Visual test strips 'Urireal-1��' # 100

100 tests per box

PURPOSE

Indicator test strips URREAL-1rN are intended for qualitative and semi-quantitative in vitro" (in vitro) determination of pH in urine and its falsifications.

Indicator test strips are used for clinical laboratory diagnostics (clinical and diagnostic laboratories of medical institutions, treatment-and-prophylactic institutions), research practice.

The determination makes it possible to control the physical and biochemical parameters of urine pH, as well as establish the fact of the authenticity of urine.

The sensor element for determining the pH (acidity) is immobilized by the pH indicator bromothymol blue and serves to determine the acidity in urine or its counterfeit (bromothymol blue, not less than 2.5% buffer (dry), not less than 96% and non-reactive components).

The method for determining pH is based on the use of an indicator, which changes color depending on the pH of the sample.

Comparing the color of the sensor element for pH with a reference on a color scale, its value in urine or its counterfeit is estimated.

Comparing the color and its intensity with the standard on the color scale, determine the pH (semi-quantitative determination).

The sensitivity of the touch zone is 0.0 units.

Indicators of pH (acidity) of urine are in the range from 4.0 to 8.0 units.

(in some exceptional cases, urine pH values ​​can range from 4.0 to 9.0 units).

In the range of pH values ​​in the sample above 12.0, the sensor zone of the test strip practically does not change color in the direction of its increase.

False positive and false negative test results are detected in falsified urine with a total hardness of up to 2.0 meq / l.

Potential risk class - 2a.

Test strips are for single use only.

DEFINITION

To determine, use freshly collected (no more than 2 hours before analysis) urine in a clean dish, not centrifuged and thoroughly mixed.

1. Control at a temperature (+ 15– + 30 ° С).

2. Open the case or open the bag, remove the indicator strip from it.

If the indicator strips are packed in a pencil case, immediately close the latter tightly with a lid.

3. Immerse the sensor strip completely in the urine.

After 1-2 seconds, remove the indicator strip and remove excess urine on the sensor element by gently touching the rib of the strip to clean filter paper (clean paper towel, paper towel, toilet paper, etc.) for 2-3 seconds.

4. After 15 seconds from the moment the sensor is immersed in urine, compare the color of the sensor with the color scale on the package label under good lighting conditions.

!

Registration of the obtained analysis results can be carried out visually.

!

Do not compare the color of the sensor element with the color scale in direct sunlight.

!

During the test, do not touch the sensor element of the Test Strip with your hands.

A semi-quantitative determination is carried out by comparing the color of the sensor element with the corresponding color fields of the scale.

Changes in color, which can only occur at the edges of the sensory area (edging), are not diagnostic.

!

Strict adherence to the instructions for use is essential to obtain reliable results!

CONDITIONS OF STORAGE, OPERATION AND DISPOSAL OF THE PRODUCT

Test strips should be stored in the manufacturer's packaging in a dry place at temperatures up to 30 ° C (in the absence of acid, alkali and organic solvent vapors) for the entire shelf life of 24 months.

Biochemical research of water should be carried out at a temperature of + 10- + 35 ° C.

Improper storage and use will result in the loss of functionality of the test strips.

Keep out of the reach of children.

It is necessary to protect the indicator strips from high humidity and direct sunlight.

Avoid direct sunlight on the color scale.

Each indicator strip is designed for one determination.

After opening the case, the indicator strips should be used within no more than 5 months.

The test strip taken out of the package should be used for analysis within 15 minutes.

Do not use after the expiration date.

In case of testing after use, all components and packaging should be thrown into the waste container.
