Table 1 Ten replicates weighing 1, 2, 3, 4 and 5 mg of hair from the same subject (50 samples in all) were extracted, measured and total within-assay coefficient of variation calculated
From: Cortisol in hair measured in young adults - a biomarker of major life stressors?
Weight of hair sample (n = 10 for each weight) | Coefficient of variation % |
|---|---|
1 mg | 46.2 |
2 mg | 16.1 |
3 mg | 12.4 |
4 mg | 13.6 |
5 mg | 7.9 |
