Can anyone take the test (what are the limitations)?

This test is intended for people aged 18 or older.

This test is not intended for people who have received blood transfusion or gamma globulin blood derivatives (such as intravenous immunoglobulin preparations) within the last six months.

If you are taking blood-thinning medications or you are suffering from a blood clotting disorder, discuss the safety of taking the test with your attending physician. Children and young adults have a specific IgG glycan profile; therefore GlycanAge test is not recommended for anyone younger than 18 years of age.
