Estimated Glomerular Filtration Rate 24 hour urine test is used to check and assess the functioning of your kidneys. It measures the creatinine levels in the blood. Estimated glomerular filtration rate is a calculation based on the serum creatinine test.
Kidneys are the main filtration system of the body. They efficiently filter blood and remove waste products from it and excrete them through urine and prevents the loss of proteins and blood cells. Each kidney consists of several glomeruli. Glomeruli are the tiny filters present inside the kidney. If there is an impairment in kidney functioning it means the glomeruli has failed to filter efficiently. In glomerular filtration rate, the amount of blood passing through the glomeruli per minute is estimated thus calculating the functioning of kidneys.
Creatinine is the breakdown product of the muscles of the body. It is released into the bloodstream and removed from the blood by the kidneys. Kidneys filter the creatinine and remove from the body via urine. Individuals whose kidneys are not working properly cannot filter the creatinine through it. This results in an increased level of creatinine in the blood and absence or low levels of creatinine in the urine.
This test may be recommended to you if you are suspected to have kidney dysfunction or kidney disorder. This test may be recommended when you experience symptoms like foamy or bloody or coffee colored urine, a decrease in the amount of urine, burning sensation while urinating, abnormal discharge during urination, swelling or puffiness around the eyes or the face, wrists, abdomen, thighs, or ankles, mid-back pain, pain below the ribs, etc. If the kidney disease worsens you may experience symptoms like itching, urinating more or less often, loss of concentration, tiredness, nausea or vomiting, swelling in the hands and feet, numbness, muscle cramps, etc. This test may be recommended if you have diabetes, hypertension, chronic kidney disease.
Some medications may interfere with the test results like cimetidine, cisplatin, ibuprofen, trimethoprim, flucytosine, cephalosporin antibiotics like cephalexin, cefixime, ceftriaxone, etc, aminoglycosides like streptomycin, amikacin, gentamicin, neomycin, etc. Certain conditions also affect the test results such as below 18 years, severely malnourished, underweight or overweight, bodybuilder, eating a lot of meat, eating low-meat diet or a vegetarian diet, change in kidney functions, pregnancy, neuromuscular disorder, a muscle-wasting disease. Hence inform your doctor or technician about all your current medications and medical conditions prior to the test.
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your EGFR Mass Spectrometry 24 Hour Urine. Your doctor will give specific instructions depending on your condition on how to prepare for EGFR Mass Spectrometry 24 Hour Urine.
No specific preparation is required for estimated glomerular filtration rate 24-hour urine test.
The normal test results may vary depending on race, gender, age, health history, height, weight, muscle mass, etc. Older people will have lower levels of glomerular filtration rate.
If estimated glomerular filtration rate test results are slightly less than the normal range it may indicate no damage to the kidney, lower than normal range may indicate mild damage to kidney, if the results are very less than the normal range it may indicate severe loss of kidney function and if the results are extremely lower than the normal range then it may indicate kidney failure. If you get abnormal test results, consult your doctor immediately. Your doctor may recommend other tests depending on your results.
