PROJECT
Validation of a dried milk spot card for ease of collection and storage of human milk
Taking a sample of breastmilk could be as simple as placing a drop of milk on a card
Breastmilk collection and analyses approaches to date has been based on collection into tubes with subsequent analysis on frozen samples. Human milk is a unique matrix requiring specific validation with issues for collection, storage, transport and analyses. This approach does not allow for storage of large numbers of samples or collections in remote areas.
Dried Milk Spots (DMS) provide an approach and collection system that solves these inherent problems. Although DMS collection systems exist for measurement of milk fatty acids and other compounds (IL-6 receptor blocker, antiretroviral therapy) there is a requirement to further develop these systems for multiple sensor nor DMS exists that targets the different milk components macronutrient or micronutrients relevant to infant growth and development.
Project goals:
- Optimise a Dried Milk Spot card for the collection of human milk
- Determine optimal storage conditions for the Dried Milk Spot care
- Develop methods to measure a suite of human milk components from the Dried Milk Spot card.
This PhD student project will involve the application development of assays to measure quantitatively the components of breastmilk placed on a card developed for collection of human milk samples.

Research team leader: Professor Donna Geddes
Prof Geddes is a lactation biologist, with a major focus on the mechanisms by which breastfeeding programme early and later life health outcomes. She is located at the School of Molecular Sciences at UWA where she measures milk composition in relation to infant outcomes. She leads a large group that works in the areas of human milk microbiome, metabolomics, biochemistry and physiology.
