Miri is the only European equipment that analyzes human milk. The test sample is 10 milliliters and the result given within a minute and logged into the machine and then transferred to the project database. When the mother is exclusively breastfeeding, we ask for 10 ml. Manual hand compressed breast milk. The analyzed milk can´t be reused and is therefore destroyed.
