The new arrival who just collected the keys
You have an Emirates ID, a tenancy contract, and no idea where your health records from your last country actually live. This is the single best moment to establish a baseline, because every future result becomes more useful when there is a 'before' to compare against. The sensible starter set is a CBC (complete blood count — red cells, white cells, platelets), a fasting lipid profile, HbA1c (your average blood sugar over roughly three months), and vitamin D.
New arrivals also face a practical snag: no local doctor yet. If anything in the panel comes back flagged, you want a GP appointment within a week or two, not a screenshot sitting in your camera roll for six months. Booking through an app like tamam helps here mainly because you can compare several licensed home-healthcare vendors with their AED ranges side by side before you know which names are reputable, rather than gambling on the first search result in a country you moved to last month.
