What do HCG blood test results mean?

Understanding HCG Blood Test Results

Human chorionic gonadotropin (HCG) is a hormone produced primarily by the placenta during pregnancy. HCG blood tests are commonly used to determine pregnancy status, assess gestational age, diagnose potential complications, and monitor conditions such as gestational trophoblastic disease.

What is HCG?

Human chorionic gonadotropin is a glycoprotein hormone produced by the placenta following implantation. The hormone supports the corpus luteum's production of progesterone during early pregnancy, which is crucial for maintaining the uterine lining and supporting embryonic growth.

Interpreting HCG Blood Test Results

HCG levels are measured in milli-international units per milliliter (mIU/mL). These levels vary significantly throughout pregnancy and can indicate various conditions based on their levels and progression trends.

Normal HCG Levels During Pregnancy

• 3 weeks: 5 - 50 mIU/mL
• 4 weeks: 5 - 426 mIU/mL
• 5 weeks: 18 - 7,340 mIU/mL
• 6 weeks: 1,080 - 56,500 mIU/mL
• 7-8 weeks: 7,650 - 229,000 mIU/mL
• 9-12 weeks: 25,700 - 288,000 mIU/mL
• 13-16 weeks: 13,300 - 254,000 mIU/mL
• 17-24 weeks: 4,060 - 165,400 mIU/mL
• 25-40 weeks: 3,640 - 117,000 mIU/mL

The levels typically double every 48 to 72 hours in early pregnancy, which is a critical indicator of a healthy pregnancy.

Interpreting Deviations in HCG Levels

HCG levels that deviate from the expected range can indicate various conditions:

• High HCG Levels: May indicate multiple pregnancies (twins, triplets), molar pregnancy, or, in some cases, a miscalculation of gestational age.
• Low HCG Levels: Can suggest potential issues such as a miscalculated gestational age, possible miscarriage, or ectopic pregnancy.
