Given that creatinine is primarily produced in the muscle and serum creatinine levels are influenced by muscle mass, low creatinine levels may be an indication of frailty or low muscle mass.įurthermore, having low serum creatinine levels is linked to a higher risk of diabetes and prediabetes, particularly among older adults. Malnutrition leading to reduced muscle mass can also result in decreased creatinine production, she adds. “Pregnant people typically have lower levels of creatinine in their blood due to increased blood flow to the kidneys during pregnancy,” notes Dr. Low Levels of CreatinineĬommon reasons for low blood levels of creatinine include pregnancy, liver disease and malnutrition. Changes in creatinine levels can indicate the presence of certain health conditions, such as kidney diseases or disorders affecting muscle breakdown. This data point helps determine whether there’s a presence of albumin (a small protein) in the urine, which serves as an indication of kidney disease.Ĭreatinine levels are influenced by a variety of factors like age and sex and can fluctuate due to dehydration or changes in muscle mass. In order to evaluate kidney health comprehensively, it’s necessary to determine the urine albumin-to-creatinine ratio, according to Dr. Kidney function tests, also known as renal function tests, use eGFR alone or in combination with a urine test to evaluate the efficiency of waste clearance by the kidneys. Referred to as estimated GFR (eGFR), this calculation is widely recognized as a more accurate approach for assessing kidney function compared to relying solely on serum creatinine levels. To evaluate the efficiency of this filtration process, medical professionals assess the body’s glomerular filtration rate (GFR), an equation that takes into account an individual’s serum (or blood) creatinine levels in relation to their size, age and sex. The kidneys perform the vital function of filtering waste from the blood through a process called glomerular filtration. Creatinine levels can also be measured in urine samples, she adds. Crews, who adds that monitoring creatinine levels is one common way to assess kidney function. “Most people who have had routine bloodwork have had a creatinine test,” says Dr. Healthy kidneys are able to filter out most creatinine waste, but buildup can occur if a person’s kidneys are experiencing some form of dysfunction.

This waste, known as creatinine, is then filtered out of the blood by the kidneys before ultimately leaving the body through urine. The levels can, however, rise with the use of certain medications and the consumption of cooked meat.Īs the body uses creatine in muscles for energy, a small amount of waste is produced. Since one’s muscle composition doesn’t change significantly from one day to the next, creatinine levels tend to remain fairly consistent for healthy individuals. The amount of creatinine produced by an individual is directly related to their muscle mass. “Creatinine is a chemical left over from processes that take place in our muscles,” explains Deidra Crews, M.D., a professor of medicine in the division of nephrology at Johns Hopkins University School of Medicine and deputy director of Johns Hopkins Center for Health Equity.
