Creatinine, Random details
What Creatinine, Random shows
Creatinine is a waste product of muscle metabolism that the kidneys release into urine at a fairly steady rate. In a random urine sample, how much creatinine is present mostly reflects how concentrated the urine is. That makes it a useful reference: other substances measured in the same sample, such as albumin, metals or bone markers, are often reported as a ratio to creatinine to correct for dilution. A very low value suggests dilute urine, and a high one concentrated urine. It reflects muscle mass and hydration, and on its own is not a measure of kidney function.
Tests that include Creatinine, Random
This test measures the level of creatinine in your urine. Creatinine is a waste product produced by your muscles from the breakdown of a compound called creatine. This test is often used to check kidney function. A random urine sample is used, meaning the sample can be collected at any time. No special preservatives are needed.
- Creatinine, Random Measures creatinine in a random urine sample, mainly used as a reference to adjust other urine results for how concentrated or dilute the sample is.

NTx is useful to assess bone resorption in patients with metabolic bone disease. The test is also useful in monitoring therapy to slow or halt osteoporotic bone loss. A decline of 30% or more of NTx over a six-month period suggests effective therapy.
- Creatinine, Random Measures creatinine in a random urine sample, mainly used as a reference to adjust other urine results for how concentrated or dilute the sample is.
- N Telopeptide (NTx) Measures N-telopeptide (NTx), a fragment released when bone is broken down, in urine to help assess bone resorption and monitor treatment.
Copper, Urine measures the amount of copper excreted in urine over a specific period. It is used to assess copper metabolism and help diagnose conditions like Wilson’s disease or copper toxicity.
- Copper/Creatinine Ratio Compares urine copper to urine creatinine in a random sample, correcting for how dilute the urine is, to help look at copper excretion.
- Copper, Random Measures the concentration of copper in a random urine sample, used to help look at copper handling, particularly when Wilson disease is being considered.
- Creatinine, Random Measures creatinine in a random urine sample, mainly used as a reference to adjust other urine results for how concentrated or dilute the sample is.
Monitor response to antiresorptive therapy in postmenopausal women and individuals with osteoporosis. Does not replace bone mineral density (BMD) screening to diagnose osteoporosis.
- Creatinine, Random Measures creatinine in a random urine sample, mainly used as a reference to adjust other urine results for how concentrated or dilute the sample is.
- Deoxypyridinoline, Urine, Ratio to CRT Measures deoxypyridinoline, a bone collagen breakdown product, in urine relative to creatinine, to help look at the rate of bone resorption.
This test is considered the best method for checking oxidative stress in the body, which can be caused by a poor diet, smoking, a family history of heart disease, or high cholesterol. High levels may indicate a higher risk of hardening of the arteries (atherosclerosis) and some types of cancer.
- Creatinine, Random Measures creatinine in a random urine sample, mainly used as a reference to adjust other urine results for how concentrated or dilute the sample is.
- F2-Isoprostane/Creatinine Ratio F2-isoprostane in urine divided by urine creatinine, a corrected marker of oxidative damage to fats used to assess overall oxidative stress.
- F2-Isoprostane A marker of oxidative damage to fats in the body, measured in urine to help assess your overall level of oxidative stress.
This test combines two important assessments, the estimated glomerular filtration rate (eGFR) and the urine albumin-creatinine ratio (ACR), to help in the early detection of Chronic Kidney Disease (CKD). It aligns with the National Kidney Foundation's efforts to encourage the use of this profile for early CKD detection. Surprisingly, a study by NHANES (CDC) found that only a small percentage of individuals with reduced kidney function were aware of their condition. This test aims to increase awareness and early diagnosis of CKD.
