Prenatal check-up for mycoplasma for a few weeks
Mycoplasma testing is usually recommended for pregnant women after 12 weeks of pregnancy. Mycoplasma testing can be done through examination in the first, second and late trimesters, cervical mucus smear, biochemistry, cytology, antigen and antibody measurements, to find out whether there is mycoplasma infection in pregnant women, to avoid intrauterine infection and adverse pregnancy outcomes.
1. Early pregnancy: It is recommended that pregnant women be tested for mycoplasma after 12 weeks, when the embryo has been formed in the fetal uterine cavity, and the placental trophoblast cells begin to secrete β-HCG, which can be measured by immune response, and if mycoplasma is found to be positive, it can be diagnosed as mycoplasma infection;
2. Second trimester: that is, at 16-20 weeks of pregnancy, the first prenatal B-ultrasound screening is required to exclude fetal chromosomal abnormalities, and the second screening is carried out to determine whether there is recent mycoplasma infection;
3. Late pregnancy: that is, at 28-32 weeks of pregnancy, a second ultrasound screening is required to determine whether the fetus has growth restriction and malformations, and at this time, sputum culture and serological testing can be used to screen for mycoplasma infection.
Mycoplasma testing is indicated in pregnant women who are pregnant with normal pregnancy and if the first prenatal ultrasound screen suggests mycoplasma infection, regardless of whether they are clinically asymptomatic. If you have a history of cervicitis, or if you have symptoms of vaginitis, or if you have symptoms after an upper respiratory tract infection, or if you have amnionitis or premature rupture of membranes, you should be tested again to check for mycoplasma infection.
For pregnant women with prior mycoplasma infection, testing for antigens and antibodies is also recommended postpartum to determine whether there is recurrent infection.
For high-risk pregnancies, i.e., those with a history of adverse pregnancy outcomes, mycoplasma testing is indicated before labor or after a trial of labour in the vagina. If the test is positive, aggressive treatment is required to reduce the incidence of adverse pregnancy outcomes.
