LIS vs LIMS: What's the Difference and Which Does Your Lab Need?

Laboratory Information Systems (LIS) and Laboratory Information Management Systems (LIMS) both deal with lab data, and some companies use the terms like they're interchangeable...but they're not the same thing.

It is pretty important to understand the difference between the two, especially when you're choosing a system for your lab...otherwise, if you get it wrong before setting up your system, it can lead to compliance issues and expensive replacements down the line.

What is a LIS?

A Laboratory Information System (LIS) is software built specifically for clinical and diagnostic laboratories. Its focus is on managing patient data: collecting test orders, tracking patient samples, recording final test results, and reporting findings to physicians and other healthcare providers. 

LIS software is built with the patient in mind, focusing on their individual record. Each order in the system is tied to a specific patient, creating a clear chain of reporting that goes from the lab to the clinician and finally to the patient. To make this work seamlessly, LIS platforms are designed to integrate with electronic health records, or EHRs, and hospital information systems. They use standardized protocols such as HL7, the common language for sharing data in healthcare settings. This integration is crucial for ensuring that patient information is accurate, up-to-date, and easily accessible to those who need it. By connecting the dots between different systems, LIS software helps healthcare providers make informed decisions and provide better care for their patients.

The regulatory framework for a LIS is built around clinical compliance:

• HIPAA (US): governs the handling of protected health information, including patient test results
• CLIA (US): federal standards for clinical laboratory testing on human specimens
• CAP accreditation: College of American Pathologists laboratory accreditation
• ISO 15189: International standard for quality and competence in medical and clinical laboratories

LIS is designed for use in hospital pathology labs, clinical reference laboratories, point-of-care testing facilities, and any laboratory where the output is a diagnostic result tied to an individual patient. 

What is a LIMS?

A Laboratory Information Management System (LIMS) is software built for laboratories where the work is organized around samples and testing processes. LIMS manages the full operational workflow of the lab: sample receipt and tracking, sample preparation, test scheduling, instrument data capture, results entry and review, QC management, compliance documentation, and reporting. 

A modern LIMS is sample-centric but understands the context of the sample according to the testing scenario.  A sample that is being managed by a LIMS can be associated with many things: a batch of pharmaceutical product, a river water sampling point, a food ingredient, a toxic spill site, a research compound, or a patient.  Results can be reported to QA departments, regulatory submissions, researchers, or clinicians. 

Traditionally, the regulatory framework for a LIMS was built around industrial and research compliance: 

• FDA 21 CFR Part 11: electronic records and signatures requirements for regulated industries in the United States
• EU Annex 11: the European equivalent for computerized systems in pharmaceutical manufacturing
• ISO/IEC 17025: competence requirements for testing and calibration laboratories
• GMP (Good Manufacturing Practice): manufacturing standards for pharmaceutical, food, and device industries
• GLP (Good Laboratory Practice): standards for non-clinical laboratory studies

Traditionally, LIMS were typically used across pharmaceutical, biopharma, food and beverage, environmental testing, petrochemical, forensics, mining and metals, and contract services laboratories. However, increasingly, modern LIMS that have been made compliant with the clinical regulatory framework are being deployed in clinical diagnostic settings.  By virtue of the diverse nature of the industries served, modern LIMS systems have evolved to provide great flexibility in managing different workflows across the laboratory types they support.  

LIS vs LIMS: Key Differences at a Glance

Where LIS and LIMS Overlap

Things were more straightforward twenty years ago, but now the lines are blurred. Laboratory work has evolved, and some environments don't fit perfectly into one category or the other, making it harder to distinguish between them.

Clinical Diagnostic labs use either a LIS or a LIMS that is capable of meeting the demands of a clinical diagnostic lab.  

Veterinary diagnostic labs process animal specimens, often connecting to farm or practice management systems. Depending on the setting, either a LIS or a LIMS may be appropriate.

Large hospital systems frequently run both: a clinical LIS in the pathology and diagnostics division, and a LIMS in any in-house pharmaceutical manufacturing, research, or environmental monitoring operation. These are separate deployments serving separate functions.

Which One Does Your Lab Need?

Three questions narrow this down:

1. Are your samples linked to only individual patients, and do results go directly to clinicians or electronic health records? If yes: you can use an LIS or a LIMS that supports diagnostic testing.  

2. Are some or all of your samples linked to production lots, research studies, or environmental monitoring programs? Do some or all of your results go to QA, regulatory submissions, or internal research teams?  If yes: you may need a LIMS.

3. Do you require that your staff be empowered to configure new and existing lab workflows as your requirements change due to shifting customer needs, technological evolution, and changing regulatory requirements? If yes: you may need a LIMS. 

A Note on Terminology

There is no universally enforced definition of LIS vs LIMS. Some vendors use the terms interchangeably. Some clinical systems are marketed as LIMS. Some LIMS are used in settings traditionally associated with LIS. 

What really counts is what a system is actually designed to do, not what it is called. For example, a system that is meant to manage patient data and work with HL7 will not be useful in a lab that tests pharmaceuticals, no matter what the company selling it says. On the other hand, a system that is built only for testing production lots, working with instruments, and following strict rules like 21 CFR Part 11 is not a good fit for a lab that does clinical diagnostics. It is all about finding the right tool for the job. A system that is perfect for one lab might not work at all in another.  So, it is really important to understand what a system can do and whether it is a good match for your specific needs. 

When evaluating systems, ask vendors about the regulatory frameworks they were built to support and the industries where they have active deployments. The product name tells you less than you would expect.
