Glucose assay kit(Classification No.: 30167002)

Intended Use
Measurement of glucose in serum, plasma or urine.

Pureauto S GLU-R

Assay Principle
1. Assay Principle
Glucose is converted to glucose-6-phosphate by
the action of hexokinase (HK) in the presence ofATP. Glucose-6-phosphate is converted to 6phosphogluconic acid by the action of glucose-6phosphate dehydrogenase (G-6-PDH). At thesame time, NAD is converted to NADH, and theabsorbance at 340 nm increases. The glucose levelis determined by measuring the change in theabsorbance of NADH.
HKGlucose + ATP
Glucose-6-phosphate + ADP
Mg2+

Warning
Measured blood glucose levels may be higher than
the actual values in patients with pralidoxime
methyl iodide treatment. Therefore, obtain
information from the manufacturing authorization
holder of pralidoxime methyl iodide concerning its
influence on measurement of blood glucose insuch patients.
(Measured blood glucose levels may be higher
than the actual values in patients with pralidoxime
methyl iodide treatment. If hypoglycemic drugs
such as insulin are administered on the basis offalse high values, serious symptoms ofhypoglycemia such as coma may occur.)

2. Features
1) Liquid reagents, ready-to-use.
2) Because this product has the widemeasurement range, even urine samples canbe measured without dilution.
3) Analytical results are hardly affected byinterfering substance, because the rate
method is used.
4) This product shows a high sensitivity andreproducibility.

General Precautions
1. This product is for in vitro diagnostic use, andmust not be used for any other purposes.
2. Clinicians should make a comprehensive clinicaldecision based on assay results in conjunction withclinical symptoms and other examination results.
* 3. For the effects of an administered drug on themeasured value, carefully read the Precautions for
Use in the package insert of the drug, especiallythe section about the effects on laboratory testresults. Please also read carefully the “2.
Interfering Substances,” in the “ProceduralPrecautions” section, as well as “2. Precautions forAssessment” in the “Assessment of Assay Results”
section, of this package insert.
4. This product should be used only as directed in thispackage insert. Reliability of results cannot beguaranteed if there are any deviations from theinstructions in this package insert.
5. If the reagent accidentally comes in contact witheyes and/or mouth, rinse immediately with ample
water as first aid, and consult the doctor ifrequired.
6. Carefully read the operating instructions for eachtype of automated analyzers prior to using thisproduct. Parameters for each type of analyzers areavailable, and can be requested from SEKISUIMEDICAL CO., LTD. if required.
7. Perform a quality control test prior to assay toensure accuracy.

Procedural Precautions
1. Properties of Samples and Sampling Methods
1) Samples
Serum, plasma and urine may be used.
2) Storage of samples1)
The glucose level in whole blood deceases
over time. Separate cells from the sampleimmediately after collection of a blood
sample. When serum or plasma samples must
be stored after separation, store them at 2–10°C or at -20°C or lower.
Bring samples to room temperature (15–30C) before use.
Urine samples should be tested on the sameday.
2. Interfering substances
Assay results are not affected by free bilirubin (upto 50 mg/dL), conjugated bilirubin (up to 50mg/dL), hemoglobin (up to 500 mg/dL), or
ascorbic acid (50 mg/dL).
3. Others* 1) Always use Serum Multicalibrater (SEKISUI)
or Anaserum GLU standard solution forcalibration.
2) Precautions for assay range
If the concentration of sample exceeds assayrange, dilute the sample with saline and repeat
the measurement.

SRM917(NIST)
Precautions for Use or Handling
1. Precautions for Handling (to Ensure Safety)
1) All samples used in the test should be handled
as a material possibly infected with HIV, HBV,HCV, or other viruses. To prevent infection, use
disposable gloves and avoid mouth pipetting
during the test.
* 2) Sodium azide is added as an antiseptic agent inthe Enzyme Solution 1 and Enzyme Solution 2.
Therefore, if the reagent comes in accidentallycontact with eyes, mouth or skin, rinse
immediately with ample water as first aid, andconsult the doctor if required.
2. Precautions for use
1) This product should be stored as directed,
without freezing. Freezing can deteriorate thereagents, which can produce inaccurate results.
Therefore, avoid using the reagents which havebeen previously frozen.
2) Do not use expired reagents. Use of suchreagents cannot guarantee the reliability ofmeasurement values.
3) Do not replenish the reagents.
** 4) The product should be tightly stoppered andstored as instructed when not in use.
5) Do not perform the assay under direct sunlight.
3. Precautions for Disposal
1) Before disposal, used samples and theircontainers must be immersed in sodium
hypochlorite solution at a concentration ofgreater than 0.1% for longer than 1 hour or
autoclaved at 121ºC for 20 minutes.
2）To prevent infections from spilled samples orsolutions containing samples, wipe the spilledarea thoroughly with disinfectants such as
sodium hypochlorite solution at a concentrationof greater than 0.1%.
3) The reagents and treated samples should bediscarded as medical waste or industrial waste
according to the waste disposal regulations.
4) The reagents should be disposed of inaccordance with the Water Pollution Control act
or related regulations.
* 5) Sodium azide has been added as anantisepticagent in the Enzyme Solution 1 andEnzyme Solution 2. It can react with lead orcopper pipes to produce the highly explosive
metal azide. Therefore, the reagent should beflushed with large amounts of water during
disposal.
4. Other precautions
Do not use the containers for other purposes.
