  • Blood test—to check the exact amount of the hormone (called human chorionic gonadotropin or hCG) important to sustain an early pregnancy
After miscarriage, tests may include:
  • Examination of the tissue that has passed through the vagina
  • Blood tests—to check for a chromosomal error in the man or the woman or to check hormone and antibody levels
  • Imaging tests—(eg, x-rays , ultrasound ) to identify a problem with your uterus
  • Endometrial biopsy —to check the uterine lining to see if it can support a pregnancy
  • Hysteroscopy—to examine the inside of the uterus
