24
- apolipoprotein B-100
Low-density lipoprotein (LDL)
25
- "good cholesterol"
High-density lipoprotein (HDL)
26
has antiatherogenic effect
High-density lipoprotein (HDL)
27
apolipoprotein A-1
High-density lipoprotein (HDL)
28
composed primarily of cholesterol esters, phospholipids
Lipoprotein a
29
- apolipoprotein a
Lipoprotein a
30
increased in coronary heart disease and myocardial infarction
Lipoprotein a
31
- increased in atherosclerosis
LDL
32
HIGH RISK OF CHD
IDL
33
increased in coronary heart disease and myocardial infarction
Lipoprotein a
34
- abnormal lipoprotein
Lipoprotein X
35
- biliary cirrhosis or cholestasis and genetic lecithin-cholesterol acyltransferase (LCAT) Deficiency
Lipoprotein X
36
- genetic lipid abnormality "FH" most closely linked to heart disease
Hypercholesterolemia
37
- FH (genetic), or the result of secondary hormonal abnormalities (DM & renal disease)
Hypertriglyceridemia
38
moderately elevated tri, VLDL,, normal LDL, Decreased HDL
familial Hypertriglyceridemia
39
- presence of elevated levels of serum total cholesterol and triglycerides
combined hyperlipidemia
40
- high total cholesterol, high triglycerides, high LDL, low HDL
familial combined hyperlipidemia (FCH)
41
Diabetes mellitus, hypothyroidism, obesity, pregnancy, nephrotic syndrome, pancreatitis, alcoholism
Secondary lipoproteinemia -
42
- elevated VLDL and Apo B- 100, normal to elevated LDL, normal or elevated triglycerides decreased HDL chole and Apo A1
Hyperapobetalipoproteinemia
43
how is hdl measured
Precipitation of LDL and VLDL/Polyanion Precipitation, followed by measurement of HDL in supernatant
44
PRECIPITATING AGENT OF HDL
Precipitating agent: sulfate-magnesium chloride sulfate-manganese chloride
45
WHERE IS FRIEDEWALD FORMULA USED AND DESCRIBE IT
Friedewald formula (indirect, not valid for triglycerides over 400mg/dL) LDL cholesterol = total cholesterol - [HDL cholesterol + triglyceride/5]
46
uses detergents to block HDL and VLDL from reacting with the dye to form a colored chromogen product.
Homogeneous assay - use
