Which blood type of women will not age easily?

Female friends are all afraid of aging faster, but aging is a normal physiological law of human beings and there is no way to avoid it. Moreover, whether you are prone to aging has little to do with blood type. It is mainly related to your mood, life and work. If your work is too busy or you are in an anxious state, your body functions will age faster.

People with type A blood have a strong desire to lead, are good at fighting, and have the ability to achieve their goals. They firmly believe in their own strength and are easily impulsive and lose self-control when they feel intense jealousy and overly conceited.

People with type B blood are calm, serious, patient, kind-hearted and sentimental. Sometimes they are also stubborn and high-strung.

People with type O blood are stable, sensible and have a strong sense of justice. The only drawback is that he is sometimes impatient and hesitant in handling matters.

The number of people with AB type blood is extremely small, and researchers know little about it. Their personalities remain a mystery.

(1) Slide method ① Add 1 drop of anti-D reagent on the slide. ② Add another drop of 35-45% red blood cell suspension to be tested. The red blood cell suspension may be a saline suspension or red blood cells suspended in autologous plasma or serum. ③ Gently shake the slide and observe the results with the naked eye. If agglutination occurs, it means the D antigen is present on the red blood cells being tested, which indicates Rh(D) positivity. If there is no agglutination, it indicates Rh(D) negative. ④ If the result is negative, the test needs to be repeated using the test tube method. (2) Test tube method ① Add 1 drop of anti-D reagent to a pre-labeled test tube. ② Add another drop of about 5% of the red blood cell suspension to be tested into the test tube. Mix well. ③ Centrifuge immediately at 1000r/min for 1 min.

④ Observe the results with the naked eye. In completely agglutinated tubes, the liquid is clear, with red blood cell clots on the bottom. The cells on the bottom of the tube are lace-like, and the clots do not disperse when the test tube is tapped lightly. In completely unagglutinated tubes, the liquid surface is clear, and the blood cells sink evenly to the bottom of the tube with neat edges. When the test tube is tapped lightly with a finger, the red blood cells immediately rise like a wisp of smoke and then become a uniform suspension. In cases of slight agglutination, the liquid must be transferred to a slide for microscopic examination before making a decision.

⑤ If agglutination occurs, it means that the D antigen Rh(D) is present on the red blood cells being tested, and if there is no agglutination, it means that the red blood cells are Rh(D) positive.
