How long do the appointments or visits last?

The length and number of study visits depend on the specific trial. Typically, visits last at least 30 minutes, but some may take a few hours depending on the procedures involved. 

Your first visit—known as the screening visit—is usually the longest. This is because it includes the informed consent process, a review of your medical history, collection of lab samples, and study-related assessments or questionnaires. 

Before you decide to take part, we’ll provide clear details on how long each visit is expected to take, how often you’ll need to attend, and the overall duration of the study. Your time is valuable, and we aim to make each visit as smooth and efficient as possible.
