Price: 5 د.ا

The uric acid serum test is a blood test that measures the level of uric acid in the blood. Uric acid is a waste product formed from the breakdown of purines, substances found in certain foods and also naturally present in the body. This test is essential for diagnosing and managing various health conditions, such as gout, kidney stones, and more. In this article, we’ll explore the normal ranges of uric acid for different groups, its functions in the body, diseases revealed by the test, symptoms of deficiency and overdose, and common FAQs.

Normal Range

– Females: 2.4 – 6.0 mg/dL

– Males: 3.4 – 7.0 mg/dL

– Children: 2.0 – 5.5 mg/dL

Function in the Body

Uric acid plays a role in the body’s metabolism, particularly in the breakdown and elimination of purines. It is primarily excreted through the kidneys. Although uric acid itself is not harmful, high levels in the blood can lead to the formation of crystals in joints and tissues, causing inflammation and pain.

Diseases Revealed by the Test

1. Gout: A form of arthritis caused by the accumulation of uric acid crystals in the joints.
2. Kidney Stones: High uric acid levels can lead to the formation of kidney stones, which can cause severe pain and urinary issues.
3. Hyperuricemia: Elevated levels of uric acid in the blood, which may indicate an increased risk of cardiovascular disease and other health problems.

Symptoms

High Uric Acid Levels (Hyperuricemia)

– Joint pain, especially in the big toe

– Swelling and redness in joints

– Difficulty moving joints

– Kidney stones (painful urination, blood in urine)

 Low Uric Acid Levels (Hypouricemia)

– Fatigue

– Joint pain

– Nausea

– Increased risk of kidney damage

Symptoms of Deficiency and Overdose

Deficiency

– Muscle weakness

– Joint pain

– Fatigue

– Increased risk of infections

Overdose

– Severe joint pain

– Swelling and redness

– Chronic kidney disease

– Heart disease

Diagnosis

A uric acid serum test is performed by drawing a blood sample from a vein, usually in the arm. The sample is then analyzed to determine the concentration of uric acid. Your healthcare provider will interpret the results in the context of your symptoms, medical history, and other tests.

Yes, consuming foods high in purines, such as red meat, seafood, and alcohol, can increase uric acid levels.

3. How can I lower my uric acid levels?

To lower uric acid levels, you can adopt a low-purine diet, drink plenty of water, maintain a healthy weight, and limit alcohol intake. Medications may also be prescribed by your healthcare provider.

4. What are the risks of untreated high uric acid levels?

Untreated high uric acid levels can lead to the development of gout, kidney stones, and chronic kidney disease.

5. How often should I get tested for uric acid levels?

The frequency of testing depends on your medical history and risk factors. Your healthcare provider will advise you on how often you should get tested.

The uric acid serum test is a crucial diagnostic tool for identifying and managing various health conditions. Understanding your uric acid levels can help you and your healthcare provider make informed decisions about your health.
