Molecular Diagnostics and PCR Lab Casework in Utah
PCR labs need a one-way workflow and surfaces that survive daily bleach. Labs USA plans laboratory casework zone by zone for Utah clinical, public health, research and diagnostics labs.

Why PCR Labs Need Their Own Layout
PCR can copy a single strand of DNA or RNA billions of times, and that strength is also its weak spot. A trace of amplified product on a counter, a pipette or a drawer handle can end up in the next sample and cause a false positive. That is why a molecular lab has to be laid out differently from a general chemistry or teaching lab.
For clinical labs this is a regulation, not just good practice. Under CLIA, molecular amplification that is not done in a closed system must follow a one-way workflow, with separate areas for specimen preparation, amplification and product detection, and for reagent preparation where it applies (42 CFR 493.1101). CMS inspectors check it under tag D3005 (CMS Appendix C). Laboratory casework is how those separate areas become real, working benches.
The Four Zones of a Molecular Lab
The World Health Organization describes the classic layout as four separate rooms, or at least four physically separate areas, with work moving in one direction from clean to dirty (WHO, Dos and don’ts for molecular testing):
Each area keeps its own labeled equipment, supplies, lab coats and gloves at its own workstation, and staff should not walk from post-PCR areas back to clean areas on the same day. Every one of those rules has a furniture answer: dedicated benches, enough storage so nothing has to be borrowed, and a layout that makes the one-way path the easy path. Our laboratory floor plan guide covers the room planning side.
Casework for Each Zone
Reagent prep. This area needs little bench space but a lot of discipline. Plan a short run of base cabinets with drawers for filter tips, tubes and reagent kits, plus wall cabinets so supplies stay closed and clean. Leave counter depth for a PCR workstation. Our PCR hood vs biosafety cabinet guide explains which enclosure fits which step.
Extraction. Sample handling needs more counter length, room for extraction instruments and a biosafety cabinet if specimens call for one, and closed storage for consumables.


Amplification and detection. Thermocyclers and detection instruments are heavy, give off heat and need power. Steel tables or base cabinets with a solid top handle the load, and mobile base cabinets make it easy to clean behind instruments. See lab tables in Utah for table options.
Keep these rooms fully equipped with their own supplies. If staff have to fetch tips or racks from a clean area, the one-way rule breaks down.
Most molecular labs do best with a modular laboratory casework system, so each zone can be sized on its own and moved or added to as test menus grow.
Work Surfaces That Survive Daily Bleach
Molecular work surfaces get wiped down constantly. University of Washington safety guidance calls for fresh 10% bleach daily with at least 10 minutes of contact, followed by water or 70% ethanol to remove the residue, and notes that ethanol alone does not remove nucleic acids (UW EH&S amplicon guidance).
That routine rules out porous or seam-heavy tops. Epoxy resin and phenolic resin are the usual choices in molecular labs. Our epoxy resin vs phenolic countertops guide compares them. Always check the disinfectants you use against the top maker’s chemical resistance chart.

- Seamless or tightly sealed tops with few joints where residue can collect
- Integral or sealed backsplashes so wall edges can be wiped
- Closed wall cabinets instead of open shelves over clean benches
- Drawer and door hardware that holds up to daily wipe-downs
- Color coding or labeling so each zone’s furniture and supplies stay put
Molecular Testing in Utah
Salt Lake City is one of the country’s busiest molecular testing centers. ARUP Laboratories, a nonprofit enterprise of the University of Utah, runs more than 70 labs on a 750,000-square-foot Salt Lake City campus, including molecular and genetic testing (ARUP fact sheet). BioFire Diagnostics, maker of multiplex PCR systems, is registered with the FDA at a Salt Lake City address (FDA establishment record), and the Utah Public Health Laboratory runs real-time PCR assays for infectious disease (UPHL virology).
That ecosystem feeds hospital labs, startups and university research groups across the Wasatch Front, from Ogden to Provo, and into St. George and Logan. Labs USA is a Utah company, so we can visit your site, review your drawings and plan casework for each zone. Public health and forensic labs, see our public health and forensic lab casework in Utah guide.
Planning Your Molecular Lab Casework
A good casework quote for a molecular lab starts with the workflow, not the furniture. Bring these details:
- Your test methods, and whether any run in closed systems that change the space needs
- How many separate rooms or areas you have, and which is clean and which is dirty
- Instruments in each area, with approximate sizes, weights and power needs
- The disinfectants and cleaning schedule your quality plan requires
- Whether you need a PCR workstation or biosafety cabinet space on the bench

Frequently Asked Questions
Does CLIA require separate rooms for PCR?
CLIA requires a one-way workflow with separate areas for specimen preparation, amplification and product detection when amplification is not done in a closed system. Separate rooms are the strongest option, and WHO guidance allows physically separate areas where rooms are not possible.
What countertop is best for a PCR lab?
Epoxy resin and phenolic resin are the most common because they are non-porous and stand up to frequent disinfection. Check your cleaning agents against the manufacturer’s chemical resistance data before you choose.
Can one bench serve both pre-PCR and post-PCR work?
It should not. Mixing clean and amplified work on one bench is a common source of contamination. Each area needs its own bench, storage and equipment.
Do molecular labs need a PCR workstation or a biosafety cabinet?
It depends on the step. A PCR workstation protects reagents during master mix prep, while a biosafety cabinet protects staff and samples when handling infectious specimens. Many labs use both.
Is mobile casework a good idea for a molecular lab?
Mobile base cabinets and tables make it easier to clean behind instruments and to rearrange as test menus change. Fixed casework is still best for sinks and heavy instruments.
Do you serve molecular labs outside Salt Lake City?
Yes. Labs USA plans and installs laboratory casework throughout Utah, including Ogden, Provo, Logan and St. George.
