Siemens Ictotest Reagent Tablets
The Ictotest tablets, based on the diazotization reaction, are utilized as a confirmatory assay for the presence of urinary bilirubin when a frontline test (i.e. urine strip or another semi-quantitative method) has provided a positive bilirubin result. The Ictotest reagent tablets can be used to rule-out the presence of interfering substances that may cause a false positive result.
- Place a square of the absorbent test mat supplied onto a paper towel. Using either side of the test mat will produce expected results. Please 10 drops of urine onto the center of the test mat.
- Shake one Ictotest Reagent Tablet into the the bottle cap and transfer the tablet to the center of the moistened mat. Do not handle tablet with your fingers. Recap the bottle promptly.
- Place one drop of distilled water onto the tablet. Wait 5 seconds, then place a second drop of distilled water onto the tablet so that the distilled water runs off the tablet onto the mat.
- Observe the color of the mat around and under the tablet at 60 seconds.
RESULTS: Results with Ictotest Reagent Tablets are negative if no blue or purple color develops on the mat within 60 seconds. If a blue or purple color develops on the mat or under the tablet within 60 seconds, the result is positive. Pink or red color should be ignored.
POSITIVE RESULT: The presence of a blue or purple color on the mat indicates that bilirubin is present. The illustration below shows typical positive results. The color gradient shows a sample range of color for a positive result.
NEGATIVE RESULTS: The absence of blue or purple color on the mat indicates that no bilirubin is present. A slight pink or red color should be ignored. The illustration below shows typical negative results. The color gradient shows a sample range of color for a negative result.
