Apolipoprotein B (ApoB) is one of the largest proteins in the body. Serum Apo B is mostly in the range of 0.8 to 1.1 g/L in normal population. Apo B1.29 g/L is slightly higher than the reference value, you should consult a doctor in time, under the guidance of the doctor to adjust the diet, appropriate exercise, and take drugs if necessary. There are two types of Apo B, Apo B₄₈ and Apo B₁₀₀, the former is mainly found in celiac microparticles (CM) and the latter is mainly found in low-density lipoprotein (LDL). Unless otherwise specified, routine clinical measurement of Apo B usually refers to Apo B₁₀₀. Serum Apo B mainly reflects the level of LDL, which is significantly and positively correlated with the level of serum LDL-C, and the clinical significance of the two is similar.Increased LDL-C is a major risk factor for the development and progression of atherosclerosis. When LDL B1.29g/L is found, there is no need to be overly alarmed, and you can go to a regular hospital to see a doctor to clarify whether it is caused by pathological factors, so as to take positive measures to improve the quality of life.
