Comparison of Serum Stability Against Uric Acid and Glucose

The selection of tools, especially the use of vacutainer tubes, affects the results of the
examination to determine the stability of serum from plain vacutainer with vacutainer
separation gel on the quality of uric acid and glucose test results. This study used an
experimental design. The study took blood samples of 3 ml each in SST vacutainer and plain
vacutainer serum. The mean uric acid levels using plain vacutainer and SST vacutainer were
4.5875 ± 0.59048 and 4.9250 ± 0.56318, respectively. The mean glucose levels using plain
vacutainer and SST vacutainer were 90.64 ± 12.33 and 94.12 ± 13.30, respectively. Uric acid
and glucose levels using gel-separated vacutainer were higher than uric acid levels using plain
vacutainer. There was a significant difference in uric acid levels between regular vacutainers
and SST vacutainers, similar to glucose levels (p = 0.000, p = 0.000). Uric acid and glucose
levels using SST vacutainer were higher than uric acid levels using plain vacutainer. The
following types of vacutainer separator gel and plain vacutainer affect the quality of uric acid
and glucose test results
