Does low urea nitrogen affect the physical examination of civil servants

Low urea nitrogen usually does not affect the physical examination of civil servants. Urea nitrogen is an indicator of kidney function, and a low level may be related to factors such as insufficient protein intake, abnormal liver function, and physiological changes during pregnancy. If there are no other abnormal indicators or clinical symptoms, it generally does not affect the physical examination results. Low levels of urea nitrogen are common in people with long-term low protein diets, malnutrition, or digestive and absorption disorders, and may also be related to decreased liver synthesis function. Part of the population may experience a temporary decrease in values due to increased metabolic rate or fluid dilution, such as testing after drinking a large amount of water. If only the urea nitrogen level is low and there are no accompanying abnormalities such as creatinine or uric acid during the physical examination, it is usually considered a non pathological change. The medical examination standards for civil servants mainly focus on major organic and infectious diseases. When the urea nitrogen deviates slightly from the reference value and there is no clear cause, most of them will not be judged as unqualified. In rare cases, low levels of urea nitrogen combined with abnormal other indicators should raise awareness of pathological conditions such as liver disease and pituitary dysfunction. If there is an increase in transaminase, a decrease in albumin, or abnormal thyroid hormone levels, further follow-up may be necessary. If multiple indicators show abnormal linkage in the physical examination report, it is recommended to improve liver function, thyroid function and other examinations to rule out potential diseases. However, such situations are relatively rare in the physical examination of civil servants, and low levels of urea nitrogen alone rarely lead to retesting or elimination.

Maintain a regular daily routine and balanced diet before the physical examination, avoiding excessive dieting or prolonged fasting time. If there is a history of chronic liver disease or malnutrition, renal function can be rechecked in advance and medical records can be carried for reference. The conclusion of the physical examination for civil servants needs to be comprehensively judged by clinical doctors, and there is no need to worry excessively about minor abnormalities in individual indicators.
