Beta-HCG

Beta-HCG (human chorionic gonadotropin) is a hormone produced by the placenta during pregnancy. It is used to confirm pregnancy and monitor its progression, as well as to detect certain tumors.

Category: Hormones

Also known as: beta-hcg, beta hcg, hcg, human chorionic gonadotropin, b-hcg, bhcg

Reference range: 0–5 mIU/mL (Source: ABIM)

Standard unit: mIU/mL

High values may indicate

High beta-HCG levels may indicate pregnancy (including multiple pregnancies), molar pregnancy, choriocarcinoma, or certain germ cell tumors of the ovaries or testes.

Low values may indicate

Low beta-HCG levels during pregnancy may indicate ectopic pregnancy, threatened miscarriage, or miscalculated gestational age. In non-pregnant individuals, low levels are normal.

Frequently asked questions

What is a normal Beta-HCG level?
A typical reference range for Beta-HCG is 0–5 mIU/mL (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
What units is Beta-HCG measured in?
Beta-HCG is most commonly reported in mIU/mL. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
Where do Beta-HCG reference ranges come from?
BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
Can I track Beta-HCG over time?
Yes. Upload results from any lab and BloodId charts your Beta-HCG over time against its reference range, so you can see whether the trend is rising, falling, or stable.
