Once you have downloaded and registered on the H&B&Me app using the same email address you previously used for Ivie, you'll be asked to either complete the biological age questionnaire, register a test kit or skip. If you just want to view your blood test results, you can click on the skip button. This will take you to the home screen, where you can view your previous blood test results by clicking on the Test icon at the bottom of the screen. 

You could always do the biological age questionnaire first and then go and view your previous blood test results by clicking on the Test icon at the bottom of the home screen once you have finished the 3-4 minute questionnaire.
