There are seven commonly used lipid tests: cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, lipoprotein (a), apolipoprotein A, apolipoprotein B. So do you know their significance? 1, cholesterol (TC, CHO) reference values: appropriate level: ≤ 5.17mmol/L (200mg/dL); critical range: 5.20 ~ 5.66mmol/L (201-219mg/dL); elevated: ≥ 5.69mmol/L (220mg/dL); elevated: CHO elevated hazards: easy to cause atherosclerotic heart and Cerebrovascular diseases such as: coronary heart disease, myocardial infarction, stroke (stroke), etc. Diseases with elevated CHO: various hyperlipoproteinemia, obstructive jaundice, nephrotic syndrome, hypothyroidism, chronic renal failure, diabetes mellitus, etc. Physiological factors that lead to elevated CHO: high-fat diet, smoking, alcohol consumption, stress, and blood concentration. It may be significantly elevated in the last trimester of pregnancy and may recover after delivery. Decrease: CHO decrease can be seen in various lipoprotein-deficient states, cirrhosis, malignancy, malnutrition absorption, and megaloblastic anemia. It can also be reduced during menstruation in women. 2, triglycerides (TG) reference value: appropriate level: <1.69mmol/L (150mg/dL); critical range: 1.69 ~ 2.25mmol/L (150-200mg/dL); elevated: 2.26 ~ 5.63mmol/L (200-500mg/dL); very high: ≥5.64mmol/L (500mg/dL); elevated: TG dL); Elevated: Hazards of elevated TG: triglycerides are also a risk factor for the development of coronary heart disease and should also be given dietary control or medication when they are elevated. common diseases with elevated TG: various hyperlipoproteinemia, diabetes, gout, obstructive jaundice, hypothyroidism, pancreatitis, etc. Decrease: seen in hypolipoproteinemia, malnutrition absorption, hyperthyroidism, also seen in excessive hunger, exercise, etc. 3, high-density lipoprotein cholesterol (HDL-C) reference value: appropriate level: ≥ 1.04mmol/L (40mg/dL); reduced: ≤ 0.91mmol/L (35mg/dL); HDL-C is considered as "good cholesterol" because it can transport free cholesterol accumulated in tissues to the liver, reducing tissue HDL-C is considered as "good cholesterol" because it can transport free cholesterol accumulated in tissues to the liver, reduce cholesterol deposition in tissues, and play an anti-atherosclerotic role. Therefore, individuals with low HDL-C levels have an increased risk of developing coronary heart disease, while those with high levels are less likely to develop coronary heart disease. 4, LDL-C reference value: appropriate level: ≤3.10mmol/L (120mgd/L); borderline elevated: 3.13-3.59mmol/L (121-139mg/dL); elevated: ≥3.62mmol/L (140mg/dL); elevated: seen in hereditary hyperlipoproteinemia, thyroid function hypothyroidism, nephrotic syndrome, obstructive jaundice, chronic renal failure, Cushing's syndrome, etc. The risk of elevation: Elevated LDL is one of the important risk factors for the development of atherosclerosis, and is used to determine the risk of coronary heart disease and is the primary indicator for the prevention and treatment of dyslipidemia. Decrease: It can be seen in the absence of β-lipoproteinemia, hyperthyroidism, digestive malabsorption, liver cirrhosis, malignant tumor, etc. 5, lipoprotein (a) reference value: 10 ~ 140mmol / L (0 ~ 300mg / L) pathological elevation: ≥ 300mg / L; Lp (a) elevation increases the risk of atherosclerosis and arterial thrombosis, and its increased concentration is an independent risk factor for atherosclerotic cardiovascular disease. 6, apolipoprotein A (apoA) reference value: 1.20 to 1.60g/L In general, apoA Ⅰ can represent HDL level, which is significantly and positively correlated with HDL-C. People with lower than 1.20g/L have a tendency to develop coronary heart disease than those with higher than 1.60g/L. 7, apolipoprotein B (apoB) reference value: 0.80~1.20g/L apoB mainly represents LDL level, and is significantly positively correlated with LDL-C. elevated apoB is a risk factor for coronary heart disease, higher than 1.20g/L than less than 1.00g/L has a tendency to develop coronary heart disease, lowering apoB can reduce the onset of coronary heart disease and promote the regression of atheromatous plaque.
