Hypouricemia or hypouricaemia is a level of uric acid in blood serum that is below normal. In humans, the normal range of this blood component has a lower threshold set variously in the range of 2 mg/dL to 4 mg/dL, while the upper threshold is 530 μmol/L (6 mg/dL) for women and 619 μmol/L (7 mg/dL) for men.

Gout can occur where serum uric acid levels are as low as 6 mg per 100 mL (357 μmol/L), but an individual can have serum values as high as 9.6 mg per 100 mL (565 μmol/L) and not have gout. [ 18 ] In humans, purines are metabolized into uric acid, which is then excreted in the urine.
There appears to be the greatest cluster of substances in the yellow part (μg/L or nmol/L), becoming sparser in the green part (mg/L or μmol/L). However, there is another cluster containing many metabolic substances like cholesterol and glucose at the limit with the blue part (g/L or mmol/L).
When lactate levels are elevated, blood-borne lactic acid competes for the same kidney tubular transport mechanism as urate, limiting the rate which urate can be cleared by the kidneys into the urine. If present, increased purine catabolism is an additional contributing factor. Uric acid levels of 6 to 12 mg/dl (530 to 1060 umol/L) are common ...
Unless high blood levels of uric acid are determined in a clinical laboratory, hyperuricemia may not cause noticeable symptoms in most people. [4] Development of gout – which is a painful, short-term disorder – is the most common consequence of hyperuricemia, which causes deposition of uric acid crystals usually in joints of the extremities, but may also induce formation of kidney stones ...
Written by five-time New York Times bestselling author David Perlmutter, M.D., Drop Acid suggests that high levels of uric acid, an overlooked “waste product” of metabolism, can lead to many ...
Some have pointed to a variety of causes, including increased uric acid levels caused by dietary fructose. [ 27 ] [ 28 ] [ 29 ] Research shows that Western diet habits are a factor in the development of metabolic syndrome, with high consumption of food that is not biochemically suited to humans.
High turnover of tumor cells leads to spill of potassium into the blood. Symptoms usually do not manifest until levels are high (> 6.5 mmol/L) [normal 3.5–5.0 mmol/L] and they include [8] palpitations, cardiac conduction abnormalities, and arrhythmias (can be fatal) muscle weakness or paralysis; Hyperphosphatemia.
