Overall, Kidney Assessment: What's Included in a Kidney Test Packag


Did you know that over 800 million people are living with kidney disease, and most of them don't even know it? Are you one of those millions unaware of your kidney health? Kidney tests are crucial for assessing their function and detecting potential issues early on. 

In this blog, we'll delve into kidney health and explore what's included in a comprehensive kidney test package

Understanding Kidney Function

Understanding the basic function of your kidneys is crucial before delving into the specifics of kidney tests. 

Your kidneys act as a natural filtration system in your body. They filter your blood, removing waste products, excess fluids, and electrolytes. Additionally, they maintain a healthy balance of essential substances such as sodium and potassium. Kidneys produce hormones that regulate blood pressure, red blood cell production, and calcium metabolism. Any malfunction in these vital organs can greatly impact your overall health.

Components of a Kidney Test Package

When you undergo kidney tests, blood and urine analyses are usually conducted. These tests offer important information about your kidney function and overall health.

Blood Test for Kidney

Here's what blood test for kidneys measure:

1. Glomerular Filtration Rate (GFR): GFR is a crucial measure used to evaluate the efficiency of your kidneys in filtering waste from your blood. It is expressed in milliliters per minute per 1.73 square meters and indicates how well your kidneys are functioning. Typically, normal GFR values fall between 90 to 120 mL/min/1.73 m². Lower values indicate impaired kidney function.


The results of GFR are categorized into different stages of kidney disease:


  • Stage 1: GFR ≥ 90 (normal kidney function)
  • Stage 2: GFR 60-89 (mildly decreased kidney function)
  • Stage 3: GFR 30-59 (moderately decreased kidney function)
  • Stage 4: GFR 15-29 (severely decreased kidney function)
  • Stage 5: GFR < 15 (kidney failure)


By assessing your GFR score, you can gain insights into the severity of any existing kidney disease or dysfunction you may have.

2. Creatinine Levels: Creatinine is a waste product that results from muscle metabolism. In a healthy person, the kidneys effectively filter out any excess creatinine, maintaining stable levels in the blood. However, elevated levels of creatinine may suggest impaired kidney function since the kidneys might not be efficiently removing this waste product. It's important to note that normal creatinine levels can vary depending on age, sex, and individual muscle mass.

3. Blood Urea Nitrogen (BUN): BUN is a blood test measuring urea nitrogen. Urea is a waste product produced when the liver breaks down protein. Elevated BUN levels may indicate problems with kidney or liver function or dehydration.

Urine Analysis

  1. Specific Gravity: Measuring specific gravity is a way to determine the concentration of urine and provide insights into hydration levels and waste product concentration. A low specific gravity might signify overhydration, whereas high values would indicate dehydration or potential kidney issues.
  2. Proteinuria: Proteinuria refers to the presence of an excess amount of protein in the urine. Normally, the kidneys filter waste products while keeping essential proteins in the bloodstream. When protein is found in urine, it can indicate early signs of kidney damage or other health conditions.
  3. Hematuria: Hematuria refers to the presence of blood in the urine. Various factors can cause this condition, including kidney problems, urinary tract infections, or underlying medical conditions. If blood is detected in the urine through a urine analysis, it may indicate the need for additional investigation into determining the root cause of this issue.
  4. pH Levels: Monitoring the pH level of your urine can offer valuable information about your kidney health and acid-base balance. If your pH level consistently falls outside the normal range, it may indicate an underlying urinary tract issue or kidney condition that requires further attention.

What Each Test Reveals About Kidney Function

To accurately interpret your results and evaluate your kidney function, it is essential to understand the meaning behind each of these kidney tests.

GFR and Creatinine Levels

GFR and creatinine levels are closely linked and serve as crucial indicators of kidney function. Let's explore what these measurements disclose:


  1. Identifying Kidney Disease: If your estimated glomerular filtration rate (GFR) remains below 60 mL/min/1.73 m² for three months or more, it may indicate the presence of chronic kidney disease. Additionally, elevated levels of creatinine frequently coincide with decreased GFR, suggesting potential difficulties in adequately filtering waste products by the kidneys.
  2. Determining Kidney Function: The best way to assess overall kidney function is through the Glomerular Filtration Rate (GFR). As GFR decreases, it indicates a higher severity of kidney disease. Creatinine levels can provide further information about kidney health and support GFR findings.

Blood Urea Nitrogen (BUN)

BUN levels can provide valuable information about the functioning of both the kidneys and liver, as well as indicate hydration status.


  1. Assessing Kidney and Liver Function: An elevated BUN level may be a sign of kidney or liver problems. Healthcare professionals will analyze additional test results and consider symptoms to determine the underlying cause.
  2. Detecting Dehydration and Kidney Disease: Interpreting BUN results requires considering various factors, including dehydration and medication usage.

Urine Analysis

Urine analysis can reveal various aspects of kidney and urinary tract health:


  1. Specific Gravity: The specific gravity of a substance can provide important information about hydration levels and potential kidney issues. A low specific gravity may indicate overhydration, which can be problematic in certain circumstances. Conversely, a high specific gravity could point towards dehydration or potential kidney problems.
  2. Proteinuria: Proteinuria, which is the presence of an abnormally high amount of protein in urine, indicates potential kidney damage. This can be associated with other health issues such as diabetes or high blood pressure.
  3. Hematuria: If blood is detected in the urine, it is important to investigate further as it could be a sign of kidney problems or issues with the urinary tract. Identifying the underlying cause is crucial.
  4. pH Levels: Monitoring pH levels can provide valuable information about acid-base imbalances and urinary tract issues. By keeping track of pH, it becomes possible to detect potential kidney-related concerns.

Kidney Tests and Overall Well-Being

It is crucial to regularly undergo kidney testing as part of maintaining your overall well-being. Here's why these tests are significant:

Importance of Early Detection

Kidney diseases often develop silently, without obvious symptoms, until they reach an advanced stage. Regular kidney tests can catch problems early, enabling prompt intervention and treatment.

Preventive Measures for Kidney Health

Taking care of your kidneys and maintaining their health is crucial. Here are a few important steps you can take: 


  1. Stay hydrated by drinking enough water throughout the day.
  2. Follow a balanced diet that includes fruits, vegetables, whole grains, and lean proteins. Avoid high-sodium and processed foods.
  3. Control your blood pressure and blood sugar levels since uncontrolled hypertension and diabetes can negatively impact kidney function. 

Lifestyle Changes to Improve Kidney Function

If your healthcare provider identifies kidney problems, they may suggest making lifestyle changes or taking medications to slow down the progression of the disease. Taking early action can help prevent additional damage to the kidneys.

Discussing Results with a Healthcare Professional

It is crucial to understand the results of your kidney tests. If you receive abnormal results, consult with a healthcare professional who can offer guidance and develop a personalized care plan for you.


Taking care of your kidneys is crucial for maintaining good overall health. Regular kidney testing plays a vital role in assessing and preserving kidney function. This comprehensive package includes blood tests to measure GFR, creatinine, and BUN levels, as well as urine analysis.
