An in-house veterinary laboratory allows a clinic to perform blood, urine, fecal, cytology, and other routine diagnostic tests quickly. The room must support accurate testing while reducing contamination and occupational hazards.
Recommended Laboratory Size
The required area depends on testing volume and equipment.
Practical planning ranges include:
- 6–8 m², or 65–86 sq. ft., for a compact basic laboratory
- 8–12 m², or 86–129 sq. ft., for a standard small-animal clinic laboratory
- 12–18 m², or 129–194 sq. ft., for a busier clinic with several analyzers and multiple workstations
A narrow room should still provide at least 1.2 meters, or about 4 feet, of clear circulation space where staff work behind one another.
Laboratory Zoning
The laboratory should be divided into functional zones:
- Sample reception and labeling
- Sample preparation
- Analyzer and microscope work
- Refrigerated storage
- Cleaning and decontamination
- Waste disposal
- Clean-supply storage
Clean materials should not be stored beside used samples, contaminated instruments, or waste containers.
Worktop Dimensions
Laboratory counters are commonly planned at approximately:
- 85–95 centimeters high
- 60–75 centimeters deep
At least one seated work area may be useful for microscopy and data entry.
Worktops should provide adequate space around analyzers for ventilation, maintenance, and safe cable management.
Recommended Materials
Laboratory work surfaces should be:
- Non-porous
- Chemical-resistant
- Moisture-resistant
- Heat-resistant where required
- Smooth and easy to disinfect
- Free from damaged joints or absorbent edges
Suitable materials include epoxy resin, compact-grade laminate, stainless steel, or approved solid-surface products.
Wooden household counters, porous stone, and damaged laminate should be avoided.
Flooring and Walls
Laboratory flooring should be seamless or have sealed joints. Suitable materials include sheet vinyl, resin, or commercial safety flooring.
Walls should have washable coatings. Splash-prone areas behind sinks and sample-processing zones may use hygienic wall panels or sealed backsplashes.
Essential Laboratory Equipment
A general clinic laboratory may include:
- Microscope
- Centrifuge
- Hematology analyzer
- Blood chemistry analyzer
- Urine analyzer
- Refractometer
- Sample refrigerator
- Small freezer, if required
- Pipettes and sample racks
- Computer workstation
- Label printer
- Handwashing sink
- Eyewash equipment, where required
- Biohazard and sharps containers
Food, drinks, and personal items should never be stored in a laboratory refrigerator.
Sink and Handwashing Area
The laboratory should have a sink for handwashing or specimen-related cleaning, depending on local standards and workflow.
Soap, disposable towels, gloves, and appropriate disinfectants should be accessible.
The sink should not be surrounded by electrical analyzers that could be damaged by splashing.
Electrical and Data Requirements
Laboratory analyzers often require dedicated electrical outlets, network connections, surge protection, and stable environmental conditions.
Extension cables should not cross working areas. Power outlets should be installed above counter height or in protected locations.
Ventilation and Temperature
The room should maintain a stable temperature appropriate for laboratory equipment and reagents.
Ventilation should remove excess heat, odors, moisture, and chemical fumes. Equipment should not be positioned against walls if manufacturer instructions require airflow.
Sample and Waste Management
Every sample should be labeled immediately with patient identification, collection date, and sample type.
Sharps containers should be positioned close to sample-collection and processing areas. Biohazardous materials, chemical waste, broken slides, and general waste should be separated according to local requirements.
