How to check for high uric acid? Comprehensive analysis of detection methods and precautions
In recent years, with changes in lifestyle, the incidence of hyperuricemia has increased year by year, becoming an important hidden danger threatening health. So, how to scientifically detect uric acid levels? This article will combine the popular health topics on the Internet in the past 10 days to provide you with a detailed analysis of the methods, procedures and precautions for uric acid testing.
Uric acid testing is mainly done through blood, urine and imaging tests. The following is a comparison of common methods:
| Detection type | Applicable scenarios | Advantages | limitations |
|---|---|---|---|
| Serum uric acid test | Routine physical examination, suspected hyperuricemia | Fast and accurate results | Need to draw blood on an empty stomach |
| 24-hour urine uric acid test | Assess uric acid excretion capacity | Reflect long-term metabolic status | The collection process is cumbersome |
| Synovial fluid testing | Acute attack of gout | Direct diagnosis of gout | Need puncture sampling |
| Ultrasound/X-ray examination | Tophi or joint damage | Visualize lesions | Does not reflect uric acid concentration |
To ensure accurate results, please note the following:
1.fasting requirement: Serum testing requires fasting for 8-12 hours to avoid food affecting uric acid levels.
2.Diet control: Avoid high-purine foods (such as seafood, animal offal) 3 days before the test.
3.Avoid strenuous exercise: Uric acid may temporarily increase after exercise. It is recommended to keep quiet 24 hours before the test.
4.drug effects: Some diuretics and antihypertensive drugs may interfere with the results, so you need to inform your doctor in advance.
Normal values of uric acid vary slightly depending on gender and detection method:
| crowd | Normal range (serum) | hyperuricemia criteria |
|---|---|---|
| adult male | 208-428 μmol/L | >420 μmol/L |
| adult women | 155-357 μmol/L | >360 μmol/L |
| children | 120-320 μmol/L | >300 μmol/L |
Note: If a single test exceeds the standard, it must be confirmed based on clinical symptoms (such as joint swelling and pain) or repeated testing.
If the test confirms that uric acid is high, it is recommended to take the following measures:
1.lifestyle adjustments: Drink more than 2000ml of water per day, and limit alcohol and sugary drinks.
2.Diet management: Reduce the intake of red meat and seafood, and increase the intake of low-fat dairy products and vegetables.
3.Regular review: Test uric acid every 3-6 months and monitor changing trends.
4.Indications for medical treatment: Uric acid continues to be >540 μmol/L or gout symptoms require drug treatment.
Combined with the hot topics on the Internet, we sorted out high-frequency questions:
Q1: Is a home uric acid detector reliable?
A1: Portable instruments can be used as a reference for daily monitoring, but the values may deviate by 10%-15%, and a confirmed diagnosis still requires hospital testing.
Q2: Does asymptomatic high uric acid need treatment?
A2: If uric acid is >540 μmol/L or combined with hypertension/diabetes, intervention is recommended even if there are no symptoms.
Q3: What are the possible reasons for the sudden increase in uric acid?
A3: Strenuous exercise, heavy drinking, or taking aspirin in a short period of time may lead to false elevations.
Through scientific testing and standardized management, the problem of high uric acid can be effectively controlled. It is recommended that high-risk groups (obese, long-term drinkers, and those with family history) test uric acid at least once a year to nip problems in the bud.
