Understanding hCG Levels: Normal Ranges in Pregnancy

Introduction

  • Human Chorionic Gonadotropin (hCG) is a hormone produced during pregnancy. It plays a crucial role in supporting the early stages of pregnancy by stimulating the production of progesterone.

  • Monitoring beta hCG levels in pregnancy helps confirm pregnancy and assess fetal health.

  • This guide will explain hCG levels by week of pregnancy, what’s considered normal, and when to consult a doctor.

What Level of hCG is Considered Pregnant?

  • A beta hCG level above 5 mIU/mL suggests a possible pregnancy, while levels above 25 mIU/mL confirm pregnancy.

  • Home pregnancy tests detect hCG in urine, but blood tests provide more precise results.

  • Learn more about hCG levels and pregnancy confirmation from New World Fertility Center.

hCG Levels When Not Pregnant

  • A normal hCG level in a non-pregnant woman is typically less than 5 mIU/mL.

  • Elevated hCG levels without pregnancy may indicate medical conditions like tumors, hormonal imbalances, or recent fertility treatments.

Beta hCG Levels by Pregnancy Week

1 Week Pregnant hCG Levels

  • At this stage, hCG is not yet detectable, as implantation has not yet occurred.

2 Weeks Pregnant hCG Levels

  • hCG levels start at 5–50 mIU/mL, depending on when implantation happens.

3 Weeks Pregnant hCG Levels

  • hCG levels range from 5–50 mIU/mL, with possible early detection via a sensitive blood test.

4 Weeks Pregnant hCG Levels (First Missed Period)

  • hCG range: 10–750 mIU/mL.

  • Home pregnancy tests are usually positive by this time.

  • Find detailed hCG level charts and pregnancy tracking at American Pregnancy Association.

5 Weeks Pregnant hCG Levels

  • hCG levels increase significantly to 217–7,138 mIU/mL.

  • The hormone should double every 48–72 hours in a healthy pregnancy.

6 Weeks Pregnant hCG Levels

  • Levels rise rapidly: 152–32,177 mIU/mL.

  • At this stage, pregnancy symptoms become more prominent.

Symptoms of Rising hCG Levels

  • Common Symptoms:
