Normal value of pregnancy-associated protein a

Protein A is the most important trace element in the human body. It is an independent factor that plays an extremely important role in the body, especially for pregnant women. During pregnancy, if the relevant protein A value is abnormal, it will affect the fetus and the mother's body, because protein A value is an important factor in maintaining brain and heart health. You can increase your protein A intake in your normal diet, which will adjust the protein value to normal.

Lipoprotein A is mainly synthesized in the liver, and its main function is to prevent the dissolution of blood clots in blood vessels and promote the formation of atherosclerosis. Sustained increase in lipoprotein levels is closely related to angina pectoris, myocardial infarction and cerebral hemorrhage. It is an independent risk factor for coronary heart disease.

(1) Precautions before blood collection

① Do not eat greasy or high-protein food and avoid drinking large amounts of alcohol the day before blood collection. The alcohol content in the blood will directly affect the test results.

② After 8 pm the day before the physical examination, you should start fasting for 12 hours to avoid affecting the test results.

③ Relax when drawing blood to avoid blood vessel contraction due to fear, which will increase the difficulty of blood collection.

(2) Things to note after blood draw

① After drawing blood, apply local pressure on the needle hole for 3-5 minutes to stop the bleeding. Note: Do not rub to avoid causing subcutaneous hematoma.

② The pressing time should be sufficient. The clotting time varies from person to person, and some people need a little longer to clot. Therefore, if you stop applying pressure immediately when the surface of the skin seems to be not bleeding, the bleeding may not stop completely, and the blood may seep into the subcutaneous layer, causing bruises. Therefore, pressing for a longer time can completely stop the bleeding. If there is a tendency of bleeding, the pressing time should be prolonged.

③ If you experience symptoms of needle phobia such as dizziness, blurred vision, fatigue, etc. after blood drawing, you should lie down immediately and drink a small amount of sugar water. Wait until the symptoms are relieved before undergoing a physical examination.

④ If local bruising occurs, apply a warm towel for wet compress after 24 hours to promote absorption. (3) Please inform your doctor of any recent medications and special physiological changes before the test.
