Levels can be found with a blood test approximately 11 days after conception, and a urine test approximately 12–14 days after conception.

A diagnosis should not be based solely on ultrasound observations until the hCG level has reached at least 2,000 mIU/mL because levels can vary greatly and conception dating can be inaccurate.
- Most diagnoses require more information than just one reading. When the health of the pregnancy is in doubt, several hCG tests conducted a few days apart provide a more accurate picture of the circumstances.
- Due to their extreme variability, hCG levels should not be utilized to determine the status of a pregnancy.
