The kit is the tell. A serious home-visit operation standardises its bags the way an airline standardises its galley carts, and the contents follow the licence: diagnostic tools the doctor uses on every case, plus a controlled set of medications approved for administration on site. Expect a digital and infrared thermometer, blood pressure cuff, pulse oximeter, stethoscope, otoscope for ears, glucometer with strips, and rapid test kits, commonly strep, influenza and urine dipsticks. Many vendors also carry a portable ECG, which matters when the complaint is palpitations rather than a sore throat.
Time budget for setup is small but real: two to five minutes to sanitise hands, lay out a clean field on a table, and take a first round of vitals. If a doctor goes straight to prescribing without touching a single instrument, you have paid AED 300-800 for a conversation you could have had on video.
