A battery of blood tests is done to check the function of your kidneys with an EDTA test. The name of the drug that you will be given via injection is EDTA. A tiny quantity of radioactive material is present in EDTA. This enables it to operate as a tracer, revealing kidney function. A second dose of non-radioactive EDTA is given one week later. This test is used to find out if you are at risk for developing kidney problems over time. It can also help doctors identify any problem with your kidneys before it becomes serious enough to cause pain, illness or death. Your doctor may suggest other tests if EDTA testing isn't sufficient for your needs. Other common tests include: ACR - These tests measure the amount of protein in your urine. It is important to remember that even though you may have low levels of protein in your urine right now, this does not mean that you will always remain at this level. Your doctor may want to do more frequent tests to see how your protein levels change over time. ALBUMIN - Albumin is a protein that is made by the body. Healthy adults usually have levels between 35 and 52 grams per L of blood. Lower levels indicate that you are at risk for developing kidney problems over time. Higher levels indicate that you have problems with your liver instead.
