Can elevated HCG levels after miscarriage mean retained tissue?

Yes, elevated human chorionic gonadotropin (hCG) levels after a miscarriage could indicate retained tissue. Following a miscarriage, hCG levels typically decline rapidly as the pregnancy products are expelled from the uterus. However, if there is any retained tissue, including placental fragments or embryonic material, it can continue to produce hCG, leading to elevated levels.

hCG monitoring is often used to track the resolution of pregnancy, and persistent elevated hCG levels beyond the expected timeframe can be a sign of retained tissue. This retained tissue can interfere with the complete shedding of pregnancy products and prevent the proper involution (shrinking) of the uterus.

In cases of suspected retained tissue, additional investigations such as ultrasound imaging or physical examination may be recommended to confirm the diagnosis and guide further management. If retained tissue is present, it may need to be removed through medical or surgical interventions to prevent complications and facilitate the healing process.
