Introduction
In most hospitals, the upper limit for serum uric acid testing is 417–420 μmol/L. Exceeding this range indicates elevated uric acid levels, also known as hyperuricemia. Individuals with hyperuricemia are prone to gout—a condition characterized by acute synovitis and pain resulting from urate crystal deposition in certain joints. Elevated uric acid levels can also adversely affect the kidneys, potentially leading to gouty nephropathy.
With improvements in living standards, an increasing number of people are experiencing elevated uric acid levels in daily life—not only harming physical health but also significantly affecting quality of life and work performance. Understanding this condition is essential for effective prevention and treatment. So, how high must uric acid levels be to be considered “high”?
What Constitutes a High Uric Acid Level?
In most clinical laboratories, the upper reference limit for serum uric acid is typically set at 417–420 μmol/L. Levels exceeding this range indicate hyperuricemia. Individuals with elevated uric acid are at increased risk of gout—a form of acute inflammatory arthritis caused by deposition of monosodium urate crystals in joints. Hyperuricemia can also adversely affect kidney function, potentially leading to gouty nephropathy. Moreover, it is recognized as an independent risk factor for cardiovascular and cerebrovascular diseases.
For men, merely maintaining uric acid within the general “normal” reference range is insufficient. Clinical guidelines recommend that male patients achieve and sustain serum uric acid levels below 360 μmol/L to minimize the risk of recurrent gout attacks and gout-related kidney disease. For women, the target level is generally set below 400 μmol/L to further reduce potential harm to health. Thus, although the laboratory’s upper reference limit is commonly defined as 417–420 μmol/L, values below this threshold do not necessarily reflect optimal control. To meet therapeutic goals, uric acid should be maintained below 360 μmol/L in men and below 400 μmol/L in women.
In daily life, avoid spicy and irritating foods, drink plenty of water to promote metabolism, and engage in moderate outdoor physical activity to strengthen immunity. We hope this information proves helpful!
