What tests should be done during pre-pregnancy preparation?

Patient's question:

Gender: Female
Age: 24
I have been married for two years, and I had a pre-marital health check-up before marriage, with no issues found. I am planning to have a child now. Please advise if I need any check-ups before having a child, and what specific tests should be done?

Doctor's answer:

Hello: It is recommended that you undergo pre-natal screening.
Pre-natal examination items include general physical examinations, as well as blood and urine tests, hepatitis B surface antigen detection, and tests for some special pathogens. In areas with the necessary conditions, karyotype testing should be conducted to avoid genetic diseases.
Some special pathogens that need to be tested include Toxoplasma, rubella virus, cytomegalovirus, and herpes simplex virus, collectively known as TORCH.
