What does a low uric acid level in the blood mean?

A low level of uric acid in the blood is usually due to:

  • A kidney disorder that causes an excessive excretion of uric acid in the urine.
  • A vegetarian diet or with a low-purine intake.

Uric acid values are usually given in mg/dl but sometimes you can see those values in nmol/l following the International System of Units (SI). In case your values are in nmol/l you can convert them using this tool:

µmol/l
  • Mild hypouricemia (2 - 3.5 mg/dl adult men and 2 - 2.6 mg/dl in adult women):

    The uric acid level in the blood is a bit low but not a matter for concern. Maybe your diet is unbalanced for example a vegetarian diet low consumption of purines.

    You should eat more food rich in purines to check if your values return to normal range in a future blood test. Otherwise, additional screening test should be performed.

  • Marked hypouricemia (< 2 mg/dL in adults):

    Your acid uric level is extremely low.

    It can be seen in case of an unbalanced diet with an important deficit of purines, molybdenum or folic acid.

    If you follow a balanced diet, it may suggest a genetic disorder that blocks the purine absorption or its transformation in uric acid. You should visit your doctor to study a possible hereditary metabolic disorder such as Fanconi syndrome or Wilson’s disease.

To increase the purine intake, so they can be transformed into uric acid, it is possible to eat some vegetables, legumes and fish rich in purines. For example:

  • Vegetables: Asparagus, spinach or mushrooms
  • Legumes: Beans or lentils
  • Fish: Sardines or trout
