Apolipoprotein A1 (AP0A1) is not one of the blood tests, and an Apolipoprotein A1 (AP0A1) test result of 1.65 g/L is abnormal. Apolipoproteins are components of lipoproteins, and ApoA1 is one of the important components of Lipoprotein A. The ApoAI test is one of the tests for lipids, not a routine blood test. ApoA1 can be used to directly assess the level of HDL in the body. In general, the normal reference value for the male population is 1.25~1.59g/L, while the normal reference range for the female population is 1.31~1.60g/L. Therefore, a result of 1.65g/L is abnormal for both men and women. Elevated ApoA1 is of relatively minor clinical significance, as it can be physiologically increased by pregnancy, prolonged exercise, prolonged alcohol consumption, etc., and also by the use of medications such as estradiol; what is of greater clinical concern is the reduction of this indicator, which usually implies an increased risk of cardiovascular and cerebral vascular diseases, and can be caused by diabetes mellitus, chronic hepatitis, and a high cholesterol diet. In case of dyslipidemia, it is recommended to monitor the lipid profile on a regular basis, and to have it checked and treated under the supervision of a physician.
