How high can hCG levels get with a chemical pregnancy?
HCG levels in pregnancy HCG levels higher than 5 million international units per milliliter (mIU/mL) typically indicate pregnancy. Your first test result is considered a baseline level. This level can range from very small amounts of hCG (such as 20 mIU/mL or even lower) to larger amounts (such as 2,500 mIU/mL).
What else can cause high hCG levels?
Apart from pregnancy, there are other gynaecological conditions that can cause an elevated serum hCG. Gestational trophoblastic diseases such as hydatidiform moles, gestational trophoblastic neoplasias, and choriocarcinomas are diseases where hCG is elevated and the hCG ratio changes in favour of free hCGβ [9].
What should your hCG levels be at 4 weeks?
Standard hCG levels

|---|---|
| 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 |
