Q. What are the main tests for kidney function?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Understanding kidney function is crucial for assessing overall health. Several key tests help evaluate kidney function:
1. Serum Creatinine Test: This measures the level of creatinine in the blood, a waste product from muscle metabolism. Elevated levels can indicate reduced kidney function.
2. Blood Urea Nitrogen (BUN) Test: BUN levels in the blood can show how well the kidneys are filtering urea (a waste product). Elevated BUN can suggest kidney issues.
3. Glomerular Filtration Rate (GFR): GFR is calculated using serum creatinine levels, age, sex, and race. It estimates the rate at which the kidneys filter blood and is a key indicator of kidney function.
4. Urine Tests: These include Urinalysis and Urine Protein Test. Urinalysis checks for protein, blood, or other abnormalities. High protein levels may indicate kidney disease.
5. Imaging Tests: Ultrasound, CT scan, or MRI can provide detailed images of the kidneys to identify structural abnormalities or obstructions.
6. Kidney Biopsy: In some cases, a biopsy may be needed to examine kidney tissue under a microscope, especially when the cause of kidney disease is unclear.
Regular testing helps detect kidney problems early. If you have concerns about kidney health, consult a healthcare professional for personalized Kidney Function Test (KFT) advice.
