# Requisitions

> Generate and print requisition forms for reference lab test orders in bLIS.

## Overview

A requisition is a printable form that accompanies samples sent to a reference laboratory. It includes subject information, test orders, sample details, and billing information. Requisitions are generated per accession and can be customized by selecting which samples to include.

<Note>
  Requisitions are only available when your lab has the requisitions feature enabled. Contact your lab administrator if you do not see the requisition option.
