Hospital Lab (LIS) Workflow: Order to Report Explained

How a Laboratory Information System (LIS) takes a test order from doctor to sample collection, processing and a verified report — and where it connects to billing.

A lab order that starts as a doctor's instruction and ends as a signed report touches several hands along the way — the ordering doctor, sample collection, the lab technician processing it, and whoever verifies and releases the result. A Laboratory Information System (LIS) exists to keep that chain connected electronically instead of relying on paper requisition slips and manually delivered reports.

The order-to-report workflow

How a lab order moves

Order placed

From OPD or IPD

Sample collected

Tagged to the order

Processing

Results entered

Verified & released

Report reaches the doctor

Each step should update the same order record rather than creating disconnected paperwork — a doctor checking a patient's chart should see whether a test is ordered, collected, in-process, or reported, without calling the lab to ask.

Priority and turnaround

Not every test is equal. Emergency and stat orders need to visibly jump the queue ahead of routine tests, and a lab worklist should make that priority obvious rather than relying on the lab technician remembering which orders were urgent.

Where lab connects to the rest of the hospital

A lab order for an admitted patient should post its charge to that patient's running IPD bill automatically — see our IPD billing guide. For radiology, which follows a very similar order-to-report shape with imaging in place of a physical sample, see our radiology workflow guide.

The paper slip is the tell

A simple way to judge whether a lab is genuinely digitized: does a printed requisition slip still physically travel from the ward to the lab? If it does, the order-tracking, the priority flagging and the automatic billing described above aren't actually connected yet — they're running alongside a paper process rather than replacing it, which means every one of those benefits depends on someone remembering to also update the digital record.

How Uyirly runs the lab

Uyirly's lab follows every sample by barcode from collection to a verified report. A test ordered in a consultation appears on the lab worklist with no paper slip; the technician enters results against the reference ranges, which flag high and low values automatically; a pathologist verifies before anything is released; and the letterhead PDF report is delivered to the patient by WhatsApp or a patient portal.

  • Barcoded samples with a live worklist of pending, in-process and verified tests.
  • Reference ranges flag abnormal values automatically.
  • Verified reports become clean letterhead PDFs, delivered without a second visit.
  • Walk-in and ward orders both bill to the right patient with no re-registration.

The lab runs standalone or inside Uyirly's hospital management software, sharing the patient record with OPD and radiology. You can start a 30-day free trial with no credit card.

Frequently asked questions

What is an LIS in hospital software?

LIS stands for Laboratory Information System — the module that manages test orders, sample tracking, processing and report generation for a hospital lab, connected to the same patient record as everything else.

How does a lab order reach the lab without a paper slip?

When a doctor orders a test from OPD or IPD, it should appear directly in the lab's order queue electronically, tagged to the patient and the ordering doctor — no printed requisition needs to physically travel to the lab.

Does the lab report automatically appear on the patient's bill?

It should. Once a test is ordered, its charge can post to the patient's bill immediately (OPD) or to the running IPD bill, so billing doesn't require the lab and billing desk to reconcile separately at the end of the day.
