# Urate (UA)

A waste product of purines and fructose; tracks diet, alcohol, kidney handling and metabolic health.

Type: lab · Unit: mmol/L (µmol/L ÷ 1000; mg/dL × 0.0595) · Domain: Metabolic Health · Accuracy: Laboratory · Importance: Core

Also called: uric acid, serum urate, uric acid level, gout test

## Ranges

- Laboratory range: 0.20–0.42 mmol/L (men) · 0.14–0.36 mmol/L (women)
- Working optimal: < 0.36 mmol/L (men) · < 0.30 mmol/L (women) · ref. 3

## In one sentence

The end product of breaking down purines, the building blocks of DNA that also arrive in meat, seafood, beer and the fructose in sugary drinks; the kidneys clear most of it, and when it stays high enough for long enough it crystallizes in joints.

## Why it matters

For a well adult urate is read as a metabolic marker before it is read as a joint one, because it tracks insulin resistance, fructose and alcohol. In 8,669 US adults in NHANES III, the prevalence of the metabolic syndrome rose from 18.9 percent in people with urate below 0.36 mmol/L (6 mg/dL) to 70.7 percent at 0.59 mmol/L (10 mg/dL) and above, and the trend held in every subgroup, including people with a body mass index under 25 (Choi 2007). In 46,393 men followed for twelve years, two or more sugar-sweetened soft drinks a day carried a relative risk of gout of 1.85 compared with less than one a month, fructose intake by fifths ran from 1.00 to 2.02, and diet soft drinks carried none (Choi 2008). Urate becomes insoluble at about 0.41 mmol/L (6.8 mg/dL), the figure behind most laboratories' upper limits.

## What moves it

Up: fructose and sugar-sweetened drinks, beer and spirits, meat and seafood, dehydration, fasting and rapid weight loss, the early weeks of a ketogenic diet, diuretics and low-dose aspirin, and the genes that set how the kidneys handle it. Down over months: weight loss, less alcohol and sugar, dairy and coffee in the diet. It can fall during an acute attack of gout and read falsely reassuring, which is a laboratory and clinical point the entry notes without advising on.

## How to measure it well

A fasting morning draw, no alcohol for 48 hours, not during an acute joint flare, hydrated as on an ordinary day. New Zealand laboratories report mmol/L; European reports often use µmol/L and American ones mg/dL, and VT converts both.

## How Vitality Tracker uses it

Stored as reported with the laboratory's range and flag, never overridden; typical laboratory reference 0.20 to 0.42 mmol/L in men and 0.14 to 0.36 in women. VT's working optimal (v0.1), beneath in smaller type and marked *working*: below 0.36 in men and below 0.30 in women. Urate sits in the metabolic cluster of the pre-visit report, and when a keto plan is active the plan is shown beside the result as context for an early rise. Re-test yearly, or at six months when a supplement, a medicine or heavy training is new.

## How far to trust the number

Laboratory: a precise enzymatic assay; the variation is diet and hydration, so a single value after a weekend is not a baseline.

## Method

No calculation. Conversions: µmol/L × 0.001 = mmol/L; mg/dL × 0.05948 = mmol/L.
