What uric acid level is too high?

Above about 6.8 mg/dL, urate begins to crystallise out of solution. For people who already have gout, the treatment target is below 6.0 mg/dL (360 µmol/L).

What is a safe uric acid level in µmol/L?

Below 360 µmol/L is the standard target, equivalent to 6.0 mg/dL. Below roughly 300 µmol/L is used where disease is more severe.

Why is my uric acid normal but I still have gout?

Lab reference ranges describe the general population, not gout treatment targets. Levels can also fall temporarily during an acute flare, so a test taken mid-attack can read lower than your usual value.

How often should I get tested?

That is your doctor's call, but it is common to test more frequently while a dose is being adjusted, then periodically once you are stable at target.

Coach Cherry pointing at a chart with a target line

Your lab says 'normal'. Your joints disagree. Both can be right — because the target for someone with gout is lower than the reference range.

The number

For people with gout, the widely used treatment target is below 6.0 mg/dL — or below 360 µmol/L if your lab reports in the units used across the UK, Europe, Australia and New Zealand. The 2020 American College of Rheumatology guideline recommends a treat-to-target strategy aiming under 6.0 mg/dL.

For people with more severe disease — visible tophi, frequent flares — a lower target of under 5.0 mg/dL is often used.

Why "normal" on your lab report can be misleading

Lab reference ranges describe the general population, and often run up to roughly 7.0 mg/dL for men. That range answers "is this unusual?" — not "is this safe for someone who already has urate crystals in their joints?"

The relevant threshold is physical, not statistical: urate starts to crystallise out of solution around 6.8 mg/dL. Staying meaningfully below that is what lets existing deposits dissolve. So a result of 6.9 can be flagged normal-ish by a lab and still be actively depositing crystals in your toe.

Converting between units

Multiply mg/dL by 59.48 to get µmol/L; divide to go the other way.

6.0 mg/dL ≈ 357 µmol/L (rounded to the 360 target)
5.0 mg/dL ≈ 297 µmol/L
7.0 mg/dL ≈ 416 µmol/L

One reading tells you very little

Uric acid moves — it drifts down over the course of a day, shifts with hydration, and can even drop during an acute flare, which is why a test taken mid-attack can be misleadingly reassuring. What matters is the trend across months, and whether it sits below target consistently.

That is the argument for keeping your own record rather than relying on whichever number your doctor read out last. Gout Coach charts every result against the 6.0 line in whichever unit your lab uses, and exports the history as a one-tap PDF for your next appointment.

Getting below target

Diet helps but rarely gets there alone — remember that dietary purines are only about a third of the picture. For most people, sustained control means urate-lowering therapy, adjusted by a doctor until the number sits below target and stays there.
