Lab software that knows where every sample is right now
A test catalogue with prices and reference ranges, barcoded sample tracking from collection to report, signed PDF reports on WhatsApp, referring doctor records and a phlebotomist app for home collections.
Diagnostic lab software, often called a laboratory information system, registers patients, tracks each sample from collection to result, produces signed reports and handles billing for walk-ins, doctors and partner clinics. We build it for independent pathology labs, diagnostic centres, and labs running collection centres or home-collection teams in India.
Where the day goes wrong
- 01
Samples that go missing
A tube drawn at a collection centre or a home visit is unaccounted for until the patient calls to ask why the report is late.
- 02
Reports chased by phone
Patients and doctors ring the front desk for reports all day, and staff spend hours printing, scanning and forwarding PDFs.
- 03
Home collection cash
Phlebotomists collect payment at the door, and reconciling who collected what from whom becomes a weekly headache.
- 04
Tests done, not billed
An extra test added after a doctor's phone call is run on the analyser but never added to the bill.
- 05
Send-out tests forgotten
Samples sent to a reference lab are tracked on paper, so delays and their costs surface late.
What we build for you
- 01
Test catalogue
Tests and packages with sample type, container, turnaround time, reference ranges by age and sex, and separate price lists.
- 02
Barcoded sample tracking
Labels printed at collection, status at every hand-off, and rejections and re-collections recorded with the reason.
- 03
Results and signed reports
Results entered or imported from supported analysers, validated by the pathologist and issued as signed PDFs with a verification QR.
- 04
WhatsApp report delivery
Reports sent to the patient and, with consent, the referring doctor, with a link to earlier reports.
- 05
Referrer and B2B accounts
Referring doctors, partner clinics and corporate clients with their own price lists, credit terms and monthly statements.
- 06
Home collection app
Slots, routes, collections confirmed with time and location, payment capture and sample handover at the lab.
A day in a diagnostic lab
Imagine a pathology lab in Trichy with a main laboratory, four collection centres and two phlebotomists on bikes for home visits. By eight in the morning, fasting patients are queuing at every centre, home visits have begun and the first courier is heading to the main lab. Each sample needs the right tube, a label that cannot be confused with another patient's and a record of when it was drawn. By afternoon, results are coming off the analysers, the pathologist is checking abnormal values, and the front desk is fielding calls from patients and doctors asking whether reports are ready.
Losses a lab owner rarely sees
Most lab owners know their test prices well and their losses badly. Tests added verbally after registration are run but never billed. A sample is rejected for haemolysis and the re-collection visit goes free because nobody recorded why it was needed. Home-collection cash reaches the lab a few days late, or slightly short. Send-out tests are paid for at the reference lab and sometimes billed to the patient at an outdated price. And every report that reaches a doctor late gives that doctor a reason to recommend another lab next time.
Following the sample
Registration creates the bill and prints a barcode label for each tube, so the tube carries the patient's identity from the first minute. Each hand-off, from collection to courier to accession to analyser, updates the sample's status. Results are entered by hand or, where your analyser supports a data interface, imported directly; we check each machine model before promising that. The pathologist validates, the report is generated as a signed PDF with a QR code for verification, and it reaches the patient through the WhatsApp Business API. Copies go to the referring doctor when the patient agrees.
For home visits, a phlebotomist app shows the day's route, confirms each collection with time and location, records payment and logs the handover at the lab. It is the kind of field staff app we build for teams on the move: simple screens, offline storage and a sync when the signal returns.
Lab software is not hospital software
A standalone lab does not need wards, pharmacy or consultation records. If your lab sits inside a hospital, the lab module of our hospital management software fits better. For an independent lab, a focused system costs less and goes live sooner.
Price and build time for a lab
A single-lab system with registration, sample tracking, results, signed reports and WhatsApp delivery typically starts around ₹85,000. Labs with collection centres, B2B accounts and analyser interfacing usually land between ₹1,50,000 and ₹5,00,000. The phlebotomist app typically starts around ₹65,000. Allow 8 to 14 weeks for the lab system and 6 to 8 weeks for the app.
A sensible first step
If your staff spend their day sending reports, start with report delivery: signed PDFs on WhatsApp with a verification QR, connected to your existing billing. If home collections are growing faster than the front desk can coordinate them, the phlebotomist app is the better first project. A small lab with one technician and a handful of tests a day can manage with a ready-made lab package, and should. A custom system from VS Tech Builders earns its cost once samples, centres and people have multiplied faster than your paperwork.
Frequently asked questions
Can results come directly from our analysers?
Often, yes. Many modern biochemistry and haematology analysers can send results through a data interface, and where yours does, results flow into the patient record without retyping. Older machines or closed systems may not allow it, and then results are entered manually with range checks. We review each analyser model during discovery and tell you plainly which ones can be connected.
Is it safe to send medical reports on WhatsApp?
It is common practice in India, and it is safe enough when done properly. Reports go only to the mobile number the patient registered, through the official WhatsApp Business API rather than a staff member's phone, and each PDF carries a QR code that confirms it came from your lab. Consent to share reports with a doctor is recorded at registration.
Can referring doctors and partner clinics see their patients' reports?
Yes, with the patient's consent. Each referring doctor or clinic gets a login or an automatic copy of reports for the patients they sent. Partner clinics and corporate clients can also have their own price list, credit terms and a monthly statement. The lab sees referral volumes by source, which shows which relationships are growing and which need attention.
How does the home collection app handle cash?
The phlebotomist records the payment mode for each visit: cash, UPI or already paid online. At the end of the round the app shows the cash due to the lab, the front desk confirms receipt, and any difference is visible the same day rather than at month end. Patients receive a WhatsApp receipt immediately, which also heads off disputes later.
