GFR With Cystatin C Serum (Adult - Above 18 Years)

• The GFR with Cystatin C Serum test is used to diagnose kidney disease and monitor kidney function in adults.
• It is particularly useful in cases where there is suspicion of kidney disease, such as in adults with a family history of kidney disease, or in adults with symptoms such as frequent urination, blood in the urine, or swelling of the legs and feet.
• The test is also useful in monitoring the effects of treatment for kidney disease and in determining the appropriate dosages of medications that are eliminated by the kidneys.

The GFR (Glomerular Filtration Rate) with Cystatin C Serum test estimates the GFR based on the level of cystatin C in the blood.

If the results of the GFR with Cystatin C Serum test are abnormal, it could indicate kidney disease or a decline in kidney function. Abnormal results may indicate that the kidneys are not functioning properly, and the severity of the abnormality can provide an indication of the extent of the kidney damage.

The test involves drawing a small amount of blood from a vein in your arm. A healthcare professional will clean the area with an antiseptic, wrap an elastic band around your upper arm to make the veins more visible, and insert a needle into a vein to collect the blood sample. You may feel a brief prick or stinging sensation when the needle is inserted, but the procedure is generally painless.

No special preparation is required for the test. However, it is recommended that you consult with your healthcare provider before taking the test, as they may have specific instructions or recommendations based on your individual medical history and current health status.

There are several symptoms or conditions that may call for a GFR (Glomerular Filtration Rate) with Cystatin C Serum test in adults above 18 years old. These may include:

• High blood pressure
• Diabetes
• Proteinuria
• Family history of kidney disease
• Use of medications that can damage the kidneys

There are several blood tests that may be ordered along with GFR with Cystatin C serum test:

• Creatinine test: Creatinine is a waste product produced by the muscles and is filtered out of the body by the kidneys. Creatinine levels in the blood are measured to assess kidney function.
• Blood urea nitrogen (BUN) test: BUN is another waste product that is filtered by the kidneys. BUN levels in the blood can indicate how well the kidneys are functioning.
• Urinalysis: A urinalysis can detect abnormalities in the urine, such as protein or blood, which can be an indication of kidney disease.
• Electrolyte panel: An electrolyte panel measures the levels of minerals such as sodium, potassium, and chloride in the blood. Abnormal levels can indicate kidney dysfunction.
• Complete blood count (CBC): A CBC measures the number of blood cells in the body. Abnormal levels can indicate kidney disease.
• Glucose test: A glucose test measures the level of sugar in the blood. Abnormal levels can indicate diabetes, which can lead to kidney disease
