GFR With Creatinine

• The primary purpose of the test is to evaluate how well the kidneys are filtering waste from the blood.
• It is employed in diagnosing and monitoring conditions such as chronic kidney disease (CKD) and acute kidney injury (AKI).
• For patients taking medications that can impact kidney function, the test helps healthcare providers adjust dosages to prevent adverse effects.
• In certain cases, the test may be ordered before surgical procedures to ensure the kidneys can handle the stress of anesthesia and surgery.
• Monitoring GFR can aid in assessing the risk of developing kidney-related complications, including cardiovascular disease.

The test measures the glomerular filtration rate along with Creatinine, which are indicators of how efficiently the kidneys are filtering waste products, particularly creatinine, from 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.

• Patients with known or suspected kidney disorders may undergo this test as part of routine monitoring or diagnostic evaluation.
• Individuals with conditions that may affect kidney function, such as diabetes or hypertension, may be advised to undergo regular GFR testing.
• People taking medications with potential renal side effects may have their GFR monitored to prevent drug-induced kidney damage.
• Patients preparing for surgery, especially those with existing kidney conditions, may undergo the test as a preoperative evaluation.

Some of the common tests that may be ordered along with the GFR with Creatinine Serum test include:

• Urinalysis: This test evaluates the urine for the presence of abnormal levels of protein, blood, or other substances that may indicate kidney dysfunction.
• Blood electrolyte tests: These tests evaluate the levels of electrolytes such as sodium, potassium, and calcium in the blood. Abnormal levels of these electrolytes may indicate kidney dysfunction.
• Kidney biopsy: In some cases, a small sample of kidney tissue may be removed and examined under a microscope to evaluate kidney function and identify the underlying cause of kidney disease.

• Creatinine-GFR Test
• Glomerular Filtration Rate (GFR) with Creatinine
