LIS – How important is it ?

As important as a microscope.

If the LIS fails, Lab work stops

Information technology and logistics key components differentiating small and corporate labs.

Information and Communication skills are a must for today’s world.

INVENTORY MANAGEMENT

Inventory management

Record as the supplies come

Record reagents used as testing is done

The difference is inventory

Check it against average usage and order if necessary

INVENTORY MANAGEMENT

Use 2D barcode provided by the manufacturer.

Scan reagents as they arrive

LIS tells about lot and bottle use

Define re-order level

Reagent lot and bottle (Date and time of first use)

Quality management

We are expected to run 2 levels control for common tests

30 X 2 ie. 60 values obtained

Print , feed the values

Plot charts

If the day starts at 9:30 when to take corrective action and when does the work begin ?
