![]() ![]() Healthcare providers like to keep an eye on creatinine levels for various reasons. Once these values are normalized, changes from this range can signify abnormalities of the kidney.” “This depends on age, race, gender, and body size. “Creatinine level assessment starts with getting a demographic baseline to assess what ‘normal levels’ should be,” Dr. To accurately measure blood creatinine levels, a doctor will first assess these various factors to establish a baseline, according to Taylor Graber, MD, an anesthesiologist and founder of ASAP IVs. Muscle breakdown creates creatinine, so your muscle mass and activity level can influence the amount in your blood. However, there are a lot of variables when it comes to normal levels of creatinine. In most cases, the normal range for serum creatinine (found in the blood) for someone with healthy kidneys is 0.7 to 1.3 mg/dL for adult males and 0.6 to 1.1 mg/dL for adult females. For this reason, healthcare providers will often use a creatinine test-along with other lab tests, like a blood urea nitrogen (BUN) test-to monitor for chronic kidney disease (CKD) or renal failure.Ĭreatinine levels are measured in milligrams per deciliter (mg/dL). Even though creatinine doesn’t actively benefit (or harm) your body, the amount of creatinine in your blood can be measured to evaluate your kidney health. After being used for energy, creatine is broken down into creatinine, which re-enters the bloodstream en route to the kidneys.Ĭreatinine is released from the muscles and enters the bloodstream to be filtered at a relatively constant rate. During exertion, your muscles convert the stored creatine molecules into energy, which assists in muscle contraction. However, creatine is mainly stored in its phosphorylated form, known as phosphocreatine or creatine phosphate. Creatine is transported via blood flow to the skeletal muscles where it is stored in free and phosphorylated forms. So, how does your body generate creatinine? It starts with creatine, which is mainly synthesized in the kidneys, pancreas, and liver. It simply stays in the blood until reaching the kidneys, where it’s filtered and eliminated through urination. Creatinine itself doesn’t have a specific physiological function-it’s just a waste product. Creatinine is a natural byproduct of muscle use, caused by the breakdown of a chemical called creatine. What is creatinine?Įveryone has certain serum creatinine levels in their bloodstream. ![]() While it might be the last thing you think about while exercising, your blood creatinine levels can be a key indicator of your renal health and kidney function. When your muscles break down during exercise, they slowly build back up, increasing muscle mass, but this process also releases waste products into your blood, primarily creatinine. But there’s a whole lot more going on under the surface. ![]() Like most people, you’re acutely aware of how physical activity makes your body feel- the breathing, sweat, and heat. And when you’re done, nothing feels better than a warm shower, a cold glass of water, and a seat on the couch. You’re breathing fast, and your muscles are on fire. You’re 10 minutes into your afternoon jog, powering through your daily exercise routine, or biking around the neighborhood.
