Internal Standard Zone

The Internal Standard corrects for membrane variability and provides an internal validation of the assay. For instance, membrane variations that cause a lower-than-normal reading at the Internal Standard would have the same effect at the Detection Zone.
 
By calculating the final test result as a ratio between the two measurements, the RAMP^® System automatically accounts for such variations.
 
No reading at the Internal Standard indicates that the test was not successfully completed, and acts as an automatic quality control check.
 
In less than 15 minutes, depending on which assay is being run, the test result appears on an LCD readout. The result can also be stored, printed, or uploaded to a laboratory or hospital information system.
 

 

Results

 
The Reader detector separately measures the amount of fluorescence emitted by the complexes captured at the Detection and Internal Standard Zones.
 
To establish a quantitative reading, the Reader calculates the ratio between the fluorescence in the two Zones.
