Quick Reference Guide
Introduction
The Cholestech LDX is a small, portable analyzer and test cassette system. It is easy to use, and gives fast
and reliable results. To run a test, just add a sample to the cassette and place it in the Analyzer. In a few
minutes, the results will appear on the screen.
The Cholestech LDX System is for in vitro diagnostic use only. This guide contains information intended to
familiarize and instruct the user in the proper use and care of the Cholestech LDX System.
System Components
Results from each
cassette will print out on
the Cholestech Thermal
Printer.One, two or three
labels may be printed.
Blood from a fingerstick
sample is placed into a
single-use, disposable
cassette.
Blood from a fingerstick sample
is collected into a capillary
tube with heparin anticoagulant.
The black plunger dispenses
the sample into the sample well
in the cassette.

PLEASE NOTE: Even though the Cholestech LDX is a “CLIA-waived” test system,
each laboratory or testing site using the Cholestech LDX must have a CLIA Certificate
of Waiver. To obtain a Certificate of Waiver, call your state department of health
or Cholestech for an application. Failure to operate the Cholestech LDX in
accordance with the manufacturer’sinstructions will void the waived status.
The tests will then be considered highly complex.

forms. Hold the capillary tube horizontally by the end with
the plunger. Touch it to the drop of blood without touching
the skin. Fill the capillary tube within 10 seconds.
Do not allow any bubbles to enter the capillary tube.
Dispense the Sample
Place the end of the capillary tube into
the sample well and dispense the sample
by pushing down on the plunger. Keep
the cassette level after the sample has
been applied.
Open the Drawer
Press the RUN button on the Analyzer. The cassette
drawer will open, and the screen will display:

Cassette: once each day before patient samples are
tested and after the Cholestech LDX has been moved
or serviced.
3Optics Check
Cholestech Level 1 and 2 Controls
Controls must be run
following manufacturer’s
recommendations.
Controls must be at room
temperature before
testing. Verify that the lot
number on the control vial
and the assay sheet arethe same. Mix each
vial by gently inverting 7–8 times immediately
before use. Store controls in the refrigerator when
not in use.
Testing QC Material
Use the MiniPet™Pipette
and tips to measure and
dispense the control
sample into the cassette.
Place the cassette in the
drawer immediately and
press RUN. Record results
on the Quality Control Log. Results must be within
established ranges beforepatient samples can
be tested.
How do I get a CLIA Certificate of Waiver?
Even though the Cholestech LDX is a “CLIA-waived” test system, each laboratory or testing site using the Cholestech LDX
must have a CLIA Certificate of Waiver before starting testing. To obtain a Certificate of Waiver, call your state
department of health or Cholestech Technical Service (1.800 733.0404) for an application (form HCFA-116). Cholestech
Technical Service can give you the phone number of your state department of health and assist you in filling out the
application.
Remember: The Cholestech LDX System is only waived for fingerstick or venous whole blood.
How often do I have to run the controls?
If you are testing under CLIA-waived status, you must follow the manufacturer’s recommendations for running
controls. Cholestech recommends that you run controls:
• With each new shipment of cassettes (even if cassettes arefrom the same lot previously received).
•With each new lot of cassettes.
•As otherwise required by your laboratory’s standard quality control procedures.
• If you are not running the Cholestech LDX under CLIA-waived status, or if your local or state regulations require more
frequent testing of quality control material, then quality control must be performed in compliance with those regulations.
How should I store my cassettes?
When stored refrigerated at 36–46˚F (2–8˚C), the cassettes are stable until the expiration date printed on the cassette
pouch and box. Cassettes can be stored at room temperature for 30 days. Do not use a cassette past the expiration
date. Do not return cassettes to the refrigerator once they have been stored at room temperature.
