A pre-employment physical is a medical examination that an employer requires after offering you a job but before your first day of work. Its purpose is to confirm you’re physically capable of performing the job safely. What the exam includes varies widely depending on the role: an office job might only require basic vitals and a drug screen, while a commercial truck driver or construction worker will face a much more detailed evaluation with specific pass/fail thresholds.
What Happens During the Exam
A standard pre-employment physical starts with the basics: height, weight, temperature, pulse, breathing rate, and blood pressure. The provider will examine your head and neck, listen to your heart and lungs, check your abdomen, and assess your spine and joints. For most positions, this general once-over is the core of the visit.
Beyond the baseline, the exam typically includes:
- Vision testing: Near and far visual acuity, depth perception, peripheral vision, and color recognition. Many physically demanding jobs require at least 20/40 vision in each eye, with or without corrective lenses, and the ability to distinguish red, amber, and green.
- Hearing testing: An audiometry screen measuring your ability to hear specific frequencies. For roles governed by federal standards, average hearing loss in your better ear cannot exceed 40 decibels across key speech frequencies.
- Musculoskeletal check: The provider evaluates your hands, arms, legs, feet, back, and neck for any impairment that would interfere with the physical demands of the position.
- Urinalysis and blood work: A urine sample and fasting blood draw may be used to check kidney function, liver enzymes, blood sugar, and blood cell counts.
Some employers also require a resting electrocardiogram (EKG) to screen for heart rhythm problems, lung function testing where you blow into a device that measures airflow, and a baseline chest X-ray. These are more common in jobs involving physical exertion, hazardous materials, or respiratory risks.
Drug Screening
Most pre-employment physicals include a urine drug test, and the most common version is a 10-panel screen. It checks for amphetamines, cocaine, marijuana (THC), opiates like codeine and morphine, PCP, barbiturates, benzodiazepines, methadone, methaqualone, and propoxyphene.
Detection windows vary by substance. Cocaine and amphetamines typically show up for 2 to 5 days after use. Opiates are detectable for up to 4 days. Marijuana has the widest range: anywhere from 1 to 30 days depending on how frequently you’ve used it. Benzodiazepines can linger for 2 to 14 days depending on the specific medication. If you take a prescribed medication that might trigger a positive result, bring your prescription information so the reviewing physician can account for it.
How Physical Exams Differ by Industry
Not all pre-employment physicals are the same. The job dictates the exam.
Commercial vehicle drivers face one of the most regulated versions. The Department of Transportation (DOT) medical certificate requires blood pressure below 140/90 for a full two-year certification. If your reading falls between 140/90 and 159/99, you can only be certified for one year. Readings between 160/109 result in a three-month temporary certification, giving you time to bring your blood pressure down. Anything above 180/110 is an automatic disqualification until it’s controlled.
Workers exposed to specific hazards face mandatory medical surveillance under OSHA rules. Jobs involving lead, asbestos, cadmium, benzene, noise above certain levels, and respiratory protection all trigger required medical exams, sometimes before you start and then at regular intervals throughout employment. These aren’t generic physicals. They target the specific organ systems that the hazard affects.
Functional Capacity Evaluations
For physically demanding jobs like warehouse work, firefighting, or construction, your employer may require a functional capacity evaluation (FCE) in addition to or instead of a standard physical. This is a hands-on performance test, not a stethoscope-and-blood-pressure visit. You’ll be asked to lift, push, pull, grip, and move through job-specific motions while the evaluator measures your strength, range of motion, and endurance.
According to Johns Hopkins Medicine, an FCE typically takes about four hours, though for some occupations it can extend to two consecutive days of up to eight hours each to simulate a realistic work environment. The facility uses equipment designed to replicate the exact movements your job requires.
Legal Protections You Should Know
The Americans with Disabilities Act places strict rules on when and how employers can require medical exams. Before making you a job offer, an employer cannot ask disability-related questions or require any medical examination at all. This is true even if the questions seem job-related. The physical can only happen after you receive a conditional job offer.
Once that offer is made, the employer can require a full medical exam, but there’s a catch: they must require it of every person entering the same job category, not just you. An employer can’t single out one candidate for a physical while skipping it for others in the same role. If the results reveal a condition, the employer can only withdraw the offer if the condition genuinely prevents you from performing essential job functions, even with reasonable accommodations.
Your medical details also stay between you and the examining provider. The employer receives a determination of whether you’re fit for the role, along with any work restrictions, but they don’t get your full medical chart. Your records must be kept in a separate confidential file, not in your general personnel folder.
Who Pays for It
This depends on timing. According to a U.S. Department of Labor opinion letter, if the exam happens before an employment relationship is established, the employer has no legal obligation under federal law to cover the cost or compensate you for the time. In practice, though, most employers do pay because they’re the ones requiring it.
If an employment relationship already exists when the exam occurs (for example, you’ve signed paperwork or started orientation), the employer must cover the cost to the extent that making you pay would drop your wages below minimum wage. The time spent at the exam also becomes compensable work time in that scenario. Some states have their own laws requiring employer payment regardless, so the rules in your state may be more protective than the federal baseline.
What to Bring and How to Prepare
Arrive with a photo ID and your insurance card if applicable, though most employer-paid exams won’t bill your insurance. Bring a list of current medications, including dosages, and any relevant medical records like a recent vision prescription or documentation of a chronic condition. If blood work is part of the exam, you may be asked to fast for 12 hours beforehand.
Wear comfortable clothing that allows you to move freely, especially if a musculoskeletal assessment or functional testing is involved. If you wear glasses or a hearing aid, bring them. Most vision and hearing standards allow corrective devices, and your results will be measured with them in place. The entire visit typically takes 30 minutes to an hour for a standard physical, longer if functional testing or specialty screenings are included.
