Pregnancy Blood Test
May 11, 2026
Pregnancy Blood Test
A pregnancy blood test measures hCG (human chorionic gonadotropin) in your blood to confirm pregnancy with greater accuracy and earlier detection than urine tests—detecting pregnancy as early as 6-8 days after ovulation and providing a quantitative result that can help assess whether the pregnancy is progressing normally.
At Blood Test London, pregnancy testing costs from £245 with results in 2-3 days. A doctor always reviews every result.

Accuracy | 99%+ | 97-99% if done correctly |
Quantitative | Yes (exact level) | No (positive/negative only) |
Tracks progression | Yes (serial testing) | No |
False negatives | Very rare | More common if early |
Understanding hCG Levels
Weeks Since LMP | Typical hCG Range (mIU/mL) |
|---|---|
3 weeks | 5-50 |
4 weeks | 50-500 |
5 weeks | 100-5,000 |
6 weeks | 500-10,000 |
7-8 weeks | 5,000-100,000 |

hCG typically doubles every 48-72 hours in early pregnancy.
