There are many things to know about kidney function at different ages. They are one of the most important organs, and their malfunctioning can result in a host of medical problems. The measure of creatinine levels indicates how well they are. Abnormal ranges of creatinine can be detected via blood and urine tests.
Creatinine clearance blood test
At Avigna Diagnostics, our technicians perform tests for kidney disease, which is important for a healthy life. This blog explains everything that you should know if your doctor has asked for a diagnostic creatinine urine test.
We cover the following points:
- What is a creatinine clearance blood test?
- Common signs that doctors prescribe the test.
- How to prepare for the test and analysis
Every day, we use our muscles and the waste created is called creatinine. The chief function of the kidneys is to remove this material through the urine. If it does not get eliminated, it builds in the bloodstream. Thus, when a doctor suspects a problem, he will ask the patient to undergo tests for kidney disease.
Common signs and symptoms
In the early stages, there are no visible symptoms, but some signs do appear. They include:
- Puffy eyes in the morning
- Increased urination and muscle cramps in the night
- Trouble creating focus or sleeping
- Fatigue
- Swelling around the feet and ankles
- Dry and itchy skin
Tests are also required for predisposed medical conditions like diabetes and high BP. Measurements become more relevant if there is a family history of kidney malfunction.
Diagnostic for creatinine urine test
Preparation for the tests
At the lab, the technician will draw blood in a standard way. A urine sample will also be taken. If required, you may have to fast in the night. Just before the tests are conducted, supplements and meat should not be consumed to ensure that the reading is correct. The results are interpreted by the laboratory head, and the findings are given to the doctor. High creatinine levels are an indication of poor kidney function.
The typical measurement of a normal range is
Men: 0.74 to 1.35 mg/dL (65.4 to 119.3 micromoles/L)
Women: 0.59 to 1.04 mg/dL (52.2 to 91.9 micromoles/L)
The creatinine clearance is taken after measuring the samples given 24 hours earlier. Accurate timings for samples are critical to obtaining the right readings. The age group of the patient is an important consideration in checking the blood flow towards the kidneys.
Albumin and Creatinine ratios
When the urine sample is taken, the albumin (blood protein) and creatinine ratios are also measured. Healthy kidneys will not release any albumin in the urine. If the kidneys are healthy, the readings will show up like this:
Men: less than 17 mg/g
Women: less than 25 mg/g
If the level is high, then it indicates kidney disease. A doctor fully understands the readings. This information is merely to offer the best interpretation of the importance of creatinine levels.
Avigna Diagnostics conducts several laboratory tests for kidneys. A doctor may ask for additional tests that normally affect this important organ to make a proper diagnosis. Always rely on the professional for direct treatment and responses to get back to health.
