HDL-2-cholesterol

The two-step precipitation method can measure HDL2 and HDL3. The first step is to determine HDL-C; the second step is to precipitate HDL2 containing more lipids, and HDL3-C in the supernatant can be used to calculate HDL2-C based on total HDL-C. Preferably, the two-stage precipitation uses two concentrations of the same reagent as a precipitant. Basic Information Specialist classification: cardiovascular examination classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Found in low-lipoproteinemia, anemia, sepsis, hyperthyroidism, liver disease, severe infections, malnutrition, tuberculosis and advanced cancer, as well as the intake of drugs such as p-aminosalicylic acid, kanamycin, heparin, vitamin C. Normal value: High-density lipoprotein 2-cholesterol: 3.12-5.20mmol/L Above normal: Found in hyperlipidemia, atherosclerosis, diabetes, nephrotic syndrome, hypothyroidism, common bile duct obstruction, high blood pressure (partial), and intake of vitamin A, vitamin D, oral contraceptives and other drugs. negative: Positive: Tips: Check the first day after 8:00 pm fasting, can not help but water. Normal value HDL2-C accounts for about 1/3 of HDL-C in total HDL-C, and female HDL2-C is slightly higher than male. Due to inconsistent methods, the data reported by the various companies are quite different. Adult cholesterol 2.86 ~ 5.98 mmol / liter (110 ~ 230 mg / deciliter) Children's cholesterol 3.12 ~ 5.20mmol / L (120 ~ 200mg / dl). Clinical significance Abnormal result Increased: seen in hyperlipidemia, atherosclerosis, diabetes, nephrotic syndrome, hypothyroidism, common bile duct obstruction, high blood pressure (partial), and intake of vitamin A, vitamin D, oral contraceptives and other drugs. Reduction: seen in hypolipoproteinemia, anemia, sepsis, hyperthyroidism, liver disease, severe infection, malnutrition, tuberculosis and advanced cancer, as well as intake of drugs such as p-aminosalicylic acid, kanamycin, heparin, vitamin C, etc. . High results may be diseases: hyperlipidemia, atherosclerosis considerations At the time of examination: the test should be carried out under the condition that the physiological and pathological conditions are relatively stable, and there should be no acute attack within 4-6 weeks. Before the test: Do not take certain drugs, such as birth control pills, certain antihypertensive drugs, etc., which may affect blood lipid changes, resulting in errors in testing. The first day of the inspection, after 8:00 pm, fasting, can not help but water. The original regular diet should be maintained before blood draw and the body weight should be kept constant. On the first night of the examination, you must rest well, entertain until midnight and even overnight. Check the blood pressure and blood lipids the next morning. Inspection process Inspection method: draw blood and check blood lipids. Not suitable for the crowd no. Adverse reactions and risks no.
