eGFR or estimated glomerular filtration rate and creatinine are two important indicators of kidney function. While an individual test result does not always give complete information on kidney health and function, these numbers can help physicians discover possible kidney issues, monitor existing conditions, and determine whether further testing is required.
Creatinine is a waste product that is produced as by-product by muscles and flows out of the blood due to kidney function. If kidney function worsens, creatinine is accumulated in the bloodstream. However, apart from that, creatinine levels can depend on other factors, such as age, amount of muscle mass, diet, dehydration, and the use of certain medications. That is why doctors often use creatinine along with eGFR, instead of evaluating creatinine alone.
eGFR Levels and What They Mean
eGFR measures the efficiency of blood filtration by the kidneys. To calculate eGFR, several factors are required, including blood creatinine, age, and sex. In general, the higher the eGFR level, the better is the efficiency of kidney filtration; however, it is still necessary to evaluate the results.
If an eGFR score is greater than or equal to 90, it is considered normal or high in the absence of kidney injury. If the score ranges between 60 and 89, the kidney function could be considered mildly impaired, although this does not automatically mean the presence of chronic kidney disease. Nitesh Kumar also emphasizes that it is relevant to check for other abnormalities that point to kidney malfunction, for example, protein or albumin in urine.
If an eGFR score is under 60 for more than three months, this indicates the existence of chronic kidney disease. If it goes below 30, severe kidney impairment takes place and requires careful monitoring.
Understanding eGFR Changes Over Time
Why eGFR Can Change
The eGFR result for an individual may change due to short-term conditions like dehydration, sickness, use of medication or creatinine fluctuation. Hence, one abnormal reading cannot be taken as a sign of permanent kidney damage. Doctors always consider past readings while interpreting current values.
In case of a progressive decrease in eGFR, physicians might advise further tests such as urine albumin-creatinine ratio, blood pressure measurement, blood analysis, or kidney imageries.
Early diagnosis becomes essential in case of subjects diagnosed with diabetes, high blood pressure, cardiovascular disease, or having kidney disease running the family.
When Should You See a Kidney Specialist?
Individuals can find consulting a nephrologist useful in case of persistent decline in kidney functioning,presence of high levels of protein in urine or blood, problems with hypertension, or any sudden fluctuations in kidney function. While choosing a kidney Specialist in Patna, people should ensure that their choice is made based on the fact that the expert analyzes notjust lab results or medical history but also medications, symptoms, and risk factors.
They may come across the name Nitesh Kumar while searching for kidney specialists. However, choosing the right professional should be based on qualifications and experience rather than just its popularity.
eGFR and Creatinine: The Bigger Picture
The eGFR and creatinine results must be interpreted together. Broadly similar creatinine levels can produce widely different eGFR results since many variables determine kidney function. In the same vein, mildly abnormal results can mean different things depending on whether they are new, old, or accompanied by other abnormalities.
If you’ve undergone a kidney test recently and gotten abnormal results, do not panic, and make any change in medication, or diet without consulting your doctor. If you need to consult the Best Nephrologist in Patna, your consultation will help you understand your results and determine if any further testing or treatment is needed.
gEF and creatinine readings should be understood as the major steps to gain better knowledge of kidney function. Regular checkups, good management of blood pressure and blood sugar, and proper hydration routine will help keep kidneys in good shape.
