Understanding gout
Uric acid levels, explained
A typical lab calls uric acid normal up to about 7.0 to 7.2 mg/dL for men and about 6.0 for
women, and the exact range varies by lab. Chemistry is stricter than the lab range: urate
typically starts crystallizing above roughly 6.8 mg/dL at body temperature, which is why
treatment guidelines target below 6.0. So a man can be told his level is normal at 7.0 and
still sit above the point where crystals typically start to form. This page walks each band,
with the study behind every number.

This page explains what the numbers mean. It cannot interpret your result for you - that is a
conversation with your doctor, who sees the whole picture.
The bands, one by one
All values are serum urate in mg/dL. To convert a result in µmol/L, divide by roughly 59.5
(360 µmol/L is about 6.0 mg/dL).
Below 6.0 The treatment target
Where guidelines want you if you have gout. The American College of Rheumatology strongly recommends treating to below 6, and European guidance uses below 5 for severe gout until crystals dissolve.

6.0 to 6.8 Above target, below saturation
Higher than guidelines want for someone with gout, and typically still below the level where urate starts to crystallize.

About 6.8 The saturation point
Above roughly 6.8 mg/dL, blood is typically supersaturated and monosodium urate crystals can start to form. This is not a hard line: solubility falls as temperature drops, so a joint that runs cooler than the rest of the body, like the big toe, can see crystals form at a lower reading than this.

6.8 to 9.0 Supersaturated, and often still "lab normal"
Many labs flag men only above 7.0 to 7.2, so a reading in this band can come back marked normal while sitting above the level where urate typically starts to crystallize. Gout risk in this band ran about 0.5% per year in the long-term cohort data.

Above 9.0 The highest-risk band
About 4.9% per year developed gout at this level, 22% over five years, in the 15-year study that followed 2,046 men. Which also means roughly four in five did not, even here. A number, not a diagnosis.

Why the internet disagrees about "normal"
Look this up on three sites and you will get three ranges, because "normal" is answering two
different questions. Lab reference ranges describe what is common in the population a lab
serves - they vary by lab and assay, and for men they usually top out around 7.0 to 7.2. The
chemistry question, at what level urate typically starts to crystallize, has a tighter
answer: about 6.8. The honest reading of your lab report is that "normal" means "common," not
"safe for someone with gout."

A high number is not gout
About 20% of US adults have high uric acid. About 3.9% have gout. Most people with a high
reading never develop it: in the study that followed 2,046 men for 15 years, even those at
9 mg/dL and above developed gout at about 4.9% per year - 22% over five years, so roughly
four in five did not. Below 7.0 the rate was 0.1% a year. One caveat worth stating: that
cohort was men, so the exact rates do not transfer cleanly to women.

The number can lie during a flare
Testing in the middle of an attack can mislead. In the largest study of acute gout, 14% of
people in an active flare had uric acid at or below 6 mg/dL and about a third were at or
below 8. A normal result during a flare does not rule gout out, which is why doctors often
retest a few weeks after it settles. If you are trying to work out whether an attack is gout
at all, start with do I have gout?

What actually moves the number
Less than most sites imply, and it is better to know that going in. In the one randomized
trial, the DASH eating pattern lowered urate by 0.35 mg/dL on average - and by 1.29 mg/dL in
people starting at 7 or higher, so diet helps most where it is needed most. Zoom out and the
biggest analysis found diet patterns explain under 1% of the difference in urate between
people, against about 24% for common genetic variants. Alcohol and sugary drinks push the
number the wrong way - the gout diet and
drinks pages carry those numbers. For
what diet can and cannot do alongside medication, see
medication and diet.

When doctors treat the number
For people with gout, both major guidelines agree on treating to a target: below 6 mg/dL
(ACR 2020, a strong recommendation), with European guidance adding below 5 for severe gout
until crystals dissolve. For a high number without any symptoms, guidelines generally do not
recommend medication. Worth knowing either way: only about a third of Americans with gout are
on urate-lowering therapy at all, so if you have gout and have never discussed a target with
your doctor, that conversation is the single highest-value thing this page can point you to.

Quick answers
What is a normal uric acid level?
A typical lab reports uric acid as normal up to about 7.0 to 7.2 mg/dL for men and about 6.0 for women, and the exact range varies by lab. Chemistry is stricter than the lab range: urate typically begins crystallizing above roughly 6.8 mg/dL at body temperature, which is why treatment guidelines target below 6.0 for people with gout.
Is a uric acid of 7.2 high?
It depends who is asking. Many labs would call 7.2 normal or borderline for a man, but it sits above the roughly 6.8 mg/dL level where urate typically starts to crystallize. In long-term data, people at 7.0 to 8.9 developed gout at about 0.5% per year. It is a number worth discussing with a doctor, not a diagnosis.
Can uric acid be normal during a gout attack?
Yes. In the largest study of acute gout, 14% of people in an active flare had uric acid at or below 6 mg/dL, and about a third were at or below 8. A normal result during a flare does not rule gout out, which is why doctors often retest a few weeks after it settles.
Does a high uric acid level mean I will get gout?
Usually not. About 20% of US adults have high uric acid while 3.9% have gout. Even at 9 mg/dL and above, the long-term rate was about 4.9% per year, meaning roughly four in five people at that level did not develop gout over five years. A high number is a risk factor to discuss with your doctor, not a diagnosis.
