The preliminary tests done this week include:

  • Hepatitis B, syphilis, and HIV
  • Anemia (lower count of red blood cells)
  • Cystic fibrosis
  • Immunity to chickenpox (varicella) and German measles (rubella) (looks for the antigens)
  1. Urine test helps determine the protein and sugar level.
  1. Blood pressure and weight are checked.
  1. A vaginal examination, called Pap smear test, is done if you are due for it. The cervix will be dabbed with a cotton swab, and the sample will be tested to check for sexually transmitted diseases (STDs) such as gonorrhea and chlamydia.
  1. An ultrasound done in this week will show two fetal poles in the case of twin pregnancy.
