How To Make A Lab

Setting up a laboratory requires coordinating physical space design, safety infrastructure, regulatory certification, and equipment purchasing, often simultaneously. Whether you’re building a clinical diagnostic lab, a research facility, or a small testing operation, the core steps are the same: design a space that controls contamination, outfit it with the right surfaces and safety systems, stock essential equipment, and secure the certifications that let you legally operate. A modest startup lab can cost anywhere from $50,000 to well over $500,000 depending on scope, with individual pieces of equipment ranging from a few hundred dollars to tens of thousands.

Plan Your Lab Layout Around Workflow

The single most important design principle is one-way flow. Specimens, people, and waste should each move through the lab on separate, non-overlapping paths. This prevents cross-contamination and keeps operations efficient. Think of your space as a series of zones arranged from cleanest to most contaminated, with materials progressing in one direction only.

A well-designed lab typically has four zones:

  • Clean zone: offices, data storage, meeting areas
  • Buffer/preparation zone: specimen receiving, registration, and pre-processing
  • Core laboratory zone: where active testing, processing, and analysis happen
  • Waste staging area: a separate space for medical and chemical waste before disposal

Specimens should enter through dedicated pass-through windows or transfer routes into the receiving area, then move forward into the core lab. Staff enter through separate changing or buffer rooms, and backward movement from a contaminated zone into a clean zone is not allowed. Reagents, consumables, and clean supplies enter through their own access points, completely separated from specimen paths. Waste leaves through dedicated routes or on staggered schedules, never mixing with clean materials.

Choose the Right Surfaces and Furniture

Every surface in a lab needs to withstand chemical exposure, frequent decontamination, and daily wear. Carpets and rugs are prohibited. Chairs, stools, and other furniture must be non-porous and easy to wipe down. Countertops are the biggest material decision you’ll make.

Epoxy resin is the gold standard for labs that handle harsh chemicals. It cures into a solid, non-porous surface that resists moisture, bacteria, and heat up to 350°F (177°C). It won’t corrode, crack, or stain under regular chemical exposure. Phenolic resin, made by layering paper or fabric under heat and pressure, is lighter and more affordable. It holds up well in labs with moderate chemical use but doesn’t tolerate heat as well as epoxy and wears down faster in high-traffic environments. For a chemistry-heavy lab, epoxy is worth the higher cost. For general testing with lighter chemical demands, phenolic resin can save money without major trade-offs.

Install Ventilation and Pressure Controls

Airflow engineering is how labs prevent contaminated air from reaching clean spaces. The CDC recommends a minimum of 6 air changes per hour for both general and microbiology laboratories. That means the entire volume of air in the room is replaced at least six times every hour.

Beyond air exchange rate, you need a pressure gradient that decreases as you move from clean areas toward contaminated ones. Offices and administrative spaces sit at neutral or slight positive pressure, which keeps contaminated air from drifting in. Buffer and preparation areas run at slight negative pressure. The core lab, especially any area where specimens are opened or processed, should be maintained at stable negative pressure (typically negative 5 to negative 10 pascals), ensuring air always flows inward from cleaner spaces. The grossing or specimen-handling room should be the lowest-pressure point in the entire facility.

Set Up Safety and Emergency Equipment

If your lab handles biological agents, you’ll likely need to meet Biosafety Level 2 (BSL-2) standards at minimum. BSL-2 requires restricted access when biological work is in progress, which can mean locked doors depending on the risk level. A biosafety sign must be posted at every entrance listing the agents in use, the biosafety level, the investigator’s name and phone number, a secondary contact, entry requirements, and required protective equipment.

Any procedure that could create infectious aerosols or splashes requires a certified Class II biological safety cabinet, inspected and recertified annually. Work surfaces must be decontaminated with appropriate disinfectants at the end of every workday and immediately after any spill of viable material.

Emergency eyewash stations and deluge showers are non-negotiable in any lab using chemicals or biological agents. These must be positioned so an injured person can reach them within 10 seconds of travel. They need to supply potable water at specified flow rates, and water temperature should be tepid to avoid shocking someone already dealing with a chemical burn or splash injury.

Budget for Essential Equipment

Equipment costs vary enormously by lab type, but here are realistic price ranges for a startup operation:

  • Hematology analyzer: $9,000 to $20,000
  • Electrophoresis equipment: $4,000 to $10,000
  • Laboratory freezer and refrigerator: $5,000 to $15,000
  • Waiting area and blood draw room furniture: $5,000 to $10,000
  • Microscopes: $800 to $3,000
  • Tabletop centrifuge: $300 to $900
  • Pipettes: $100 to $300
  • Initial chemical supplies (growth media, buffers, agar broths): $1,000 to $2,000
  • Consumable supplies (needles, syringes, gloves, gauze): $1,000 to $2,000
  • Computer, printer, and internet setup: $1,000 to $2,000

On top of equipment, factor in software. At minimum, you’ll need a laboratory information management system (LIMS), billing software, and basic office applications. A LIMS tracks samples and associated data through your entire workflow. Good systems also automate workflows, integrate directly with instruments, monitor quality control data, track reagent inventory and lot numbers, and support compliance documentation. For a clinical lab, insurance billing software is essential from day one.

Get Your CLIA Certification

In the United States, any facility that examines human specimens for diagnosis, prevention, or treatment must hold a CLIA certificate issued through the Centers for Medicare and Medicaid Services. The process has five steps:

First, complete the CLIA application (Form CMS-116), available online as a fillable PDF. Check with your state agency for any additional state-specific requirements before submitting. Second, send the completed application and supporting documents to the state agency where your lab is physically located. Third, you’ll receive a fee coupon that includes your unique 10-character CLIA identification number. Use this number for all future communication, tracking, and payment. Pay the certification fee through pay.gov using a bank account, debit, or credit card. Fourth, after payment is received, your CLIA certificate arrives by email and you can begin testing. Fifth, maintain your certification by paying renewal fees every two years, since all CLIA certificate types expire on a two-year cycle.

Some states layer additional licensing on top of CLIA. Always confirm state-level requirements before you begin testing.

Consider Accreditation Beyond CLIA

CLIA certification is the legal minimum for clinical labs, but many labs pursue ISO/IEC 17025 accreditation as well, particularly testing and calibration laboratories. ISO 17025 is an international standard that demonstrates technical competence, and it’s often required by clients, government contracts, or industry partners. The accreditation process involves extensive documentation, proficiency testing, and an assessment by an accrediting body like the ANSI National Accreditation Board. Separate accreditation requirements exist for forensic, calibration, sampling, and dimensional measurement labs, so confirm which standard applies to your specific operation before starting the application.

Handle Hazardous Waste Correctly

EPA regulations govern how labs store, label, and dispose of hazardous waste. If you’re operating under the satellite accumulation area (SAA) rules, each lab space functions as its own collection point. You cannot transfer or consolidate hazardous waste between satellite accumulation areas, meaning you can’t carry waste from one lab into another lab’s collection container.

Working containers (the ones you’re actively adding waste to during a procedure) don’t need full labeling until the end of the procedure or work shift, or until the container is full, whichever comes first. At that point, the container must be closed and labeled. The label needs a term indicating the material is no longer wanted, such as “chemical waste,” “laboratory waste,” or “unwanted material,” used consistently across all your labs and documented in your Laboratory Management Plan. It also needs enough information for an emergency responder to identify the contents: chemical names or descriptive terms like “flammable,” “spent acid,” “halogenated organic solvents,” or “water reactives.” Vague labels like “spent” or “aqueous” don’t meet the standard. You don’t need to include the hazardous waste code on the label while waste is still accumulating in the lab, but you do need sufficient information on or associated with the container to make a hazardous waste determination, along with the accumulation start date.

Designate a clearly separated waste staging area within your facility. Sharps, pathological waste, and chemical waste each require dedicated containers and transport routes that never overlap with clean material paths.
