Improve Phase

 Gannt Chart

Our team met in early August to plan and organise the Change of Control from Histology to Biochemistry of the Thyroid Antibodies. We designed a schedule for implementation of our new process using a Gannt Chart. This chart clearly defines the remaining timescale of our project.

Process Map 


Review of the new improved Process map demonstrates a considerable reduction in  manual input, thus reducing process variability.

 

Validation 

Test method validation is a critical part of any test method change, we are required to meet the requirements of ISO 15189. Samples were supplied by External Quality Assurance - RIQAS (www.riqas.com). Accuracy, within and between run precision were calculated. A-TPO is to replace TMA. Accuracy was established against samples with specific target values from RIQAS. Regression analysis was performed and r=0.998486 for Anti -TPO

Regression analysis performed on Anti-TG which will replace TGA in Histology was r= 0.995474

 Precision analysis is also detailed below.

This project remains on schedule and is projected to produce significant cost savings within the laboratory with minimal disruption to staff or customers.
