What is the antibody test?

Pregnancy is a very difficult thing, but the mood during pregnancy is indeed happy. If you want to have a healthy baby, you need to do various examinations during pregnancy to help identify the growth and development of the fetus. You need to do a thorough checkup after pregnancy. Some people will check for antigens after pregnancy, so what is the purpose of checking for antibodies? Let me explain it to you in detail below.

What does it mean to test for antibodies during pregnancy?

There are many kinds of antigens in the human body, and testing different resistances will have different clinical manifestations. You simply said that the antigen was tested, but did not specify which antigen was actually tested, so there is no way to give you further clarification. For example, testing the hepatitis B virus surface antigen is mainly to check whether there is immunity to the hepatitis B virus; if the toxin coccal antigen is tested, it is to check whether there is infection with Treponema pallidum. Therefore, the details need to be further clarified by presenting an inspection report.

Pregnancy can usually be checked with early pregnancy test strips to determine whether you are pregnant. In addition, you can do a blood HCG test to determine whether you are pregnant. If you have hepatitis B, you can check the five indicators of hepatitis B to see if there is antigen. Men's sperm and seminal plasma are specific antigens for women. After coming into contact with blood, both men and women can produce an immune response, producing corresponding antigens, which prevent sperm from combining with egg cells and cause infertility. The uterine wall is the island where the fertilized egg implants and develops, but in pathological conditions, such as endometritis, endometriosis and adenomyosis, it can be converted into antigens or haptens, stimulating the body itself to produce corresponding antigens.

In addition, during abortion surgery with curettage, the gestational sac may also act as an antigen to stimulate the body to produce antibodies. Once anti-uterine wall antigens exist in a woman's body, it will cause infertility, pregnancy arrest or miscarriage. The treatment method is to use condoms to separate male sperm from female contact, making it less likely for new anti-sperm antibodies to be produced, and the original antigens can gradually disappear. Antisperm antibodies can block sperm and eggs, causing complement-mediated fusion of sperm and egg, affecting embryo implantation and early embryonic development, and causing miscarriage in early pregnancy. Cytotoxic effect, based on complement-mediated, phagocytosis of male sperm. Anti-sperm antibodies combine with cervical mucus proteins to prevent male sperm from crossing the cervical mucus. Antisperm antibodies can affect sperm capacitation and acrosome reaction, and affect the fitness movement of male sperm.

What tests should be done during pregnancy

In the early stages of pregnancy, you will need to have blood tests and B-ultrasound to see whether the pregnancy is inside or outside the uterine cavity. In fact, it is best to go on an empty stomach for the first few examinations to avoid having a bad breakfast and having to wait for the next time. It is recommended that you pay attention to the combination of rest and nutrition. Avoid spicy food and cold food. Generally speaking, in the early stages of pregnancy, that is, within three months to 12 weeks, you need to go to a large hospital for a physical examination to determine the due date and the growth and development of the fetus, so that any problems can be dealt with immediately! Basically, you can go to the hospital for a check-up and book an ultrasound when you are about seven weeks pregnant. If you do an ultrasound around seven or eight weeks, you can see the ovarian sac, embryonic bud and fetal heartbeat.

The registration is established at 12 weeks of pregnancy, and generally some blood, urine, intravenous injection and other five tests are required when applying for the perinatal certificate. Do Down syndrome screening at 14-20 weeks. Do an ultrasound every 20 weeks. After that, there will be inspections at 24 weeks, 28 weeks, 30 weeks, 32 weeks, 34 weeks, 36 weeks, 37 weeks, 38 weeks, 39 weeks and 40 weeks. Each time you check your weight and blood pressure, you will usually have a blood test and a urine test. At 30 weeks, we start measuring uterine height, fetal abdominal circumference, and listening to the fetal heartbeat. , a 3D B-ultrasound is performed at 20 weeks and 30 weeks, and a color ultrasound is performed at 36 weeks. Every fetal heartbeat check starts at 36 weeks.
