Uric Acid Levels Explained: Normal vs High

You got your blood test results back.

There’s a number next to “serum uric acid” and you have no idea whether it’s good, bad, or somewhere in between.

Most of what’s out there is either buried in medical jargon or too vague to be useful.

Here’s what your uric acid levels actually mean, what’s considered normal, and what to do if your levels are putting you at risk for gout.

What Is a Serum Uric Acid Test?

A serum uric acid test measures the amount of uric acid in your blood.

Simple blood draw, usually from your arm.

Takes a couple of minutes.

Uric acid is a waste product your body produces when it breaks down purines, compounds found in certain foods and produced naturally by your cells.

The test tells you whether that system is working properly, or whether uric acid is building up to levels where it can cause gout.

How to Get Tested in Australia

Getting your uric acid levels checked is easy.

You don’t need to wait for a gout attack to justify it.

1. See your GP. Ask them to order a uric acid blood test. If you’ve had gout before, they’ll almost certainly agree. Mention your family history or risk factors. Most GPs will order it as part of a general health check.
2. Get the blood draw. Take your pathology form to a collection centre (like QML, Laverty, or Australian Clinical Labs). Walk in, get the draw, walk out.
3. Get your results. Results typically come back within 1-2 business days. Your GP will review them, or you can access them through the My Health Record portal or your GP’s patient app.

Do you need to fast?

Generally, no. Some doctors prefer a fasting sample for accuracy. Check when you get the referral.

Cost?

With a Medicare referral, the blood test is bulk-billed, meaning it costs you nothing.

Without a referral, expect to pay $30-60.

Understanding Your Numbers

Australian labs report uric acid in mmol/L (millimoles per litre), but a huge amount of the information online uses mg/dL (milligrams per decilitre).

You need to know both, because the research you’ll come across uses either one.

Conversion:

1 mg/dL = 0.059 mmol/L. Or roughly, multiply your mmol/L number by 17 to get the mg/dL equivalent.

Uric Acid Reference Ranges

Reference ranges vary slightly between labs.

Always check the range printed on your specific lab report.

Why Your Lab Range Can Be Misleading

The saturation point for uric acid is around 0.41 mmol/L (6.8 mg/dL).

Above that concentration, uric acid can start forming crystals in your joints.

Your lab report might show a “normal” range that goes up to 0.42 or even 0.44 mmol/L.

Many rheumatologists and gout specialists argue the real target should be below 0.36 mmol/L (6.0 mg/dL).

The Australian Rheumatology Association supports this lower target for people who’ve had gout.

You can get a result that falls within the lab’s “normal” range and still be at risk of crystal formation and gout attacks.

If your doctor says your levels are “fine” but you’re getting gout attacks, ask specifically what the number is.

Factors That Affect Your Uric Acid Levels

Your reading on any given day is influenced by several things.

Genetics

Up to 70% of the variation in uric acid levels is determined by your genes.

If your levels are high, your body may simply produce more uric acid or excrete less of it. Read more about gout and genetics.

Diet

High-purine foods (organ meats, shellfish, red meat) increase uric acid production.

Fructose also drives levels up.

Diet accounts for a smaller share of your total uric acid than most people think.

Hydration

Dehydration concentrates uric acid in your blood.

In a country where summer days hit 35+ degrees, this matters more than you think.

Alcohol

Beer is the worst offender.

Beer is high in purines and it blocks your kidneys from excreting uric acid effectively.

Medications

Some common medications raise uric acid levels, including certain diuretics, low-dose aspirin, and some blood pressure medications.

Kidney function

Your kidneys handle about two-thirds of uric acid excretion.

If kidney function is even slightly impaired, uric acid can build up.

Body weight

Higher body weight is associated with higher uric acid levels.

Even moderate weight loss can make a measurable difference.

Gender and age

Men generally have higher levels than women and are far more likely to develop gout before age 60.

Women’s levels tend to rise after menopause.

During a gout attack

Uric acid levels can actually drop during an acute gout attack.

If you’re tested mid-flare and the result comes back “normal,” that doesn’t mean your levels are fine.

Retest 2-4 weeks after the attack subsides for an accurate reading.

How Often Should You Test?

If your levels are normal and you’ve never had gout:

Every 1-2 years as part of routine blood work is reasonable, especially if you have a family history.

If your levels are elevated or you’ve had gout:

Test every 3-6 months.

You need data to know whether your changes are actually working.

If you’ve recently started a new supplement or medication:

Retest after 8-12 weeks.

If gout runs in your family:

Test annually, even if you feel fine.

Uric acid can be elevated for years before your first attack.

Keep a log of your results over time.

Trends tell you much more than any individual number.

What to Do If Your Levels Are High

Elevated uric acid is common.

In Australia, gout affects roughly 1.7% of the adult population and that number is climbing.

1. Talk to your GP

Get their perspective on what your specific number means.

2. Address the controllable factors

Hydration, diet, alcohol, and body weight are all things you can influence.

Cut back on beer. Drink more water. Reduce sugary drinks.

These three moves alone can make a real difference.

3. Consider natural support

Specific natural compounds have research behind them for supporting healthy uric acid levels.

Tart cherry extract, celery seed extract, and chanca piedra are among the most studied.

4. Don’t rely on diet alone

Because genetics account for such a large portion of your uric acid levels, diet changes alone often aren’t enough.

Approach gout management from multiple angles.

5. Retest and track

Give your changes 2-3 months, then retest.

Compare the numbers. Adjust.

The Bottom Line

A uric acid blood test is one of the most useful and underused tools for managing gout.

It’s free with a Medicare referral, it takes five minutes, and it gives you a clear number to work with.

Know your number. Understand what it means. And if it’s high, do something about it now.
