Search “medical sales” on a general job board and you will mostly see primary care pharma, mixed specialty postings, and occasional device territory roles. Biotech and diagnostics selling—IVD immunoassays, molecular diagnostics, hospital lab automation, pathology workflows, and life-science reagents—sits in a different lane. The buyers, call points, evidence, and comp models diverge from both OR-based device work and Rx detailing. If you are exploring a move or hiring your first diagnostics rep, treating all three as interchangeable leads to mismatched interviews, noisy applicant pools, and slow ramp.
Three lanes, three different selling environments
- Medical device (ortho, spine, cardio, capital, etc.): procedural workflow, surgeons and ASC/hospital committees, OR and cath lab credibility
- Pharmaceutical / primary care: physician detailing, access and payer dynamics, Rx-focused messaging within label
- Biotech & diagnostics: lab directors, pathologists, core lab managers, hospital lab networks, molecular and IVD validation, LIS connectivity
Diagnostics reps often win on lab operations fluency—throughput, QC, menu expansion, connectivity—not surgeon lunch relationships alone. Biotech reagent and research instrument roles may skew toward academic medical centers and biotech clusters. None of that shows up clearly when a posting only says “medical sales representative.”
What diagnostics and biotech reps actually sell
- IVD / immunoassay platforms and reagent contracts on core lab menus
- Molecular diagnostics, PCR, and NGS account growth in oncology and infectious disease
- Hospital lab automation, track systems, and pre-analytical workflow
- Anatomic pathology, digital pathology, and specialty staining workflows
- Point-of-care connectivity and lab IT integrations (LIS, middleware)
- Life-science tools: flow cytometry, cell culture, protein analysis, research reagents
Compensation still blends base and variable pay, but quota math may tie to reagent pull-through, installed base retention, or capital-plus-consumable bundles—not implant procedure volume. Employers hiring in this lane should say so explicitly in the job description; candidates should name their lab or research environment in profiles and summaries.
Why generic job boards blur the lanes
- Keyword search returns “medical sales” posts across pharma, device, and diagnostics with no lane filter
- Diagnostics titles hide under “clinical specialist,” “account manager,” or “specialty rep” without IVD context
- Device hiring managers receive pharma applicants; diagnostics managers receive device reps with no lab experience
- Hospital lab roles may post on health-system career sites—not the boards reps search first
Candidate playbook: pick your lane before you apply
- Decide whether you want lab/IVD, molecular, hospital systems, pathology, or research biotech—not “any medical sales”
- Use specialty filters and alerts; search titles like IVD, molecular diagnostics, lab automation, and core lab
- Network with lab directors, pathologists, and lab service managers—not only physician offices
- Prepare stories about menu wins, validation support, connectivity, and lab throughput—not only OR cases
- Read each post for call points: health system lab network vs independent lab vs reference lab vs academia
Employer playbook: write and source for the lane you need
- Title the role with lane signal: IVD, molecular, core lab, pathology, or lab automation—not generic “medical sales”
- List required lab fluency: LIS, QC, validation, connectivity, or capital-plus-reagent experience as applicable
- Use structured phone screens that separate lab-ready reps from pharma or OR-only backgrounds
- Post on specialty platforms that filter biotech/diagnostics separately from device and pharma noise
