What does the Cholestech LDX System measure?
Using patented, innovative technology, the Cholestech LDX System measures the levels of TC, HDL and triglycerides, calculates the TC/HDL ratio and estimates of LDL and VLDL. The health care provider can now share test results with the patient on the spot, at a key “teachable moment”.
What is Cholestech LDX test?
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.
Which of the following is the appropriate method for collecting blood for a Cholestech LDX screening?
Samples used for testing is whole blood from a fingerstick (collected in a lithium heparin-coated capillary tube.
How often should the optics check cassette be tested?
once a day
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. The Optics Check Cassette is reusable until its expiration date. When not in use, it should be stored at room temperature in the case provided.
How do I use Cholestech?
Cholestech LDX®: Place the sample into the cassette well. Be sure to apply the sample within 8 minutes or the blood will clot. Keep the cassette flat after the sample has been applied. WARNING: Allowing the sample to sit in the cassette will cause inaccurate results.
How long can the sample sit in the test cassette before inserting into the Alere Cholestech LDX Analyzer tray?
10 minutes
Do not reuse cassettes. Cassette Handling Cassettes should sit at room temperature for 10 minutes before opening the pouch. Use the cassette as soon as the pouch is opened. Sample Type The Alere Cholestech LDX® System is CLIA waived for fingerstick or venous whole blood unprocessed samples only.
How accurate is CardioChek?
Results: The CardioChek PA analyzer was substantially inaccurate for LDL cholesterol (-25.9% bias), HDL cholesterol (-8.2% bias) and TC (-15.9% bias). Moreover, those patients at higher risk of complications from hyperlipidaemia were most likely to be misclassified into a lower risk category.
What does HDL do to cholesterol in the blood?
HDL (high-density lipoprotein), or “good” cholesterol, absorbs cholesterol and carries it back to the liver. The liver then flushes it from the body. High levels of HDL cholesterol can lower your risk for heart disease and stroke.
Can you test cholesterol with finger stick?
At a clinical cut-point of TC ≥ 200 mg/dL, the fingerstick measurement had 79% sensitivity to categorize participants as having abnormal cholesterol and 95% specificity to categorize participants as having normal cholesterol levels.
How long can sample stay in capillary tube?
“The way the blood is initially collected and how it’s transported and stored affect its long-term viability.” For example, a wet blood sample that has been collected via a traditional phlebotomy blood draw into vials or tubes cannot remain at room temperature longer than eight hours.
How accurate is home cholesterol test?
The results of home cholesterol tests are about 95% accurate — very close to the accuracy of a doctor’s (or laboratory’s) test.
