# Order lab tests, collect samples and verify results

> The NduMed lab workflow from order to verified result: placing orders, collecting samples, printing labels, entering results, critical values and second-person verification.

NduMed tracks every lab test from the doctor's order to a verified result. Each test on an order moves through four stages, and only **verified** results are shown to clinicians.

| Stage | Shown as | Who acts |
| - | - | - |
| Pending | Awaiting collection | Lab technician collects the sample |
| Collected | Collected | Lab technician enters the result |
| Resulted | Awaiting verification | A **different** lab technician verifies |
| Verified | Verified | Visible to doctors and nurses |

## Order lab tests (doctors)

**1. Open the encounter**

The encounter must not be closed.

**2. Select Order labs**

Choose the **Priority**: Routine, Urgent or STAT.

**3. Pick tests and place the order**

Tick the tests and select **Place order**.

> [!NOTE]
>
> Each test is charged to the patient's bill at its catalogue price as soon as it is ordered.

## Collect samples (lab technicians)

1. Open **Lab worklist**.
2. Find the test and select **Collect sample**. NduMed assigns an accession number.
3. Select **Print label** to print a 4 x 2 inch sample label.

## Enter results

1. Open **Lab results** (the result bench).
2. Select **Enter** on a collected test and type the numeric value.
3. NduMed flags the value against the test's reference range for the patient's sex and age: **Normal**, **Low**, **High**, **Critical low** or **Critical high**.

> [!WARNING]
>
> A **critical** value sends an email alert to the ordering doctor straight away. The email contains a pointer to NduMed, not the result itself.

## Verify results

A second lab technician reviews the entered value and selects **Verify**. If you try to verify a result you entered yourself, NduMed refuses with "A different person must verify a result you entered." This four-eyes check is required.

## View and print a patient's results

Doctors and nurses open **Lab results** from the encounter screen to see the patient's verified results, including results imported from your previous system. Select **Print report** for a printable **Laboratory report**.

> [!TIP]
>
> If a result is missing, check the lab worklist: it may still be awaiting collection, entry or verification.
