Medical Examination

The MEPS medical examination is probably the most thorough physical you'll ever receive, and it's completely free. The military needs to know whether you can handle the physical demands of service, from basic training through deployments, without your health putting you or others at risk. This section walks through every component, the actual standards, and what happens if something comes back flagged. (If you haven't yet, start with preparing for MEPS and the MEPS experience for the general flow.)

One rulebook, and a database that remembers

The medical standards come from a single document: DoDI 6130.03, Volume 1, currently on Change 5 (May 28, 2024) (1). Every branch uses the same disqualifying standards at MEPS, though each service sets its own waiver tolerances. The Air Force is the most selective, as you'll see below.

One number puts the stakes in perspective: roughly 77% of Americans ages 17 to 24 are ineligible for military service when you combine all disqualifying factors: obesity, drug use, medical conditions, mental health, education deficits, criminal history (2). That doesn't mean 77% fail this exam, but the screening is genuinely rigorous. About 26% of all Air Force accessions in FY2023 required some type of waiver to get through (3).

The other force shaping today's process is MHS Genesis, the military's electronic health records platform, deployed to all 67 MEPS in March 2022 (4). Once you sign the consent form, Genesis reaches into Health Information Exchanges and pulls hospital records, seven years of prescription history, ER visits, specialist consultations, and mental health treatment records. The days of "forgetting" to mention a prior condition are effectively over.

Hearing examination

Your hearing test happens in a soundproofed booth: calibrated headphones and pure tones across six frequencies (500, 1000, 2000, 3000, 4000, and 6000 Hz, though no pass/fail standard applies at 6000). Press the button every time you hear a tone, however faint.

The disqualifying thresholds per DoDI 6130.03 (1):

• At 500, 1000, and 2000 Hz: no single ear over 30 dB, and the three-frequency average can't exceed 25 dB
• At 3000 Hz: no more than 35 dB
• At 4000 Hz: no more than 45 dB
• Asymmetric loss of 30 dB or more between ears at any frequency from 500 to 2000 Hz is also disqualifying

Results feed your PULHES profile (the "H" is hearing). H1 qualifies you for anything, including noise-sensitive jobs like Air Traffic Control; H2 covers most career fields; H3 and H4 limit or disqualify.

The common ways people fail: noise-induced loss from concerts, headphones, or machinery; tinnitus masking the tones; temporary threshold shift from recent loud noise; earwax; active ear infections. About 15% of applicants show meaningful differences between their MEPS screening and baseline audiograms (5). If you're worried about your hearing, avoid loud environments for 48 hours before your appointment.

Vision testing

Vision screening uses a machine (typically the OPTEC 900), not the wall chart you know. Glasses and contacts are allowed. You're tested with and without, and your corrected vision must meet the standards.

Acuity: distance vision correctable to at least 20/40 in each eye, near vision correctable to 20/40 in the better eye. Refractive error can't exceed plus or minus 8.00 diopters spherical equivalent; astigmatism can't exceed 3.00 diopters (1). Pilot candidates face far stricter numbers: 20/70 uncorrected correctable to 20/20 distance, 20/30 uncorrected near, plus normal color vision and depth perception.

Color vision: starts with the Pseudoisochromatic Plates, the colored-dot patterns with hidden numbers. The Air Force requires 10 of 14 plates (Army and Navy: 12 of 14). Fail that and you can take the Farnsworth Lantern Test (FALANT), distinguishing red, green, and white lights. About 30% of color-deficient people pass it (5). Failing color vision doesn't end your enlistment; it narrows which career fields you can enter. Plenty of AFSCs don't require normal color vision.

Depth perception: the Armed Forces Vision Tester shows rows of five circles where one "pops out" in 3D; you need sections A through D. Alternatives (Verhoeff, Randot, Titmus Fly) exist if the primary test trips you up. Required for pilot training, not for most other jobs. A practical tip: slight side-to-side head movement and a relaxed gaze work better than staring intensely at the circles. Tension kills the depth effect.

Vision maps to the "E" factor in PULHES: E-1 highest, E-2 through E-4 progressively more limited.

Height, weight, and body composition

Measurements round to the nearest whole number (60.9" becomes 61"; 99.6 lbs becomes 100). Air Force height range: 58 to 80 inches (4'10" to 6'8"), pilots 64 to 77 (1). Weight standards have been identical for males and females since 2004. A sample:

Exceed the max and MEPS tapes your body fat: neck and abdomen for males, plus hips for females. Three measurements, averaged, rounded to the nearest half-inch. The Air Force also applies a waist-to-height ratio threshold of 0.55 (waist under 55% of height).

Maximum body fat for accession (April 2023 standards): males under 30, 26%; females under 30, 36%. Both are more generous than the previous 20% and 28% limits (6). Exceeding body fat is a disqualification with no exceptions: lose the weight and return for re-measurement.

Blood draw and urinalysis

The blood panel covers HIV (federally mandated), complete blood count, blood typing and Rh factor, hemoglobin/hematocrit, syphilis (RPR), sickle cell trait, and a comprehensive metabolic panel (glucose, electrolytes, liver and kidney function).

Drug testing uses a 26-drug panel (7): THC, cocaine, amphetamines, methamphetamine, MDMA, heroin and other opioids including fentanyl (added 2019), synthetic cannabinoids, benzodiazepines, PCP, barbiturates, LSD, and more. Collection happens under direct observation by a same-sex MEPS employee. There is no way around this. Positives from the initial screen are confirmed by GC/MS before any action.

If you test positive: a first marijuana positive may allow retesting after 90 days (varies by branch); a first positive for other drugs typically means a one-year wait or permanent disqualification; a second positive for anything is permanently disqualifying. A positive alcohol test means a 45-day wait, retest on day 46.

Pregnancy testing is mandatory for all female applicants before anything else proceeds. Pregnancy is disqualifying (you can't ship to basic while pregnant), with reapplication open after the pregnancy concludes. STI testing covers HIV (positive = disqualifying) plus syphilis and possibly chlamydia/gonorrhea; treatable infections mean a temporary disqualification until treatment is verified. Sickle cell: the disease is non-waiverable; the trait does not prevent enlistment (about 2% of recruits carry it) and comes with counseling about exertional-collapse risk.

Medical history review and MHS Genesis

The paperwork centers on DD Form 2807-2, the Accessions Medical Prescreen Report (updated February 2025): your complete medical history plus the authorization for DoD to request your records (8).

How fast you clear depends on your record. Fifteen or fewer medical encounters may clear within 48 hours; sixteen or more typically takes about 10 days of staff review. As of 2024, 80% of applicants clear to proceed within 48 hours, and the rest average under 7 days, down from a previous 29-day average (9).

The interview covers neurological history, cardiac issues, asthma, mental health (depression, anxiety, ADHD, psychiatric treatment), musculoskeletal history, medications, hospitalizations, and post-age-14 IEP/504 accommodations. You'll certify your answers are "true and complete." False statements violate 18 U.S.C. § 1001 and can mean court-martial or prosecution. With Genesis pulling records regardless, an omission almost certainly surfaces, and a condition discovered is treated far more seriously than a condition disclosed. If something you forgot does come up, explain it and provide context immediately; the worst move is doubling down on the omission. At the end, staff re-ask many of the same questions rephrased. That closing review isn't a trap; it's designed to jog genuinely forgotten memories.

Conditions Unlikely to be Waived (CUW)

Effective May 4, 2026, USMEPCOM's "Conditions Unlikely to be Waived" prescreen policy stops processing up front for applicants who disclose any of 28 specific conditions the services agree are unlikely to be waived (17): diabetes (Type I or II), sickle cell disease, certain food allergies such as peanut, narcolepsy, heart valve replacement, Crohn's disease, bipolar disorder, and a history of two or more suicide attempts, among others. Flag one of these and you won't be scheduled for the exam until the condition is reviewed with additional Service sign-off. The intent is to spare you a full exam that ends in an unwinnable waiver wait; in practice, a listed condition now pauses processing earlier than it used to.

The physical examination

The Chief Medical Officer (or designated medical officer) makes the final qualification call. The typical sequence: check-in with biometrics, orientation, urinalysis, blood draw, vision, hearing, height/weight/vitals, history interview, head-to-toe physical, orthopedic and neurological screening, and specialty consultations if needed. Screening stations are staffed by military medical technicians; the hands-on exam is provider-conducted.

For males: visual inspection of external genitalia and a hernia check (the "turn your head and cough" maneuver, both sides), plus inspection for hemorrhoids and fissures. For females: pregnancy test first, a breast examination, gynecological history review, and possibly a pelvic exam depending on reported issues.

Privacy is regulated, not discretionary (USMEPCOM Reg 40-1, Ch. 3-6): sensitive exams happen in private rooms with gowns or drapes, only essential staff present, every procedure explained first, a female attendant present for female applicants, and same-sex examiners for all sensitive procedures (10).

What to wear: males, boxers, boxer-briefs, or briefs; females, standard bra and underwear (sports bras and thongs aren't authorized). No military uniforms unless you're already serving.

Orthopedic and neurological screening

The orthopedic screening was simplified in January 2022, from 23 group maneuvers (the old "underwear Olympics") down to 10, evaluated individually (5).

The duck walk is the one everybody asks about, because it tests several systems at once: hip, knee, and ankle flexibility, balance, leg strength, flat feet, and nervous system function. The current version is just 2 to 3 steps, not the across-the-room march of older years. Doing it right: drop into a low partial squat, knees bent outward, walk forward staying low, feet rolling heel-to-toe without standing up. Practice squats, lunges, and the duck walk itself before your appointment. This is where physically healthy people get tripped up simply because they never rehearsed the movement.

Range of motion minimums (below these is disqualifying) (1):

Common orthopedic disqualifiers: scoliosis over 30 degrees, three or more surgeries on the same knee, ACL reconstruction within 12 months or still symptomatic, any surgical spinal fusion, hip arthroscopy, joint replacement. Retained hardware (plates, pins, screws) is not disqualifying if healed, stable, and pain-free. Flat feet are judged by function, not appearance: "rigid or symptomatic" is disqualifying; flexible and asymptomatic is not. Red flags are pain during activity, plantar fasciitis or stress fracture history, and inability to wear standard boots (1).

Neurological screening checks balance, coordination, motor strength, sensation, and reflexes. Disqualifying: seizures after your 6th birthday (unless seizure-free and off medication for 60 months), moderate-to-severe brain injury, multiple mild brain injuries, and migraines needing prescription medication more than twice in 12 months.

Behavioral health screening

USMEPCOM moved to person-to-person behavioral health interviews in 2011 (conversations produce more honest disclosure than forms), and since December 2023 has been adding virtual consultations with clinical psychologists at high-need MEPS (11). For many applicants this is the most anxiety-producing station, especially given how common mental health treatment is among young adults. The details matter here, because the standards are more navigable than they first sound.

The DD Form 2807-2 contains 12 behavioral health questions, 3 alcohol questions, and specifics on ADHD, IEPs/504 plans, psychiatric treatment, depression, suicidal ideation, and sleep. The interview covers five focus areas: law enforcement encounters, school discipline, behavioral health visits, self-harm history, and home environment (8).

ADHD is disqualifying if an IEP/504 or work accommodations were recommended after your 14th birthday, you have comorbid mental disorders, or documentation shows the condition hurt academic or occupational performance. The big change: under the Medical Accession Review Period (MARP), the medication-free requirement dropped from 3 years to 1 year in October 2024 (12). Off ADHD medication for a year? You may qualify without a waiver. That matters at scale: ADHD is roughly 60% of all MARP enlistments (12).

Depression and anxiety are disqualifying if outpatient care (counseling included) exceeded 12 cumulative months, symptoms or treatment occurred within the last 36 months, there was any inpatient treatment, any recurrence, or any suicidality (1). Those standards sound like they'd screen out half of today's applicants, but the reality is more forgiving. Anxiety was among the top three conditions the Air Force approved waivers for in FY2024 (3). A history doesn't mean you can't serve; it usually means you need a waiver, and people with treatment histories successfully enlist all the time. Psychiatric medication within the previous 36 months is disqualifying unless a shorter period applies (1); MARP has shortened several of these timelines.

Suicidality and self-harm are the hard lines: any suicide attempt, gesture, ideation with a plan, or ideation within the previous 12 months is categorically disqualifying, as is endorsed, documented, or scar-evident self-harm. Providers specifically look for cutting or burning scars during the physical. As of July 2025, a suicide attempt within 12 months is on the no-waiver-under-any-circumstances list (13).

If you're disqualified

The outcome depends on which kind of disqualification you get. (Full process: disqualifications and waivers.)

Temporary Disqualification (TDQ) covers conditions that heal: broken bones, infections, acute illness. No waiver needed; prove it resolved and come back. Timelines run from days to months depending on the condition; MEPS tells your recruiter exactly what documentation reopens the door (return visits to MEPS).

Permanent Disqualification (PDQ) covers conditions that won't resolve: prior surgeries, chronic conditions, certain diagnoses. The name misleads: PDQ does not mean you can never serve. It means MEPS needs more information, and PDQ status is actually required before a waiver application can even begin.

The Air Force waiver process runs through AETC's medical waiver authority at JBSA-Randolph, evaluating whether you can safely serve a full enlistment including at least one deployment (3). Know the odds going in: the Air Force approves the lowest share of waivers of any service, about 65% (Marines about 98%, Navy and Army near 77%), and averages 95 days to process. Simple cases resolve in a week or two; complex ones stretch to months (14). Your package needs complete medical records, specialist letters on letterhead with current status, treatment records, and diagnostics. MEPS-ordered consultations are government-paid; private specialist evaluations for your waiver package are on you.

MARP deserves its own mention: launched June 2022 as a DoD pilot with 38 conditions, now covering 51 disqualifying conditions with reduced waiting periods. Between July 2022 and August 2024 it medically qualified over 9,900 applicants, and 57% successfully enlisted (12). The FY2025 NDAA (Section 535) requires a year's notice to Congress before the program can be terminated (15).

The July 2025 tightening: a SecDef memo created two new restriction tiers: 13 conditions now requiring Service-Secretary-level approval for any waiver (corneal transplant, implanted pacemaker, dialysis-dependent kidney disease, psychotic-feature disorders), and 13 fully waiver-ineligible (cystic fibrosis, ALS, MS, current epilepsy, current schizophrenia treatment) (13). Practical impact on typical applicants is limited, since none of these overlap the common waiver categories (ADHD, astigmatism, childhood asthma, allergies). But the direction is clear: after years of loosening, standards are tightening.

Preparing for the exam

The medical exam typically takes one to two days, with food and lodging provided. It is, per MEPS's own staff, more like a long day at the doctor's office than boot camp. Nobody yells, and the staff see nervous applicants every single day. (The 67 locations do vary in wait times and flow; the standards are identical everywhere.)

Bring: REAL ID-compliant photo ID (required since May 7, 2025) (16), your original Social Security card, birth certificate, medical records and doctor's notes for anything disclosed, glasses or contacts with your current prescription, and education documents.

In the days before: practice squats, lunges, and the duck walk; stretch hamstrings and hip flexors; protect your ears from loud environments for 48 hours.

Day of: sleep well, hydrate, and skip the caffeine. It raises blood pressure and heart rate, and a high reading delays processing. Nerves do the same, and staff will give you a chance to rest and re-check. Wear the right underwear. Bring a book, because there's real downtime between stations.

And the preparation that outranks all of it: total transparency about your medical history. Genesis will surface it anyway. Disclosed early, a condition is a waiver conversation; discovered late, it's a credibility problem.
