OBJECTIVE: The pre-analysis processing method of serum samples plays a very important role in the assurance of the quality of the entire test and the accuracy of the results. This study illustrates the importance of pretreatment methods of serum samples for the test results by comparing the effects of different pretreatment methods on the measurement of thyroid stimulating hormone (TSH) concentration in serum.

SUBJECTS AND METHODS: In this study, the concentrations of TSH of 37 patients’ serum, which were treated in six different ways including the reverse mixing times after blood collection, clotting time and conditions, centrifugal speed and time, were detected on Automatic Chemiluminescence Immunoassay Analyzer, and a comparative analysis of the different results was performed.

RESULTS: For serum samples containing coagulants, the test results were significantly affected if the samples were not reversed mixing after collection. The abnormal results would be obtained with insufficient coagulation time, low reaction temperature, low centrifuge speed and insufficient centrifugation time.

CONCLUSIONS: The pre-analysis processing of serum samples is the beginning of the entire inspection process. The quality of the entire inspection will not be guaranteed if the pre-analysis processing method is irregular. Therefore, clinical laboratories should pay more attention to the pretreatment process of samples to ensure the quality of the entire inspection process.
