   Seeing her coming, Ding Lulu raised the corner of her mouth and complained, "You asked me to come here earlier, but you were so slow yourself."

   She didn't make an appointment with this cousin at all, it was because the other party had a guilty conscience so she came early.

   Time is tight, Xie Wanying has no time to quarrel with the other party.

  Ding Lulu kept talking about herself for a long time, but when she didn't see her answer, she looked like she was drooling in vain. He could only wrinkle his nose and snort twice, turn around and follow her all the way to the blood bank.

   After registration, the two of them drove to the blood station center.

   Every day, many people come to donate blood voluntarily and consult about blood donation matters, and the medical staff in the blood station center are busy.

  According to the blood donation process guide board hanging in the blood station center, Xie Wanying went to get the form to fill in the form, and then went to measure the weight and blood pressure.

  These are the physical examinations that blood donors must do before donating blood. Some people who are underweight are not allowed to donate blood, nor are their blood pressure too high or too low.

   After the measurement, the weight is normal, and the blood pressure is normal, which is immediately followed by the rapid detection items.

  The doctor will **** the donor's finger with a needle, squeeze some blood from the blood vessel of the finger, and put it on the test strip to do several quick blood screenings. The detection here generally refers to the detection of blood group hemoglobin, liver function, blood group hepatitis B surface antigen and Treponema pallidum.

   Blood donors wait in the lobby for news before rapid test results come out. If several test results are qualified, it means that the blood of the donor is temporarily qualified to donate blood.

  Why is it said to be temporarily qualified? Because the blood collected from blood donors has to undergo a comprehensive laboratory test, including the rapid test on the spot, it will be done again to check whether the result is correct, in order to prevent mistakes. At the same time, it is necessary to add nucleic acid testing for HIV, hepatitis B and C, which cannot be tested quickly.

   As long as one of the above tests fails, the blood of the donor cannot be used for clinical patients. In the end, it is necessary to make the blood transfused to clinical patients as foolproof as possible. Blood transfusion-transmitted disease caused by blood transfusion is a very taboo thing in clinical practice.

When the quick test report such as the collection of finger blood was done, Ding Lulu's nagging mouth did not stop, and she said to Xie Wanying, "I'll make it clear to you first. I came to donate blood all because of my cousin, not because of you, you. Do you hear clearly?"

   That’s how it was. Xie Wanying knew that this cousin was too nervous so she nagged and didn't argue with her.

   Sure enough, Ding Lulu explained to her again: "I may not be able to donate blood. If my blood is unqualified, I can't donate blood to my cousin. You can't blame me."

   Is this cousin saying that she is cursing her body for having a blood-borne infectious disease? Xie Wanying turned her head, two eyes swept across Ding Lulu's face.

  Ding Lulu realized what she meant by her eyes, her eyes were red on the spot, and she clarified: "Of course my blood is not infectious."

   If there is no infectious disease, you must be qualified, why can't you donate blood? Xie Wanying tickled the corner of her mouth and turned back.

   "I'm underweight." Ding Lulu found another reason for herself not to donate blood.

   The blood station staff heard her words, and immediately turned over the weight value of her physical examination and said to her: "Your weight is calculated according to your current height and age, which is within the normal range."
