A single Uric Acid test ($21.99) is enough to track treatment once you are on it. Draw between flares, not during one — uric acid often reads falsely normal mid-attack. ## Recommended tests | Recommended | Type | Price | Why | | --- | --- | --- | --- | | [Gout Panel](https://www.test-well.com/tests/gout-panel) | Panel (3 tests) | $62.99 | Uric acid + CMP + hs-CRP — $62.99; the first-visit workup | | [Uric Acid](https://www.test-well.com/tests/uric-acid) | Test | $21.99 | The treatment-tracking test — $21.99; target below 6.0 mg/dL on therapy | | [Comprehensive Metabolic Panel](https://www.test-well.com/tests/comprehensive-metabolic-panel) | Test | $21.49 | Creatinine and eGFR decide urate-lowering drug dosing; glucose and liver enzymes come with it — $21.49 | | [Heart & Body Inflammation Test (hs-CRP)](https://www.test-well.com/tests/hs-crp) | Test | $26.99 | Systemic inflammation between and during flares — $26.99 | | [Renal Panel](https://www.test-well.com/tests/renal-panel) | Test | $22.99 | Kidney-focused alternative when the question is the kidneys — $22.99 | | [CBC with Differential](https://www.test-well.com/tests/cbc-with-differential) | Test | $17.99 | White count during a flare (infection vs gout); baseline before allopurinol | | [Lipid Panel](https://www.test-well.com/tests/lipid-panel) | Test | $19.99 | Gout travels with high triglycerides and cardiovascular risk | | [Hemoglobin A1c](https://www.test-well.com/tests/hemoglobin-a1c) | Test | $18.99 | Insulin resistance raises uric acid; half of people with gout have metabolic syndrome | All prices are cash-pay plus one $6 lab processing fee per order; physician authorization is included. ## What a blood test can — and cannot — tell you about gout Gout is inflammatory arthritis caused by monosodium urate crystals forming in and around a joint. Crystals form when blood uric acid stays above its saturation point, about **6.8 mg/dL**, for long enough — which is why the uric acid test is central. But it is a risk marker, not a diagnosis: roughly two-thirds of people with high uric acid never develop gout, and during an acute flare the level often drops into the normal range as urate moves into the inflamed joint. A normal uric acid mid-attack does not rule gout out; a high one in a painless person does not rule it in. The diagnosis itself is clinical or crystal-based: a classic first attack (a hot, swollen, exquisitely tender big-toe joint that peaks within 24 hours) scores high enough on the ACR/EULAR criteria to be treated as gout, and fluid drawn from the joint showing needle-shaped crystals is definitive. Blood tests do four other jobs well: they establish hyperuricemia and how far above target you are, they check the kidneys, which both cause gout and are damaged by it, they find the conditions that cluster with gout, and once treatment starts they are the only way to know it is working. ## The core tests and what each one shows **Uric acid (serum urate).** Above about 7.0 mg/dL in men and 6.0 in women is hyperuricemia on most lab ranges; crystals can form above 6.8. On urate-lowering therapy the target is **below 6.0 mg/dL**, and below 5.0 in people with tophi (visible urate deposits) or frequent flares. Draw it at least two weeks after a flare has settled, fasting is not required, and repeat it the same way each time — alcohol, dehydration, a heavy purine meal and diuretics all move it. **Creatinine and eGFR (on a comprehensive metabolic or renal panel).** The kidneys excrete two-thirds of the body's urate, so chronic kidney disease is one of the commonest reasons uric acid rises, and long-standing hyperuricemia in turn damages the kidneys. Kidney function also sets the starting dose and ceiling of allopurinol and whether probenecid can be used at all. The metabolic panel adds glucose, electrolytes and liver enzymes, which matter for febuxostat and for the metabolic picture. **hs-CRP.** A sensitive inflammation marker. It is high during a flare, often stays mildly raised between flares in people with frequent attacks or tophi, and falls as urate control is achieved. It cannot distinguish gout from infection or other arthritis, but a flare with a very high CRP, fever and a very high white count is septic arthritis until a joint aspiration says otherwise. **CBC with differential.** The white count helps separate a flare from infection, and a baseline count is standard before starting allopurinol, which rarely affects blood counts. Anemia with a high uric acid points toward kidney disease or a blood disorder with high cell turnover. **Lipid panel and HbA1c.** About half of people with gout meet the definition of metabolic syndrome; high triglycerides, low HDL, insulin resistance and fatty liver all raise uric acid, and gout independently raises cardiovascular risk. These are the tests that turn a gout diagnosis into a prevention plan. ## Who should test, and when - **After a first attack that sounds like gout** — a sudden, severe, red and swollen joint, classically the big toe, ankle or knee — draw uric acid, a metabolic panel and CRP once the joint has settled. If the attack is ongoing with fever or you are unwell, that is a same-day visit; the joint may need aspiration to exclude infection. - **High uric acid found by chance** on a routine panel, with no symptoms: repeat it, check the kidneys and the metabolic markers, and treat the causes — asymptomatic hyperuricemia is not treated with drugs under current guidelines, but it is a reason to look at weight, alcohol, sugary drinks, diuretics and kidney function. - **Starting or adjusting urate-lowering therapy** — allopurinol, febuxostat or probenecid: uric acid every 2–5 weeks while the dose is being titrated, then every 6 months once the target is held. Kidney and liver function at baseline and periodically. - **Recurrent flares or tophi despite treatment** — the uric acid tells you whether the dose is simply too low (the most common reason) before anything else is blamed. - **Family history, chronic kidney disease, diuretic use, or an organ transplant** — higher risk; a uric acid with the annual metabolic panel is reasonable. Timing matters more than fasting. Do not draw during a flare if the question is "how high is my baseline"; do draw it if the question is "is this gout or an infection", together with a CBC and CRP, and let the clinician read it in context. ## Reading the numbers together A **uric acid above 6.8 with normal kidney function and a normal CRP** in someone with typical attacks is uncomplicated gout: the priority is reaching target with urate-lowering therapy and the metabolic fixes. **High uric acid with a low eGFR** changes the plan — kidney disease may be the cause, the drug doses are capped, and nephrology input is often needed. **A normal uric acid with a classic attack** is still gout until shown otherwise; repeat the level two weeks later. **A flare with a very high CRP and white count**, especially with fever, needs the joint aspirated to exclude septic arthritis, which can coexist with gout. **High uric acid in a young person or with a strong family history** occasionally reflects an inherited handling defect or a blood disorder, and a 24-hour urine uric acid separates over-producers from under-excreters when the cause is unclear. On treatment, the single number that matters is the uric acid itself: flares in the first months of therapy are expected (urate is being mobilized) and are not a sign of failure, but a level still above 6.0 after dose titration is. ## How to get tested and what happens next Order the panel online, walk into any Quest or Labcorp location with your requisition — no appointment or doctor's visit needed — and results post to your account, most within one to two business days. No fasting is required for uric acid or CRP; the metabolic panel's glucose reads best fasting, so a morning draw before breakfast covers everything. Take the results to your clinician for the diagnosis and treatment decision; gout medication is prescription-only and the choice depends on your kidney function, other conditions and flare frequency. If you are already treated, a uric acid every six months at the same lab is the simplest way to be sure the dose is still right. ## Frequently asked questions ### Can a blood test diagnose gout? Not by itself. Gout is diagnosed from the clinical picture or by finding urate crystals in joint fluid. Uric acid can be normal during a flare and is high in many people who never get gout. Blood tests confirm hyperuricemia, check the kidneys and metabolic health, and track treatment — they support the diagnosis rather than make it. ### What uric acid level means gout? Crystals can form above about 6.8 mg/dL, and most labs flag above 7.0 in men and 6.0 in women. There is no level that equals gout — some people have attacks at 7 and others sit at 9 for decades without one. On treatment the goal is below 6.0 mg/dL, or below 5.0 if you have tophi. ### Should I test during a gout attack? If the question is your baseline level, no — uric acid often falls into the normal range during a flare, so draw it two or more weeks after the joint settles. If the question is whether a hot swollen joint is gout or an infection, yes: a CBC, CRP and uric acid the same day help, and the joint may need to be aspirated. ### Do I need to fast for a uric acid test? No. Uric acid and hs-CRP do not require fasting. The glucose on a metabolic panel does read best after an 8–12 hour fast, so a morning draw before breakfast is the simplest way to cover the whole Gout Panel in one visit. ### Why are my kidneys tested for gout? The kidneys excrete most of the body's urate, so reduced kidney function is one of the commonest causes of a high uric acid, and years of hyperuricemia damage the kidneys in turn. Kidney function also sets the dose of allopurinol and whether other drugs are safe, which is why creatinine and eGFR are part of every gout workup. ### How often should uric acid be checked on allopurinol? Every two to five weeks while the dose is being increased toward target, then about every six months once you are stable below 6.0 mg/dL. Kidney and liver function are checked at baseline and periodically. Flares in the first months of treatment are expected and are not a reason to stop. ## Sources - [FitzGerald JD, et al. 2020 American College of Rheumatology Guideline for the Management of Gout.
