24-Hour Urine Cystine Test – Accurate HPLC Analysis for Kidney Health

Description

### 24-Hour Urine Cystine Quantitative Test – Accurate HPLC Analysis for Cystinuria

#### Why You Need This Test
The 24-Hour Urine Cystine Quantitative Test is a critical diagnostic tool for individuals at risk of or living with cystinuria, a rare genetic disorder that causes excessive cystine excretion in the urine. Elevated cystine levels can lead to the formation of cystine kidney stones, which are often recurrent and difficult to manage. This test provides a precise measurement of cystine concentration in a 24-hour urine sample, offering valuable insights into your metabolic health. By identifying abnormal cystine levels early, this test aids in diagnosing cystinuria, monitoring disease progression, and evaluating the effectiveness of treatment plans.

#### Symptoms That Indicate This Test
This test is recommended if you experience any of the following symptoms or conditions:
– Recurrent kidney stones, particularly those resistant to standard treatments.
– Persistent flank or abdominal pain associated with kidney stone formation.
– Blood in the urine (hematuria).
– Frequent urinary tract infections (UTIs).
– A family history of cystinuria or kidney stones.
If you are experiencing these symptoms, the 24-Hour Urine Cystine Quantitative Test can provide critical data to guide your healthcare provider in diagnosing and managing your condition.

#### Natural Production
Cystine is a naturally occurring amino acid formed by the oxidation of two cysteine molecules. It plays a role in protein structure and function. Under normal circumstances, the kidneys filter cystine and reabsorb it into the bloodstream. However, in individuals with cystinuria, a genetic mutation impairs this reabsorption process, leading to excessive cystine excretion in the urine. Factors such as hydration levels, diet, and genetic predisposition can influence cystine levels, making this test essential for accurate assessment and management.

#### What Happens If Untreated
If elevated cystine levels are left untreated, they can lead to the formation of cystine kidney stones. These stones are often large, recurrent, and resistant to standard treatments, causing significant pain and potential complications such as urinary obstruction, kidney infections, and long-term kidney damage. Early detection through the 24-Hour Urine Cystine Quantitative Test allows for timely intervention, reducing the risk of these complications and improving overall health outcomes.

#### How to Prepare for the Test
To ensure accurate results, follow these preparation guidelines:
– Collect all urine over a 24-hour period as instructed by your healthcare provider.
– Avoid excessive physical activity during the collection period, as it may affect cystine levels.
– Inform your healthcare provider about any medications or supplements you are taking, as some may influence test results.
– Stay hydrated but avoid overhydration, as it can dilute the sample.
