Table 1.

Precision of TMAO concentrations measured in 6 pooled plasma samples with different levels over a span of more than 20 days.

Pooled plasma	mean ± SD	Intra-day CV%	Inter-day CV%
1	0.82 ± 0.05	6.4	5.8
2	1.68 ± 0.10	4.1	9.9
3	2.95 ± 0.11	3.1	5.8
4	2.44 ± 0.09	2.7	6.1
5	66.8 ± 2.1	2.1	5.2
6	102.4 ± 3.3	1.3	6.2

The calculated mean, SD, intra-day CV% and inter-day CV% are given. For each of the 6 different plasma samples, a cluster of 4 determinations is presented as they were run on eight separate days (32 determinations total for each pooled plasma sample).
