separation of serum are performed to enable sample preparation. The use of
whole blood for sample analysis and automation of specimen can be done to
process the sample faster. Now, the sample tubes are transferred to the analyzer
room and loaded on the analyzer.
4.Processing of sample: The sample is processed before the measurement is done.
The processing includes the removal of the interfering substances from sample for
accurate testing on the analyte.
5.Reagent preparation and loading: All reagents used for analysis should be stored
at 4C until usage. The reagents are mixed if required and loaded on analyzer.
6.Sample measurement: During analysis on autoanalyzer, the samples react with
reagents and undergo chemical reactions under optimum conditions. The
measurements are processed automatically, and output signals are sent in the form
of results.
