Oxalate, Spot Urine (OXASU)

Product Description

Price: 15 د.ا

The Oxalate, Spot Urine (OXASU) test is a diagnostic tool used to measure the concentration of oxalates in a urine sample. Oxalates are naturally occurring compounds found in many foods and are also produced by the body. This test is essential in diagnosing and managing conditions related to abnormal oxalate levels.

Normal Range

 Female

0.04 to 0.45 mmol/24 hours

Male

0.04 to 0.5 mmol/24 hours

Children

  – Infants: 0.03 to 0.14 mmol/24 hours

  – Older children: 0.04 to 0.45 mmol/24 hours

Function in the Body

Oxalates serve no known essential function in the body. They are primarily a byproduct of metabolism and are excreted through urine. However, oxalates can bind with calcium to form calcium oxalate crystals, which are the main component of most kidney stones.

Diseases Revealed by the Test

The OXASU test can help diagnose several conditions, including:

– Hyperoxaluria: A condition characterized by elevated levels of oxalate in the urine, which can lead to kidney stones and renal failure.

– Kidney Stones:High oxalate levels are a significant risk factor for the formation of calcium oxalate kidney stones.

– Primary Hyperoxaluria: A rare genetic disorder that causes excessive oxalate production. 

Symptoms

Symptoms of Elevated Oxalate Levels (Hyperoxaluria):

– Frequent urinary tract infections

– Painful urination

– Blood in urine (hematuria)

– Flank pain or back pain

– Frequent urge to urinate

– Kidney stones

Symptoms of Deficiency

Oxalate deficiency is not typically a concern, as oxalates are a waste product and not required for any bodily function. There are no known deficiency symptoms.

Symptoms of Overdose

High oxalate levels can cause:

– Severe abdominal pain

– Nausea and vomiting

– Joint pain

– Muscle weakness

– Difficulty breathing (in extreme cases)

– Formation of kidney stones

Diagnosis

The diagnosis of conditions related to abnormal oxalate levels typically involves:

  1. Medical History: Evaluating patient history for symptoms of kidney stones or other related conditions.
  2. Physical Examination: Checking for signs of urinary tract issues or kidney pain.
  3. Laboratory Tests: Performing the OXASU test to measure oxalate levels in the urine. Additional tests may include blood tests, 24-hour urine collection, and imaging studies like ultrasound or CT scans to check for kidney stones.

Frequently Asked Questions

Q – What does the OXASU test measure?

The OXASU test measures the concentration of oxalate in a spot urine sample to help diagnose conditions related to abnormal oxalate levels.

Q – How is the OXASU test performed?

A urine sample is collected, usually as a single voided specimen, and sent to a laboratory for analysis.

Q – How should I prepare for the test?

Your healthcare provider may advise you to avoid certain foods high in oxalates (e.g., spinach, nuts, chocolate) before the test to avoid temporary spikes in urine oxalate levels.

Q – What do high oxalate levels indicate?

High oxalate levels can indicate hyperoxaluria, risk of kidney stones, or primary hyperoxaluria, among other conditions.

Q – Can diet affect my oxalate levels?

Yes, dietary intake of high-oxalate foods can increase urine oxalate levels. Managing dietary oxalate is often part of the treatment plan for individuals with hyperoxaluria or recurrent kidney stones.

Q – Is the OXASU test the only test needed for diagnosis?

While the OXASU test is crucial, additional tests and imaging studies may be required to confirm a diagnosis and understand the underlying cause of abnormal oxalate levels.

Q – How are high oxalate levels treated?

Treatment may involve dietary modifications, increased fluid intake, medications to reduce oxalate production or absorption, and in severe cases, procedures to remove kidney stones or manage kidney damage.

 

Understanding the OXASU test and its implications can significantly aid in the early detection and management of conditions related to abnormal oxalate levels, ensuring better patient outcomes and quality of life.
