Know more about this test

The GFR With Cystatin C, Serum -18 Years & Above is a blood test tailored for individuals above 18 years to see how well your kidneys are functioning. It measures the levels of cystatin C (a protein in blood) and estimates the filtration rate of the kidneys. It is a sensitive test that is not affected much by non-renal factors such as age, gender, muscle mass or diet. This test is available at an affordable price in Bangalore with Tata 1mg labs.

The GFR With Cystatin C, Serum -18 Years & Above test helps in the early detection of kidney disease, monitoring disease progression and assessing kidney function in predisposed populations (e.g.,elderly, obese, or those with muscle-atrophy). It is recommended when a past kidney function test results show unclear results about your kidneys and your doctor wants to check again with the GFR With Cystatin C, Serum -18 Years & Above test to be sure. Also, it can be done when you are older and have lots of muscle (like a bodybuilder) where creatinine levels can vary. 

No special preparation is required for the GFR With Cystatin C, Serum -18 Years & Above. Eat and drink as per your daily routine.

Understanding GFR With Cystatin C, Serum -18 Years & Above

Glomerular Filtration Rate (GFR) is a biomarker of kidney function which helps assess the ability of the kidneys to filter waste and excess fluids from the body. Conventional GFR estimation relies on serum creatinine levels, which has certain limitations particularly for individuals with advanced age or varying muscle size. On the other hand, Cystatin C, a protein expressed in all nucleated cells and due to its relatively constant rate of generation, it is considered as the reliable marker for assessing kidney function. This protein is freely filtered by the kidneys and not significantly affected by the factors like age, gender, muscle mass or diet, its serum levels provide a more accurate measurement of GFR. 

The GFR With Cystatin C, Serum -18 Years & Above test helps in the early detection of kidney disease, monitoring disease progression and assessing kidney function in predisposed populations (e.g., elderly, obese, or those with muscle-atrophy). It is recommended when a past kidney function test results show unclear results about your kidneys and your doctor wants to check again with the GFR With Cystatin C, Serum -18 Years & Above test to be sure. This test provides more accurate estimates in patients with differences in diet, extremes of muscle mass (such as body builders or patients with muscle wasting), in estimating change in eGFR over time in people with changing muscle mass or diet. 

Cystatin C based GFR estimation is useful in various conditions, including Chronic Kidney Disease (CKD) diagnosis and staging, Acute kidney disease (AKI) assessment, End-stage Renal Disease (ESRD) evaluation, Diagnosis of nephrotic syndrome and Glomerulonephritis. Moreover, it helps in monitoring kidney function in individuals with comorbidities like diabetes, hypertension, cardiovascular disease, liver disease etc. 

No special preparation is required for this test. Inform your doctor about all the medications or supplements that you may be taking as well as your medical history as these factors could potentially affect the test results.  

Lab test results may vary across laboratories. Interpretation of the test results requires expert guidance. Therefore, do not self-medicate and talk to your doctor to understand your test results correctly. The insights from GFR With Cystatin C, Serum -18 Years & Above test helps doctors determine your medical condition, make recommendations for lifestyle modifications such as diet and exercise, prescribe medication if required to manage your condition, and formulate your overall treatment plan.

What does GFR With Cystatin C, Serum -18 Years & Above measure?

Contains 3 tests

The GFR With Cystatin C, Serum -18 Years & Above test assesses two key parameters of kidney function: serum creatinine and cystatin C levels along with eGFR by Cystatin C. Serum creatinine reflects muscle metabolism and how well the kidneys are filtering waste, while cystatin C, is a low-molecular weight  protein that is produced by body cells and excreted by the kidneys by glomerular filtration and provides an alternative measure of kidney filtration that is less affected by age, gender, muscle mass and diet. The resulting eGFR gives a more comprehensive picture of kidney health, helping to identify abnormalities in kidney function and guide appropriate clinical decisions.

By integrating the information from the GFR With Cystatin C, Serum -18 Years & Above, doctors can obtain a clearer understanding of an individual’s kidney function and the potential implications for their overall health.

The Serum Creatinine test measures the creatinine level, a byproduct produced by the wear and tear of muscles during energy production. Since kidneys help filter creatinine, this test helps determine how well your kidneys work. Usually, high levels of creatinine in the blood signal diminished kidney function. At the same time, low levels may indicate decreased muscle mass.

The Cystatin C test measures the amount of cystatin C. It is a protein produced by all nucleated cells in the body. The kidneys filter cystatin C from the blood. Its level in the blood can help estimate the glomerular filtration rate (GFR), a key indicator of kidney health. Higher than normal levels of cystatin C suggest that the kidneys are not filtering the protein efficiently. This indicates potential kidney dysfunction. This test is more sensitive than creatinine for detecting early kidney disease. It is especially useful for patients with unusual body types (such as those who are malnourished, practice a vegetarian diet, have amputated limbs, or have reduced muscle mass) or those at higher risk for kidney problems.

The eGFR by Cystatin C test measures the estimated glomerular filtration rate (eGFR), which is an indicator of kidney function. Unlike the traditional eGFR test that relies on creatinine levels, this test uses cystatin C, a protein produced by cells throughout the body, to assess kidney function more accurately, especially in individuals with muscle mass abnormalities or those with extreme body weights. Abnormal levels of cystatin C can indicate kidney impairment, as the kidneys are responsible for filtering this protein from the blood. The eGFR value helps doctors determine the degree of kidney function and stage of chronic kidney disease (CKD). By integrating the information from the GFR With Cystatin C, this test provides a clearer picture of kidney health. It helps detect kidney problems earlier and allows doctors to make better decisions for managing and treating kidney conditions.

FAQs related to GFR With Cystatin C, Serum -18 Years & Above in Bangalore

The GFR With Cystatin C, Serum -18 Years & Above test measures serum creatinine and cystatin C levels in the blood to estimate the glomerular filtration rate (eGFR). This helps assess kidney function and detect potential kidney disorders.
This test is crucial for evaluating how well your kidneys are filtering waste from the blood. It is particularly useful for individuals at risk of kidney disease, such as those with diabetes, hypertension, or a family history of kidney problems.
A phlebotomist (a trained professional to perform blood draws) will clean your skin using an antiseptic alcohol cotton swab or wipe and take blood samples from your vein using a needle. The blood sample will be stored safely and transported to the laboratory for analysis.
No fasting is required before the GFR With Cystatin C, Serum -18 Years & Above test. However, inform your doctor about any medications or supplements you are taking, as some may affect the results.
