Built around how a lab already works

Every part of the tool mirrors a step your lab already takes — from picking a test panel to handing a patient their bill.

REPORTING

Department and test templates

Biochemistry, hematology, clinical pathology and more — organized the way your lab already thinks about panels, so entry is quick and consistent.

PRINTING

Letterhead-aligned output

Set your top and bottom margins once to match your pre-printed letterhead, and every report lines up correctly — no re-measuring, no wasted paper.

BILLING

Receipts, without a second tool

Generate a matching bill alongside the report, with your lab's own pricing — no need to re-enter the same patient and test details elsewhere.

ACCESS

A password, set by you

Lock the tool with your own password on first use. Your reports and settings are saved locally in the browser you're using it in.

From blank report to printed bill in three steps

1

Pick the panel

Choose a department and test, and the tool fills in standard parameters, reference ranges and units — ready to edit.

2

Enter results

Type in patient details and results. Anything abnormal is easy to flag, and the report saves itself as you go.

3

Print and bill

Print the report on your letterhead, and generate the matching bill in the same format — no retyping.

You own the copy, not a subscription to it

The tool is a single file that runs entirely in your browser. There's no ongoing account, no data sent to a server, and no dependency on us staying online for you to keep using it.
