Kidney Checks include Urea, EGFR, Creatinine, albumin, sodium total protein, Globulin
Customize TestA kidney blood work panel evaluates how effectively your kidneys filter waste and maintain fluid balance. Clinicians use markers such as serum creatinine, cystatin c, and the estimated glomerular filtration rate to assess kidney filtration rate and detect early dysfunction.
This assessment is commonly referred to as an rft blood test or rft test and may also be ordered as part of a kidney profile or urea and electrolytes blood test.
A comprehensive kidney disease blood test typically includes:
Creatinine test
Urea and electrolytes test
Serum urea level
U and e blood test parameters
Estimated gfr blood test values
The glomerular filtration rate blood test estimates how much blood your kidneys filter each minute. Laboratories calculate gfr estimated values using serum creatinine and validated equations. Some panels also measure cystatin c to improve accuracy when creatinine high level results may not reflect true function.

All refer to assessment of kidney filtration capacity.
Egfr levels indicate overall kidney function.
Egfr of 90 or glomerular filtration rate 90 generally reflects normal kidney filtration rate in adults without additional abnormalities.
Lower egfr range values may indicate gfr kidney disease or gfr and kidney disease progression.
Persistent reduction supports diagnosis of kidney disease and may indicate need for test for chronic kidney disease confirmation.
Clinicians interpret egfr results in combination with clinical history, urine findings, and kidney disease creatinine levels.
The creatinine test measures waste produced by muscle metabolism. Serum creatinine high or creatinine high findings suggest reduced filtration efficiency.
High urea and creatinine may indicate impaired renal clearance, dehydration, or other metabolic stressors. A urea and creatinine test helps clarify whether abnormalities are acute or chronic.
Urea and electrolytes testing also evaluates sodium, potassium, and other electrolytes to detect complications of gfr in chronic kidney disease.
Doctors may recommend kidney blood work if you have:
Diabetes
Hypertension
Family history of kidney disease
Abnormal routine labs
Symptoms such as swelling, fatigue, or changes in urination
Egfr blood testing plays a central role in early detection because chronic kidney disease often develops without obvious symptoms.
Healthcare providers use estimated glomerular filtration rate results to:
Stage chronic kidney disease
Adjust medication dosing
Monitor progression
Evaluate response to treatment
A declining gfr rate requires structured follow up. Stable egfr of 90 without proteinuria typically requires routine monitoring only.
Clinicians follow evidence based protocols for rft blood test interpretation.
Best practice includes:
Confirming abnormal egfr results with repeat testing
Reviewing medications that may affect serum creatinine
Correlating laboratory data with clinical assessment
Avoiding over interpretation of a single isolated result
Testing services such as Medichecks may provide direct to consumer access, but medical review remains essential for accurate diagnosis of kidney disease.
Gfr glomerular filtration rate refers to the actual filtration process. Egfr medical calculations estimate this value using blood markers such as serum creatinine or cystatin c.
An egfr of 90 or glomerular filtration rate 90 usually indicates normal kidney function if no other abnormalities are present.
Creatinine high level findings may suggest impaired kidney filtration rate, but doctors confirm diagnosis of kidney disease using repeat tests and clinical evaluation.
A kidney profile commonly includes creatinine test, urea electrolytes test, serum urea level, and estimated glomerular filtration rate.
Diagnosis relies on persistent reduction in egfr range values, abnormal urine findings, and clinical assessment over time.

Urea is a waste product it is produced as your body digests protein and is carried by the blood to your kidneys, which filter the urea out of the blood and into urine.
This test looks at how well your kidneys are functioning.
High urea levels suggest poor kidney function. This may be due to acute or chronic kidney disease. However, there are many things besides kidney disease that can affect urea levels such as stress, recent heart attack or severe burns; bleeding from the gastrointestinal tract; conditions that cause obstruction of urine flow or dehydration.
Low urea levels are not common and are not usually a cause for concern. They can be with low protein diets, excess hydration malnutrition or liver failure. Low urea levels are also seen in normal pregnancy.
Creatinine is a chemical byproduct molecule generated from muscle metabolism.
Measuring Creatinine is an accurate marker of your kidney function.
Higher than usual levels of Creatinine can be caused by a high intake of Creatinine supplements, animal protein and vigorous exercise however it can also mean that your kidneys are not functioning properly.
Lower Creatinine levels can usually be caused by a reduction in muscle mass, low protein diet. It can also be an indication that your kidneys are not functioning correctly.
The estimated glomerular filtration rate (eGFR) assesses how well the kidneys are working by estimating the amount of blood filtered through the kidneys. The glomeruli are tiny filters in the kidneys responsible for removing waste products. If these filters do not do their job properly, kidney function can be impaired. The eGFR calculation is an estimate of actual glomerular filtration rate, calculated using your age, gender, ethnicity, and serum creatinine levels.
