Pre-Employment Medical: What to Expect

A pre-employment medical answers one narrow question: can this person do these specific tasks, in this specific environment, without harm to themselves or others. It is not a health MOT, it does not screen you for cancer, and a normal result does not mean you are well.

Understanding that framing removes most of the anxiety. The examiner is comparing you against a job description, not against an ideal.

What usually happens#

Expect thirty to sixty minutes, in this rough order.

A health questionnaire. Past illnesses, surgery, current medicines, allergies, previous exposure to noise, dust, chemicals or vibration, and any earlier work-related illness. Answer it accurately.

Basic measurements. Height, weight, waist, pulse, blood pressure, sometimes a urine dipstick.

Vision. Distance acuity with a standard chart, near vision, and color vision using Ishihara plates where the role depends on color: electrical work, some driving and control-room roles.

Audiometry if you will work at or above a noise action level. Under OSHA rules a baseline audiogram is required within six months of first exposure at or above 85 dB(A) as an eight-hour average. UK regulations set a lower action value at 80 dB(A) daily.

Spirometry if you will wear respiratory protection or work with dust, flour, isocyanates, welding fume or similar.

Musculoskeletal assessment for manual handling roles: spine movement, grip, shoulders, previous injury.

Drug and alcohol screening in safety-critical work, if the company policy says so and you have consented.

Roles involving confined spaces, heat work, working at height, forklift or crane operation, or night shift often add specific elements. An ECG, a functional capacity test, or a review of medicines that cause drowsiness.

Why the baseline tests matter to you#

This is the part people miss. A baseline audiogram and a baseline spirometry are the evidence that your hearing and lung function were normal on day one. If a hearing loss or a drop in lung function shows up in year six, that first test is what turns it from an argument into a documented occupational injury.

Keep your own copy of every baseline and every annual result. Occupational health records follow the employer, not you, and jobs end.

Confidentiality, in plain terms#

Two records exist. The clinical record, held by occupational health, contains your history and results. The management report contains an opinion, fit, fit with adjustments, temporarily unfit, unfit, and the practical restrictions that follow.

Managers see the second. They are not entitled to the first. If someone in HR is quoting your diagnosis back at you, something has gone wrong.

How to prepare#

Bring a list of your medicines, your glasses or contact lenses, and any hearing aids. Avoid heavy caffeine, nicotine or a hard gym session in the hour before, since all three push blood pressure up. Sleep normally the night before. If you have white-coat anxiety, say so at the start. A single high reading should trigger a repeat, not a rejection.

Where to take this next#

Most of what gets flagged at these assessments in office and light-industrial workforces is musculoskeletal: an old back injury, a stiff neck, wrists that ache by Friday. The full guide to desk-work back and neck pain explains what is worth fixing before it becomes a restriction on your record.
