Is a urea creatinine ratio of 0.06 normal?

A urea or creatinine level of 0.06 refers to a concentration of 0.06 mmol/L, which is generally considered abnormal. The normal reference range for urea is 2.5–7.5 mmol/L, and for creatinine it is 8.4–13.25 mmol/L. A value of 0.06 mmol/L for either urea or creatinine falls well below the normal range and is therefore considered abnormal. Detailed analysis is as follows:

Urea is the end product of protein metabolism in mammals, synthesized in the liver via the ornithine cycle and excreted by the kidneys. It has a relatively small molecular weight. The normal range for urea is 2.5–7.5 mmol/L. A level of 0.06 mmol/L is significantly lower than normal and thus abnormal; however, this finding typically has limited clinical significance. It is often associated with factors such as malnutrition or a vegetarian diet, and can usually be corrected through dietary adjustments.

Creatinine is a metabolic byproduct of muscle activity and is primarily eliminated from the body via glomerular filtration in the kidneys. The normal creatinine range is 8.4–13.25 mmol/L. A value of 0.06 mmol/L is markedly below normal and indicates an abnormal condition. This may be related to conditions such as anemia, muscular dystrophy, hyperthyroidism, acute or chronic renal insufficiency, severe congestive heart failure, or leukemia. Patients are advised to seek prompt medical evaluation to avoid delays in diagnosis and treatment.

Patients experiencing any symptoms or discomfort should seek timely medical attention and follow standardized treatment under the guidance of a physician, which will help promote recovery.
