Can tertiary hospitals perform appraisals?

Patient's question:

What you said is that amniocentesis can only be performed in tertiary hospitals? I can request amniocentesis to extract amniotic fluid at a large hospital's obstetrics department, right? Does the procedure require an advance reservation? Is rest required after the surgery? Can tertiary hospitals perform the test directly?

Doctor's answer:

Disease Analysis
Amniocentesis is a method of prenatal diagnosis, generally suitable for mid-pregnancy. Amniocentesis is a preliminary measure for diagnosing fetal gender, genetic diseases, and paternity testing. The procedure is typically performed between 15-20 weeks of pregnancy, with the latest not exceeding 22 weeks. The will not injure the fetus or cause fetal abnormalities. Generally, amniotic fluid testing can be done in third-class hospitals.
Guidance for Treatment
1. Abstain from sexual intercourse for three days before the procedure; take a shower the day before; empty your bladder completely 10 minutes before the procedure.
2. If you have had a cold, fever, skin infection, or other abnormalities within 3-7 days before the procedure, please inform the doctor during pre-procedure registration.
3. If you have a history of allergies, special diseases, or other conditions requiring attention, please inform the doctor during pre-procedure registration.
4. After the procedure, you must rest for at least 2 hours before taking a taxi home; out-of-town patients are advised to stay in the city overnight.
5. Do not shower within 24 hours after the procedure; rest more, avoid strenuous exercise, and refrain from heavy physical labor such as moving heavy objects.
6. Abstain from sexual intercourse for half a month after the procedure.
7. If you experience abdominal pain, bloating, vaginal discharge, bleeding, or fever within three days after the procedure, these are signs of a dangerous pregnancy condition. Please seek immediate medical attention at the obstetrics and gynecology department of the hospital.
