# Uric Acid Reagent Kit – 25 ml, 50 ml & 100 ml | Uricase / PAP Method # Swemed Uric Acid Reagent Kit The **Swemed Uric Acid Reagent Kit** is a professional clinical biochemistry reagent intended for the **quantitative determination of uric acid in serum, plasma and fresh urine** using the **Uricase / PAP enzymatic method**. Swemed's technical literature describes an enzymatic reaction in which **uricase converts uric acid to allantoin and hydrogen peroxide**. The hydrogen peroxide subsequently reacts with a phenolic compound and 4-aminoantipyrine in the presence of peroxidase to form a red quinoneimine dye. The intensity of the resulting colour is directly proportional to the amount of uric acid present in the specimen. For the Microsidd Shopify listing, this product is offered in convenient **25 ml, 50 ml and 100 ml pack-size options**. Swemed's current catalogue lists **Uric Acid 25 ml and 2 × 50 ml** under product code **UA 724**, while the technical insert also documents **2 × 25 ml and 2 × 50 ml** configurations. This supports laboratory procurement across 25 ml, 50 ml and 100 ml total reagent quantities depending on the supplied configuration.

Bacterial contamination should be avoided because it may affect uric acid concentration during storage. # Specimen Stability According to the Swemed technical insert: Storage Condition Stability 20–25°C **2 days** 2–8°C **3–5 days** −20°C **6 months** Contaminated specimens should be discarded. # Measuring Range and Linearity The assay is designed for uric acid concentrations between: **1–25 mg/dL** The stated linearity is: **25 mg/dL**. If a result exceeds the measuring range, Swemed instructs laboratories to dilute the sample **1:1 with 0.9% NaCl solution**, repeat the assay and multiply the obtained result by **2**. # Interfering Substances Swemed identifies several important analytical considerations. ### Ascorbic Acid Elevated ascorbic-acid concentrations may produce **falsely depressed uric acid values**. ### Lipemia Lipemic samples may cause **falsely elevated results**. ### Haemoglobin Haemoglobin up to approximately **100 mg/dL** was reported to have negligible influence within the manufacturer's stated tolerance, while higher concentrations may produce falsely elevated uric acid values. ### Bilirubin Bilirubin up to **30 mg/dL** was reported to have negligible interference under the evaluated assay conditions. # Manufacturer Reference Range Group Swemed Reference Range Men **3.4–7.0 mg/dL** Women **2.5–6.0 mg/dL** Swemed recommends that each laboratory establish or verify its own reference interval appropriate to its patient population. # Storage and Stability Store the reagent: - At **2–8°C** - Protected from light - Protected from contamination - **Do not freeze** - Use within the labelled expiry period - Bring reagents and specimens to room temperature as required before testing The current Swemed catalogue lists **24-month stability** for its Uric Acid reagent when stored correctly. # Signs of Reagent Deterioration The manufacturer advises against using the reagent if: - It becomes visibly turbid - Obvious microbial growth is present - The reagent blank absorbance reaches **0.250 or higher at 505 nm** # Safety and Precautions Swemed states that the reagent contains **sodium azide at 0.95 g/L as preservative**. Professional laboratory users should: - Wear suitable gloves - Use appropriate eye / face protection - Avoid skin and mucous-membrane contact - Never pipette by mouth - Follow Good Laboratory Practice - Handle reagent waste according to institutional procedures # Why Uric Acid Testing Is Important Uric acid is the final product of **purine metabolism** and is eliminated mainly through the kidneys. Swemed notes that increased uric acid concentrations may occur in conditions including gout and impaired renal function, while reduced levels may occur in selected metabolic or hepatic disorders. Uric acid testing is commonly used as part of: - Renal-function assessment - Hyperuricaemia investigation - Gout assessment - Metabolic profiles - Routine health screening - Monitoring of selected therapies - Kidney-function profiles - Clinical chemistry investigations Laboratory results should always be interpreted in the appropriate clinical context. # Uric Acid in an RFT / Renal Profile Parameter Laboratory Relevance Uric Acid Purine metabolism and renal excretion Urea Protein metabolism and renal excretion Creatinine Renal filtration-related biochemical marker Sodium Fluid and electrolyte balance Potassium Intracellular / renal electrolyte balance Chloride Fluid and acid-base balance Calcium Mineral metabolism Magnesium Mineral and metabolic balance This product is therefore particularly suitable for linking internally to your upcoming **Swemed RFT Reagent Combo Kit**. # Who Can Buy This Product?
