Below are the key blood tests used to assess kidney health, each focusing on a specific hormone or indicator. Please confirm the package you are looking for.
Creatinine is a waste product from muscle metabolism, filtered by the kidneys. Measuring blood creatinine levels helps assess kidney function—high levels suggest impaired kidney filtration or kidney disease, while normal levels indicate healthy renal function.
Potassium is a key electrolyte that helps regulate nerve signals, muscle contractions, and heart function. Blood potassium levels must be balanced—high (hyperkalemia) or low (hypokalemia) levels can cause serious heart and muscle problems.
Urea is a waste product formed from protein metabolism, filtered by the kidneys. Measuring blood urea levels helps assess kidney function and hydration status. Elevated urea may indicate kidney impairment, dehydration, or high protein breakdown.
The Estimated Glomerular Filtration Rate (eGFR) measures how well the kidneys filter waste from the blood. It’s calculated using creatinine levels, age, sex, and race. A low eGFR indicates impaired kidney function or chronic kidney disease.
Sodium is a vital electrolyte that helps maintain fluid balance, nerve function, and muscle contractions. Abnormal blood sodium levels—too high (hypernatremia) or too low (hyponatremia)—can cause dehydration, confusion, or seizures.
Uric acid is a waste product from purine metabolism. High levels can cause gout and kidney stones, while low levels are less common but may occur with certain diseases. Measuring uric acid helps diagnose and monitor these conditions.

A kidney health blood test is a medical test that measures specific biomarkers in your blood to assess how well your kidneys are functioning. These tests help detect early signs of kidney disease, monitor existing conditions, and guide treatment to prevent further kidney damage.
Key blood tests for assessing kidney health include the creatinine test, blood urea nitrogen (BUN) test, glomerular filtration rate (GFR), and electrolyte levels such as potassium and sodium. These tests evaluate how well your kidneys are filtering waste and maintaining a healthy balance of minerals in your blood.
The creatinine test measures the level of creatinine, a waste product produced by muscle metabolism, in your blood. Elevated creatinine levels can indicate that your kidneys are not filtering waste efficiently, which may be a sign of kidney dysfunction or disease.
The glomerular filtration rate (GFR) is a calculation based on your creatinine levels, age, sex, and body size that estimates how well your kidneys are filtering blood. A low GFR indicates reduced kidney function and is a critical marker for diagnosing and staging chronic kidney disease (CKD).
Blood tests can detect early kidney disease by identifying abnormal levels of waste products like creatinine and urea in the blood, as well as changes in electrolyte levels. Early detection allows for timely interventions to slow or prevent the progression of kidney disease.
It's recommended to get a kidney health blood test annually if you have risk factors like high blood pressure, diabetes, or a family history of kidney disease. Individuals with existing kidney conditions may need more frequent testing as advised by their healthcare provider.
The blood urea nitrogen (BUN) test measures the amount of urea nitrogen, a waste product formed in the liver, in your blood. High BUN levels can indicate impaired kidney function, as the kidneys may not be effectively removing urea from the bloodstream.
Yes, blood tests are essential for managing chronic kidney disease (CKD). Regular monitoring of creatinine, GFR, and electrolyte levels helps track the progression of CKD and guides treatment decisions to prevent further kidney damage and manage complications.
If your kidney health blood test shows abnormal results, consult your healthcare provider for further evaluation. They may recommend additional tests, lifestyle changes, medications, or referrals to a nephrologist to manage your kidney health and prevent complications.
Yes, kidney health blood tests are necessary even if you don't have symptoms, as kidney disease often progresses silently without noticeable symptoms in the early stages. Regular testing can detect issues early, allowing for timely intervention to protect your kidney function.
