Oxalate-Citrate

Product catalog summary
Overview: The document provides detailed information on the use of oxalate and citrate tests for diagnosing hyperoxaluria and hypocitraturia, which are significant risk factors for kidney stones. It highlights the stability and adaptability of the reagents for use in clinical chemistry analyzers.
Key Sections:
1. Diagnostic Significance: Kidney stones form due to an excess of crystal-forming substances like calcium and oxalate in urine, or a lack of substances like citrate that prevent crystal formation. Hyperoxaluria and hypocitraturia are key conditions leading to stone formation.
2. Clinical Significance: Hyperoxaluria is characterized by urinary oxalate excretion levels exceeding 80 mg/24h, while hypocitraturia is indicated by citrate excretion below 150 mg/24h. These conditions are linked to metabolic acidosis and increased risk of kidney stones.
3. Test Characteristics: The oxalate test uses an oxidase/peroxidase method with a measuring range of 1.8 to 180 mg/L and a reagent stability of 60 days. The citrate test employs a lyase/malate dehydrogenase method with a range of 3 to 250 mg/dL and a 30-day reagent stability.
4. Product Specifications: The document lists various kits and controls for oxalate and citrate testing, including reagents, standards, and calibrators. These are designed for use in BioSystems automatic analyzers.
5. Analyzer Features: The analyzers are semi-automatic or fully automatic, with capabilities ranging from 150 to 200 tests per hour, suitable for different laboratory sizes and throughput requirements.
6. System Benefits: The BioSystems integral biochemical system is optimized for urinary stone diagnosis, offering user-friendly, reliable, and low-maintenance solutions.

Kidney stones (renal lithiasis, nephrolithiasis) are hard deposits made of minerals and salts that form inside your kidneys. Kidney stones form when your urine contains more crystal-forming substances, such as calcium, oxalate (hyperoxaluria) and uric acid, than the fluid in your urine can dilute. At the same time, your urine may lack substances that prevent crystals from sticking together (hypocitraturia), creating an ideal environment for kidney stones to form. The main symptoms for urinary stones are: • Frequent urge to urinate • Pain when urinating • Chills or fever • Severe or sudden back...
