If you have submitted your screening test to Discovery Health, Vitality should automatically pick it up and allocate your points (e.g. dentist visit or glaucoma eye test).
If you have paid cash for the test/visit you will need to manually submit via the website.
Log in and click on Vitality, click on "Track and earn points" click on the screening you have just done, then on the right hand side, click on "Claim Vitality points". They will then ask you for the date you went and ask you to upload the file of proof.
