How to prepare for a Health MOT

People over-prepare for a Health MOT in the wrong direction. They stop tablets nobody asked them to stop, they arrive dehydrated for a blood draw, or they treat the visit as three separate hospital days. The clinic's own FAQ is shorter than the rumours. Advanced, Elite and Ultimate need a minimum four-hour fast. Your booking confirmation tells you whether to fast for your tier. Wear comfortable clothes, drink water, and bring the history that already exists on paper. A laboratory flag is still not a diagnosis after all of that work.

The Health Screening Clinic has run doctor-led screening at 117a Harley Street since 1984 and is CQC registered. Every Health MOT includes a GP consultation, a physical examination, blood tests, a report and a review. The default is one coordinated visit, not a split-appointment rule you have to invent. Imaging, when the tier includes it, is arranged as part of that same booking, and the Ultimate MRI is performed at our Harley Street imaging partner on a 3T scanner. Results are not handed over on the day, because laboratory work and, at higher tiers, radiology have to be reported before the review can be honest.

If you have a new, severe or worsening symptom, this is the wrong appointment. See a GP, use an urgent pathway, and use 999 or A&E for emergencies. Preparation will not convert a preventative package into acute care.

Essential: 45 minutes

The Essential Health MOT is £495. Allow 45 minutes. It runs Monday to Friday. Your booking confirmation tells you whether to fast for your tier. Arrive hydrated, since a well-filled vein is kinder than a dry one. Wear clothes you can move in for an examination and body-composition measurements.

Eat as you normally would that morning unless the clinic has given you a different instruction for a specific add-on. Continue regular medicines unless a clinician has told you otherwise in writing or on the phone. Do not build your own stop list from a forum. Blood pressure tablets, thyroid replacement, the contraceptive pill, inhalers and most long-term medicines are part of the history the doctor needs, not a problem to hide.

Essential is the baseline: consultation, examination, ECG, oxygen saturation, body composition, and a metabolic blood panel. There is no chest X-ray, no DEXA, no spirometry, no ultrasound and no MRI, so there is no imaging-prep puzzle. Bring previous bloods if you have them, a list of medicines and doses, and any clinic letters that explain an old flag. The same doctor usually reviews the results they took, a few working days later.

Advanced and Elite: four-hour fast, longer in the building

Fast for a minimum of four hours. Water is fine. The Advanced Health MOT is £999. Allow 1 to 1.5 hours. The visit adds a chest X-ray, spirometry, a VO2 max assessment, expanded thyroid and hormone work, and a DEXA scan when clinically indicated, plus four GP appointments across a calendar year. DEXA is not promised for every patient. If it is indicated after the assessment, the team will tell you. You do not need to arrive having googled a bone-density protocol of your own.

The Elite Health MOT is £1,850 for men and £2,095 for women. Allow 2.5 to 3 hours. Fast for a minimum of four hours. Women's Elite runs on Thursday and Friday specialist days; men's Elite is available Monday to Friday. Wear clothes that are easy to change out of if you are having pelvic or abdominal ultrasound, a smear, or a mammogram from age 40. Do not put deodorant, talc or lotion on the breast or underarm if a mammogram is booked. NHS breast screening gives the same practical advice, because residue can show on the film.

Continue regular medicines unless the clinic told you otherwise. Do not stop HRT, the pill, blood-pressure tablets or thyroxine because a hormone panel is on the menu. The doctor needs to read the hormones you are taking. If you are unsure about a medicine that must be timed with food, ask the clinic before the morning, rather than guessing and then needing a repeat draw.

Bring previous smears, mammograms, PSA figures, ultrasound reports and a note of your last menstrual period if that applies, because specialist imaging is easier to read against a baseline than as a first picture in a vacuum. Elite still includes chest X-ray and DEXA when indicated. It is not a full-body MRI day.

Ultimate: the same fast, plus MRI questions

Fast for a minimum of four hours. Water remains appropriate unless you are given a separate instruction for a particular sequence. The Ultimate Health MOT is £2,950 without gynaecology and £3,350 with it. Allow 3 to 4 hours, including 60 minutes of MRI covering brain, intracranial and carotid MRA, whole spine and torso. The MRI is performed at our Harley Street imaging partner on a 3T scanner.

MRI safety is a conversation, not a form you fill in after you are on the table. Tell the clinic before the day if you have implants, a pacemaker, an older aneurysm clip, a cochlear implant, metal fragments, or a history of metal in the eyes. Most modern joint replacements and dental work are acceptable, although the imaging team still has to check. If you are claustrophobic, say so. The scanner is a tube you lie in for about an hour. The team can talk you through what that involves. This article will not invent a sedation protocol or a split-visit rule. The default remains one coordinated booking.

Ultimate replaces chest X-ray and DEXA with that MRI protocol. It does not replace the examination or the bloods. You still need the four-hour fast for the laboratory work. You still need comfortable clothes for the clinic portion. You still need to continue regular medicines unless told otherwise. A clear MRI is not a cancer all-clear, and a cyst or disc change on the report is not a diagnosis.

What to bring, and what not to invent

Bring a medication list with doses, glasses or contact lenses if you wear them, inhalers, and any recent GP, clinic or hospital letters. Bring previous blood results rather than asking the doctor to guess whether a flag is new. If you have a pacemaker card, an implant card or an MRI safety letter, bring that for Ultimate.

Do not invent a two-day water-only fast. Do not invent a rule that you must stop all vitamins, all hormones, or all antihypertensives. Do not invent a split between bloods one week and scans the next unless the clinic has arranged that. Do not assume same-day results. Essential and Advanced reports typically take a few working days. Elite and Ultimate take longer where specialist reporting and MRI are involved. The review is the appointment that matters.

Tell the doctor about family history, smoking, alcohol, pregnancies, fractures, and the question you want answered. Hide the night sweats or the rectal bleeding and the MOT becomes an expensive normal, which helps nobody. Those symptoms also mean you should have used a GP or urgent pathway rather than a screening diary.

You do not need a GP referral. You do need to know which tier you booked. The fast, the duration and the specialist day all change with it.

Tips and tricks

Match the prep to the tier.

• Essential: 45 minutes, a fast only if your booking confirmation says so, hydrated, comfortable clothes.
• Advanced: minimum four-hour fast, 1 to 1.5 hours.
• Elite: minimum four-hour fast, 2.5 to 3 hours; women Thursday or Friday, men Monday to Friday.
• Ultimate: minimum four-hour fast, 3 to 4 hours including 60 minutes of MRI, and tell the clinic about implants or claustrophobia before the day.
• Write the medicine list the night before, including inhalers, contraceptives, HRT, supplements and anything you take only now and then.
• Put last menstrual period, last smear, last mammogram and last PSA on the same sheet if they apply.
• Take water with you for the wait after the fast.
• Ask, before the morning, about any tablet that must be taken with food.
• Arrive with enough time that a late train does not compress Elite or Ultimate.
• Leave space in the diary for the review.
• Keep NHS breast, cervical and bowel invitations.
• Preparation for a private MOT does not replace those programmes.

Things to avoid

• Do not guess the fast. Your booking confirmation tells you whether to fast for your tier.
• Do not skip the four-hour fast for Advanced, Elite or Ultimate.
• Do not stop regular medicines unless the clinic asked you to.
• Do not invent a stop list from a search result.
• Do not put deodorant or talc on the chest if a mammogram is booked.
• Do not wait until you are in the MRI changing room to mention a pacemaker, an implant or claustrophobia.
• Do not treat the MOT as a split-appointment puzzle.
• The default is one coordinated visit.
• Do not expect same-day unreviewed results.
• Do not book a screening MOT because you have a new cough, chest pain, a lump or anything else that is getting worse. That needs a GP or urgent pathway.

If you are ready to book with the matching prep note already in mind, current inclusions sit on the Health MOTs page, or you can contact The Health Screening Clinic on 020 7183 7056.

Frequently asked questions

Do I need to fast for a Health MOT?

Advanced, Elite and Ultimate need a minimum four-hour fast. For Essential, your booking confirmation tells you whether to fast. Water is appropriate unless you are given a separate instruction. Continue regular medicines unless the clinic told you otherwise.

How long should I allow?

45 minutes for Essential, 1 to 1.5 hours for Advanced, 2.5 to 3 hours for Elite, and 3 to 4 hours for Ultimate including 60 minutes of MRI. Women's Elite runs on Thursday and Friday specialist days; men's Elite is available Monday to Friday.

Should I stop my tablets before the blood tests?

Do not invent a stop list. Bring the medicines you take. Ask the clinic before the morning if a particular tablet must be taken with food. Hormone panels are read in the context of HRT, contraception and thyroid replacement, not in their absence.

Is the visit split across days?

The default is one coordinated booking. This clinic does not use an invented split-appointment rule. If imaging has to be timed separately for a safety or diary reason, the team will tell you.

What should I tell the clinic before Ultimate?

Implants, pacemakers, older aneurysm clips, cochlear devices, metal fragments, metal in the eyes, and claustrophobia. MRI is not suitable for everyone. The imaging team screens you before you are on the table.

Can I wear deodorant to Elite?

Skip deodorant, talc and lotion on the breast and underarm if a mammogram is part of the booking. Wear clothes that are easy to change for ultrasound or a smear.

I have a new symptom. Should I still prepare for the MOT?

No. New, severe or worsening symptoms need a GP or urgent assessment, not a preventative package. Use 999 or A&E for emergencies.
