Beta hCG Levels Chart by Week: What the Numbers Actually Mean
A beta hCG levels chart by week, how doubling time works, and why the exact number matters less than the trend over time.
Beta hCG is the hormone at the center of every early pregnancy blood test. Searching for a beta hCG levels chart usually means you have a number in hand and want to know if it looks normal. The honest answer is that hCG ranges are extremely wide, and a single number tells you far less than how that number changes over time.
What the Beta hCG Levels Chart Shows
A beta hCG levels chart shows the typical range of hCG hormone concentration in the blood at each week of early pregnancy, measured in mIU/mL. These ranges are extremely wide, meaning a low or high number within the range is not itself a cause for concern. What matters more clinically is the trend: whether hCG is rising appropriately over 48 to 72 hours in very early pregnancy, a pattern known as doubling time, rather than the single number on any one day.
Beta hCG Levels by Week of Pregnancy
| Weeks since last menstrual period | Typical hCG range (mIU/mL) |
|---|---|
| 3 weeks | 5 to 50 |
| 4 weeks | 5 to 426 |
| 5 weeks | 18 to 7,340 |
| 6 weeks | 1,080 to 56,500 |
| 7 to 8 weeks | 7,650 to 229,000 |
| 9 to 12 weeks | 25,700 to 288,000 |
| 13 to 16 weeks | 13,300 to 254,000 |
Notice how wide each range is, particularly from week 5 onward. This is completely normal and expected. A number at the low end of the range is not inherently more concerning than a number at the high end, as long as it is rising appropriately over time.

Why Beta hCG Levels Vary So Much Between Women
The huge range in the chart above reflects real, normal biological variation. Ovulation timing, implantation timing, and individual differences in how quickly the body produces hCG all affect where a specific person falls within these ranges. This is precisely why comparing your number to a friend's number at the "same" point in pregnancy is not meaningful, since due dates and actual conception timing frequently differ even when both women assume the same week.
When a Beta hCG Pattern Needs Medical Attention
This chart is educational and does not replace personalised medical advice. A beta hCG levels chart cannot diagnose ectopic pregnancy, miscarriage, or confirm a healthy pregnancy on its own. Abnormal doubling patterns still occur in some perfectly healthy pregnancies, and normal patterns do not guarantee a complication-free outcome. Always have your specific results interpreted by a doctor who knows your full clinical picture, rather than comparing numbers to a general chart.
