what is low gfr in blood test?

Your GFR tells your doctor your stage of kidney disease and helps the doctor plan your treatment. If your GFR number is low, your kidneys are not working as well as they should. The earlier kidney disease is detected, the better the chance of slowing or stopping its progression.

You need dialysis when you develop end stage kidney failure --usually by the time you lose about 85 to 90 percent of your kidney function and have a GFR of <15. Click here to learn more about the stages of Chronic Kidney Disease and GFR.

eGFR is short for estimated glomerular filtration rate. Your eGFR is a number based on your blood test for creatinine, a waste product in your blood. It tells how well your kidneys are working. The eGFR is a good test, but it's not right for everyone.

Low creatinine clearance levels can mean you have chronic kidney disease or serious kidney damage. Kidney damage can be from conditions such as a life-threatening infection, shock, cancer, low blood flow to the kidneys, or urinary tract blockage.

Stage 4 kidney disease is the last stage before kidney failure. Once the glomerular filtration rate, or gfr, decreases to less than 15% the patient is considered to be in Stage 5 of chronic kidney disease. At less than 30% function the patient will be in Stage 4 kidney disease. Treatment options include dialysis.

['a blood test that checks how well your kidneys are filtering your blood, called GFR. GFR stands for glomerular filtration rate.', 'a urine test to check for albumin. Albumin is a protein that can pass into the urine when the kidneys are damaged.']

Your results could show a high concentration of sodium in both the urine and blood tests. But you could also have high levels in the urine and have normal or low levels in your blood when your body is losing too much sodium. Low sodium levels in the urine could indicate: Dehydration.

SGOT also helps the heart and kidneys, to a lesser extent. Low levels of SGOT in the blood are relatively common and not a cause for concern.

An estimated glomerular filtration rate (eGFR) of 55 milliliters per minute per 1.73 meters squared may be an early sign of chronic kidney disease (CKD). I recommend that you have urine testing as well for blood, protein and infection. This will help to establish if you have CKD.

A low RBC count may indicate anaemia, bleeding, kidney disease, bone marrow failure (for instance, from radiation or a tumour), malnutrition, or other causes. A low count may also indicate nutritional deficiencies of iron, folate and vitamin B12.

Creatinine clearance rates tend to fall later in life as the glomerular filtration rate (GFR - the rate at which the glomeruli filter the blood) declines. Certain drugs, such as aminoglycosides, cimetidine, cisplatin, and cephalosporins, can decrease the creatinine clearance measurement.

Because the “good” creatinine number is different in different people, GFR is more accurate in finding out if your kidneys are ok. Your GFR will help determine your stage of kidney disease. GFR and creatinine are usually measured and reported together.

Kidney function tests are common lab tests used to evaluate how well the kidneys are working. Such tests include: BUN (Blood urea nitrogen) Creatinine - blood. Creatinine clearance.

Most G.F.R. readings that fall below 60 in older adults remain in the 45 to 59 range, considered a modest reduction in kidney function. Most of these seniors will not have protein in their urine or other evidence of kidney damage.

High A/G ratio: This can be a sign of disease in your liver, kidney, or intestines. It's also linked to low thyroid activity and leukemia. If your doctor feels any of your levels are too high or low, you may need to have more precise blood or urine tests.

when gFR is below 60 for more than three months, this is moderate-to- severe chronic kidney disease. you may be referred to a nephrologist (kidney doctor) for evaluation and treatment. a gFR below 15 means kidney failure. if kidney failure occurs, dialysis or a kidney transplant will be needed to survive.

If GFR goes down, it's a bad sign. If creatinine goes up, it's a bad sign. In general, a “good” GFR number is above 60 and a “good” creatinine number is below 1.2.
