Reason: Because it involve the Turn around time.
Not every analyser designed equally. What I want to share here is, some analyser is able to reload the reagent during half way of the process while some analyser will need to wait it completely stop functioning before we can reload the reagent.
For the analyser we use in our laboratory, we have to wait for it to stop completely before reload the reagent. Therefore it might prolong the TAT if the reagent inventory is not checked before running the test.
Example:
The on board urea reagent has only 20 tests remaining, while there are 30 samples to be investigated.
Hence, we still need another 10 or more units of the reagent volume.
If we have a reagent checking earlier, we can reload the reagent on the spot and will not be facing the reagent shortage during the process.
How the reagent shortage affect the TAT?
Here is an example,
There are 30 samples in the first batch and still, there are new samples coming in.
We have no choice but to left the new samples aside to reload the new reagent.
The analyser will take around 20 minutes to stop completely before we are allowed to reload the empty reagent.
However when there is an emergency, you have to stop the analyser by force in order to reload the new reagent. Even by doing so is able to shorten the TAT, it will still take some time to process. After we force the analyser to stop and reloaded the new reagent, we will need to update the inventory and run the calibration as well as the control based on the SOP ( Standard Operating Procedure ).
Suggestion/Solution
- Strongly recommended to check the reagent inventory before start the work.
