Quick answer
Your beta-hCG level is 805.7 mIU/mL.
- This is positive for pregnancy, since the non-pregnant reference is below 5 mIU/mL.
- A single hCG value cannot accurately date a pregnancy because normal ranges overlap widely. On this laboratory’s table, it falls within ranges reported around 4 to 5 weeks from the first day of the last menstrual period (LMP).
- It does not by itself confirm that the pregnancy is inside the uterus, viable, or progressing normally.
Usual next steps
- Repeat quantitative beta-hCG in about 48 hours, if advised by your clinician. In a normally developing early intrauterine pregnancy, the level generally rises substantially over this interval, though it does not need to exactly double.
- Arrange obstetric/gynecology follow-up. A transvaginal ultrasound may not yet clearly show a gestational sac at this level; it is usually more informative once hCG is higher or based on your dates.
Seek urgent care now if you have one-sided or severe lower abdominal pain, shoulder-tip pain, fainting/dizziness, or heavy vaginal bleeding, because these can be warning symptoms of ectopic pregnancy or miscarriage.

ACOG hCG levels early pregnancy single hCG cannot determine gestational age
Based on the beta-hCG level of 805.7 mIU/mL, it most closely fits approximately 4 to 5 weeks of pregnancy counted from the first day of your last menstrual period (LMP). In your lab’s reference chart, it is just above the stated 4-week range and within the 5-week range.
That would roughly correspond to conception about 2 to 3 weeks ago, because pregnancy weeks are counted from the LMP, not from conception.
However, hCG ranges overlap a lot, so one blood result cannot date a pregnancy accurately. The best dating comes from your LMP plus an early ultrasound, as recommended by ACOG’s due-date guidance.

ACOG pregnancy dating first trimester ultrasound crown rump length accurate gestational age
The best test to determine the pregnancy period is a first-trimester ultrasound, preferably a transvaginal ultrasound this early.
- It measures the embryo’s crown-rump length (CRL) once visible.
- When done from about 6 to 13 weeks 6 days, it estimates pregnancy age most accurately, usually within about 5 to 7 days. The medical textbook source similarly notes CRL at 6-12 weeks predicts gestational age within about 3-4 days. ACOG guidance
- Your LMP date is also used, but ultrasound is more reliable if periods are irregular or the date is uncertain.
With hCG 805.7 mIU/mL, an ultrasound may be too early to see enough for precise dating. Your clinician may repeat quantitative beta-hCG after 48 hours and arrange the ultrasound in about 1-2 weeks, or earlier if you have pain or bleeding. A repeat hCG helps assess the trend, but it is not the best test for exact dating.
