitor Renal Function

The best test to evaluate and monitor your renal function is a renal function panel. This panel measures your BUN/Creatinine Ratio, which helps determine your kidney function and what conditions may be causing a decrease in blood flow to the kidneys. A renal function panel also checks your glucose, calcium, and electrolyte levels.

Another test helpful in screening and monitoring a known or suspected kidney disease is the cystatin C with eGFR test. Cystatin C is a small protein found throughout your body and filtered from the blood by your kidneys. This test measures the amount of cystatin in your body.

High protein concentrations in your urine are a sign of kidney disease. A protein total and random urine with creatinine test measure the amount of protein present.

A complete blood count (CBC) is also important as it measures your red blood cells and the overall health of your blood.

FAQS about Renal Function

Are you wondering how you know if you have kidney disease? Since there are often no signs or symptoms initially, it's essential to have both blood and urine tests to check.

How can you protect your kidneys in the best way? The best way to protect your kidneys is to evaluate your lifestyle habits and make the changes you need. Stop smoking, keep your blood sugar in range if you have diabetes, and focus on a healthy diet and exercise.

What type of doctor specializes in treating kidney problems? A nephrologist will treat you if you've been diagnosed with kidney disease.
