The Creatinine, Random Urine test contains 1 test with 1 biomarker.
Description: A Creatinine Random Urine test is a urine test that is used to evaluate the health of your kidneys and diagnose and monitor the treatment of kidney disease.
Also Known As: Urine Create Test, Urine Creatinine Test, Random Urine Creatinine Test
Collection Method: Urine Collection
Specimen Type: Urine
Test Preparation: No preparation required
When is a Creatinine Random Urine test ordered?
During a health assessment, creatinine may be requested as part of a complete or basic metabolic panel. It may be ordered if a person is seriously ill or if a doctor feels that their kidneys aren't functioning properly.
When someone has a known renal condition or a disease that may impact kidney function, a creatinine blood test, coupled with a BUN test and urine albumin, may be ordered at regular intervals. When a CT scan is planned, before to and during some medication therapy, and before and after dialysis, both BUN and creatinine may be requested to assess the effectiveness of treatments.
What does a Creatinine Urine test check for?
Creatinine is a waste product created by muscles when a molecule called creatine is broken down. The kidneys eliminate creatinine from the body by filtering almost all of it from the blood and excreting it in the urine. The level of creatinine in the urine is measured in this test.
Creatine is a component of the energy-producing cycle that allows muscles to contract. The body produces both creatine and creatinine at a roughly steady rate. Because the kidneys filter almost all creatinine from the blood and excrete it in the urine, blood levels are usually an excellent predictor of how well the kidneys are operating. The amount produced is determined by the person's size and muscular mass. As a result, men's creatinine levels will be slightly higher than women's and children's.
A blood creatinine test's results can be combined with those from other tests, such as a 24-hour urine creatinine test, to produce calculations that are used to assess kidney function.
Lab tests often ordered with a Creatinine Random Urine test:
- BUN (Blood Urea Nitrogen)
- Creatinine Clearance
- Comprehensive Metabolic Panel (CMP)
- Basic Metabolic Panel (BMP)
- Microalbumin and Creatinine Ratio
- Cystatin C with eGFR
- Beta-2 Microglobulin
- Urine Protein
Conditions where a Creatinine Random Urine test is recommended:
- Kidney Disease
How does my health care provider use a Creatinine Random Urine test?
Kidney function is assessed with a creatinine blood test. It's usually requested in conjunction with a BUN test or as part of a basic or comprehensive metabolic panel, which consists of a series of tests designed to assess the operation of the body's primary organs. BMP or CMP tests are used to screen healthy persons during normal physical exams, as well as to help evaluate people who are acutely or chronically ill in the emergency room and/or hospital. Creatinine testing is sometimes done as part of a renal panel to assess kidney function.
Creatinine is a waste product created by muscles when a molecule called creatine is broken down. Because the kidneys filter almost all creatinine from the blood and discharge it into the urine, blood levels are usually an excellent predictor of how well the kidneys are operating.
The kidneys are a pair of bean-shaped organs placed on the right and left sides of the back at the bottom of the ribcage. Nephrons are a million microscopic blood filtering units found within them. Blood is continuously filtered by a small cluster of looping blood arteries called a glomerulus in each nephron. Water and tiny molecules flow through the glomerulus, but blood cells and bigger molecules are retained. Each glomerulus has a little tube attached to it that gathers the fluid and molecules that flow through it and then reabsorbs what the body can use. Urine is formed from the residual waste.
If the creatinine and BUN tests are abnormal, or if the patient has an underlying condition that affects the kidneys, such as diabetes or high blood pressure, creatinine and BUN tests may be used to monitor renal functionality and therapy effectiveness. Before some procedures, such as a CT scan, that may necessitate the use of medicines that can harm the kidneys, blood creatinine and BUN tests may be requested to assess renal function.
Creatinine test results can be utilized in calculations to determine renal function.
The estimated glomerular filtration rate, used as a screen to search for signs of early kidney damage, is calculated using blood creatinine readings, as well as age, weight, and sex.
What do my Creatinine Random Urine test results mean?
Elevated creatinine levels in the urine indicate renal disease or other disorders affecting kidney function.
We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.
