Glucose stability -

Overall, as can be seen in Table 2 , regression analysis of the data revealed that at the half- and one-hour time points, there was good correlation between the three tube pairs.

We conclude that for the first hour after centrifugation, the values for glucose were comparable. Correlation Coefficients Pearson , Slopes, and Y-Intercepts for Tube Correlations at Different Sampling Times. At four hours, there was close agreement of the values determined in the red and gray tubes.

Glucose levels in both tube types were stable, as determined by the low coefficients of variation for red top tubes, mean value of 1. At four hours, the p values for the green top-red top tubes and the green top-gray top tubes correlations dropped to values much lower than the cutoff value of 0.

This result was contrary to what we expected on the basis of our previous finding [ 9 ] that glucose levels in green top tubes that were incubated for four hours at room temperature were found to correlate well with those found in corresponding red top and gray top tubes.

Significant deviations occurred after six hours, where there was a significant deviation between green top and red top tubes but good correlations between green top and gray top tubes. Only at two days were there significant deviations between green top tube and red and gray top tube values [ 9 ].

These results suggest that early centrifugation of green top tubes does not improve the stability of glucose measurements and, given the shorter time span for the decrease of values in the earlier centrifuged samples as in this study, may actually induce more rapid metabolism of glucose.

As found in our previous study [ 9 ], by day 2, glucose levels in the green top tubes decreased progressively in a continuous manner compared with those in the corresponding red- and gray-top tubes. However, in both studies, despite the significantly and increasingly lower values for glucose in the green top tubes as a function of time, the values continued to correlate with those of the red- and gray-top tubes.

Only the Y-intercepts differed by constantly increasing values over time. Thus, the glucose level for each sample in the green top tubes undergoes the same decrease over time, suggesting zero-order kinetics, possibly due to the enzyme e.

Importantly, this phenomenon was not observed in the gray top tubes, despite the fact that, like in the green top tubes, plasma is in contact with the cell layer.

There have been several reports that glucose levels in tubes containing sodium fluoride are significantly lower than those in serum separator tubes [ 4 , 5 ]. This has been attributed to the conversion of glucose to glycolysis intermediates, whose conversion to pyruvate from phosphoenolpyruvate is inhibited by fluoride.

Thus, significant levels of glucose would still be consumed. Our results indicate that glucose levels are stable in fluoride-containing gray top tubes and are the same in red top tubes with serum separator, which is in agreement with the results from another recent study [ 10 ].

These levels remain stable even when blood samples are held for four hours prior to analysis and are stable after centrifugation when the tubes are stored for long periods at least five days at 4 o C.

This suggests that the metabolic inhibitor, fluoride ion, effectively blocks glucose metabolism in the cell layer. Based on the results of the current and our previous study [ 9 ], we conclude that glucose levels are stable in centrifuged serum separator tubes and in fluoride-containing tubes stored at refrigeration temperatures.

Heparin-containing tubes with no serum separator and no metabolic inhibitor are not suitable for post-centrifugation storage, even at refrigeration temperatures. Copyright © by the testng Association of Clinical Scientists.

Say you take in simple sugars e. This might cause blood sugar to rise rapidly. And that often triggers insulin release, which can potentially affect endurance performance. This is caused by rebound hypoglycemia, depressed fat metabolism, and early depletion of glycogen stores.

Basically, a low Glucose Variability before exercise would mean an ideal source of glucose that stabilizes blood sugar and sustains muscle metabolism. Reducing Glucose Variability in the hours leading up to an event and then consuming a low-glucose response food immediately before exercise should provide a relatively slow rate of glucose absorption into the blood.

That provides a stable glucose supply to the muscle as your exercise progresses. And a relatively normal plasma insulin level allows you to preserve blood sugar availability and optimizes fat oxidation and catabolism while sparing glycogen reserves.
