Campus discussion :D
Department: Biochemistry
Topic: Processing of specimens and LX PRO Analyser
Hey all, i'm in biochemistry lab now.
I'm going to talk about the processing of biochem samples and about the LX PRO Analyser.
Firstly when samples are reeceived in the biochem lab, the med tech has to check a few importatnt things.
1. Patient's name
2. Patient's IC no
3. Accession no
4.Tests ordered and collection priority: Urgent or routine
Samples are being spinned down as the serum is the one tested by the Analyser.
Samples that are in the primary tube could be directly placed on the rack with the adaptor. While the samples in the microtube should be proceed differently. The serum should be pipetted into the sample cup and a LIS acession label should be put on the sample cup to allow the analyser to read it.It must be checked that there are no bubbles in the sample cup as it will affect the results.Then only should it be placed on the rack with the adaptor.Rack is then placed on the autoloader of the Beckman LX PRO analyser.
Beckman LX PRO analyser is a machine that conducts all kinds biochemical tests.
It includes urea, glucose, creatinine, albumin, uric acid, total protein, Phospurous, magnesium, gentamycin etc.
Before patients' samples could be run, QC have to be done every morning.
The level of the modular chemistry agents should be checked. The ones with low levels should be loaded.
Next calibration has to be done.The analyser analyzer performs the calibrations. It automatically checks the calibration and produces the data at the end of the calibration. Error codes will be printed out against failed calibrations. Troubleshooting has to be done against failed calibrations and only if calibration passes,we can proceed to run controls.
QC schedule plan has the chemistries to do the QC run. Controls should be mixed well and then dispensed at the required volume into the specified control into the sample cup. Analyzer runs all the chemistries for that control. Troubleshooting has to be done for flagged chemistries. Control check has to pass before proceeding to run patient samples.
That's it.It's not very difficult, pretty easy.
Cya all:D
