To assist the diagnosis of diseases and disorders and to monitor therapy,a wide range of clinical tests had been developed.The need for investigations is increasing with the growth of population and increase of diseases.To get fast results on a large number of specimens,it is becoming inevitable to replace manual methods.This could be done by autoanalysers.With the help of autoanalysers an increased volume of samples can be processed rapidly and with reproducible results.To maintain the quality of results, samples of known values will be run along with every batch of test samples.
Advantages of an autoanalyser
⭐ Accuracy is more when compared with manual method.
⭐Large number of samples may be processed in minimal time.
⭐Two or more assays may be performed simultaneously.
⭐ Calculations are not required.
⭐Invaluable for accurate determination of red cell indices.
Disadvantages of an autoanalyser
⭐It is impractical for small number of specimens.
⭐ Instruments may fail occasionally.
⭐ Additional training of the staff regarding the working, maintenance and potential problems of the machine is needed.
⭐Erroneously increased or decreased results due to interfering factors.
⭐They are expensive.
Parameters to be analysed by an autoanalyser
Autoanalyser can be used to estimate parameters such as glucose, protein,albumin, creatinine,blood irea nitrogen, sodium, potassium, chlorine, transaminase,lactic dehydrogenase, bilirubin,inorganic phosphate, Calcium, cholesterol,uric acid,phosphatases and bicarbonate.
