Effect of Sample Volume Variation and Delay in Analysis on Plasma Glucose Concentration in Sri Lankan Healthy Adults

Table 2

Mean comparison of different analysis times at constant sample volumes.

Time between sample collection and analysis (hours)	Mean fasting plasma glucose concentration (mmol/L)
1	5.78^a ± 0.06
3	5.65^a ± 0.06
5	5.42^b ± 0.06

The values are expressed as mean ± SD. ^aNo statistically significant difference in mean fasting plasma glucose concentration between analysis after one hour of collection and analysis after three hours of collection ( > 0.05). ^bA statistically significant difference in mean fasting plasma glucose concentration between analysis after one hour of collection and analysis after five hours of collection ( < 0.001) and between the analysis after three hours and five hours after collection ( < 0.001).
