The application of sigma metrics in the laboratory to assess quality control processes in South Africa.

Background: Laboratories use quality control processes to monitor and evaluate analytical performance in terms of precision and bias. Sigma metrics provide an objective assessment of laboratory quality using the total allowable error as an additional parameter.

Objective: This study aimed to determine the sigma metrics of analytes when using different total allowable error guidelines.

Galactorrhoea and Hyperprolactinaemia in a Non-Pregnant Female with Burns.

Galactorrhoea is the presence of breast milk secretion in non-pregnant or non-breastfeeding females. In females with galactorrhoea and amenorrhoea, hyperprolactinaemia is the most likely cause. Chest wall pathology is a known cause of hyperprolactinaemia, however there are few documented reports on galactorrhoea following burn injury to the chest wall.
