Tracking Your Uric Acid: What Target, How Often?

When you have gout, you quickly latch onto the word "purines." You often overlook the most important thing: the number to watch over time, your serum uric acid — the level of uric acid in your blood. It, not the intensity of your last attack, tells you whether your gout is truly under control. Here's the target to aim for, how often to measure it, and how to read its trend.

Why uric acid is the real indicator

The pain of an attack always eventually fades. Uric acid, on the other hand, can stay too high with no symptoms at all for months. And it's that high, silent level that forms crystals, prepares the next attack, and, in the long run, damages joints and kidneys.

In other words: feeling fine doesn't mean gout is controlled. Only the blood test confirms it. That's the difference between treating the pain and treating the disease.

The target: below 6 mg/dL

International rheumatology guidelines set a clear goal for most patients on long-term treatment: a uric acid level below 6 mg/dL. Depending on the unit your lab uses, this corresponds to:

• less than 6 mg/dL (milligrams per deciliter), or
• less than 60 mg/L (milligrams per liter), or
• less than 360 µmol/L (micromoles per liter).

These are three ways of writing the same threshold — don't let the unit throw you off. Below this value, urate crystals gradually dissolve and attacks space out, then disappear.

For more severe forms (tophi, frequent attacks), the doctor may aim for an even lower target, often below 5 mg/dL, to dissolve the deposits faster. The exact target is a medical decision, specific to your situation.

How often should you get a blood test?

The rhythm depends on the stage you're at:

• At the start of long-term treatment, or at each dose adjustment: a close check (often every few weeks) to confirm you're progressing toward the target and to adjust the dose.
• Once the target is reached and stable: a more spaced-out check, generally about every 6 months, to make sure the level stays low.

These are indicative benchmarks: your doctor sets the frequency based on your treatment, your kidneys, and your history. The principle to remember is simple — you don't fly blind. Without regular measurement, there's no way to know whether the treatment is working.

Warning: uric acid can rise at the start of treatment

One point that surprises many patients: in the first weeks of long-term treatment, or during rapid weight loss, uric acid can temporarily climb and trigger an attack. This is not a sign of failure — it's a known phenomenon that your doctor anticipates (often with a preventive treatment at the start). All the more reason never to stop the treatment on your own at that moment.

How to read the trend over time

A single number tells you little; what matters is the trend. Uric acid that steadily drops toward the target and then stabilizes there is the sign of a treatment that's working. A value that rises should raise a flag — often because the treatment was interrupted or the dose is insufficient.

Keeping the history of your blood tests in one place, as a curve, makes this reading immediate — for you and for your doctor. That's exactly what the Gout-Cha! app offers: you record each uric acid result, the app shows your progression month by month against the target, and generates a PDF report to bring to your appointment. Enough to turn a stack of lab slips into a clear trajectory.

Follow-up: teamwork with your doctor

Tracking your uric acid doesn't replace the doctor — it gives them the data they need to adjust treatment. The patient who arrives at the appointment with a history of their levels and attacks enables finer, faster decisions. If you don't yet know which professional to turn to, start with your general practitioner. To go further, our article on preparing your appointment details what's worth writing down beforehand.

In summary

• Uric acid, not pain, is the real indicator of gout control.
• Usual target: below 6 mg/dL (= 60 mg/L = 360 µmol/L), sometimes lower depending on the case.
• Checks are frequent at the start then every 6 months once the target is stable.
• A temporary rise when starting treatment is normal — don't stop.
• It's the trend over time that matters; follow it with your doctor.
