Notes
- A single hCG number tells you very little, and the width of the range is the reason. At 5 weeks the published range runs from 18 to 7,340 mIU/mL — a span of roughly 408 times. Two entirely ordinary pregnancies at the same stage can differ by that much. A value inside the range is not reassurance and a value outside it is not a diagnosis; dating from a last menstrual period is itself often out by a week, which moves the comparison more than most results do.
- What carries information is the rate of rise, not the level. In early pregnancy hCG typically rises by at least 35 to 50% every 48 hours, and a common rule of thumb is roughly doubling. That is why the test is almost always ordered twice, two days apart: the pair says something the single value cannot. From this reading, a doubling would put the second result near 14,400 mIU/mL.
- Above roughly 1,500 to 2,000 mIU/mL an ultrasound generally takes over. Beyond that level a gestational sac is usually visible, and what the scan shows answers the question far better than more blood tests. hCG also stops being a useful guide after about 10 to 12 weeks, when it plateaus and then falls.
- This page compares a number to a published table. It cannot tell you anything about your pregnancy. Twins, dating error, the specific assay used and normal variation all move the figure, and only the clinician with the full picture — dates, symptoms, scan, and a second measurement — can interpret it.
An hCG of 7,200 mIU/mL at 5 weeks
At 5 weeks the widely published range runs from 18 to 7,340 mIU/mL. That is a span of roughly 408 times, and the width is the most important thing on this page.
A reading of 7,200 sits inside that range.
Why one number answers so little
Two entirely ordinary pregnancies at the same stage can differ by the full width of that range. Dating from a last menstrual period is itself commonly out by a week, which shifts the comparison more than most results do. Twins raise it. Different laboratories use different assays.
What clinicians actually read is the rate of rise. In early pregnancy hCG typically climbs by at least 35 to 50% every 48 hours, and roughly doubling is the common rule of thumb. That is why the test is nearly always ordered twice, two days apart — the pair says something a single value cannot. From this reading, a doubling would land near 14,400 mIU/mL.
Past roughly 1,500 to 2,000 mIU/mL an ultrasound generally takes over, because a gestational sac becomes visible and what the scan shows answers the question far better than more blood tests.
