What Is LIS Automation? A Complete Guide for Modern Diagnostic Laboratories

Diagnostic laboratories are under increasing pressure to process more samples, deliver reports faster, reduce manual errors and maintain better control over every stage of testing.

For a small laboratory, managing patients and results manually may initially seem manageable. However, as the number of patients, tests, staff members and diagnostic services increases, manual processes can quickly become difficult to control.

This is where LIS automation becomes important.

A Laboratory Information System, commonly known as an LIS, helps laboratories manage the complete diagnostic workflow digitally. From patient registration and test ordering to result entry, approval and report delivery, an LIS can bring multiple laboratory activities into one organized system.

But what exactly is LIS automation, how does it work, and what should a diagnostic laboratory look for before choosing laboratory management software?

This guide explains everything.

What Is LIS Automation?

LIS automation refers to the use of a Laboratory Information System to digitize, organize and automate laboratory workflows.

Instead of relying on paper registers, spreadsheets and disconnected software, laboratory staff can manage information through a centralized digital system.

A typical automated laboratory workflow may include:

1. Patient registration
2. Test selection
3. Sample collection
4. Sample tracking
5. Result entry
6. Quality review
7. Result approval
8. Report generation
9. Digital report delivery
10. Billing and operational reporting

The level of automation can vary between laboratories.

Some laboratories may primarily use the LIS for patient registration and report generation.

More advanced laboratories may integrate:

1. Laboratory instruments
2. Barcode systems
3. Sample tracking
4. Automated analyzers
5. Inventory systems
6. Patient portals
7. Hospital systems

The main objective remains the same:

Reduce unnecessary manual work and create a more organized, traceable laboratory workflow.

Why Do Diagnostic Laboratories Need Automation?

Laboratories deal with large amounts of structured information every day.

A single patient may have multiple tests.

Each test may contain several parameters.

Each parameter may have different reference ranges based on factors such as:

1. Age
2. Sex
3. Test methodology
4. Clinical category

When hundreds of patients are processed daily, managing this information manually becomes increasingly difficult.

Common problems in manual or disconnected workflows include:

1. Repeated patient data entry
2. Typing errors
3. Missing results
4. Difficulty tracking pending tests
5. Delayed approvals
6. Inconsistent report formats
7. Difficulty monitoring staff activity
8. Limited inventory visibility
9. Slow report delivery

Laboratory automation helps create a structured workflow where each stage is connected to the next.

How Does a Laboratory Information System Work?

Although every laboratory has its own workflow, a modern LIS generally follows a sequence similar to the following.

1. Patient Registration

The laboratory first creates or identifies the patient record.

Important information may include:

1. Patient name
2. Age or date of birth
3. Gender
4. Contact information
5. Patient identification number

Using a centralized patient record can help reduce duplicate registrations.

For returning patients, staff may be able to locate an existing profile rather than entering the same information repeatedly.

2. Test Ordering and Selection

After registration, laboratory staff select the required tests.

A well-structured laboratory system should support:

1. Individual tests
2. Test panels
3. Multiple parameters
4. Different result types
5. Reference ranges

For example, a Complete Blood Count may contain multiple parameters, including:

1. Hemoglobin
2. White blood cells
3. Red blood cells
4. Platelets

Instead of treating the entire panel as a single text field, a structured LIS can organize each parameter separately.

This makes result entry, reporting and future data management easier.

3. Sample Collection and Laboratory Workflow

Once tests are ordered, the laboratory begins the sample-related workflow.

Depending on the laboratory setup, this may include:

1. Sample collection
2. Sample identification
3. Barcode labeling
4. Department assignment
5. Worklist management

At this stage, laboratory automation can help staff identify:

1. Which samples are pending
2. Which tests are in progress
3. Which results require entry
4. Which reports are awaiting approval

A clear workflow is particularly important when multiple departments and staff members are involved.

4. Result Entry

Result entry is one of the most important stages in laboratory operations.

Different tests may require different types of results.

For example:

Numeric results

Examples include:

1. Glucose
2. Hemoglobin
3. Cholesterol

Positive or negative results

Examples include some:

1. Infectious disease tests
2. Screening tests
3. Molecular tests

Text-based results

These may be used for:

1. PCR interpretations
2. Histopathology
3. Microbiology observations

Symbol-based results

Some laboratory workflows may use:

1. 
   
2. ++
3. +++
4. Negative
5. Positive

A flexible Laboratory Information System should support the result structure required by the laboratory rather than forcing every test into the same format.

5. Review and Approval

Result entry and result approval should not necessarily be treated as the same process.

In a well-organized laboratory workflow, different stages may include:

Pending → Entered → Reviewed → Approved

This provides greater control over the reporting process.

For example:

A laboratory technician may enter the result.

A senior technologist or authorized professional may review it.

An authorized approver may then approve the final report.

This type of workflow can improve accountability and help prevent incomplete or unreviewed results from being released.

6. Report Generation

After approval, the system can generate a laboratory report.

A digital report may include:

1. Patient information
2. Test names
3. Result values
4. Units
5. Reference ranges
6. Report date
7. Laboratory information
8. Authorized approval details

Standardized report generation can help laboratories maintain consistency.

Instead of manually formatting each report, the system can generate reports according to a predefined structure.

7. Digital Report Delivery

Patients increasingly expect convenient access to their healthcare information.

A patient portal or online report system can allow patients to access approved reports digitally.

This can help reduce:

1. Repeat visits to collect reports
2. Manual report distribution
3. Administrative workload

It can also create a better patient experience.

The AInfomics ecosystem supports connected patient access, while HealthFlow Pro is designed to manage laboratory workflows from patient registration through approved report delivery.

What Are the Main Benefits of LIS Automation?

The value of an LIS is not simply that it replaces paper.

The real benefit comes from creating a structured and connected workflow.

Reduced Manual Data Entry

When information is stored centrally, staff may not need to repeatedly enter the same patient details into different registers or software systems.

This can reduce unnecessary administrative work.

Better Workflow Visibility

Laboratory staff and managers can identify the status of work.

For example:

1. Pending tests
2. Tests awaiting results
3. Reports awaiting approval
4. Completed reports

This makes it easier to identify delays.

Improved Result Management

Structured result entry can help laboratories maintain consistency across tests and departments.

It also allows laboratories to manage different types of results, including numeric, text-based and qualitative results.

Faster Report Generation

Once results are entered and approved, reports can be generated digitally.

This can reduce the time spent manually creating or formatting reports.

Better Staff Accountability

Role-based workflows can help define who is responsible for specific activities.

For example:

1. Registration staff
2. Laboratory technicians
3. Reviewers
4. Approvers
5. Administrators

This can provide better visibility into laboratory operations.

Improved Patient Experience

Patients benefit when laboratories can provide:

1. Faster reporting
2. More organized records
3. Digital report access
4. Reduced waiting

Technology should not only improve laboratory administration. It should also improve the experience of the person receiving healthcare.

The purpose of automation is not to eliminate laboratory professionals.

Instead, it allows professionals to spend less time managing repetitive administrative processes and more time focusing on laboratory operations and quality.

What Features Should You Look for in Laboratory Management Software?

Not every laboratory needs the same software.

However, there are several important features to evaluate.

1. Patient Management

The system should provide a structured way to:

1. Register patients
2. Search existing patients
3. Manage patient identifiers
4. Access previous laboratory activity

2. Test Catalog Management

A laboratory should be able to organize:

1. Test categories
2. Individual tests
3. Test panels
4. Parameters
5. Units
6. Reference ranges

A flexible catalog becomes increasingly important as the laboratory expands its services.

3. Multiple Result Types

The software should support the types of results used in your laboratory.

This may include:

1. Numeric values
2. Positive/negative
3. Text
4. Symbols
5. Structured interpretations

4. Reference Range Management

Reference ranges may vary based on:

1. Age
2. Gender
3. Patient category
4. Laboratory methodology

The system should provide enough flexibility to manage these differences.

5. Review and Approval Workflows

The system should clearly separate different stages of the reporting process.

For example:

1. Result entered
2. Under review
3. Approved
4. Released

6. Report Generation

Look for software that can generate clear and professional reports.

Consider whether the report can include:

1. Laboratory branding
2. Patient details
3. Reference ranges
4. Authorized signatures or approval information

7. Inventory Management

Laboratories use:

1. Reagents
2. Kits
3. Consumables
4. Other laboratory items

Inventory management can help laboratories monitor stock movement and availability.

8. Outsourcing Management

Some laboratories send specialized tests to external laboratories.

A laboratory system should help track:

1. Outsourced tests
2. External providers
3. Pending outsourced results
4. Completion status

9. User Roles and Permissions

Different staff members should not necessarily have access to every function.

A laboratory may require separate permissions for:

1. Registration
2. Result entry
3. Review
4. Approval
5. Administration

10. Ability to Scale

The software should not become obsolete when the laboratory grows.

Consider future requirements such as:

1. Multiple laboratory branches
2. Higher patient volume
3. More staff
4. More tests
5. Hospital integration
6. Pharmacy integration
7. Online patient access

LIS vs LIMS: Are They the Same?

LIS and LIMS are sometimes used interchangeably, but they can serve different purposes depending on the industry.

LIS: Laboratory Information System

An LIS is commonly associated with clinical and diagnostic laboratories.

It may focus on:

1. Patients
2. Test orders
3. Results
4. Reports
5. Clinical workflows

LIMS: Laboratory Information Management System

A LIMS is often associated with broader laboratory environments, including:

1. Research laboratories
2. Industrial laboratories
3. Pharmaceutical laboratories
4. Environmental testing
5. Scientific research

However, the distinction is not always absolute.

When choosing software, the most important question is not simply whether it is called LIS or LIMS.

The important question is:

Does the system support the actual workflow of your laboratory?

Can a Small Laboratory Benefit From LIS Software?

Yes.

Laboratory software is not only for large organizations.

Even a small laboratory may benefit from:

1. Digital patient records
2. Structured test management
3. Faster report generation
4. Better tracking of pending work
5. Organized result approval

The key is choosing software that matches the scale and requirements of the laboratory.

A small laboratory should not necessarily be forced to purchase an overly complicated enterprise platform with features it will never use.

This is one reason modular healthcare software can be useful.

A laboratory can begin with the functions it needs and expand as operations grow.

How LIS Automation Can Support Laboratory Growth

As a laboratory grows, operational complexity increases.

The laboratory may add:

1. More tests
2. More staff
3. New departments
4. Higher patient volumes
5. Multiple collection centers
6. Specialized diagnostic services

Without structured systems, growth can increase administrative complexity.

An LIS can provide a foundation for managing this expansion.

For example, a laboratory may begin by using software for:

1. Patient registration
2. Test management
3. Result entry
4. Report generation

Later, it may require:

1. Inventory
2. Outsourcing
3. Patient portals
4. Hospital integration
5. Pharmacy integration

A scalable platform makes this transition easier.

Choosing the Right LIS for Your Laboratory

Before selecting laboratory management software, start by mapping your current workflow.

Ask yourself:

How are patients currently registered?

How are tests selected?

How are samples tracked?

Who enters results?

Who reviews results?

Who approves reports?

How are reports delivered?

How is inventory managed?

What happens when a test is outsourced?

Which processes create the most delays?

These answers will help identify what your laboratory actually needs.

Do not choose software simply because it has the longest feature list.

Choose a system that solves your real operational problems.
