Availability:

Publicly available

Description:

Measure of plasma lipid levels in blood samples to predict risk for the development of heart attack or to define metabolic syndrome.

Protocol:

1. Has a doctor or nurse ever said that you have high blood cholesterol?

[] 1 No

[] 2 Yes

[] 8 Not sure

2. Have you ever taken medication for high blood cholesterol?

[] 0 No

[] 1 Yes, now

[] 2 Yes, not now

[] 9 unk

If yes, then…

At what age did you begin taking medicine for this? __ __

[] 99 unk

Use appropriate or current lipid quality control program to complete a lipid profile.

For information on blood collection and processing, and lipid and lipoprotein determinations, refer to the Atherosclerosis Risk in Communities (ARIC) study manuals 7 and 8.

Diagnostic Criteria:

Total Cholesterol (mg/dL) LDL Cholesterol (mg/dL) HDL Cholesterol (mg/dL) Triglyceride (mg/dL)
<200 = Desirable <100 = Optimal <40 = Low <150 = Normal
200 - 239 = Borderline high 100 - 129 = Near optimal/above optimal >60 = High 150 - 199 = Borderline high
>240 = High 130 - 159 = Borderline high 200 - 499 = High
160 - 189 = High >500 = Very high
>190 = Very high

Personnel and Training Required

An interviewer who is trained to conduct personal interviews with individuals from the general population is required. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews.* The interviewer should be trained to prompt respondents further if a "don't know" response is provided.

*There are multiple modes to administer this question (e.g., paper-and-pencil and computer-assisted interviews).

The blood draw and processing procedures should be performed by a certified laboratory technician or a phlebotomist.

Equipment Needs

For the blood draw procedure, you will need the following: disposable plastic gloves; a test tube rack; three sterile, disposable 21 gauge butterfly needles; a plastic vacutainer tube guide; three vacutainer Luer slip adaptors; sterile alcohol swabs; gauze sponges; a tourniquet; bandages ("Band-Aids"); a styrofoam ice water bath; biohazard bags; a stopwatch; and eight blood collection tubes (13 ml red and gray stoppered tube, 7 ml siliconized red stoppered tube, 7 ml red and yellow stoppered tube, two 4.5 ml blue stoppered tubes, two 10 ml lavender stoppered tubes, 3 ml lavender stoppered tube).

For the blood handling and processing you will need: a freezer/refrigerator; a centrifuge; three 12 x 75 mm clear white polypropylene test tubes; three 1.5 ml yellow polypropylene microsample tubes; three 1.5 ml red polypropylene microsample tubes; one 1.5 ml green polypropylene microsample tube; six 1.5 ml blue polypropylene microsample tubes; twelve 2 ml white polypropylene screw top vials; ten lavender screw caps for 2 ml vials; two brown screw caps for 2 ml vials; one Millipore Millex HA-4 filter; one 5 ml syringe; one Centricon 30 molecular filter; and six plastic transfer pipets.

For shipping specimens, you will need the following: four 3" x 6" storage bags and one 6" x 6" storage bag; appropriately labeled styrofoam boxes.

Requirements

Requirement CategoryRequired
Average time of greater than 15 minutes in an unaffected individualNo
Major equipmentYes
Specialized requirements for biospecimen collectionYes
Specialized trainingYes

Mode of Administration

Self-administered

Life Stage:

Adult

Specific Instructions:

If the respondent answers "yes" to question 1, then the interviewer will proceed to question 2. The use of lipid-lowering medications must be captured, as the use of medications can have profound and predictable effects on the lipid levels and obscure the levels and phenotype of hyperlipidemia. Lipid profiles involving triglyceride-level measurement should be collected after an 8–12 hour fast. Generally, total cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides should be measured in a laboratory that is certified and referenced to a regional reference laboratory.

Definition

Measure to identify lipid levels in samples of blood.

Purpose

A lipid profile is used to determine if an individual is at risk for the development of coronary heart disease (CHD). A lipid profile has been shown to be a good indicator of risk for a heart attack or stroke caused by blockage of blood vessels or hardening of the arteries.

Selection Rationale

These protocols were selected because together they obtain a personal history of high blood cholesterol as well as medication usage. These two components are vital in interpreting the results of a lipid profile. Completion of a lipid profile provides specificity to determine risk of a heart attack or stroke.
