Add Molecular Testing to Your Lab: Costs and Financing
Many clinical and pathology labs want to add molecular testing so they can offer infectious disease panels, oncology markers, pharmacogenomics or other genomic tests in-house instead of sending them out. A molecular department can expand the services a lab offers its clients, but it is also one of the most capital-intensive expansions a lab can undertake.
This article outlines the main costs, the reimbursement and operational questions to answer first and how the expansion may be financed. Coverage, validation and regulatory requirements vary, and nothing here is legal, regulatory, billing or compliance advice.
Why Labs Add Molecular Testing
Labs pursue molecular capabilities for several reasons:
- Keeping send-out tests in-house to improve turnaround for clients
- Responding to client demand for infectious disease, women’s health or oncology panels
- Supporting anatomic pathology with molecular markers on tissue specimens
- Diversifying revenue beyond routine chemistry and hematology
- Positioning the lab for future genomic and precision medicine testing
The decision should start with a clear view of which tests clients will order, at what volume and whether payers will cover them.
Planning Before You Add Molecular Testing
Before committing capital, labs should answer several questions:
- Menu: which tests will you offer first, and will they use cleared kits or laboratory-developed tests?
- Volume: how many specimens do clients send out today, and how many would come in-house?
- Coverage: do Medicare, Medicaid and the lab’s commercial payers cover these tests, and with what documentation requirements?
- Staffing: do you have, or can you recruit, technologists and a director with molecular experience?
- Certification: does the expansion change your certificate specialties or state licensure?
Coverage questions are especially important. Molecular tests can face prior authorization, medical necessity reviews and higher denial rates, and qualified billing or compliance professionals should review the plan.
Equipment and Technology Costs
Depending on the menu, a molecular department may require:
- Nucleic acid extraction instruments
- Real-time PCR systems
- Liquid handlers and automation
- Sequencing platforms and bioinformatics capacity for genomic tests
- Biosafety cabinets, centrifuges, freezers and refrigerators
- Interfaces with the laboratory information system and client ordering systems
Reagents and controls used during validation, along with service contracts and training, should also be budgeted. Our guide to laboratory equipment financing discusses loans, leases and reagent rental options for analyzers, PCR and sequencers.
Space and Workflow Requirements
Molecular testing generally requires a unidirectional workflow, with physically separated areas for reagent preparation, specimen preparation and amplification to reduce contamination risk. Many labs need dedicated rooms, additional ventilation, sinks and electrical capacity.
If your current space cannot accommodate that workflow, renovation or expansion may become a large part of the budget. Our article on clinical lab build-out cost explains the space, HVAC and safety items that drive construction.
Staffing and Validation
Molecular testing demands experienced personnel. A lab may need molecular technologists, a supervisor with molecular expertise and, for certain tests, additional director qualifications. Recruiting can take time, and salaries for specialized staff often begin before tests are billable.
Every test must be verified or validated before clinical use. For laboratory-developed tests, validation can be extensive. During this period, the lab carries staff, reagent and equipment costs without corresponding revenue.
Ramp-Up and Working Capital
New molecular tests often take time to reach expected volume. Clients need education, ordering systems need updates and payers may take time to pay consistently. Building working capital into the expansion plan can help the lab manage the ramp-up period without straining existing operations.
Financing the Expansion
Labs that add molecular testing often combine several financing tools:
- Equipment financing: for instruments, with terms matched to useful life; see our lab equipment financing and leasing page
- Expansion loans: for build-out, equipment and working capital in a single facility
- SBA 7(a) loans: SBA 7(a) financing may be used for expansion projects, including equipment, improvements and working capital; eligibility and terms depend on the business, the borrower, use of proceeds, program rules and lender review
Lenders generally review the lab’s existing cash flow, the business case for the new tests, client commitments, coverage analysis, staffing plan and the owners’ credit. Every loan is subject to approval. You can estimate payments with our SBA loan calculator; estimates are for planning purposes only and do not represent an offer or approval.
Phasing the Expansion
Not every lab needs to launch a full molecular menu at once. Some begin with a small set of high-demand tests on a single platform, then add panels, automation or sequencing as volume and payer experience grow. Phasing can reduce the up-front commitment, give staff time to build expertise and allow the lab to test its assumptions before investing further.
Building the Business Case
A strong expansion plan typically includes current send-out volume by test, expected in-house volume, payer coverage by test, a cost-per-test estimate, a staffing plan, a validation timeline and conservative revenue projections. Presenting this information clearly can make the request easier for a lender to evaluate.
Final Thoughts
The decision to add molecular testing can expand a lab’s services and client value, but it requires careful planning around coverage, staffing, space, validation and cash flow during ramp-up. Financing the expansion as a complete project, rather than one instrument at a time, can help keep the lab on stable footing.
