The referral laboratory where LifeLabs sends Copeptin testing to will discontinue parallel Osmolality testing due to concerns about pre-analytical factors affecting accuracy of osmolality results. This will go into effect on Dec 16, 2021. The reports will continue to provide comments that can be used to interpret copeptin results independent of osmolality. However, if you require osmolality tested, please order it together with copeptin.
ATTENTION TRAVELLERS: If you are looking to register for travel-related COVID testing or access your FlyClear results, here.
