When should I add an extra blood panel to a Health MOT rather than buying a bigger MOT tier?

You have usually arrived here because Essential already looks thorough, a friend mentioned an extra liver enzyme or an iron study, and the booking page then offers four Health MOT tiers plus a blood-test hub as if every extra tube were a small upgrade you should add on the day. That is the wrong picture. A Health MOT at The Health Screening Clinic already includes its published bloods by tier. An extra panel is worth discussing only when it would change the plan. If the next MOT tier already includes the question you brought, the honest purchase is that tier, not a bolt-on.

The clinic is at 117a Harley Street. Every personal MOT includes a doctor's examination, laboratory work, a written report and a review. Imaging, hormones and markers appear as you move up the menu. Individual named assays live on a different catalogue. This article will not invent add-on panel names or prices, because the clinic does not publish a priced extras menu, and any extra is confirmed with the clinic before booking.

What each MOT already includes, as package deltas

Start with the published bloods, because most people who ask for an add-on are asking for something the next tier already contains.

The Health MOT baseline, the Essential Health MOT, is £495. Allow 45 minutes. The bloods on that tier are a full blood count, kidney function, urate, calcium, phosphate and alkaline phosphatase, a full lipids profile, glucose, liver function, ESR, HbA1c, thyroid as FT4 and TSH, and iron. That is already a metabolic panel a doctor can read with an ECG and an examination. It is not a hormone clinic, a tumour-marker clinic or an MRI.

The Advanced Health MOT is £999. Allow 1 to 1.5 hours. It currently asks for a minimum four-hour fast. It includes everything in Essential, then adds advanced thyroid tests, iron with vitamin B12, vitamin D, and a hormone profile, plus chest X-ray, DEXA when clinically indicated, spirometry, a fitness assessment, and four GP appointments over a calendar year. If the question that made you hunt for an extra panel was hormones or a deeper thyroid look, Advanced is the package delta, not a custom tube on Essential.

The Elite Health MOT at £1,850 for men and £2,095 for women adds minerals, folate, CEA, and PSA or CA-125, with consultant ultrasound. Women's Elite runs on Thursday and Friday specialist days; men's Elite is available Monday to Friday. The Ultimate Health MOT at £2,950, or £3,350 with gynaecology, adds a full iron profile, a gluten-sensitivity profile, and, for women, HE4, CA-125 and a ROMA score, with 3T MRI of brain, intracranial and carotid MRA, whole spine and torso in place of X-ray and DEXA. If the question was markers, buy Elite, and if it was MRI, buy Ultimate, rather than trying to bolt those jobs onto a cheaper tier.

When an extra test is a conversation, not a catalogue line

Extra tests are discussed with the doctor when they would change the plan. That usually means a history, a medicine, a previous result, or a finding on the examination that the published panel will not address. It does not mean a wish to collect every number a laboratory can print.

A laboratory flag is not a diagnosis, because reference ranges are statistical intervals and an out-of-range result can be diet, a tablet, a one-off, or something that needs repeating. Adding more tubes because one flag felt unfinished is how people buy noise. The review appointment exists so a doctor who has examined you can say whether a result needs action, repeating, monitoring or no treatment at all.

If you arrive with a named extra in mind, say so when you book. If that named add-on is not on the current catalogue, the clinic confirms it before booking rather than inventing a price at reception. Do not assume a hospital wellness extras list, or a friend's private panel, maps onto this building.

Individual test names of the kind people search for when they want one enzyme, one kidney cluster or one iron study sit on the Blood London catalogue. They are not MOT add-ons on this site. Asking The Health Screening Clinic to price those named assays as MOT extras is asking it to be a different shop.

Buy the next tier when it already includes the question

The useful rule is simple, although the menus are not. If you want hormones, the published answer is Advanced, not Essential plus a hoped-for extra. If you want tumour markers read with sex-specific ultrasound, the published answer is Elite, not Advanced plus a marker. If you want MRI of brain, MRA, whole spine and torso, the published answer is Ultimate, not Elite plus a scan.

Those are package deltas. They exist because the extra bloods on a higher tier are meant to be read with the extra pictures and the extra time. CEA on a PDF without ultrasound and without a doctor who has examined you is a weaker investigation than CEA inside Elite. A full iron profile without the rest of Ultimate is a different job from Ultimate.

The package quiz is a practical way to see which tier already holds the question, because it is a chooser rather than an extras list. It is not a diagnosis, and it is not a promise that a longer panel is safer.

UK screening principles still apply when you pay. The UK National Screening Committee describes screening as identifying apparently healthy people who may have an increased chance of a condition, with further tests often needed rather than a result counting as disease. NHS pages on blood tests are plain that results are interpreted with the rest of your health. Paying for more tubes does not sit outside that logic, and NICE suspected-cancer guidance uses markers such as PSA and CA125 inside defined symptom-led pathways, not as general add-ons you can buy to be sure.

There is no priced extras menu

The clinic's pages point you toward full-body MOTs, cognitive screening and cancer screening rather than a priced add-on catalogue, which is why this article will not reprint invented panel names, and why confirmation with the clinic comes before any extra is booked.

If your only goal was a standalone blood draw without a Health MOT, that is a different appointment from the four MOT tiers, such as full body bloods. If your goal was a MOT, choose the tier first. Review whether any extra would change the plan after that choice, with the doctor, not from a brochure you have written yourself.

New, severe or worsening symptoms still need a GP or urgent assessment. A missing enzyme on a wish-list is not a reason to delay chest pain, a new lump, or a bowel habit that has shifted and stayed shifted. Use 999 or A&E for emergencies.

Tips and tricks

• Choose the MOT tier by the question, then ask whether anything still missing would change the plan.
• The published deltas are simple: hormones sit on Advanced, markers on Elite, and MRI on Ultimate.
• Say if you have a recent panel from another clinic, because repeating the same chemistry six weeks later is usually noise.
• Bring the printout.
• Fast only if the clinic instructed you to: Advanced and above currently ask for a minimum of four hours. Your booking confirmation tells you whether to fast for your tier.
• Continue regular medicines unless you were told otherwise.
• If you have a named extra in mind, ask the clinic to confirm it before you book, because a test that is not on the current catalogue should not be priced on the doorstep.
• Use the package quiz if you are choosing a tier rather than designing a custom panel.

Things to avoid

• Do not treat a Health MOT as a blank form onto which every laboratory test can be added.
• Do not buy Essential and then try to recreate Advanced, Elite or Ultimate with extras.
• Do not invent add-on panel names or prices from another clinic's menu.
• Do not read a laboratory flag as a diagnosis, and do not buy more tubes because one number sat outside a reference range.
• Do not skip a GP because you have a screening date.
• Do not expect individual named assays from another catalogue to be MOT extras here.
• If you have already chosen a tier and still want an extra test, call 020 7183 7056 to confirm it before booking.
• Confirm any extra with the clinic before booking.

For what each tier already includes, read what a full body MOT includes. For tumour markers specifically, see tumour markers in a MOT.

Frequently asked questions

When should I add an extra blood panel to a Health MOT?

When a doctor agrees it would change the plan, after you have chosen a tier. If the next MOT already includes the question, buy that tier instead.

Does Essential include hormones or tumour markers?

No. Essential is the £495 baseline with core metabolic bloods, an examination and an ECG. Hormones sit on Advanced and markers on Elite.

Can I add MRI as a blood-test extra?

No. MRI of brain, MRA, whole spine and torso sits on Ultimate. It is a package delta, not a bolt-on tube.

Where is the priced add-on catalogue?

The clinic does not publish a priced extras menu. If a named add-on is not part of your tier, the clinic confirms it before booking.

Are individual tests such as a single enzyme or iron study MOT add-ons here?

Named individual assays sit on a different catalogue. They are not printed as MOT extras on this site, and this article will not invent them.

Is an out-of-range blood result a diagnosis?

No. A laboratory flag is a statistical finding for a doctor to read with the examination, history and any pictures, not a disease name.

What if I have a new symptom?

Book a GP or urgent assessment rather than adding tubes to a preventative MOT. Use 999 or A&E for emergencies.
