Beta HCG Test – Reference Range

Beta HCG (human chorionic gonadotropin) and AFP (alpha fetoprotein) are both tumor markers used in detecting testicular cancer, and in monitoring the response of the cancer to treatment.

The normal value for Beta HCG is less than 5 mU/ml and for AFP it is 0-44 ng/ml. Normal beta HCG levels can vary widely from woman to woman. The medical community typically looks at normal ranges rather than a specific level.

It’s important to understand that normal readings fall within a very wide range, and knowing this ahead of time may help you avoid feeling panic.

Here are the typical normal 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
  • 7-8 weeks: 7,650 – 229,000 mIU/ml
  • 9-12 weeks: 25,700- 288,000 mIU/ml
  • 13-16 weeks: 13,300 – 254,00 mIU/ml
  • 17-24 weeks: 4,060 – 165,400 mIU/ml
  • 25-40 weeks: 3,640 – 117,000 mIU/ml

The mIU/ml unit stands for milli-international units per milliliter. A positive pregnancy test looks for levels above 25 mIU/ml.
