A diagnostic lab has one failure mode that matters more than all the others: the wrong result attached to the right patient, or the right result attached to the wrong one. Everything a laboratory information management system does should be judged first against whether it makes that harder.
After that, the question is commercial: how quickly can a patient get a report, and how much manual work sits between the analyser and the phone in their hand.
Sample identity, which is the safety critical part
Barcoded specimens from the point of collection
A barcode generated at registration, printed on the tube at the moment of draw, scanned at every subsequent step. Handwritten labels and manual transcription are where mix ups occur.
For labs running home collection, the label has to be printable in the field or pre generated against the booking.
Chain of custody
Who collected it, when, who received it at the lab, when it was run, on which analyser, by whom. Not bureaucracy. When a result is questioned, this record is the only way to answer.
Rejection handling
Haemolysed, insufficient volume, wrong tube, clotted. A structured rejection reason, an automatic notification to the collection point, and a recollection request. Labs without this lose samples silently and the patient finds out when the report is late.
Result authorisation
No result should reach a patient without a qualified person releasing it. The system should support:
- Auto verification for results within normal range on validated analysers, which is what makes volume possible.
- Mandatory review for anything outside range, and a hard stop for critical values.
- Critical value alerts that require somebody to record that the referring doctor was informed, with the time and the name.
- Delta checks comparing against the patient’s previous result, which catches both genuine deterioration and sample mix ups.
That last one is the single most useful safety feature a LIMS offers and it is frequently not configured.
Analyser integration
The difference between a lab that scales and one that does not. Results flowing directly from the haematology, chemistry and immunoassay analysers into the system, with no transcription.
Ask specifically which of your analysers are supported, by model, and whether the integration is bidirectional so that the worklist is sent to the machine rather than entered on it. Generic claims of analyser support mean very little.
The commercial side
- Test panels and profiles with their own pricing, not just individual tests.
- Corporate and institutional rates. A hospital, a company and a walk in patient pay different prices for the same test, and monthly invoicing for the first two.
- Referring doctor tracking and, where applicable, the commercial arrangement attached to it, recorded transparently.
- Collection centre network. Many Pakistani labs run collection points that feed a central laboratory. Each needs registration, sample dispatch, and its own revenue reporting.
- Outsourced tests sent to a reference laboratory, with the cost and the turnaround tracked against your own commitment to the patient.
Reporting and delivery
Patients in Pakistan overwhelmingly expect reports on WhatsApp, and labs that deliver them fastest win repeat business from referring doctors.
Requirements: PDF reports with the lab’s format and signature, delivery by WhatsApp, SMS with a secure link, and a portal for corporate clients. Reference ranges must be correct by age and sex, which is a detail generic systems often get wrong.
What to ask in a demo
- Register a patient, print a barcode, and receive the sample. Time it.
- Show a critical value and the alert and acknowledgement workflow.
- Show a delta check against a previous result.
- Reject a sample and show the recollection request reaching the collection point.
- Pull a result directly from an analyser you actually own.
- Send a report by WhatsApp and show what the patient receives.
- Invoice a corporate client for a month at contract rates.
Build or buy
Buy for a single laboratory with standard test menus; established LIMS products handle this well and carry validated analyser interfaces you do not want to build.
Build when you run a large collection centre network with unusual logistics, when you need deep integration with a hospital system, or when you operate several labs with shared reference testing. See hospital management software requirements for the adjacent problem and custom versus off the shelf for the threshold.
Frequently asked questions
What is the most important feature in a LIMS?
Barcoded sample identity from collection through to result, and a result authorisation workflow with critical value handling. Both are patient safety features before they are efficiency features.
Does it need to integrate with our analysers?
For any meaningful volume, yes. Manual transcription of results is both slow and the second most common source of reporting errors after sample mix ups.
How much does it cost in Pakistan?
Off the shelf systems are usually licensed per user or per site, with analyser interfaces often charged separately per instrument. Custom builds for multi site laboratory networks start considerably higher.
How long does implementation take?
Six to twelve weeks for a single lab, longer where analyser interfaces and a collection centre network are involved. Test menu configuration and reference ranges take more time than most labs expect.
