Test Overview
Test Methodology

Cholestech LDX - combination of enzymatic methodology and solid phase technology

Test Usage

Performed at authorized locations by point of care operators. Includes Total Cholesterol, HDL Cholesterol, Triglycerides, calculated LDL, calculated non-LDL,
Cholesterol HDL ratio, and Glucose.
Cholesterol- aids in the diagnosis and treatment of disorders involving excess cholesterol and lipoprotein metabolism disorders. HDL- lipid disorders, atherosclerosis, and various liver and renal diseases. Triglyceride- useful in patients with; diabetes mellitus, nephrosis, liver obstruction, lipid metabolism disorders. Glucose- carbohydrate metabolism disorders, and pancreatic islet cell carcinoma.

Reference Range *

Analyte reference ranges are available in the Cholestech test procedure located on the POC website: https://www.pathology.med.umich.edu/point-of-care.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

•Any value outside the linear limits of the analyzer will be reported with a (>) or (<), refer to test procedure for analyte specific reporting limits.
•If the measure value of the total cholesterol, HDL or triglycerides is outside the measuring range, instrument will not give an LDL estimate.
•A triglyceride of >400 will not have an LDL estimate.
• A triglyceride of >650 will not have an HDL result.
•The glucose test is specific for D-glucose. Other sugars that may be present in the blood do not react in the glucose test (I.e., fructose, lactose).
•Values outside of the measuring range should be sent to main laboratory for testing.
•Some substances may cause interference with enzymatic tests. See package insert for a complete listing of possible interferants.
•Blood collection tubes with glycerol should not be used.
•Hand creams and soaps with glycerol may cause falsely high triglyceride results.
