Longetic pulls together every lab and record you’ve had, follows how Apolipoprotein E (ApoE) changes over time, and explains what’s shifting — so you walk into your next appointment prepared, with reminders for retests along the way.
What is Apolipoprotein E (ApoE)?
A protein that helps the body handle fats and cholesterol in the blood, and comes in a few common genetic forms.
Apolipoprotein E helps clear cholesterol and triglyceride-rich particles from the bloodstream, and it exists in several inherited variants that influence how efficiently this happens. Some ApoE forms can be associated with higher cholesterol and greater cardiovascular risk, while others can be associated with lower cholesterol, and certain rare patterns are linked with specific inherited lipid disorders. This is a specialized marker, measured as a protein level or a genotype, and it is not part of routine testing.
