How long are the test cassettes stable when stored in the refrigerator?
When stored, refrigerated at 2-8°C (36°-46°F), the cassettes are stable and can be used until the expiration date printed on the cassette pouch and box. Cassettes can be taken out of the refrigerator and stored at room temperature for thirty (30) days.
How long are the test cassettes stable once brought to room temperature in the foil pouch?
STORAGE and HANDLING The cassettes may be stored for up to 30 days at room temperature. The new expiration date must be placed on the cassette box. Once the cassettes have been stored at room temperature they must not be returned to the refrigerator.
How often should the liquid quality control material levels 1 and 2 be run?
1. Two levels of controls must be run on each day of patient testing. If an analyzer is moved to a different location, a new set of controls must be run for that day at the new location.
What is an Optics check?
The Optics Check Cassette performs a check on the optical system of the LDX analyzer based on known reflectance values encoded in the cassette. The manufacturer recommends that the optics check should be run once a day before patient samples are tested as well as after the LDX analyzer has been moved or serviced.
What is a Cholestech LDX screening?
The Cholestech LDX™ System is an efficient and economical point-of-care testing system for measuring cholesterol and related lipids, and blood glucose. It serves as a diagnostic tool that provides information for immediate risk assessment and therapeutic monitoring of cardiovascular disease and diabetes.
What does the Cholestech LDX test for?
The Alere Cholestech LDX® System combines enzymatic methodology and solid- phase technology to measure total cholesterol, HDL cholesterol, triglycerides and glucose. Samples used for testing can be whole blood from a fingerstick (collected in a lithium heparin-coated capillary tube) or venipuncture.
How often should glucose monitors have QC checks?
– If it is a machine, QC must be performed EVERY day of patient testing. Two QC samples, Level 1 (Low) and Level 3 (High) MUST be performed satisfactorily, once every 24 hrs.
How often should you calibrate a glucometer?
Calibrating 3-4 times per day can optimize sensor performance. To calibrate, you must use a fingerstick blood sample to test your blood glucose (BG) on your meter and then enter that value into your pump.
How frequently is the optic quality control conducted on the Cholestech exam?
once per monthOptic check Cartridge QC is reviewed once per month by the POCC or designee. It is reviewed and corrective action initiated in accordance to Lab-0170 Quality Control and Lab-0135 Quality Assurance for Laboratory Testing.
