Analytical goals for P-bilirubins

Analytical goals for P-Bilirubins (total) were assessed on the basis of biological variation and "medical needs". Goals for analytical accuracy were from 0.01 to 0.18 expressed as relative deviations. Goals for analytical precision were 0.11-0.12 expressed as relative standard deviations. Using a reference method, we found that the average values of clinical laboratories deviated from 0.03 to 0.10 from reference method values. The average intra-laboratory precision was 0.088, i.e. within the goal limits.
