What is the normal urea nitrogen value?

In general, the normal value of urea nitrogen should be 2.9~7.5mmol/L. The normal value of women may change during pregnancy. The normal value of newborns should be 1.4~4.3mmol/L. The urea nitrogen mainly refers to the content of urea nitrogen in plasma, which is mainly used to judge the glomerular filtration function of patients. If the patient goes to the hospital for examination and finds that urea nitrogen is not within the normal range, it must be paid attention to. Further examination should be done to clarify the specific diagnosis and symptomatic treatment.
