Diagnostic test strips
Test strips SAMOTEST for urine analysis
- SAMOTEST 1 (acetone) 25 / 50 strips
- SAMOTEST 1 (glucose) 25 / 50 strips
- SAMOTEST 2 (glucose / acetone) 25 /50 strips
- SAMOTEST 3 (protein/ glucose /рН) 50 strips
Diagnostic test strips for urinalysis are ready laboratory reagents on plastic base for rapid in vitro diagnostics. Depending on reagent on the plastic base, test strips may be used for determination of glucose, ketones (acetoacetic acid) content in urine, specific gravity, presence of blood, pH value and other parameters.
The results of these tests may give information on carbohydrates metabolism (decomposition), renal and hepatic function, acid-base balance, and bacteriuria.
Test strips are packed with a desiccant to absorb moisture in a plastic container with screw cap. The strips are ready to use and need no preparation before analysis. The results are obtained by direct comparison of used indicator strip with a color block on container label.
To get results, you need no calculations or laboratory instruments.
| Tips for using | When used in laboratories |
Inportant!
The indicator strip is used only once.
Test strips for urinalysis are intended for in vitro use.
Do not touch test areas on indicator strips.
Storage
Store test strips at temperature from +15 to +30 °C out of reach of direct sunlight. Do not use the test strips after expiry date (see packaging)
Recommended procedure of use
All unused test strips should be kept in a sealed original packaging. Moving them to any other container for storage may cause deterioration in reactivity of indicator strips and make them unusable. Do not remove desiccant (silica gel sachet)from the container
Do not open container with strips, if you are not intended to make test.
Test strips must be used during three (3) months from the date of the first opening.
Test procedure
- You should take from container the number of strips necessary for immediate use, and then close the cap tightly.
- Immerse the reaction zone of indicator strip completely in fresh, well-mixed urine. Quickly remove the strip from the vessel with urine, because reaction zones on the strip can dissolve in urine.
- After taking the strip out, wipe its plastic edge by the edge of the vessel to remove excessive urine. Blot the longitudinal edge of the strip with a absorbent paper towel to remove excessive urine one more time and avoid crossing the edge of reaction zone (cross contamination of adjacent reaction zones).
- Compare each reaction zone with corresponding color blocks on the color scale and read the result exactly in certain time (the time of testing for each test zone is indicated on the container). Proper reading time of indicators is critical to achieve optimal results.
- Obtain results by direct comparison with the color scale on the container.
Note: All the reaction zones, except for those for white blood cells, can be read within 1-2 minutes to identify the differences between positive and negative urine. Changes in color after 2 minutes are of no diagnostic value.
Collection and preparation of samples (IMPORTANT!)
Urine should be collected into clean container and analyze it as quickly as possible after collection. Do not use the centrifuge! Urine preservatives are not recommended to be used. If testing cannot be done within one hour after sampling, the sample should be cooled immediately. The cooled sample may be used after bringing it to the room temperature.
Quality control (Lab information)
For best results, before using indicator strips should be checked with known negative and positive samples (controls) every time before the new analysis, and opening a new container with test strips.
