Creatinine clearance test – A creatinine clearance test is performed on a 24-hour urine sample. It tells your doctor how much creatinine your body excretes in a single day.
- Urinate into the toilet as you normally would when you wake up on the day you begin the test.
- Urinate into a specific container provided by your doctor throughout the rest of the day and night.
- During the collecting procedure, keep the container covered and refrigerated. Carefully and clearly label the container and take it to a doctor for your results.
Blood test– Blood samples are required for BUN (blood urea nitrogen) and serum creatinine testing, which must be taken in a lab or a doctor’s office. Blood samples can also be collected at home, for which you can book a test on the MFine app.
- Before extracting blood, the technician puts an elastic band around your upper arm. This draws attention to the veins.
- The technician then cleans the vein’s surrounding area.
- They insert a hollow needle into your vein through your skin. The blood will be collected in a test tube and taken to the lab, where it will be analyzed.
- After the test, the technician will cover the puncture site with gauze or a bandage.
Glomerular filtration rate test – It is the best test to determine the glomerular function (GFR). GFR is defined as the rate at which the substances in plasma are filtered through the glomerulus of the kidney. Glomeruli are filter-like networks of blood vessels and capillaries in the kidney that filter the blood. The GFR is measured in milliliters per minute, and it is done with the use of markers that can define the functionality.
- Using Insulin-The measurement of GFR using inulin is considered one of the best methods for GFR estimation. The patient needs to be infused with inulin into the bloodstream, and then blood levels are measured after a set amount of time to determine the rate of inulin clearance.
- Use of serum creatinine- Creatinine is the most often utilized endogenous marker for evaluating glomerular function. Urine must be collected during a 24-hour period, or preferably over a precisely scheduled period of 5 to 8 hours.
