1.What are kidney function tests?
Kidney function tests are a group of laboratory tests used to assess how well the kidneys are working. The tests measure various substances in the blood and urine that are filtered by the kidneys or produced by them. There are several types of kidney function tests, including:
Blood tests: These tests measure the levels of waste products, such as creatinine and blood urea nitrogen (BUN), in the blood. Elevated levels of these substances can indicate that the kidneys are not functioning properly.
Urine tests: These tests measure the amount of protein, glucose, and other substances in the urine. Abnormal levels of these substances can indicate that the kidneys are not filtering properly.
Imaging tests: These tests use X-rays, ultrasound, or other imaging techniques to visualize the kidneys and detect any abnormalities, such as tumors, cysts, or kidney stones.
Biopsy: In some cases, a kidney biopsy may be performed to determine the cause of kidney dysfunction. A small sample of kidney tissue is removed and examined under a microscope.
These tests can help diagnose kidney disease or monitor the progression of an existing kidney condition. They are often performed as part of a routine checkup, especially in people with risk factors for kidney disease, such as high blood pressure or diabetes.
2.When might I need the kidney function test?
A kidney function test, also known as a renal function panel or kidney panel, is a blood test that helps evaluate how well your kidneys are functioning. Your doctor may recommend this test if you have symptoms or risk factors for kidney disease, or as part of a routine health checkup.
Here are some situations in which you might need a kidney function test:
If you have high blood pressure or diabetes: These conditions can damage the kidneys over time, so your doctor may want to monitor your kidney function regularly.
If you have symptoms of kidney disease: These may include swelling in your legs or feet, frequent urination, blood in your urine, or difficulty urinating.
If you have a family history of kidney disease: Some forms of kidney disease can be hereditary, so your doctor may recommend testing if you have a family member with kidney disease.
If you are taking medications that can affect the kidneys: Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or some antibiotics, can cause kidney damage, so your doctor may want to monitor your kidney function if you are taking these drugs.
If you are over age 60: As you age, your kidney function may decline, so your doctor may want to monitor your kidney function as part of a routine health checkup.
3.What are the types of kidney function tests?
Blood tests: Blood tests are used to measure the levels of creatinine and blood urea nitrogen (BUN) in the blood. Elevated levels of these substances can indicate kidney damage or dysfunction.
Urine tests: Urine tests can be used to measure the amount of protein, blood, and other substances in the urine. Abnormal levels of these substances can indicate kidney damage or dysfunction.
Glomerular filtration rate (GFR) test: This test measures how well the kidneys are filtering waste products from the blood. It is calculated based on a person’s age, gender, race, and serum creatinine levels.
Imaging tests: Imaging tests such as ultrasound, CT scans, and MRI can be used to visualize the kidneys and detect any abnormalities or blockages.
Biopsy: In some cases, a kidney biopsy may be performed to examine a small sample of kidney tissue under a microscope to determine the cause of kidney dysfunction.
4.Can I test the creatine, uric acid and urea level when I ' home?
Yes, you can. The Lysun Renal Function Analysis Meter can make it happen.
