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.
Vitamin D deserves special mention because it is the great UAE paradox: a country with year-round sun where the majority of residents test deficient or insufficient. The reasons are mundane — air-conditioned indoor life, cars, covered clothing, and deliberate sun avoidance from May to September. If you have been here more than six months and have never tested it, assume nothing about your level. Deficiency is common enough that many doctors here check it as routinely as cholesterol.
