Turbodensitometry is the name given to the method used by our analyzers to detect the formation of a clot. The principle elements of the instrument are a micro-controller that tracks and controls the functions of our instruments.
The above picture is a simplified block diagram of how the analyzer works. The micro-controller checks the temperature of the reagent block & measuring well. If the temperature is not at 37 degrees C then the heating elements are activated to raise the temperature. The micro-controller tests and adjusts the light level passing through the measuring well to maintain a stable baseline, by doing this our instrument is able to detect clots in either more or less optically dense reagents. Another benefit of this design is the ability of the micro-controller to automatically start the timer upon injection of the start reagent into the measuring well, this makes the results more accurate and repeatable.
As the clot is formed the electronic eye attached to the micro-controller sees the light baseline change. Once the baseline has changed past its set point the timer is stopped, calculations are performed and results are sent to the numeric display. |
