Analytical goals for P-bilirubins

Area of Science:

• Clinical Chemistry
• Analytical Biochemistry

Background:

• Establishing analytical goals for laboratory tests is crucial for ensuring clinical utility.
• Total P-Bilirubins are important biomarkers in diagnosing and monitoring various conditions.

Purpose of the Study:

• To assess analytical goals for total P-Bilirubins based on biological variation and medical needs.
• To evaluate the performance of clinical laboratories against these established analytical goals.

Main Methods:

• Analytical goals for accuracy (relative deviation) and precision (relative standard deviation) were defined.
• A reference method was used to compare clinical laboratory values.
• Intra-laboratory precision was calculated.

Main Results:

• Analytical accuracy goals ranged from 0.01 to 0.18 relative deviation.
• Analytical precision goals ranged from 0.11 to 0.12 relative standard deviation.
• Clinical laboratories showed average deviations from 0.03 to 0.10 and average intra-laboratory precision of 0.088, meeting the defined goals.

Conclusions:

• The established analytical goals for total P-Bilirubins are achievable by clinical laboratories.
• Laboratory performance in terms of accuracy and precision for total P-Bilirubins meets the defined analytical goals.
