How to move your lab from Excel to LIS software

Thousands of Indian pathology labs still run on an Excel sheet for registration, a Word template per test for reports and a paper register for billing. It works until the lab grows: reports get retyped, the wrong template gets printed, referrer statements take a weekend, and nobody can find last March's report for a returning patient. Moving to LIS software (lab management software) fixes this, but the move itself worries most owners. This guide is the plan we follow with labs moving to PathLab Software; it works for any LIS.

Step 1: Decide what you are moving

You do not need to move everything. Most labs move four things and leave the rest:

• Test master: every test and panel you offer, with price, sample type, container, department and method.
• Reference ranges: by age band and sex, with units.
• Referrer rate lists: each doctor, clinic or corporate client with their agreed prices.
• Patient list: name, age or date of birth, sex, phone number and, if you have it, past report PDFs.

Old Excel result rows rarely need to become structured data. Keep old reports as PDFs, searchable by patient, and start structured results from go-live day.

Step 2: Clean the test master first

The test master is the foundation; a messy one causes problems for years. Open your rate card and your Word templates side by side and fix three things.

1. One name per test. "Sugar F", "FBS" and "Glucose Fasting" should be one test with the other names as aliases.
2. Panels made of tests, not text. A lipid profile should be a panel of five or six tests, each with its own range, so delta checks and repeat reminders work per test.
3. Units decided once. Platelets in lakh/µL or in /µL, haemoglobin in g/dL. Pick what your pathologist signs off and use it everywhere.

Most LIS products, PathLab Software included, come with thousands of tests pre-loaded. It is usually faster to start from that list and switch on what you offer than to type your own from scratch.

Step 3: Check reference ranges with your pathologist

Excel-era labs often have ranges that were copied from a kit insert years ago and never reviewed. Print the range list, sit with your pathologist for an hour and confirm each one by age band (newborn, child, adult, elderly where relevant), sex and pregnancy for the tests where it matters. This is also an ISO 15189 requirement if you plan an NABL assessment; the NABL software checklist explains why range history matters.

Step 4: Export referrers and rate lists

List every referring doctor and clinic with a WhatsApp number, their rate list or discount, and how they want reports: all, abnormal only or none. This is the moment to write down rate-list arrangements that live only in someone's memory, and to check them against the law: paying doctors for referrals is restricted in India under NMC professional-conduct regulations and state rules. In PathLab Software each referrer gets a rate list and an automatic monthly statement, sent through the referring-doctor WhatsApp desk.

Step 5: Prepare the patient list

Export patients to a single sheet with one row per person: name, date of birth or age, sex, phone number, and an ID if you used one. Remove obvious duplicates, but do not spend days on it; a good LIS flags likely duplicates at registration. If you have past reports as PDFs or Word files, put them in folders named by patient ID or phone number so they can be attached.

Step 6: Set up the report

• Header with your logo, address, registration details and accreditation status written correctly.
• Pathologist's name, qualification and signature image (or DSC).
• Report language: English, Tamil or both, per patient or per referrer.
• QR verification so printed and forwarded copies can be checked.
• Department-wise layout and the comments your pathologist uses most.

Print a test report for a CBC, a lipid profile and a thyroid profile and get them signed off before go-live.

Step 7: Connect analyzers and printers

Install the barcode label printer and print test labels on the actual tubes you use. Then connect analyzers: LAN analyzers need the connector's IP and port in their LIS settings; serial analyzers need the right cable and settings. Run three known samples on each analyzer and confirm results land on the right patient with the right units. The analyzer interfacing page has per-model notes.

Step 8: Train in roles, not all at once

Front desk staff need registration, barcodes, billing and dues. Technicians need the worklist, result entry and reruns. The pathologist needs validation, flags and delta checks, including from a phone. Owners need reports, referrer statements and the audit trail. Thirty to sixty minutes per role, on your own machines and in the language staff are comfortable in, is enough.

Step 9: Run in parallel, briefly

Run the new system alongside Excel for one to three days, not weeks. Register every patient in the LIS, keep the old sheet for cross-checking, and compare totals at the end of each day: patients, tests, amount collected. Long parallel runs double the work and staff quietly go back to the old way. Once two consecutive days match, stop the Excel sheet.

Step 10: Go live and review after one week

On go-live day, keep someone from the vendor on call. After a week, review: unmatched analyzer results, reports amended after release, referrers who did not receive reports, and any test that was hard to find at registration. Fix the test master and templates, not the habits, and the system settles quickly.

How long does the move take?

Common mistakes

• Typing the old test list by hand instead of starting from the pre-loaded master.
• Migrating years of Excel results as structured data, which takes weeks and adds little.
• Skipping the pathologist review of reference ranges.
• Going live on the busiest day of the week.
• Letting staff share one login, which breaks the audit trail from day one.

PathLab Software does the data loading, report setup, analyzer connection and training free on every plan, so most single-branch labs are live in about two working days. See PathLab Software pricing or read about what lab management software does before you start.

Questions people ask

Can I import my Excel patient list into lab software?

Yes. Most LIS products import a CSV or Excel sheet with one row per patient. PathLab Software loads your patient list, test master and referrer rate lists for you before go-live, free, and attaches old report PDFs so they stay searchable by patient.

Will I lose my old reports when I switch?

No. Keep old reports as PDF files attached to each patient rather than converting them into structured data. In PathLab Software they stay searchable by patient name or phone, and new results from go-live day are stored as structured data with delta checks.

How long should I run Excel and the new LIS in parallel?

One to three days is enough. Compare daily totals of patients, tests and collections; once two consecutive days match, stop the Excel sheet. Longer parallel runs double the work and staff tend to drift back to the old system.

Does moving from Excel to LIS software cost extra?

It depends on the vendor; some charge onboarding fees of ₹10,000 or more. PathLab Software charges no setup or migration fee on any plan, and plans start at ₹1,999 a month plus GST after a 14-day free trial.
