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.

The analytical parameters above are specified in the Swemed Uric Acid technical insert.
The assay uses uricase and peroxidase-based chemistry, providing an established enzymatic method for quantitative uric acid measurement.
Swemed states that both the reagent and standard are ready to use, simplifying routine laboratory workflow.
The availability of 25 ml, 50 ml and 100 ml total reagent options allows laboratories to choose according to testing volume, reagent turnover and workload.
Uric acid is frequently included alongside:
The assay parameters can be programmed on compatible open-system semi-automatic and fully automatic biochemistry analysers, subject to validation by the laboratory.
The Swemed Uric Acid Reagent Kit is intended for quantitative measurement of uric acid in professional clinical chemistry laboratories.
The manufacturer technical insert lists:
Swemed's online biochemistry catalogue also identifies Uric Acid as a Uricase/PAP method assay for serum and urine.
This product is for professional in vitro diagnostic use only.
The assay proceeds through two main enzymatic reactions.
First:
Uric Acid + H₂O —Uricase→ Allantoin + H₂O₂
The hydrogen peroxide formed then reacts with 4-aminoantipyrine and a phenolic compound in the presence of peroxidase to produce a red quinoneimine dye.
The intensity of the colour formed is proportional to the amount of uric acid present in the sample.
According to Swemed's product literature:

| Uricase | 200 U/L |
| Peroxidase | 4 kU/L |
| BSA | 1 g/L |
| Triton X-100 | 4 ml/L |
| Uric Acid Standard | 5 mg/dL |
The reagent and standard are ready to use.
No routine reagent reconstitution is required before following the manufacturer assay procedure.

Suitable system categories include:
The laboratory should verify analyser compatibility and validate the reagent application before routine patient reporting.
Swemed lists the following suitable specimens:
The manufacturer recommends using fresh, clear, non-haemolysed serum from fasting patients where appropriate.
Bacterial contamination should be avoided because it may affect uric acid concentration during storage.
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.
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.
Swemed identifies several important analytical considerations.
Elevated ascorbic-acid concentrations may produce falsely depressed uric acid values.
Lipemic samples may cause falsely elevated results.
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 up to 30 mg/dL was reported to have negligible interference under the evaluated assay conditions.
| 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.
Store the reagent:
The current Swemed catalogue lists 24-month stability for its Uric Acid reagent when stored correctly.
The manufacturer advises against using the reagent if:
Swemed states that the reagent contains sodium azide at 0.95 g/L as preservative.
Professional laboratory users should:
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:
Laboratory results should always be interpreted in the appropriate clinical context.
| 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 |
